'''SMDegrain''', the Simple MDegrain Mod, is mainly a convenience function for using [[MVTools]]. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original '''SMDegrain()''' by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) MDegrain denoising.
* '''Higher temporal radius''' (tr>3): The [[MVTools]] mod (and hence this script) also allows for hack-free higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A ''CClip'' parameter is also supplied so you can choose another source to sharpen from, other than the default '''SMDegrain()''' input.
* '''YUY2 support''': It automatically and fully supports YUY2.
* '''Interlaced support''': It supports interlaced sources with most parameters as well.
* '''Extended Subpixel Accuracy''': [[nnedi3]] is allowed as a subpixel filter, not necessary in most cases, but if you are quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where '''SMDegrain()''' couldn't find a matching block for denoising. One use for it would be spatial denoisers or deblockers since high-motion areas are prone to heavy blocking and artifacts.
* '''Global Motion Vector In/Out''': Reuse motion vectors globals for faster processing, or just use '''SMDegrain()''' as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): Slower, but sometimes a big quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for '''SMDegrain()''' being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see [http://forum.doom9.org/showthread.php?p=1544619#post1544619 this] and ''prefilter'' notes), but those are the rare cases.

To picture what the function does, a simple '''SMDegrain()''' call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (''Dither_Luma_Rebuild''(S0=1.0,c=0.0625) similar to ''color_yuv''(levels="TV->PC")) so you have more range to detect motion vectors, the ''rfilter''=4 for a bit more quality super search, the changed default of ''overlap'' from 0 to 4 and ''thSAD'' and ''thSADC'' from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for '''SMDegrain()'''.

==Using the filter==
*Input can be YV12 or YUY2, and '''must''' be TV range (which is normal). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary.
*Crop first (when not interlaced).
*Recommended to deblock if blocking is present, before crop (when cropping) and '''SMDegrain()'''. Or you can use ''prefilter''=3 which is also a good deblocker (dfttest) and let '''SMDegrain()''' clean the blocking for you.
*Default output mode(dithering) for ''lsb''=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use ''mode''=6 (error diffusion) or ''lsb_out''=true and keep filtering in 16bit
*Read the ''prefilter'' setting explanation for solutions to problematic sources

==Ready-to-run Samples==

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

A basic, fast, yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; ''pel''=1, ''hpad''=0, ''vpad''=0, ''blksize''=32, ''overlap''=16, ''truemotion''=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add ''truemotion''=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for ''contrasharp''.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

==Parameters==
{{FuncDef|SMDegrain}} (clip input, int "tr", int "thSAD", int "thSADC", bool "RefineMotion", val "contrasharp", clip "CClip", bool "interlaced", int "plane", int "Globals", int "pel", int "subpixel", val "prefilter", clip "mfilter", int "blksize", int "overlap", int "search", bool "truemotion", int "limit", int "limitc", int "thSCD1", int "thSCD2", bool "chroma", int "hpad", int "vpad", bool "lsb", bool "lsb_in", bool "lsb_out", int "mode", val "Show", float "Str", float "Amp")

===Basic===

{{ParR|tr|int|2|1-128}}
:Temporal radius, selects the MDegrain to use. This can be considered the strength of the denoising. Higher is generally better, but also much slower and each extra frame gives less improvement.
:tr 4+ requires Dither's MVTools2 mod. Max 64 for interlaced.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (''blksize''). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise ''blksize'', which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the "sharp" clip is the input, the "after" clip is the denoised clip. Alternately, a "before" clip can be specified with ''CClip'' (See Advanced).
:*True: use Didée's Contrasharpening() function (ContraHD() for HD) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:*An integer: LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.

{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a ''prefilter'' so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with ''lsb_out''=true then you will have to <tt>Weave().DitherPost(mode=6,interlaced=true)</tt> when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+. The [[VapourSynth]] version doesn't use these parameters; it automatically outputs the same bitdepth as the input.

{{Par|lsb_in|bool|False}}
:Set true if you use a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:Output to 16-bit instead of 8-bit. Use the helpers at the end of the SMDegrain() script to use Ditherpost() with YUY2 formats.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas. Automatically set if either ''lsb_in'' or ''lsb_out'' are enabled.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]] when ''lsb_out''=False, as a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default ''mode''=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use ''mode''=6 (error diffusion) if further processing will be done.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for ''pel''=2 or 4. This is the 'sharp' parameter in MSuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try ''prefilter''=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources ''prefilter''=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use ''lsb_in'', ''lsb_out'' according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in [http://forum.doom9.org/showthread.php?t=162813 Doom9] for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a ''prefilter'' as well. Or at last and the recommended solution, to use the built-in ''Str'' (strength) and ''Amp'' (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")
:Good resources for custom prefilters:

:*http://forum.doom9.org/showthread.php?t=133977
:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no ''thSAD'' tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), [http://forum.doom9.org/showthread.php?p=1544619#post1544619 Multilevel MDegrain], etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the ''prefilter'' clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Used when ''Str'' <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and ''Str'' are extrapolated arguments from [http://forum.doom9.org/showthread.php?p=1548318#post1548318 cretindesalpes' function], you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling ''show''.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common values: ''blksize''/4 or ''blksize''/2. Larger ''overlap'' looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:''Truemotion'' is a preset of some MVAnalyze parameter values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|''blksize'' for SD, 0 for HD}}
{{Par|Vpad|int|''blksize'' for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on ''blksize'': 4{{=}}>100, 8{{=}}>400, 16{{=}}>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, first try ''Str'' and ''Amp''.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for ''contrasharp'' to compare against; video resolution and properties must be the same (different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: '''Super''', '''bv1''', '''fv1''', '''bv2''', '''fv2''', '''bv3''', '''fv3''', '''bv4''', '''fv4''', '''bv6''', '''fv6''', '''vmulti'''.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. ''lsb_in''=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using ''Globals''=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with ''Str'' and ''Amp'' parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any MSuper(). Therefore if you are not processing chroma (''chroma''=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are unset. In this regard for previewing tasks with prefilterings -- or just the ''Str'' and ''Amp'' effect -- set ''chroma'' to true temporally or follow with ''GreyScale''(). For YUY2 sources set ''Planar2Interleaved''() after cropping for previewing.

'''SMDegrain''', the Simple MDegrain Mod, is mainly a convenience function for using [[MVTools]]. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original '''SMDegrain()''' by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) MDegrain denoising.
* '''Higher temporal radius''' (tr>3): The [[MVTools]] mod (and hence this script) also allows for hack-free higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A ''CClip'' parameter is also supplied so you can choose another source to sharpen from, other than the default '''SMDegrain()''' input.
* '''YUY2 support''': It automatically and fully supports YUY2.
* '''Interlaced support''': It supports interlaced sources with most parameters as well.
* '''Extended Subpixel Accuracy''': [[nnedi3]] is allowed as a subpixel filter, not necessary in most cases, but if you are quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where '''SMDegrain()''' couldn't find a matching block for denoising. One use for it would be spatial denoisers or deblockers since high-motion areas are prone to heavy blocking and artifacts.
* '''Global Motion Vector In/Out''': Reuse motion vectors globals for faster processing, or just use '''SMDegrain()''' as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): Slower, but sometimes a big quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for '''SMDegrain()''' being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see [http://forum.doom9.org/showthread.php?p=1544619#post1544619 this] and ''prefilter'' notes), but those are the rare cases.

To picture what the function does, a simple '''SMDegrain()''' call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (''Dither_Luma_Rebuild''(S0=1.0,c=0.0625) similar to ''color_yuv''(levels="TV->PC")) so you have more range to detect motion vectors, the ''rfilter''=4 for a bit more quality super search, the changed default of ''overlap'' from 0 to 4 and ''thSAD'' and ''thSADC'' from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for '''SMDegrain()'''.

==Using the filter==
*Input can be YV12 or YUY2, and '''must''' be TV range (which is normal). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary.
*Crop first (when not interlaced).
*Recommended to deblock if blocking is present, before crop (when cropping) and '''SMDegrain()'''. Or you can use ''prefilter''=3 which is also a good deblocker (dfttest) and let '''SMDegrain()''' clean the blocking for you.
*Default output mode(dithering) for ''lsb''=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use ''mode''=6 (error diffusion) or ''lsb_out''=true and keep filtering in 16bit
*Read the ''prefilter'' setting explanation for solutions to problematic sources

==Ready-to-run Samples==

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

A basic, fast, yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; ''pel''=1, ''hpad''=0, ''vpad''=0, ''blksize''=32, ''overlap''=16, ''truemotion''=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add ''truemotion''=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for ''contrasharp''.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

==Parameters==
{{FuncDef|SMDegrain}} (clip input, int "tr", int "thSAD", int "thSADC", bool "RefineMotion", val "contrasharp", clip "CClip", bool "interlaced", int "plane", int "Globals", int "pel", int "subpixel", val "prefilter", clip "mfilter", int "blksize", int "overlap", int "search", bool "truemotion", int "limit", int "limitc", int "thSCD1", int "thSCD2", bool "chroma", int "hpad", int "vpad", bool "lsb", bool "lsb_in", bool "lsb_out", int "mode", val "Show", float "Str", float "Amp")

===Basic===

{{ParR|tr|int|2|1-128}}
:Temporal radius, selects the MDegrain to use. This can be considered the strength of the denoising. Higher is generally better, but also much slower and each extra frame gives less improvement.
:tr 4+ requires Dither's MVTools2 mod. Max 64 for interlaced.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (''blksize''). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise ''blksize'', which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the "sharp" clip is the input, the "after" clip is the denoised clip. Alternately, a "before" clip can be specified with ''CClip'' (See Advanced).
:*True: use Didée's Contrasharpening() function (ContraHD() for HD) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:*An integer: LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.

{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a ''prefilter'' so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with ''lsb_out''=true then you will have to <tt>Weave().DitherPost(mode=6,interlaced=true)</tt> when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+.

{{Par|lsb_in|bool|False}}
:Set true if you use a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:Output to 16-bit instead of 8-bit. Use the helpers at the end of the SMDegrain() script to use Ditherpost() with YUY2 formats.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas. Automatically set if either ''lsb_in'' or ''lsb_out'' are enabled.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]] when ''lsb_out''=False, as a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default ''mode''=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use ''mode''=6 (error diffusion) if further processing will be done.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for ''pel''=2 or 4. This is the 'sharp' parameter in MSuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try ''prefilter''=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources ''prefilter''=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use ''lsb_in'', ''lsb_out'' according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in [http://forum.doom9.org/showthread.php?t=162813 Doom9] for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a ''prefilter'' as well. Or at last and the recommended solution, to use the built-in ''Str'' (strength) and ''Amp'' (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")

:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no ''thSAD'' tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), [http://forum.doom9.org/showthread.php?p=1544619#post1544619 Multilevel MDegrain], etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the ''prefilter'' clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Used when ''Str'' <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and ''Str'' are extrapolated arguments from [http://forum.doom9.org/showthread.php?p=1548318#post1548318 cretindesalpes' function], you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling ''show''.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common values: ''blksize''/4 or ''blksize''/2. Larger ''overlap'' looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:''Truemotion'' is a preset of some MVAnalyze parameter values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|''blksize'' for SD, 0 for HD}}
{{Par|Vpad|int|''blksize'' for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on ''blksize'': 4{{=}}>100, 8{{=}}>400, 16{{=}}>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, first try ''Str'' and ''Amp''.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for ''contrasharp'' to compare against; video resolution and properties must be the same (different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: '''Super''', '''bv1''', '''fv1''', '''bv2''', '''fv2''', '''bv3''', '''fv3''', '''bv4''', '''fv4''', '''bv6''', '''fv6''', '''vmulti'''.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. ''lsb_in''=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using ''Globals''=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with ''Str'' and ''Amp'' parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any MSuper(). Therefore if you are not processing chroma (''chroma''=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are unset. In this regard for previewing tasks with prefilterings -- or just the ''Str'' and ''Amp'' effect -- set ''chroma'' to true temporally or follow with ''GreyScale''(). For YUY2 sources set ''Planar2Interleaved''() after cropping for previewing.

'''SMDegrain''', the Simple MDegrain Mod, is mainly a convenience function for using [[MVTools]]. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original '''SMDegrain()''' by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) MDegrain denoising.
* '''Higher temporal radius''' (tr>3): The [[MVTools]] mod (and hence this script) also allows for hack-free higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A ''CClip'' parameter is also supplied so you can choose another source to sharpen from, other than the default '''SMDegrain()''' input.
* '''YUY2 support''': It automatically and fully supports YUY2.
* '''Interlaced support''': It supports interlaced sources with most parameters as well.
* '''Extended Subpixel Accuracy''': [[nnedi3]] is allowed as a subpixel filter, not necessary in most cases, but if you are quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where '''SMDegrain()''' couldn't find a matching block for denoising. One use for it would be spatial denoisers or deblockers since high-motion areas are prone to heavy blocking and artifacts.
* '''Global Motion Vector In/Out''': Reuse motion vectors globals for faster processing, or just use '''SMDegrain()''' as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): Slower, but sometimes a big quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for '''SMDegrain()''' being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see [http://forum.doom9.org/showthread.php?p=1544619#post1544619 this] and ''prefilter'' notes), but those are the rare cases.

To picture what the function does, a simple '''SMDegrain()''' call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (''Dither_Luma_Rebuild''(S0=1.0,c=0.0625) similar to ''color_yuv''(levels="TV->PC")) so you have more range to detect motion vectors, the ''rfilter''=4 for a bit more quality super search, the changed default of ''overlap'' from 0 to 4 and ''thSAD'' and ''thSADC'' from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for '''SMDegrain()'''.

==Using the filter==
*Input can be YV12 or YUY2, and '''must''' be TV range (which is normal). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary.
*Crop first (when not interlaced).
*Recommended to deblock if blocking is present, before crop (when cropping) and '''SMDegrain()'''. Or you can use ''prefilter''=3 which is also a good deblocker (dfttest) and let '''SMDegrain()''' clean the blocking for you.
*Default output mode(dithering) for ''lsb''=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use ''mode''=6 (error diffusion) or ''lsb_out''=true and keep filtering in 16bit
*Read the ''prefilter'' setting explanation for solutions to problematic sources

==Ready-to-run Samples==

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

A basic, fast, yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; ''pel''=1, ''hpad''=0, ''vpad''=0, ''blksize''=32, ''overlap''=16, ''truemotion''=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add ''truemotion''=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for ''contrasharp''.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

:Temporal radius, selects the MDegrain to use. This can be considered the strength of the denoising. Higher is generally better, but also much slower and each extra frame gives less improvement.
:tr 4+ requires Dither's MVTools2 mod. Max 64 for interlaced.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (''blksize''). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise ''blksize'', which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the "sharp" clip is the input, the "after" clip is the denoised clip. Alternately, a "before" clip can be specified with ''CClip'' (See Advanced).
:*True: use Didée's Contrasharpening() function (ContraHD() for HD) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:*An integer: LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.

{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a ''prefilter'' so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with ''lsb_out''=true then you will have to <tt>Weave().DitherPost(mode=6,interlaced=true)</tt> when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+.

{{Par|lsb_in|bool|False}}
:Set true if you use a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:Output to 16-bit instead of 8-bit. Use the helpers at the end of the SMDegrain() script to use Ditherpost() with YUY2 formats.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas. Automatically set if either ''lsb_in'' or ''lsb_out'' are enabled.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]] when ''lsb_out''=False, as a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default ''mode''=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use ''mode''=6 (error diffusion) if further processing will be done.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for ''pel''=2 or 4. This is the 'sharp' parameter in MSuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try ''prefilter''=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources ''prefilter''=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use ''lsb_in'', ''lsb_out'' according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in [http://forum.doom9.org/showthread.php?t=162813 Doom9] for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a ''prefilter'' as well. Or at last and the recommended solution, to use the built-in ''Str'' (strength) and ''Amp'' (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")
:Good resources for custom prefilters:

:*http://forum.doom9.org/showthread.php?t=132310
:*http://forum.doom9.org/showthread.php?t=133977
:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no ''thSAD'' tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), [http://forum.doom9.org/showthread.php?p=1544619#post1544619 Multilevel MDegrain], etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the ''prefilter'' clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Used when ''Str'' <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and ''Str'' are extrapolated arguments from [http://forum.doom9.org/showthread.php?p=1548318#post1548318 cretindesalpes' function], you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling Show.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common values: ''blksize''/4 or ''blksize''/2. Larger ''overlap'' looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:''Truemotion'' is a preset of some MVAnalyze parameter values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|''blksize'' for SD, 0 for HD}}
{{Par|Vpad|int|''blksize'' for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on ''blksize'': 4{{=}}>100, 8{{=}}>400, 16{{=}}>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, try first the Str and Amp parameters.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for ''contrasharp'' to compare against; video resolution and properties must be the same (different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: '''Super''', '''bv1''', '''fv1''', '''bv2''', '''fv2''', '''bv3''', '''fv3''', '''bv4''', '''fv4''', '''bv6''', '''fv6''', '''vmulti'''.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. ''lsb_in''=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using ''Globals''=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with ''Str'' and ''Amp'' parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any MSuper(). Therefore if you are not processing chroma (''chroma''=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are unset. In this regard for previewing tasks with prefilterings -- or just the ''Str'' and ''Amp'' effect -- set ''chroma'' to true temporally or follow with ''GreyScale''(). For YUY2 sources set ''Planar2Interleaved''() after cropping for previewing.

'''SMDegrain''', the Simple MDegrain Mod, is mainly a convenience function for using [[MVTools]]. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original '''SMDegrain()''' by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) MDegrain denoising.
* '''Higher temporal radius''' (tr>3): The [[MVTools]] mod (and hence this script) also allows for hack-free higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A ''CClip'' parameter is also supplied so you can choose another source to sharpen from, other than the default '''SMDegrain()''' input.
* '''YUY2 support''': It automatically and fully supports YUY2.
* '''Interlaced support''': It supports interlaced sources with most parameters as well.
* '''Extended Subpixel Accuracy''': [[nnedi3]] is allowed as a subpixel filter, not necessary in most cases, but if you are quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where '''SMDegrain()''' couldn't find a matching block for denoising. One use for it would be spatial denoisers or deblockers since high-motion areas are prone to heavy blocking and artifacts.
* '''Global Motion Vector In/Out''': Reuse motion vectors globals for faster processing, or just use '''SMDegrain()''' as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): Slower, but sometimes a big quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for '''SMDegrain()''' being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see [http://forum.doom9.org/showthread.php?p=1544619#post1544619 this] and ''prefilter'' notes), but those are the rare cases.

To picture what the function does, a simple '''SMDegrain()''' call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (''Dither_Luma_Rebuild''(S0=1.0,c=0.0625) similar to ''color_yuv''(levels="TV->PC")) so you have more range to detect motion vectors, the ''rfilter''=4 for a bit more quality super search, the changed default of ''overlap'' from 0 to 4 and ''thSAD'' and ''thSADC'' from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for '''SMDegrain()'''.

==Using the filter==
*Input can be YV12 or YUY2, and '''must''' be TV range (which is normal). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary.
*Crop first (when not interlaced).
*Recommended to deblock if blocking is present, before crop (when cropping) and '''SMDegrain()'''. Or you can use ''prefilter''=3 which is also a good deblocker (dfttest) and let '''SMDegrain()''' clean the blocking for you.
*Default output mode(dithering) for ''lsb''=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use ''mode''=6 (error diffusion) or ''lsb_out''=true and keep filtering in 16bit
*Read the ''prefilter'' setting explanation for solutions to problematic sources

==Ready-to-run Samples==

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

A basic, fast, yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; ''pel''=1, ''hpad''=0, ''vpad''=0, ''blksize''=32, ''overlap''=16, ''truemotion''=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add ''truemotion''=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for ''contrasharp''.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

==Parameters==
{{FuncDef|SMDegrain}} (clip input, int "tr", int "thSAD", int "thSADC", bool "RefineMotion", val "contrasharp", clip "CClip", bool "interlaced", int "plane", int "Globals", int "pel", int "subpixel", val "prefilter", clip "mfilter", int "blksize", int "overlap", int "search", bool "truemotion", int "limit", int "limitc", int "thSCD1", int "thSCD2", bool "chroma", int "hpad", int "vpad", bool "lsb", bool "lsb_in", bool "lsb_out", int "mode", val "Show", float "Str", float "Amp")

===Basic===

{{ParR|tr|int|2|1-128}}
:Temporal radius, selects the MDegrain to use. This can be considered the strength of the denoising. Higher is generally better, but also much slower and each extra frame gives less improvement.
:tr 4+ requires Dither's MVTools2 mod. Max 64 for interlaced.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (''blksize''). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise ''blksize'', which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the "sharp" clip is the input, the "after" clip is the denoised clip. Alternately, a "before" clip can be specified with ''CClip'' (See Advanced).
:*True: use Didée's Contrasharpening() function (ContraHD() for HD) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:*An integer: LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.

{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a ''prefilter'' so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with ''lsb_out''=true then you will have to <tt>Weave().DitherPost(mode=6,interlaced=true)</tt> when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+.

{{Par|lsb_in|bool|False}}
:Set true if you use a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:Output to 16-bit instead of 8-bit. Use the helpers at the end of the SMDegrain() script to use Ditherpost() with YUY2 formats.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas. Automatically set if either ''lsb_in'' or ''lsb_out'' are enabled.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]] when ''lsb_out''=False, as a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default ''mode''=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use ''mode''=6 (error diffusion) if further processing will be done.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for ''pel''=2 or 4. This is the 'sharp' parameter in MSuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try ''prefilter''=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources ''prefilter''=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use ''lsb_in'', ''lsb_out'' according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in [http://forum.doom9.org/showthread.php?t=162813 Doom9] for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a ''prefilter'' as well. Or at last and the recommended solution, to use the built-in ''Str'' (strength) and ''Amp'' (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")
:Good resources for custom prefilters:

:*http://forum.doom9.org/showthread.php?t=132310
:*http://forum.doom9.org/showthread.php?t=133977
:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no ''thSAD'' tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), [http://forum.doom9.org/showthread.php?p=1544619#post1544619 Multilevel MDegrain], etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the ''prefilter'' clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Used when ''Str'' <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and ''Str'' are extrapolated arguments from [http://forum.doom9.org/showthread.php?p=1548318#post1548318 cretindesalpes' function], you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling Show.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common values: ''blksize''/4 or ''blksize''/2. Larger ''overlap'' looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:''Truemotion'' is a preset of some MVAnalyze parameter values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|''blksize'' for SD, 0 for HD}}
{{Par|Vpad|int|''blksize'' for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on ''blksize'': 4=>100, 8=>400, 16=>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, try first the Str and Amp parameters.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for ''contrasharp'' to compare against; video resolution and properties must be the same (different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: '''Super''', '''bv1''', '''fv1''', '''bv2''', '''fv2''', '''bv3''', '''fv3''', '''bv4''', '''fv4''', '''bv6''', '''fv6''', '''vmulti'''.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. ''lsb_in''=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using ''Globals''=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with ''Str'' and ''Amp'' parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any MSuper(). Therefore if you are not processing chroma (''chroma''=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are unset. In this regard for previewing tasks with prefilterings -- or just the ''Str'' and ''Amp'' effect -- set ''chroma'' to true temporally or follow with ''GreyScale''(). For YUY2 sources set ''Planar2Interleaved''() after cropping for previewing.

SMDegrain, the Simple MDegrain Mod, is mainly a convenience function for using MVTools. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original SMDegrain() by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) mdegrain denoising.
* '''Higher temporal radius''' (tr>3): As the above feature the mvtools2 mod allows (and hence this script) for real (no hacks) higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A CClip parameter is also supplied so you can choose another source to sharpen from, other than the default SMDegrain() input.
* '''YUY2 support''': It automatically supports YUY2 sources for all the given parameters.
* '''Interlaced support''': It supports interlaced sources, for YUY2 color spaces and most parameters as well.
* '''Extended Subpixel Accuracy''': nnedi3 is added as the 4th option for this setting, not strictly necessary in most cases, but if you are a quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where SMDegrain() couldn't find a matching block, or in other words motion areas where SMDegrain() couldn't denoise. One use for it would be spatial denoisers or deblockers since motion areas are prone to heavy blocking and artifacts.
* '''Motion Vectors Globals Input/Output''': Reuse motion vectors globals for faster processing, or just use SMDegrain() as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): If time is not an issue, you should use this one for a quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for SMDegrain() being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see this and prefilter notes), but those are the rare cases.

To picture what the function does, a simple SMDegrain() call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (Dither_Luma_Rebuild(S0=1.0,c=0.0625) similar to color_yuv(levels="TV->PC")) so you have more range to detect motion vectors, the rfilter=4 for a bit more quality super search, the changed default of overlap from 0 to 4 and thSAD and thSADC from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for SMDegrain().

==Using the filter==
*Input can be YV12 or YUY2 (interleaved YUY2 which is the common standard format)
*Input luma must NOT be PC range (sources normally are in TV range). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary
*Crop if necessary before SMDegrain() (when not interlaced)
*Recommended to deblock if blocking is present, before crop (when cropping) and SMDegrain(). Or you can use prefilter=3 which is also a good deblocker (dfttest) and let SMDegrain() clean the blocking for you
*Default output mode(dithering) for lsb=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use mode=6 (error diffusion) or lsb_out=true and keep filtering in 16bit
*Read the prefilter setting explanation for solutions to problematic sources

==Ready-to-run Samples==

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

A basic, fast, yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; pel=1, hpad=0, vpad=0, blksize=32, overlap=16, truemotion=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add truemotion=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for the contrasharpening process.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

==Parameters==
{{FuncDef|SMDegrain}} (clip input, int "tr", int "thSAD", int "thSADC", bool "RefineMotion", val "contrasharp", clip "CClip", bool "interlaced", int "plane", int "Globals", int "pel", int "subpixel", val "prefilter", clip "mfilter", int "blksize", int "overlap", int "search", bool "truemotion", int "limit", int "limitc", int "thSCD1", int "thSCD2", bool "chroma", int "hpad", int "vpad", bool "lsb", bool "lsb_in", bool "lsb_out", int "mode", val "Show", float "Str", float "Amp")

===Basic===

{{ParR|tr|int|2|1+}}
:Temporal radius. This can be considered the strength of the denoising. Select between MDegrain 1, 2, 3, 4, 5, 6 or higher. Higher is generally better, but also much slower and improvements get less drastic.
:tr 4+ (limit is tr=128, 64 for interlaced) requires Dither's MVTools2 mod.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the next formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (blksize). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise the block size (blksize), which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the before "sharp" clip is the one used as input for SMDegrain(), the "after" clip is the denoised clip. Independently a "before" clip can be specified with the CClip parameter (See Advanced)
:Contrasharp when set to "true", will use Didée's Contrasharpening() function (or the modded version ContraHD() for HD sources) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:If you set an integer, LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.
{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a prefilter so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with lsb_out=true then you will have to add Weave().DitherPost(mode=6,interlaced=true) when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas.

{{Par|lsb_in|bool|False}}
:Set it to true if you use SMDegrain() in a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:If you set lsb to true, you can also choose to output in 16 bits (an internal 32 bit->16 bit conversion is done) so you can keep filtering in 16 bits and/or use your own Ditherpost().
:Use the helpers at the end of the SMDegrain() script to make Ditherpost() able to use when dealing with YUY2 formats.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]]. If you process in 32bit and lsb_out (16bit output) is not enabled, a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default mode=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use mode=6 (error diffusion) if further processing is needed.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for pel=2 or 4. This is the 'sharp' parameter in msuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try prefilter=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources prefilter=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use lsb_in, lsb_out according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in Doom9 for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a prefilter as well. Or at last and the recommended solution, to use the built-in Str (strength) and Amp (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")
:Good resources for custom prefilters:

:*http://forum.doom9.org/showthread.php?t=133977
:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no thSAD tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), Multilevel mdegrain, etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the prefilter clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Uses when Str <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and the Str parameters are extrapolated arguments of a cretindesalpes' function, you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling Show.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common overlap values: blksize/4 or blksize/2. Larger overlap looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:Truemotion is a preset of some parameters values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|blksize for SD, 0 for HD}}
{{Par|Vpad|int|blksize for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on blocksize: 4=>100, 8=>400, 16=>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, try first the Str and Amp parameters.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for contrasharpening to compare against; video resolution and properties must be the same (except different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: Super, bv1, fv1, bv2, fv2, bv3, fv3, bv4, fv4, bv6, fv6, vmulti.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. lsb_in=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using Globals=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with Str and Amp parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any msuper(). Therefore if you are not processing chroma for motion analysis(chroma=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are set to a value of 0 which is a dummy value meaning nothing or "discard". In this regard for previewing tasks with prefilterings or just the Str and Amp effect simply set chroma to true temporally. For YUY2 sources set Planar2Interleaved() after cropping for previewing.

SMDegrain, the Simple MDegrain Mod, is mainly a convenience function for using MVTools. It is not a magic function (the magic comes from mvtools), it just takes the repetitive code blocks needed for mvtools+mdegrain denoising and wraps them into this function.

It has internal switches for interlaced or YUY2 content, saving you from writing long lines of code and preventing from possible mistakes. YUY2 is even automatically detected. Apart of that it adds some small and simple enhancements listed below, like easy prefilters, slightly better motion vectors (thanks to an internal TV->PC luma expansion and the possibility of dark enhancement), easy nnedi3 subpixel accuracy, globals import/export, show panel, and contra-sharpening option.

==Dependencies==
[[MaskTools2]] and [[MVTools]] (mod versions recommended)

===Optional===
* [[Dither]] for 16 bit processing (v1.26.5 or higher)
* [[RgTools]] for contrasharp=true or prefilter=1 or 2
* [[LSFmod]] for contrasharp > 0.0
* [[dfttest]] for prefilter=3
* [[nnedi3]] for subpixel=3
''Beware, tp7's plugin mods have no YUY2 support, require AviSynth 2.6a5 or latest Set's MT for v2.6, and Visual C++ 2012 Redistributable.''

==Aknowledgements==
Original SMDegrain() by Caroliano

This function uses code from Didée, and cretindesalpes' creations, and has parts inspired by LaTo's functions (old readme, Show panel, etc) and Jawed's Killer() function, apart of relying on third-party tools for certain features.

Special thanks go to: cretindesalpes, Didée, Gavino, Sagekilla, and MVtools people.

==Introduction==
The benefit of using SMDegrain over directly calling MDegrain is:
* '''High bitdepth denoising''': This is the first wrapper function to support 32bit (16bit pipeline) mdegrain denoising.
* '''Higher temporal radius''' (tr>3): As the above feature the mvtools2 mod allows (and hence this script) for real (no hacks) higher temporal radius.
* '''Contrasharpening''': The pretty much standarized sharpening method created by Didée is blended into the function, so you can easily use it in 16bit pipelines. An strength biased method is also possible. A CClip parameter is also supplied so you can choose another source to sharpen from, other than the default SMDegrain() input.
* '''YUY2 support''': It automatically supports YUY2 sources for all the given parameters.
* '''Interlaced support''': It supports interlaced sources, for YUY2 color spaces and most parameters as well.
* '''Extended Subpixel Accuracy''': nnedi3 is added as the 4th option for this setting, not strictly necessary in most cases, but if you are a quality mad try to set it on.
* '''Better Motion Vectors''': An internal conversion from TV levels (reduced values range) to PC levels (extended values range) is done to the clip the motion analysis will be performed on, so you can get better motion vectors (up to 16%)
* '''Prefilters''': An easy parameter to load generalist prefilters that perform well in most situations. It also accepts loading your personal prefiltered clips.
* '''Motion Filters''': New in version 3.0d. It will allow you to filter those parts where SMDegrain() couldn't find a matching block, or in other words motion areas where SMDegrain() couldn't denoise. One use for it would be spatial denoisers or deblockers since motion areas are prone to heavy blocking and artifacts.
* '''Motion Vectors Globals Input/Output''': Reuse motion vectors globals for faster processing, or just use SMDegrain() as a shortcut for creating nice quality motion vectors.
* '''RefineMotion Option''' (MRecalculate): If time is not an issue, you should use this one for a quality boost.
* '''Show Panel''': Everything is off by default, but some settings change in context. Check what is happening behind the scenes and have a fast look at all your settings.
* '''Robust''': Everything of the above works with each other no problem (interoperability), also in the process some error proof, bugfixes and bug workarounds were implemented or at least warned so you know that most of what is done is reliable, bugs free and optimized. The general idea is to serve as an user friendly front end for vanilla mvtools2+mdegrain or as the original script creator entitled "To make your scripts shorter and less geeky". Most parameters are turned off or defaulted to mvtools2 defaults and features are based on popular general conceived procedures.

Parameters are arranged in 3 blocks.
*'''Basic''': For people who just need the most basic parameters because either they don't have the time, knowledge or interest into looking for complex settings. Or they are content with defaults (pretty much mvtools defaults)
*'''High Bit Depth''': There's not much to think about this. This just enables (default is disabled), high bit depth denoising. That is, more quality, but also needs more processing power hence slower.
*'''Advanced''': If you run into some problems, are nitpicking or just want to fine tune your settings according to the source, have a look at this block, it contains the rest and bulk of the function parameters.

Temporal denoising is a widespread procedure for noise cleaning in most type of video sources. The only limitation for SMDegrain() being when there are (very) high levels of grain, in which case you would need to rely on more "creative" and source centric solutions (see this and prefilter notes), but those are the rare cases.

To picture what the function does, a simple SMDegrain() call matches the next code (for SD resolutions):

super_search = Dither_Luma_Rebuild(S0=1.0,c=0.0625).MSuper(rfilter=4)

bv2 = super_search.MAnalyse(isb = true, delta = 2, overlap= 4)
bv1 = super_search.MAnalyse(isb = true, delta = 1, overlap= 4)
fv1 = super_search.MAnalyse(isb = false, delta = 1, overlap= 4)
fv2 = super_search.MAnalyse(isb = false, delta = 2, overlap= 4)

MDegrain2(MSuper(levels=1), bv1, fv1, bv2, fv2, thSAD=300, thSADC=150)

As you see no wizardry. The only changes made are the TV->PC luma expansion (Dither_Luma_Rebuild(S0=1.0,c=0.0625) similar to color_yuv(levels="TV->PC")) so you have more range to detect motion vectors, the rfilter=4 for a bit more quality super search, the changed default of overlap from 0 to 4 and thSAD and thSADC from 400 to 300 and 150 respectively for safer results. Nothing else. The problem is that as soon you want to change a little thing like say temporal radius it requires you to edit in more than a few places, so this is very annoying and so forth the main reason for SMDegrain().

==Quick Workflow Guide==
*Input can be YV12 or YUY2 (interleaved YUY2 which is the common standard format)
*Input luma must NOT be PC range (sources normally are in TV range). It's also recommended to be in modulus 16 size (resolution multiple of 16), although not strictly necessary
*Crop if necessary before SMDegrain() (when not interlaced)
*Recommended to deblock if blocking is present, before crop (when cropping) and SMDegrain(). Or you can use prefilter=3 which is also a good deblocker (dfttest) and let SMDegrain() clean the blocking for you
*Default output mode(dithering) for lsb=true (when non interlaced) is ordered dither (optimized for encoding), so it is not recommended to keep filtering non-edge areas of your source, you can instead use mode=6 (error diffusion) or lsb_out=true and keep filtering in 16bit
*Read the prefilter setting explanation for solutions to problematic sources

I consider this a good starting point where to start tweaking, whether be it for quality or speed:
SMDegrain(tr=2,thSAD=250,contrasharp=true,refinemotion=true,lsb=true)

==Parameters==
{{FuncDef|SMDegrain}} (clip input, int "tr", int "thSAD", int "thSADC", bool "RefineMotion", val "contrasharp", clip "CClip", bool "interlaced", int "plane", int "Globals", int "pel", int "subpixel", val "prefilter", clip "mfilter", int "blksize", int "overlap", int "search", bool "truemotion", int "limit", int "limitc", int "thSCD1", int "thSCD2", bool "chroma", int "hpad", int "vpad", bool "lsb", bool "lsb_in", bool "lsb_out", int "mode", val "Show", float "Str", float "Amp")

===Basic===

{{ParR|tr|int|2|1+}}
:Temporal radius. This can be considered the strength of the denoising. Select between MDegrain 1, 2, 3, 4, 5, 6 or higher. Higher is generally better, but also much slower and improvements get less drastic.
:tr 4+ (limit is tr=128, 64 for interlaced) requires Dither's MVTools2 mod.

{{Par|thSAD|int|300}}
{{Par|thSADC|int|150}}
:"Sum of Absolute Differences" threshold. This is the spatial difference threshold where the motion search will consider whether to denoise given the next formula:
::Denoise_Weight = max( 0, 1 - 2*blockSAD² / (thSAD² + blockSAD²) )
:This spatial difference will be compared in blocks (blksize). If your noise is not getting into consideration for the denoising try raising this value, or reduce its SAD with previous prefiltering. You can alternatively raise the block size (blksize), which will likely even blocks SAD. Low values can result in staggered/blotchy denoising, large values can result in ghosting and artifacts. Values in the range 200~600 are usual.
:thSADC is the same logic applied to chroma planes, since there are less differences on the chroma planes it uses by default thSAD/2 for safer chroma results.
:'''Recommendation''': Use slightly greater values than you are used to in other mdegrain based functions since the internal clip for the motion search in SMDegrain() has the contrast increased.

{{ParR|Contrasharp|bool|False|True/False}}
{{ParR|Contrasharp|int|-|0-100}}
:Contrasharpening is a technique that compares the differences between the clip before blurring (original) and after blurring (filtered), and sharpens locally with consequent strength. By default the before "sharp" clip is the one used as input for SMDegrain(), the "after" clip is the denoised clip. Independently a "before" clip can be specified with the CClip parameter (See Advanced)
:Contrasharp when set to "true", will use Didée's Contrasharpening() function (or the modded version ContraHD() for HD sources) which "Sharpens the denoised clip, but doesn't add more to any pixel than what was removed previously." In the practice you will get a slightly sharper result than the source, which is welcome.
:If you set an integer, LSFmod() will be used instead. It will be much slower, but maybe better for certain sources. Its value will serve as a contrasharpening multiplier, use one around 50 for similar strength as Contrasharpening(). LSFmod is less-suitable for HD sources.
{{Par|RefineMotion|bool|False}}
:Refines and recalculates motion data of previously estimated (by MAnalyse) motion vectors. Turn it on for better motion vectors, specially when dealing with ghosting issues, small details or lineart fading and whatnot.
:'''Caution''': It won't help much if you use a prefilter so strong that blurs too much or kills all the details you are aiming to protect in first place.

{{ParR|plane|int|4|0-4}}
:Select the planes you wish to process:
:*0: luma only
:*1: chroma U
:*2: chroma V
:*3: both chromas
:*4: all (Default)
:'''Caution''': plane=1-4 can sometimes create chroma smearing. In such case I recommend denoising chroma planes in the spatial domain.

{{Par|Interlaced|bool|False}}
:If you want to denoise an interlaced source set this parameter to true. Output will also be interlaced. If you pair this with lsb_out=true then you will have to add Weave().DitherPost(mode=6,interlaced=true) when converting back to 8 bit.

===High Bit Depth Processing And Dithering===
All High Bit Depth parameters require [[Dither]] and [[MVTools]] 2.6+.

{{Par|lsb|bool|False}}
:This enables 32 bit depth precision for denoising. You gain extra denoising accuracy, most noticeable in the prevention of banding in flat areas.

{{Par|lsb_in|bool|False}}
:Set it to true if you use SMDegrain() in a 16 bits filter chain. *(EXPERIMENTAL, use under test environment)

{{Par|lsb_out|bool|False}}
:If you set lsb to true, you can also choose to output in 16 bits (an internal 32 bit->16 bit conversion is done) so you can keep filtering in 16 bits and/or use your own Ditherpost().
:Use the helpers at the end of the SMDegrain() script to make Ditherpost() able to use when dealing with YUY2 formats.

{{ParR|mode|int|0|-1-8}}
:This is the '''mode''' of [[Dither#DitherPost|DitherPost]]. If you process in 32bit and lsb_out (16bit output) is not enabled, a dithering method must be chosen for the 32bit->8bit conversion. (Interlaced content is locked to mode=6) The default mode=0 will help you optimize the dithering for optimum encodings when no further non-edge processing is done. Use mode=6 (error diffusion) if further processing is needed.

===Advanced===

{{ParR|pel|int|2|1,2,4}}
:Accuracy of the motion estimation:
:* 1: full-pixel (Default for HD)
:* 2: half-pixel (Default for SD)
:* 4: quarter-pixel (often more accurate, but much slower and not always better)

{{ParR|subpixel|int|2|0-3}}
:Subpixel interpolation method for pel=2 or 4. This is the 'sharp' parameter in msuper(), although it isn't related to output sharpness but better accuracy for the motion estimation.
:* 0: bilinear (softest)
:* 1: bicubic (4 tap Catmull-Rom)
:* 2: sharper Wiener (6 tap, similar to Lanczos) (Default)
:* 3: [[nnedi3]] (very high quality: useful for small sources but usually overkill. requires plugin)

{{ParR|prefilter|int|-1|-1-3}}
{{Par|prefilter|clip|None}}
:* -1: off (Default)
:* 0: light controlled gauss blur
:* 1: mild median/gauss blur
:* 2: strong median/gauss blur
:* 3: [[dfttest]] (spatial)
:* clip: supply your own
:Denoises a version of the clip that will be used to obtain the motion vectors. Useful for very damaged/grainy sources, this will help to get better motion vectors.
:For sources with Gibbs noise, especially on anime, try prefilter=1 or 2 or better yet strong median filters (through clip input) in order to soothe the high SAD of sharp edges. For blocky sources, or a general more quality/safer prefilter use option 3 (dfttest)
:By default dfttest outputs a sstring txt file to your script folder, you can delete it. This doesn't happen when using the modded dfttest (version 1.9.2 or higher) of the Dither tools.
:For HD sources prefilter=2 makes more sense than 1, because it uses a wider denoising window.
:If instead you want to use your own prefilter denoiser, just define it in a variable and reference it here. Remember to:
:*Feed always 8 bit clips.
:*Input in fields for interlaced content *(read below)
:*Feed here planar ( by using Interleaved2Planar() ) YUY2 clips (not interleaved) when working with YUY2 sources.
:You will likely want to use spatial denoisers like median filters (removegrain=17, medianblur, etc). For very grainy or fizz grain noise you can try prefiltering in temporal or if this is not enough, try adding a new SMDegrain() line again but without globals. Use lsb_in, lsb_out according so results are smooth. You can even use SMDegrain() as a prefilter for SMDegrain() in very temporal unstable sources.
:Another trick for fizz grain is to serve a prefiltered clip where bright values are more denoised than dark values, you can do this through luma masks with masktools2 code. Search in Doom9 for reference.
:For interlaced sources remember:
::Spatial filtering: pre=separatefields().spatial_prefilters_here()
::Temporal filtering: pre=separatefields().interleave(selecteven().temporal_filters(),selectodd().temporal_filters())
:SMDegrain() (and MDegrain) is likely to produce blending artifacts or oversmooth in dark areas specially on cartoons, to tackle this see RefineMotion or expand the luma range in the darks. For this there are many options, you can use your preferred gamma enhancer and input it as the prefilter, or use the examples below for linear brightening (masktools2) and input it as a prefilter as well. Or at last and the recommended solution, to use the built-in Str (strength) and Amp (amplitude) parameters for a curve type dark enhancement, check the effects by enabling Show and changing your previewing conditions to PC levels.
:For brightening dark values linearly (brighter parts less brightening)
str=1
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ x 1 - abs +")
:Or for a more contrasty image (although not as much dark enhancing - not linear)
str=40
mt_lut("x x "+string(str)+" 6 * - 255 - abs 255 / ^ "+string(str)+" / x 1 - abs +")

:Notes: To sum it up; generally in denoising, temporal filters are always preferred due to its natural look (versus spatial filters). But more often than not for good results prefiltering plays a key role on the output quality, and setting it up nicely can be looked as an art by itself.
:If there's a reached point where no prefiltering, no thSAD tweaking, etc, makes able to denoise a certain motion part/area/scene, then this is due to the motion vectors preventing them from being "denoised" (also read "artifacted"), in which case you will need to rely on alternative solutions (motion compensation, filters like MCTemporalDenoise(), TemporalDegrain(), Multilevel mdegrain, etc) or just use plain spatial filters with motion masks. Creating these discerning masks for static and motion scenes and combining them is a research task on the end user side.

{{Par|mfilter|clip|None}}
:Motion Filter, an optional user-supplied clip that will be passed through those areas where SMDegrain() couldn't find a matching block, normally high motion areas. One use for it would be to to use spatial filters, like deblockers or blurring filters that mimic motion blur.

{{ParR|Str|float|1.0|0.0-8.0}}
:Gamma correction. With this parameter you control the strength of the brightening of the prefilter clip, good for when problems with dark areas arise. Using this internally instead of externally creates less quantization artifacts, since it's done in the same stage as the TV->PC range conversion.

{{ParR|Amp|float|0.0625|0.0-1.0}}
:Uses when Str <> 1.0. This defines the amplitude of the brightening in the luma range, for example by using 1.0 all the luma range will be used and the brightening will find its peak at luma value 128 in the original. Default is 0.0625 (1.0/16) which just sits over luma value 16 (256/16) This and the Str parameters are extrapolated arguments of a cretindesalpes' function, you can find a graph and more insight explanations at the original post.
:Check these 2 parameters effects by enabling Show.

{{ParR|blksize|int|8 for SD, 16 for HD|4,8,16}}
:Size of a block (horizontal x vertical). Larger blocks are faster and less sensitive to noise, but also less accurate.

{{Par|overlap|int|blksize/2}}
:Must be *even* and *less* than block size. Common overlap values: blksize/4 or blksize/2. Larger overlap looks slightly better and runs slower.

{{ParR|Search|int|4|0-7}}
:This is the '''search''' of [[MVTools/MAnalyze|MAnalyze]].

{{Par|Truemotion|bool|True for SD, False for HD}}
:Truemotion is a preset of some parameters values. It allows easy to switch default values of all "true motion" parameters at once. Set it 'true' for true motion search (high vector coherence), set it 'false' to search motion vectors with best SAD. Truemotion is slower and may blur textures and thin details more, but will usually remove more noise.
:For HD sources where the main problems are just excessive grain, I have defaulted it to false, this is not only faster but honors detail accuracy (the main existing point for HD sources) and overall object shading.

{{Par|Chroma|bool|True}}
:Set false to totally ignore chroma for finding motion vectors, for more speed with little cost in quality or when your chroma is too bad to find good matches. Don't process chroma planes without chroma vectors, MVTools doesn't seem to work right.

{{Par|Hpad|int|blksize for SD, 0 for HD}}
{{Par|Vpad|int|blksize for SD, 0 for HD}}
:Horizontal/vertical padding added to source frame (left, right, top, and bottom) for better motion estimation near borders.
:Try to have clean borders in your source (no NAB/black borders) to start with before tweaking this setting. If necessary, crop beforehand ideally in multiples of 16. Turn it to 0 if you are running out of memory.

{{Par|thSCD1|int|based on blocksize: 4=>100, 8=>400, 16=>1600}}
:Threshold which decides whether a block has changed between the previous frame and the current one, used to tweak the scene change detection. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. To fix blending on scene changes on dark scenes, try first the Str and Amp parameters.

{{ParR|thSCD2|int|130|0-250}}
:Threshold which sets how many blocks have to change for the frame to be considered as a scene change.

{{ParR|limit|int|255|1-255}}
{{ParR|limitC|int|255|1-255}}
:Maximal change of pixel luma/chroma, to prevent some artifacts.

{{Par|CClip|clip|None}}
:Optional sharp version for contrasharpening to compare against; video resolution and properties must be the same (except different bit depth is OK). Using this option defaults ''contrasharp'' to True.

{{ParR|Globals|int|0|0-3}}
:With this parameter you can create or load pre-processed motion vectors, to save doing the work for multiple SMDegrain calls.
:*0: Ignore globals, just process
:*1: Read globals and Process
:*2: Process and output globals
:*3: Output globals only, don't process
:Some parameters '''MUST MATCH''' between output and input stages: ''pel'', ''subpixel'', ''chroma'', and ''vpad''/''hpad'' cannot change. When reading (Globals=1) only some parameters work: ''tr'', ''thSAD'', ''plane'', ''limit'', ''limitc'', ''contrasharp'', ''CClip'', ''interlaced'' and the ''lsb'' parameters. Others are ignored.
:Global names that can be reused are: Super, bv1, fv1, bv2, fv2, bv3, fv3, bv4, fv4, bv6, fv6, vmulti.
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
SMDegrain(tr=3,thSAD=400,globals=1) # You can use a lower "tr" or "thSAD" if you want
:or
SMDegrain(tr=3,thSAD=400,globals=3) # Outputs vectors
Super = MSuper(levels=1) # Add this line just before if you have some processing between Globals Output and Input.
MDegrain3(Super, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=400)

{{Par|Show|bool|False}}
{{ParR|Show|str|-|"Speed", "Memory", "Quality"}}
:This will show the prefiltered clip to be used for the motion search to the left(<--), and the used parameters list to the right (-->)
:If the parameters panel is broken i.e. overlapping lines, hidden lines, etc, most likely your settings are wrong, (e.g. lsb_in=true when input is 8bit) so it will also work well as a debug function. If you set Show to a string as indicated above, related parameters will be highlighted to guide you on correctly tweaking the function. This is loosely based, so it doesn't exclude you from reading carefully every parameter explanation.
:Even when you are not using any prefiltering, the clip to be used for the motion search where you obtain the motion vectors, will be converted from TV levels to PC levels, the only exception being when using Globals=1 (Read) in which case the "prefiltered" clip will be exactly the same as input clip (that is no luma conversion, although constrained to 8 bit). Additionally you can tweak the dark expansion with Str and Amp parameters and check the effects in the left panel, but be aware to change your viewing conditions as it is in PC levels.
:The left panel preserves its properties so you can crop out the right panel and use it as a prefilter clip of any msuper(). Therefore if you are not processing chroma for motion analysis(chroma=false) the prefiltered clip will be green, don't panic, this is correct, this happens when the U and V planes are set to a value of 0 which is a dummy value meaning nothing or "discard". In this regard for previewing tasks with prefilterings or just the Str and Amp effect simply set chroma to true temporally. For YUY2 sources set Planar2Interleaved() after cropping for previewing.

==Final Notes==
If there is an important parameter not implemented, you have any issue or found a bug, please don't hesitate and ask in its [http://forum.videohelp.com/threads/369142 VideoHelp thread].

==Example Scripts==

A basic yet very functional call for light grain (mvtools2+masktools2 only needed)
SMDegrain(tr=1,thSAD=300,contrasharp=true)

A typical more worked call compatible with official mvtools2 (mvtools2+masktools2 only needed)
SMDegrain(tr=2,thSAD=300,interlaced=true,prefilter=1,contrasharp=true)

Good compromise between speed and quality (denoising with high precision)
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true)

Similar to the previous example, the next is a personal preference. Turned all chroma off for safeness (chroma is rarely temporal-reliable enough) and speed.
SMDegrain(tr=2,thSAD=300,contrasharp=true,refinemotion=true,lsb=true,chroma=false,plane=0)

This is a good example to show that interlaced YUY2 sources can be processed seamlessly.
# mod4 (modulus 4) interlaced YUY2 source
SMDegrain(tr=1,thSAD=250,interlaced=true,contrasharp=true,lsb=true)

HD sources are detected automatically, and as so settings are optimized for speed; pel=1, hpad=0, vpad=0, blksize=32, overlap=16, truemotion=false
# HD source (from 1100px wide or 600px high up)
SMDegrain(tr=2,thSAD=180,prefilter=2,contrasharp=30,refinemotion=true,lsb=true,chroma=false,plane=0)

For dealing with dark scenes (you could also add truemotion=false)
SMDegrain(tr=3,thSAD=300,contrasharp=true,str=2.0,refinemotion=true,lsb=true)

Tackling a grainy source:
pre=fluxsmootht(3).removegrain(11)
SMDegrain(tr=6,thSAD=500,contrasharp=30,prefilter=pre,str=1.2,refinemotion=true,lsb=true)

Here 2 things are shown; how to work on a 16bit pipeline, and reference a prior state of the script for the contrasharpening process.
sharp=last
dfttest(tbsize=1,sigma=10,lsb=true)

SMDegrain(tr=3,thSAD=300,CClip=sharp,lsb_in=true,lsb_out=true)

LinearResize(854,480,lsb_in=true, mode=0)

(Re)using motion vectors globals
SMDegrain(tr=1,thSAD=400,prefilter=3,str=1.4,globals=3) # Output vectors only
MFlowFps(Super, bv1, fv1, num=60,den=1)

== About MVTools ==
MVTools plugin for AviSynth 2.5 is a collection of functions for estimation and compensation of objects motion in video clips. Motion compensation may be used for strong temporal denoising, advanced framerate conversions, image restoration and other tasks.

The plugin contains the motion estimation server-function MAnalyse to find the motion vectors and several motion compensation client-functions (MCompensate, MMask and others) which use these vectors.

Plugin uses block-matching method of motion estimation (similar methods are used in MPEG2, MPEG4, etc). At analysis stage plugin divides frames by small blocks and try to find for every block in current frame the most similar (matching) block in second frame (previous or next). The relative shift of these blocks is motion vector. The main measure of block similarity is sum of absolute differences (SAD) of all pixels of these two blocks compared. SAD is a value which says how good the motion estimation was.

The output of MAnalyse (server) is special clip with motion vector information in some format.

At compensation stage the plugin client functions read the motion vectors and use them to move blocks and form motion compensated frame (or realize some other full or partial motion compensation or interpolation function). Every object (block) in this (fully) compensated frame is placed in the same position as this object in current frame. So, we may (for example) use strong temporal denoising even for quite fast moving objects without producing annoying artifacts and ghosting (object's features and edges are coincide if compensation is perfect). Plugin can create compensated neighbor frames for every current frame, and denoise it by internal function. Alternatively, you can use compensated and original frames to create interleaved clip, denoise it by any external temporal filter, and select central cleaned original frames for output (see examples).

Of course, the motion estimation and compensation is not ideal and precise. In some complex cases (video with fading, ultra-fast motion, or periodic structures) the motion estimation may be completely wrong, and compensated frame will be blocky and (or) ugly. Severe difficulty is also due to objects mutual screening (occlusion) or reverse opening. Complex Avisynth scripts with many motion compensation functions may eat huge amount of memory and result in very slow processing. It is not simple but quite advanced plugin. Use it for appropriate cases only, and try to tune its parameters. There are many discussions about motion compensation using at doom9 Avisynth forum. In particular see [http://forum.doom9.org/showthread.php?t=76041 old MVTools thread], [http://forum.doom9.org/showthread.php?t=102071 true motion thread], [http://forum.doom9.org/showthread.php?t=84770 new MVTools thread] and some other. Try to read the postings in addition to this documentation and ask for support there. If you really interested in motion estimation and compensation topics, you can easy find numerous scientific publications (use WWW search).

Notes: The plugin is still under development. Current version has some limitations. Only progressive YV12, YUY2 video is supported. Use color format conversion and try use (smart) bob-deinterlace for interlaced video (SeparateFields may works too with or without SelectEven/SelectOdd). Some complex scripts (MVBOB, MCBOB, TempGaussMC) use MVTools for motion compensated deinterlace.
Alternatively you can try to use Motion plugin by mg262.

'''Official documentation: http://avisynth.org.ru/mvtools/mvtools2.html'''

== Common parameters ==
Filters that use motion vectors have common parameters. Those are the scene-change detection thresholds, and the isse mmx flag. They also use one or several vectors stream, which are produced by MAnalyse.

*{{Template:FuncDef2|thSCD1}} (int): threshold which decides whether a block has changed between the previous frame and the current one. When a block has changed, it means that motion estimation for it isn't relevant. It occurs for example at scene changes. So it is one of the thresholds used to tweak the scene changes detection engine. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. The threshold is compared to the SAD (Sum of Absolute Differences, a value which says how bad the motion estimation was ) value. For exactly identical blocks we have SAD=0. But real blocks are always different because of objects complex movement (zoom, rotation, deformation), discrete pixels sampling, and noise. Suppose we have two compared 8x8 blocks with every pixel different by 5. It this case SAD will be 8x8x5 = 320 (block will not detected as changed for thSCD1=400). If you use 4x4 blocks, SAD will be 320/4. If you use 16x16 blocks, SAD will be 320*4. Really this parameter is scaled internally in MVTools, and you must always use reduced to block size 8x8 value. Default is 400 (since v.1.4.1).

*{{Template:FuncDef2|thSCD2}} (int): threshold which sets how many blocks have to change for the frame to be considered as a scene change. It is ranged from 0 to 255, 0 meaning 0 %, 255 meaning 100 %. Default is 130 ( which means 51 % ).

*{{Template:FuncDef2|isse}} (int): flag which allows to enable (if set to True) or disable (if set to False) ISSE, MMX and other CPU optimizations (for debugging). Default is True. If your processor doesn't support CPU optimizations, it will be disabled anyway ( and you won't be able to activate them ).

*{{Template:FuncDef2|planar}} (bool): flag to use special planar color format for YUY2 clips both for input and output of function. It uses special trick for storing of frames with planar color data organization (separate Y, U, V planes in memory) in normal interleaved YUY2 frames format as a container. This way we can avoid numerous internal interleaved to planar conversions and increase speed. You can convert normal interleaved YUY2 source clip to planar format with Interleaved2planar function from RemoveGrain plugin by kassandro, and convert final result by Planar2interleaved function. This special planar YUY2 format is also supported by Removegrain plugin by Kassandro, MaskTools2 plugin by Manao and some others. This trick will not be needed in Avisynth v2.6 with native support of planar YV16 format. This parameter is ignored for YV12 clips. Note: super clip is always planar. Default is planar=false.

== Description ==
DctFiler is an experimental filter that, for each 8x8 block, will do a [http://en.wikipedia.org/wiki/Discrete_cosine_transform Discrete Cosine Transform] (DCT), scale down the selected frequency values, and then reverse the process with an Inverse Discrete Cosine Transform (IDCT).
 
 

== Requirements ==
* AviSynth 2.5.8 or [http://forum.doom9.org/showthread.php?t=168764 greater]
* Supported color formats: [[YUY2]], [[YV12]]
* Width and height need to be a multiple of 16 (mod16)

* [[MMX]], [[ISSE]] or [[SSE2]] capable CPU
 
== Known Issues ==
* [http://forum.doom9.org/showthread.php?p=1191185#post1191185 Stripe bug] - both variants are buggy at calculating DC, additional information [http://forum.doom9.org/showthread.php?p=1346201#post1346201 here] and [http://forum.doom9.org/showthread.php?p=1051452#post1051452 here].
 
== [[Script variables|Syntax and Parameters]] ==
 
=== DctFilter ===
For each 8x8 block it will do a Discrete Cosine Transform (DCT), scale down the selected frequency values, and then reverse the process with an Inverse Discrete Cosine Transform (IDCT). 
In the following example the highest frequency components in each row and column will be zeroed while the 2nd highest would be cut in half.
:<code>DctFilter(1,1,1,1,1,1,.5,0)</code>
The row & column parameters are multiplied together to get the scale factor for each of the 64 values in a block. So if the top left value was V[0,0] then in the example above the we would scale row 6, col 6 (V[6,6]) by .5 * .5 = .25. 
Note that while they look like floating point parameters above they really now only
have 3 bit accuracy so the only actual values used are 0, {{Frac|1|8}}, {{Frac|1|4}}, {{Frac|3|8}} ... 1.0. But you can specify any value and it will be rounded to the nearest one.
 
 
:{{Template:FuncDef|DctFilter (clip, float, float, float, float, float, float, float, float, int "chroma", int "fdct", int "idct", int "offx", int "offy")}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2| |float| }}
:::There are 8 positional floating point parameters, all of which must be specified as in the range (0.0 <= x <= 1.0). These correspond to scaling factors for the 8 rows and columns of the 8x8 DCT blocks.
:::The leftmost parameter corresponds to the top row, left column. This would be the DC component of the transform and should always be left as 1.0.

::{{Par2|chroma|int|1}}
:::Chroma processing:
::::*0 : do not process nor copy, output will be trash
::::*1 : process

::{{Par2|fdct|int|-1}}
::{{Par2|idct|int|-1}}
:::Choose which DCT to use (if you want to compare). Do not use fdct=2 or idct=3, it may crash!

::::*-1 : default
::::*0 : integer (does not work correctly)
::::*1 : [[MMX]]
::::*2 : [[iSSE]]
::::*3 : [[SSE2]]

::{{Par2|offx|int|0}}
::{{Par2|offy|int|0}}
:::Specify offsets, only use when the input clip's dimensions are mod16, otherwise it may crash.
 
::'''Note:''' the first 9 parameters are unnamed and do not have a default so they must be specified. The last 5 parameters are only available in <tt>DctFilter v0.0.1.5</tt>, consider them as experimental so use with caution (except for chroma).
 
-------------
 

=== DctFilterD ===
DctFilterD works similar to DctFilter but will zero out DiagCt number of the lower right diagonals of the DCT, leaving other values unchanged. 
In an 8x8 DCT result matrix there are 15 possible diagonals (visualize a chess board), so if you specify <code>DctFilterD(4)</code> then the 4 diagonals in the lower right corner of the DCT result will be set to 0. I haven't tested this much but, like my results with custom quant tables, it appears if you set DiagCt very large you will start to get edge noise, something like ringing.[http://forum.doom9.org/showpost.php?p=266216&postcount=145]
 
 
:{{Template:FuncDef|DctFilterD (clip, int)}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2| |int| }}
:::<tt>'''DiagCt'''</tt>: must be an integer from 1-14 saying how many of these diagonals must be zeroed, starting from the lower right hand corner.

:::'''Note:''' all parameters are unnamed and do not have a default so they must be specified.
 
-------------
 
=== DctAddConstant ===
Not much is known about this filter...
 
 
:{{Template:FuncDef|DctAddConstant (clip, float, float, float, float)}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2| |float| }}
::{{Par2| |float| }}
::{{Par2| |float| }}
::{{Par2| |float| }}

:::'''Note:''' all parameters are unnamed and do not have a default so they must be specified.
 

== Examples ==
====DctFilter====
The following example should effectively do nothing, due to a possible bug that's not the case.[http://forum.doom9.org/showthread.php?p=1191208#post1191208]
[[AviSource]]("blah.avi")
DctFilter(1,1,1,1,1,1,1,1)
 
Subtle softening:
DctFilter(1,1,1,1,1,0.75,0.25,0)
 
Remove high frequency components:[http://forum.doom9.org/showpost.php?p=298519&postcount=31]
DctFilter(1,1,1,.8,.4,0,0,0) #these settings may be prone to slight blocking
 
Measure luma variance within block (e.g. 8x8) of pixels?[http://forum.doom9.org/showthread.php?p=1689130#post1689130] 
The easiest somewhat correct "amount of variation for each block" you can get is using STD for each pixel and applying DctFilter to it (adjust the radius of STD calculation area for possibly better results).
mt_luts(last, "std", mt_square(1), "y").mt_lut("x 15 *")
DctFilter(1,0,0,0,0,0,0,0).[[GreyScale|Greyscale]]()
A reasonably close approximation with a lot better performance is an edge mask:
mt_edge("min/max", 0, 255, 0, 255).mt_lut("x 5 *")
DctFilter(1,0,0,0,0,0,0,0).[[GreyScale|Greyscale]]()
 
====DctFilterD====
DctFilterD can be used as a fast way to average 8x8 blocks:[http://forum.doom9.org/showthread.php?p=1051452#post1051452]
DCTFilterD(14) 
#DctFilter(1,0,0,0,0,0,0,0) #keeps the topmost line and leftmost row.[http://forum.doom9.org/showthread.php?p=626365#post626365]
 
Very easy way to get the normalized SAD over 8x8 blocks:[http://forum.doom9.org/showthread.php?t=150923]
mt_lutxy(clip1,clip2,"x y - abs")
DctFilterD(14)
 

== Changelog ==

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====
A large list of filters can be downloaded from the following sites but be aware that some plugins listed '''may be outdated''', only recommended as a backup.

*[http://web.archive.org/web/20130803185015/http://www.64k.it/andres/dettaglio.php?sez=avisynth Andres' Filter Collection]
*[http://chaosking.de/repo/avsfilters/ AviSynth Filter DB by ChaosKing] | [http://web.archive.org/web/20140412062911/http://chaosking.de/avisynth-filter-db mirror]
*[http://xhmikosr.1f0.de/_old/avisynth/plugins/ XhmikosR's Builds]
*[http://www.avisynth.nl/users/warpenterprises/ Warp Enterprises' AviSynth Filter Collection]

====64-bit filters====
A comprehensive list of 64-bit filters is available in the [[AviSynth%2B#AviSynth.2B_x64_plugins|AviSynth+]] page.

====AviSynth v1.0x/v2.0x plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

| This is a fast simple filter to correct the improper 4:1:1 => 4:2:2 conversion that seems to occur with some DV/4:1:1 codes when used with Avisynth. It assumes the odd chroma pixels are duplicates and discards them replacing them with the average of the two horizontally adjacent even chroma pixels. It doesn't matter whether the clip is interlaced though it must be in YUY2 format for Avisynth 2.5. There are no parameters, and currently no readme file.

| TDeint is a bi-directionally, motion adaptive (sharp) deinterlacer. It can also adaptively choose between using per-field and per-pixel motion adaptivity. It can use cubic interpolation, kernel interpolation (with temporal direction switching), or one of two forms of modified ELA interpolation which help to reduce "jaggy" edges in moving areas where interpolation must be used. TDeint also supports user overrides through an input file, and can act as a smart bobber or same frame rate deinterlacer, as well as an IVTC post-processor.

== Adjustment Filters ==

=== Borders and Cropping ===

{{FilterTable}}
|[[BorderControl]]
| It's designed to allow you to manipulate the regions at the top, bottom and sides of a frame. Set a black border, set a border region to be faded out and you can "smear" the border to save having to crop and resize the whole frame for the sake of a few pixels. Each border (top,bottom.left and right) can be manipulated independently. See [http://forum.doom9.org/showthread.php?t=33479 discussion] and [http://avisynth.org.ru/docs/english/externalfilters/bordercontrol.htm documentation].

EDIUpsizer also uses a few modifications to basic NEDI in order to prevent a lot of the artifacts that NEDI creates in detailed areas. These include condition number testing and adaptive window size ([http://web.archive.org/web/20041221052401/http://www.cs.ucdavis.edu/~bai/ECS231/finaltzeng.pdf finaltzeng.pdf]), as well as capping constraints. All modifications and constraints to NEDI are optional (can be turned on and off) and are user configurable. Just note that this filter is rather slow.

{{FilterTable}}
| [[Dither_tools|Dither]]
| Generates video with up to 16 bits per component after denoising and dithers back to 8 bits for storage. Primarily written to smooth fine gradients to remove color banding during/after denoising. Can also recover high bitdepth data potentially contained in a noisy clip; dither a high bitdepth picture into a standard YV12; and perform basic operations (masking, curves...) on high bitdepth pictures, as they cannot be manipulated safely with conventional AviSynth filters.

===Deinterlacing===
{{FilterTable}}
| GreedyHMA
| GreedyHMA is an Avisynth filter that executes DScaler's Greedy/HM algorithm code to perform pulldown matching, filtering, and video deinterlace. It has pretty much been superceded by Donald Graft's [[Decomb]] package. However there may be occasions where it sometimes gives preferable results, especially with some bad [[PAL]] clips.

| Another approach to motion compensated bobbing. No residual combing, Motion Masking adaptive to local complexity, self adaptive error correction for temporal interpolation, Motion Search between fields of same parity, and spatial Interpolation overweights spatio-temporal interpolation. Is SLOW.

SilverbackNet: /* As Yet Unclassified */ Add vcmohan filters

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====


A large list of filters can be downloaded from the following sites: 
Be aware that some plugins may be outdated, only recommended as a backup.

:*[http://web.archive.org/web/20130803185015/http://www.64k.it/andres/dettaglio.php?sez=avisynth Andres' Filter Collection]

Documentation of AviSynth v1.0x/v2.0x plugins (older plugins, not recommended, but some of them ''may'' still be in general use).
:*[[External plugins old|External plugins (old)]]

==== Using filters ====

Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

| ColorMatrix
| ColorMatrix corrects the colors of MPEG-2 streams. More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

| This is a fast simple filter to correct the improper 4:1:1 => 4:2:2 conversion that seems to occur with some DV/4:1:1 codes when used with Avisynth. It assumes the odd chroma pixels are duplicates and discards them replacing them with the average of the two horizontally adjacent even chroma pixels. It doesn't matter whether the clip is interlaced though it must be in YUY2 format for Avisynth 2.5. There are no parameters, and currently no readme file.

* High quality adaptative field matching for hard telecine
* Bob, remove the blends and decimate back to the desired framerate for DHT/field-blended

* Bob the interlaced credits, blend-deinterlacing the background while doing minimal damage on the progressive credits, convert their framerate to match the episode's and splice them with it OR leave them @ 30p to create a VFR clip
* Very good combing removal and anti-aliasing functions

| This is an adaptive local noise reduction filter. It uses global variance of the noise, local mean and local variance in a moving grid of specified size. It tries to preserve edges as closely as possible. The global variance value can be specified or it can be computed from a window. The global variance can have one value for the entire clip or can vary frame to frame linearly or computed from a window with its coordinates linearly moving with frame numbers.

| EdiUpsizer
| EDIUpsizer is a resampling filter that upsizes an image by a factor of two both horizontally and vertically using NEDI (new-edge directed interpolation). See [http://web.archive.org/web/20101126091759/http://neuron2.net/library/nedi.pdf nedi.pdf] for more info on the algorithm. EDIUpsizer also uses a few modifications to basic NEDI in order to prevent a lot of the artifacts that NEDI creates in detailed areas. These include condition number testing and adaptive window size ([http://web.archive.org/web/20041221052401/http://www.cs.ucdavis.edu/~bai/ECS231/finaltzeng.pdf finaltzeng.pdf]), as well as capping constraints. All modifications and constraints to NEDI are optional (can be turned on and off) and are user configurable. Just note that this filter is rather slow.

| TMonitor is a filter very similar to AVSMon. It enables monitoring of an Avisynth clip via previewing the video, viewing clip information (such as video width, height, colorspace, number of frames, audio samples, sample rate, number of audio channels, and more), and adjusting the audio delay. It also supports multiple instances per script, allowing viewing of differences between different parts of a processing chain.

|
| [http://www.gnu.org/licenses/gpl-2.0.txt GPLv2]
|}}
== Description ==
An experimental filter that, for each 8x8 block, will do a Discrete Cosine Transform (DCT), scale down the selected frequency values, and then reverse the process with an Inverse Discrete Cosine Transform (IDCT).
 
 
== Requirements ==
* AviSynth 2.5.8 or [http://forum.doom9.org/showthread.php?t=168764 greater]
* Supported color formats: [[YUY2]], [[YV12]]
* Width and height need to be a multiple of 16 (mod16)

* [[MMX]], [[ISSE]] or [[SSE2]] capable CPU
 
== Known Issues ==
* [http://forum.doom9.org/showthread.php?p=1191185#post1191185 Stripe bug] - both variants are buggy at calculating DC, additional information [http://forum.doom9.org/showthread.php?p=1346201#post1346201 here] and [http://forum.doom9.org/showthread.php?p=1051452#post1051452 here].
 
== [[Script variables|Syntax and Parameters]] ==
 
=== DctFilter ===
There are 8 positional floating point parameters, all of which must be specified as in the range (0.0 <= x <= 1.0). These correspond to scaling factors for the 8 rows and columns of the 8x8 DCT blocks. 
The leftmost parameter corresponds to the top row, left column. This would be the DC component of the transform and should always be left as 1.0.
 
 
:{{Template:FuncDef|DctFilter (clip, float, float, float, float, float, float, float, float, bool "chroma")}}
 
In the following example the highest frequency components in each row and column will be zeroed while the 2nd highest would be cut in half.
[[AviSource]]("Blah.avi")
DctFilter(1,1,1,1,1,1,.5,0)
The row & column parms are multiplied together to get the scale factor for each of the 64 values in a block. So if the top left value was V[0,0] then in the example above the we would scale row 6, col 6 (V[6,6]) by .5 * .5 = .25. 
Note that while they look like floating point parms above they really now only
have 3 bit accuracy so the only actual values used are 0, {{Frac|1|8}}, {{Frac|1|4}}, {{Frac|3|8}} ... 1.0. But you can specify any value and it will be rounded to the nearest one.

 
-------------
 
=== DctFilterD ===
DctFilterD works similar to DctFilter but will zero out DiagCt number of the lower right diagonals of the DCT, leaving other values unchanged. 
In an 8x8 DCT result matrix there are 15 possible diagonals (visualize a chess board), so if you specify <code>DctFilterD(4)</code> then the 4 diagonals in the lower right corner of the DCT result will be set to 0. I haven't tested this much but, like my results with custom quant tables, it appears if you set DiagCt very large you will start to get edge noise, something like ringing.[http://forum.doom9.org/showpost.php?p=266216&postcount=145]
 
 
:{{Template:FuncDef|DctFilterD (clip, int)}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2| |int| }}
:::"DiagCt" must be an integer from 1-14 saying how many of these diagonals must be zeroed, starting from the lower right hand corner.
 
-------------
 
=== DctAddConstant ===
Not much is known about this filter...
 
 
:{{Template:FuncDef|DctAddConstant (clip, float, float, float, float)}}
 

== Examples ==
====DctFilter====
The following example should effectively do nothing, due to a possible bug that's not the case.[http://forum.doom9.org/showthread.php?p=1191208#post1191208]
[[AviSource]]("blah.avi")
DctFilter(1,1,1,1,1,1,1,1)
 
Subtle softening:
DctFilter(1,1,1,1,1,0.75,0.25,0)
 
Remove high frequency components:[http://forum.doom9.org/showpost.php?p=298519&postcount=31]
DctFilter(1,1,1,.8,.4,0,0,0) #these settings may be prone to slight blocking
 
Measure luma variance within block (e.g. 8x8) of pixels?[http://forum.doom9.org/showthread.php?p=1689130#post1689130] 
The easiest somewhat correct "amount of variation for each block" you can get is using STD for each pixel and applying DctFilter to it (adjust the radius of STD calculation area for possibly better results).
mt_luts(last, "std", mt_square(1), "y").mt_lut("x 15 *")
DctFilter(1,0,0,0,0,0,0,0).[[GreyScale|Greyscale]]()
A reasonably close approximation with a lot better performance is an edge mask:
mt_edge("min/max", 0, 255, 0, 255).mt_lut("x 5 *")
DctFilter(1,0,0,0,0,0,0,0).[[GreyScale|Greyscale]]()
 
====DctFilterD====
DctFilterD can be used as a fast way to average 8x8 blocks:[http://forum.doom9.org/showthread.php?p=1051452#post1051452]
DCTFilterD(14) 
#DctFilter(1,0,0,0,0,0,0,0) #keeps the topmost line and leftmost row.[http://forum.doom9.org/showthread.php?p=626365#post626365]
 
Very easy way to get the normalized SAD over 8x8 blocks:[http://forum.doom9.org/showthread.php?t=150923]
mt_lutxy(clip1,clip2,"x y - abs")
DctFilterD(14)
 

== Changelog ==

SilverbackNet: add some defaults

{{Filter|Vit|3.32|3=[http://www.mediafire.com/?su7l5jtcobabksk Download (3.32), with English instructions] [http://www.mediafire.com/?nm188lh2oam487m Plugin Package with all Requirements] [http://www.mediafire.com/?mfs7bp2rprbhp22 Plugin Package for multithreading] [[Media:QTGMC-3.32.avsi| QTGMC-3.32.avsi]]|4=Deinterlacers|5=[[YV12]] • [[YUY2]]|7=[https://forum.doom9.org/showthread.php?t=156028 Doom9 Thread]}}
A very high quality deinterlacer with a range of features for both quality and convenience. These include a simple presets system, extensive noise processing capabilities, support for repair of progressive material, precision source matching, shutter speed simulation, etc. Originally based on [[TempGaussMC]] by Didée.

==Requirements==

Requires the latest version of the following plugins:

* [[MVTools]]
* [[MaskTools2]]
* [[nnedi3]]
* [[RemoveGrain]] (Both RemoveGrainSSE2 and RepairSSE2, do not use SSE3 versions)

Optional plugins:

* [[SSE2Tools]] for YUY2 support (SSE2Tools from RemoveGrain package)
* [[nnedi2]], [[nnedi]], [[eedi3]], [[eedi2]], [[TDeint]] - if selected manually or via a source-match preset
* [[Yadif]] - Required for preset="Ultra Fast" or if selected manually (autoloads only in [[Avisynth+]])
* [[VerticalCleaner]] - Required for SVThin or Lossless modes
* [[AddGrainC]] - Required for NoiseDeint="Generate"
* [[FFT3DFilter]] or [[dfttest]] - For enabling noise processing

FFT3DFilter and ddftest both need the [http://www.fftw.org/ FFTW3 library] ([http://www.fftw.org/install/windows.html windows builds]). On Windows extract libfftw3f-3.dll, and copy the file to fftw3.dll as well (for FFT3DFilter). Place them in the path, typically System32 or SysWow64 folder (depending on your OS and version of AviSynth).

==Getting Started==

Install AviSynth and copy the plugins from the plugin package to the correct locations. Then to use QTGMC, write a script like this:

<pre>
YourSource("yourfile") # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
QTGMC( Preset="Slow" )
SelectEven() # Add this line to keep original frame rate, leave it out for smoother doubled frame rate
</pre>

Save this script with an ".avs" extension. You can now use it as an AVI source for encoding.

''Most users should only use presets.'' The "Preset" used selects sensible settings for a given speed. Choose from:

* '''"Placebo" • "Very Slow" • "Slower" • "Slow" • "Medium" • "Fast" • "Faster" • "Very Fast" • "Super Fast" • "Ultra Fast" • "Draft"'''

The default preset is '''"Slower"'''. Don't be obsessed with using the slowest settings, the differences can be very small for a huge increase in time. In particular HD material benefits less from extreme settings. HD is 6-8 times as slow as SD.

There are many settings for tweaking this script, full details are provided in this documentation. The settings have been divided into categories, which each having key points, a detailed description, settings specifications/defaults, and several examples. The key points and examples should get you going. You can display settings currently being used with ''ShowSettings'':

QTGMC( Preset="Slow", ShowSettings=true )

===Multi-Threaded Usage===

QTGMC is very demanding on your system. For best performance try using it multi-threaded. You will need one of the "MT" versions of Avisynth from the [[Main Page]], only [http://forum.doom9.org/showthread.php?t=148782 2.6.0 MT by SEt] is supported. Use the multithreaded plugin pack in this case.

You need to tweak multi-threaded scripts to suit your system. Here is a basic template - read and follow the comments carefully and provide the values noted (you cannot use this code just as it is):

SetMTMode(5, ''X'') # See ''X'' below
SetMemoryMax(''M'') # Optional line. Leave it out at first. See ''M'' below
YourSource("yourfile") # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
SetMTMode(2)
QTGMC( Preset="Slow", EdiThreads=''Y'' ) # Choose preset based on overall speed/quality you want. See ''Y'' below
Distributor() # This line may or may not be necessary, try removing it and see if you get more speed

====SetMTMode ''X''====
* Start at the number of logical cores in your machine (note: with HyperThreading enabled, logical cores = 2x physical cores)
* If it crashes, decrease 1 at a time
* Otherwise increase 1 at a time until CPU usage just reaches 100%, don't go too far or it will slow down

====EdiThreads ''Y''====
* Start at about half number of cores and tweak upwards or downwards (but don't choose 0)
* Reducing this value may help stability, and might allow you to increase X for an overall speedup

====SetMemoryMax ''M''====
* First try without the SetMemoryMax line
* However, selecting a good SetMemoryMax value might better utilise memory and increase stability. Particularly important for slower settings
* Try values 400,600,800,1000 etc. Sometimes reducing this value can allow you to increase X for a speedup

====Notes====
* '''Do not use MT()'''.
* There are occasional instabilities with multi-threading, because AviSynth and plugins are not quite thread-safe. These instabilities affect different users in different ways: some report no issues, others can barely get multi-threading to work at all. But do try it as the speed increase can be considerable.

==Features / Settings==

'''Key Points''': For basic usage, ''select a preset and leave the core settings alone''.

===Core Settings===

'''Key Points''': Most useful setting is TR2, which controls smoothing of output.

{|
|-
| TR0
| (1,2)
| Temporal binomial smoothing radius used to create motion search clip. In general 2=quality, 1=speed
|-
| TR1
| (1,2)
| Temporal binomial smoothing radius used on interpolated clip for inital output. In general 2=quality, 1=speed
|-
| TR2
| (0,1,2,3)
| Temporal linear smoothing radius used for final stablization / denoising. Increase for smoother output
|-
| Rep0
| (int)
| Repair motion search clip (0 = off): repair unwanted blur after temporal smooth TR0
|-
| Rep1
| (int)
| Repair initial output clip (0 = off): repair unwanted blur after temporal smooth TR1
|-
| Rep2
| (int)
| Repair final output clip (0 = off): unwanted blur after temporal smooth TR2 (will also repair TR1 blur if Rep1 not used)
|-
| RepChroma
| (bool)
| Whether the repair modes affect chroma. Default: '''True'''
|}

RepX syntax: first digit (0-5): how wide thin shimmering lines can be and still get removed, from 1px to ~3px; second digit (0-3): to restore a bit beyond the detected lines. A single digit counts as the first digit.

====Examples====

QTGMC( Preset="Slow", TR2=3 ) # Strong final smooth (e.g. noisy / shimmery source)

====Algorithm Details====

The core algorithm is this:
<ol start="0">
<li> Bob the source clip. Temporally smooth the bob to remove shimmer then analyse its motion
<li> More accurately interpolate the source clip (e.g. NNEDI3). Use the motion analysis from previous step to temporally smooth this interpolate with motion compensation. This removes shimmer whilst retaining detail. Resharpen the result to counteract any blurring
<li> A final light temporal smooth to clean the result
</ol>

Stages 0 & 1 use a binomial smooth (similar to a Gaussian) to remove deinterlacing shimmer. Stage 2 uses a simple linear smoothing. Each stage's temporal radius (the number of frames out from the current) is given in the settings '''TR0''', '''TR1''' and '''TR2'''.

The shimmer reduction is critical for the algorithm so TR0 and TR1 should be at least 1. TR0 only affects the motion analysis and is only indirectly visible, increasing it to 2 will generally give a better motion match. Increasing TR1 and TR2 will create a smoother and more stable output and more strongly denoise; the downside is increased blurring and possibly lost detail, and potentially can cause stronger artifacts where motion analysis is inaccurate. The blur is partially counteracted by the sharpening settings.

The deinterlacer primarily tries to reduce "bob shimmer": horizontal lines of shimmer created when interpolating an interlaced stream. Consequently any changes made to the initial interpolation (e.g. NNEDI3) are expected to be horizontal lines of change only. The repair stages '''Rep0''', '''Rep1''' and '''Rep2''' occur after each temporal smooth. They only allow such horizontal lines of change - shimmer fixes, discarding other changes. This prevents the motion blur
that temporal smoothing could generate. The repX settings control the size of areas to allow through. (See the ''QTGMC_KeepOnlyBobShimmerFixes'' function comments for more detail.)

===Motion Analysis===

'''Key Points''': The presets make sensible choices for motion analysis. Some sources or requirements may require tweaks, but read these and MVTools2 docs first.

The bobbed source clip is sent to the MVTools2 plugin to perform motion analysis. Almost all these settings are used directly in MVTools2 functions. Read the MVTools2 documentation for more details on their purpose. Some settings can be altered for a speed / accuracy tradeoff. Less accurate motion search can result in blurring and/or oversharpening (in different circumstances) as well as slight distortions of visual elements. The faster presets gain speed by simplifying the motion search parameters, use the "ShowSettings" parameter or look at the table a short way into the script to see how.

Other settings defaults are determined by preset.

===Interpolation===

'''Key Points''': Interpolation affects quality and speed. The presets can be relied on to provide sensible defaults mostly using NNEDI3.

The first step to create the deinterlaced output is to spatially interpolate a single half-height field into a full-height frame. A variety of interpolators are supported, with various settings to control the quality/speed of the output.

{|
|-
| EdiMode
| (string)
| Interpolation method, from "NNEDI3", "NNEDI2", "NNEDI", "EEDI3+NNEDI3" (EEDI3 with sclip from NNEDI3), "EEDI3", "EEDI2", "Yadif", "TDeint" or "RepYadif" ("repaired" Yadif), anything else uses "Bob"
|-
| ChromaEdi
| (string)
| Interpolation method used for chroma. Set to "" to use EdiMode above (default). Otherwise choose from "NNEDI3", "Yadif" or "Bob" - all high speed variants. This can give a minor speed-up if using a very slow EdiMode (i.e. one of the EEDIx modes) Default: '''""'''
|-
| NNSize
| (0...6)
| Area around each pixel used as predictor for NNEDI3. A larger area is slower with better quality, read the NNEDI3 docs to see the area choices. Note: area sizes are not in increasing order (i.e. increased value doesn't always mean increased quality)
|-
| NNeurons
| (0...4)
| Controls number of neurons in NNEDI2 (0-2) & NNEDI3 (0-4), larger = slower and better quality but improvements are small
|-
| EdiQual
| (1,2,3)
| Quality setting for NNEDI2 (1,2,3) & NNEDI3 (1,2 only). Higher values for better quality - but improvements are marginal
|-
| EdiMaxD
| (1...)
| Spatial search distance for finding connecting edges in EEDI2 and EEDI3
|-
| EdiThreads
| (0...)
| Number of threads to use in EEDI3 & NNEDI2/3, 0 = default = number of logical processors on system. Also affects source-match interpolations. Source-match can add 2 further interpolations per frame, adjusting this setting can help balance system load. Default: '''0'''
|-
| EdiExt
| (clip)
| Provide externally created interpolated clip rather than use one of the above modes. Default: '''undefined'''
|}

Other settings defaults are determined by preset.

====Examples====

QTGMC( Preset="Slow", EdiMode="EEDI3", EdiMaxD=16 ) # Use EEDI3 with an explicit search radius
QTGMC( Preset="Very Slow", EdiThreads=2 ) # Specify number of threads (with default NNEDI3) useful to tweak if using SetMTMode or source-match

===Sharpness===

Key Points: Always consider adjusting the Sharpness setting to taste. The default 1.0 is fairly sharp. If using source-match the default is 0.2

The core of the algorithm involves a binomial smooth to remove shimmer. So the result needs to be resharpened to counteract this blur. The main setting Sharpness defaults to 1.0, which is a level designed to retain the sharpness of stable areas. However, this level can cause moving areas to be oversharpened so you may wish to reduce the value depending on source. Sharpness when using source-match behaves differently, see that section. The sharpness processing for a given setting is tweaked to remain roughly similar regardless of other settings. However, there will be minor differences, so always consider adjusting sharpness if you tweak other major settings.

Oversharpening is limited either spatially (SLMode = 1,3) or temporally (SLMode = 2,4). Temporal limiting is more "correct" but also more aggressive in preventing sharpening. It's also slower. You can set a small value in the overshoot setting (SOvs) to give the temporal limiting a bit of "headroom". You can also perform sharpness limiting later in the algorithm (SLMode = 3,4) for more sharpness, but with the potential for minor artefacts.
Settings
{|
|-
| Sharpness
| (0.0...)
| How much to resharpen the temporally blurred clip (default is always 1.0 unlike original TGMC)
|-
| SMode
| (0,1,2)
| Resharpening mode: 0 = none, 1 = difference from 3x3 blur kernel, 2 = vertical max/min average + 3x3 kernel
|-
| SLMode
| (0,1,2,3,4)
| Sharpness limiting: 0 = off, [1 = spatial, 2 = temporal] : before final temporal smooth, [3 = spatial, 4 = temporal] : after final temporal smooth
|-
| SLRad
| (0...)
| Temporal or spatial radius used with sharpness limiting (depends on SLMode). Temporal radius can only be 0,1 or 3
|-
| SOvs
| (0...255)
| Amount of overshoot allowed with temporal sharpness limiting (SLMode = 2,4), i.e. allow some oversharpening. Default: '''0'''
|-
| SVThin
| (0.0...)
| How much to thin down 1-pixel wide lines that have been widened due to interpolation into neighboring field lines. Default: '''0.0'''
|-
| Sbb
| (0,1,2,3)
| Back blend (blurred) difference between pre & post sharpened clip (minor fidelity improvement): 0 = Off, 1 = before (1st) sharpness limiting, 2 = after (1st) sharpness limiting, 3 = both. Default: '''0'''
|}

Other settings defaults are determined by preset.

====Examples====

QTGMC( Preset="Slow", Sharpness=0.4 ) # Reduce oversharpening
QTGMC( Preset="Slow", Sharpness=1.2, SLMode=1 ) # Increase sharpness, use spatial sharpness limiting (which typically allows more sharpening)

===Source Match / Lossless===

Very detailed section for new feature [documentation likely to be thinned as feature matures]
Note: the effects of this feature are both subtle and precise, intended only for exacting detail. Make sure you can see exacting detail first.

Key Points: Source-match creates higher fidelity output with extra processing. Enable with SourceMatch = 1,2 or 3. Higher values are slower and more accurate. Can combine with Lossless setting (especially Lossless=2) for more detail again. Tweak speed with MatchPreset (like Preset). Will honor artefacts in source, so best used with quality sources. By default Sharpness becomes 0.2 & sharpness limiting (SLMode) is switched off, so adjust sharpness carefully.

Quickstart: The templates below increase in both quality and slowness. Choose a preset as required, the very fastest presets are not suitable though. The default Sharpness=0.2 but you may wish to increase it slightly. Set TR2=1 for clean source, set TR2=2 or TR2=3 (slower) if more denoising required or use noise processing

QTGMC( Preset=XXXX, SourceMatch=1, Sharpness=XXX, TR2=X ) # Basic mode, fastest
QTGMC( Preset=XXXX, SourceMatch=1, Sharpness=XXX, TR2=X, Lossless=2 ) # Good quality, efficient, minor residual combing
QTGMC( Preset=XXXX, SourceMatch=2, Sharpness=XXX, TR2=X ) # Good quality, slower, no combing
QTGMC( Preset=XXXX, SourceMatch=3, Sharpness=XXX, TR2=X, Lossless=2 ) # Best quality, slowest, very minor residual combing

Intuitively, a deinterlacer should just inject new fields into the source, leaving the original pixels untouched. The temporal blur/resharpen in this script means that doesn't happen - the source pixels are changed in the output. The (optional) source-match steps attempt to fix this and make the result closer to the source. They work by looking at the difference between output and source at different points in the algorithm and correcting for that difference.

Matching to the source will capture more source detail and reduce oversharpening / haloing. Caveat: the default algorithm temporally smooths but with source-matching much less so (by necessity / design). Source-matching may faithfully recreate artefacts in the source (e.g blocking, banding & some noise) so it's better for quality sources. The SourceMatch setting sets the mode: 0=off (standard [Q]TGMC algorithm), 1,2,3 for progressively more accurate but slower processing. Modes 2 & 3 restore almost exact source detail but are sensitive to noise & introduce occasional aliasing (mode 3 is less affected). Mode 1 is a more conservative halfway stage that rarely introduces artefacts.

Since source-matching recovers sharpness, the Sharpness default is reduced to 0.2. Source-matching may initially appear less sharp than standard processing because it will not oversharpen. However, be careful if raising the sharpness, because sharpness limiting is switched off by default. This is because sharpness limiting reduces the the accuracy of these modes. Use the MatchEnhance setting to exaggerate additional detail found by modes 2 & 3. This gives a sharpening / detail enhancing effect and works well at sensible levels - but it's a slight cheat that should be used with care as it can easily enhance noise. Since source-match is sensitive to source noise you may want to set TR2 to 2 or 3 and/or use some noise processing (see below).

The additional Lossless modes are designed to take source-match to its logical conclusion: Lossless mode 1 restores the *exact* pixels of the source into the output (provided NoiseRestore=0). This recovers a liitle more source detail but can introduce shimmering, minor combing, noise etc. Note the Sharpness and MatchEnhance settings have little effect in lossless mode 1. Lossless mode 2 makes the clip lossless before the sharpening & final temporal smooth. This removes most of the lossless artefacts and also allows sharpness control. This mode will not give an exactly lossless output but it will gain a little more detail.

The source-match settings introduce further processing. SourceMatch mode 1 requires a second interpolation (e.g. NNEDI3), but it can use a lower quality settings than the main stage. SourceMatch mode 2 requires yet another interpolation, but works effectively with just a bob (but using a better interpolator can reduce occasional aliasing). Mode 3 adds just a little more processing and is usually worth it as it reduces artefacts. There is no exact control over the interpolations used (too many settings required), instead there are MatchPresets that work in a similar way to the main Preset. The extra processing suggests much slower speeds, but actually using higher speed presets (both MatchPreset and Preset) with source-matching can give results comparable to slower presets without it. Having said that, the extra detail from source-matching is too subtle to significantly affect very high speed main presets.

</pre>

===Noise Bypass / Denoising===

Key Points: QTGMC can remove, retain or strengthen noise and very fine detail. Has automatic "EZ" settings for simple operation. Refer to examples below

The use of multiple temporal smooths means that this script denoises by default. QTGMC can extract some noise/grain from the source at the start, then optionally restore some of it back in again at the end. This allows either denoising, or for the grain/noise from the source to be retained. For simplest operation use one of the two automatic "EZ" modes, EZDenoise or EZKeepGrain (can only use one at once) and select a NoisePreset. For manual operation there are two modes: NoiseProcess=1 actually denoises at the start, whereas NoiseProcess=2 just identifies the noise in the source without removing it. NoiseProcess=1 is typically used for stronger denoising of the output, and NoiseProcess=2 is used to retain grain or for a very light denoise.

Manual operation: after selecting a mode, set a Sigma value to estimate the level of source noise. Use the ShowNoise setting to help in this choice. Then decide how much of that noise to restore after the deinterlace. There are two restore points called GrainRestore/NoiseRestore, the amount of noise restored depends on their sum. For full denoising set them both to 0. For grain retention, a good starting point is 0.7/0.3 for NoiseProcess=1, and 0.3/0.1 for NoiseProcess=2. GrainRestore restores more stable "grain-like" detail. NoiseRestore restores finer more fluctuating noise. Usually best if GrainRestore is greater than NoiseRestore unless you want a very noisy look. Too high restoral values will give grain exaggeration and even luma changes.

Important: You must use a non-zero value in one of EZDenoise, EZKeepGrain or NoiseProcess or no noise processing will occur

* EZDenoise and EZKeepGrain set automatic values for NoiseProcess, NoiseRestore/GrainRestore and Sigma
* Denoiser, DenoiseMC, NoiseTR, NoiseDeint and StabilizeNoise settings are determined by NoisePreset
* If using manual settings be sure to override *all* the values you are interested in

====Examples====
<pre>
# Automatic Settings
QTGMC( Preset="Slower", EZDenoise=2.5, NoisePreset="Slow" ) # Automatic denoising, value is denoising strength, preset is quality/speed tradeoff
QTGMC( Preset="Slower", EZKeepGrain=1.0, NoisePreset="Faster" ) # Automatic grain retention - retain all source grain

# Denoising
QTGMC( Preset="Slower", NoiseProcess=1, NoiseRestore=0.0, Sigma=4.0 ) # Fully denoise, strength of denoising depends on Sigma setting
QTGMC( Preset="Slower", NoiseProcess=1, NoiseRestore=0.0, Denoiser="dfttest", DenoiseMC=true, NoiseTR=2, Sigma=4.0 ) # More "accurate" denoising (slower)

# Retain Noise / Grain
QTGMC( Preset="Slower", NoiseProcess=1, NoiseRestore=1.0, Sigma=2.0 ) # Retain *all* the noise / fine detail of a less noisy source
QTGMC( Preset="Slower", NoiseProcess=1, GrainRestore=1.0, Sigma=2.0 ) # Similar to above but only keep the more "stable" noise elements (depends on TR2)

# Strong Detail / Grain
QTGMC( Preset="Slower", NoiseProcess=2, GrainRestore=0.5, NoiseRestore=0.1, Sigma=2.5 ) # Using stronger mode 2, retains noise and sharpens slightly
QTGMC( Preset="Slower", NoiseProcess=2, GrainRestore=0.4, NoiseRestore=0.2, Sigma=1.8, \
NoiseDeint="Generate", StabilizeNoise=true ) # As above with better quality, more stable detail and grain
</pre>

===Progressive Input===

Key Points: Can remove horizontal shimmering effects from progressive sources. Experiment with InputType=1, 2 or 3 for best results. FPS will not be doubled

This script is designed for deinterlacing and so by default expects an interlaced clip. However, much of its operation concerns the reduction of horizontal shimmering. It is possible to use the script to remove similar shimmer from a progressive clip by using the InputType setting. InputType=1 is used for general progressive material that contains less severe problems. InputType=2,3 are designed for badly deinterlaced material with considerable horizontal artefacts. These modes drop half the fields and recreate an interlaced stream from the others, which is then treated in the normal way. Mode 3 differs from mode 2 only in that it complements field parity of the input. Generally mode 1 will retain more detail, but repair less artefacts than modes 2,3. You may consider setting TR2 to a higher value (e.g. 2 or 3) when repairing progressive material.

SourceMatch and Lossless modes are supported for progressive material. It works well for InputType=2,3, where the input is converted to an interlaced stream, and helps in detail retention. Source-match is much less useful for InputType=1

{|
|-
| InputType
| (0,1,2,3)
| Default = 0 for interlaced input. Settings 1,2 & 3 accept progressive input for deshimmer or repair. Frame rate of progressive source is not doubled. Mode 1 is for general progressive material. Modes 2 & 3 are designed for badly deinterlaced material. Default: '''0'''
|-
| ProgSADMask
| (0.0...)
| Only applies to InputType=2,3. If ProgSADMask > 0.0 then blend InputType modes 1 and 2/3 based on block motion SAD. Higher values help recover more detail, but repair less artefacts. Reasonable range about 2.0 to 20.0, or 0.0 for no blending. Default: '''10.0''' ('''0.0''' for "Fast" and faster.)
|}

====Examples====

QTGMC( Preset="Slower", InputType=1 ) # Process progressive source, it will be temporally smoothed / deshimmered
QTGMC( Preset="Slower", InputType=2, ProgSADMask=12.0 ) # Process progressive source with major artefacts, slightly favoring detail over repairs

===Shutter Speed Motion Blur / Frame Rate===

Key Points: Can output video at single or double-frame rate. For smoother playback of single-rate output there are settings to add light motion blur to simulate different shutter angles (shutter speeds)

By default QTGMC outputs video at "double-rate", twice the frame rate of the source. This is because there are two separate images (fields) in every frame, which the deinterlacing process restores in full. By setting FPSDivisor to 2, every second frame is dropped and the output frame rate is the same as the source ("single-rate")

Single-rate output may look a little stuttery, depending on how the source was filmed/created. Adding motion blur to each frame can help with this, smoothing the feel of the slower rate playback. This is done by setting ShutterBlur to 1,2 or 3, then specifying the shutter angle that you wish the output to simulate. However, as there may be some motion blur already in the source you also need to specify/estimate the shutter angle used in the source. Shutter angles range from 0 to 360, with 0 being perfectly sharp and 360 being fully blurred from one frame to next (artificial output shutter angles > 360 are supported to a very limited degree). Motion-blur can also be applied to double-rate output, but the effect is less noticable.

As motion analysis is block-based, motion blur of an object can "bleed" into surrounding, more static areas. This can be reduced using the slower ShutterBlur modes or by increasing the SBlurLimit setting (which is enabled and set to 4 by default). Both repair methods may reduce the level of motion blur a little though. In situations of complex motion the motion analysis can be incorrect, which can lead to inappropriate blurring.

{|
|-
| FPSDivisor
| (1,2...)
| 1 = Double-rate output, 2 = Single-rate output. Higher values can be used too (e.g. 60fps & FPSDivisor=3 gives 20fps output). '''Important:''' You do not need SelectEven() in the calling script if you use FPSDivisor=2. Default: '''1'''
|-
| ShutterBlur
| (0,1,2,3)
| 0 = Off, 1 = Enable, 2,3 = Higher precisions (slower). Higher precisions reduce blur "bleeding" into static areas a little. Default: '''0'''
|-
| ShutterAngleSrc
| (0...360)
| Shutter angle used in source. If necessary, estimate from motion blur seen in a single frame: 0=pin-sharp, 360=fully blurred from frame to frame. Default: '''180'''
|-
| ShutterAngleOut
| (0...360)
| Shutter angle to simulate in output. Extreme values may be rejected (depends on other settings). Cannot reduce motion blur already in the source. Default: '''180'''
|-
| SBlurLimit
| (0...)
| Limit motion blur where motion lower than given value. Increase to reduce blur "bleeding". 0=Off. Sensible range around 2-12. Default: '''4'''
|}

====Examples====

QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=30, ShutterAngleOut=180 ) # Smooth single-rate output, when input has little blur
QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=180, ShutterAngleOut=180 ) # Keep "film" look on single-rate output, "film" input
QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=2, ShutterAngleSrc=180, ShutterAngleOut=180, SBlurLimit=8 ) # Same but srongly reduce blur "bleeding"
QTGMC( Preset="Slower", FPSDivisor=1, ShutterBlur=1, ShutterAngleSrc=0, ShutterAngleOut=720 ) # Blur some high shutter-speed footage, keep double rate
# [Use of artificially high shutter angles is limited]

===Miscellaneous Settings===

Settings not covered above. Note that Border is false by default, which differs from TempGaussMC

{|
|-
| Border
| (bool)
| Pad a little vertically while processing (doesn't affect output size) - set true you see flickering on the very top or bottom line of the output. If you have wider edge effects than that, you should crop afterwards instead. Be wary of this setting if reusing QTGMC motion vectors in the calling script. Default: '''False'''
|-
| Precise
| (bool)
| Set to false to use faster algorithms with *very* slight imprecision in places
|-
| Preset
| (string)
| Sets a range of defaults for different encoding speeds. Select from "Placebo", "Very Slow", "Slower", "Slow", "Medium", "Fast", "Faster", "Very Fast", "Super Fast", "Ultra Fast" & "Draft". Default: '''"Slower"'''
|-
| Tuning
| (string)
| Tweaks the defaults for different source types. Choose from "None", "DV-SD", "DV-HD". Default: '''"None"''' [An idea for development based on the x264 approach, but as I don't work with many source types it has seen little development]
|-
| ShowSettings
| (bool)
| Display all the current parameter values - useful to find preset defaults. Default: '''False'''
|-
| GlobalNames
| (string)
| The name used to expose intermediate clips to calling script. See External Linkage section. Default: '''QTGMC'''
|-
| PrevGlobals
| (string)
| What to do with global variables from earlier QTGMC call that match above name. Either "Replace", or "Reuse" (for a speed-up). Default: '''Undefined'''
|-
| ForceTR
| (0,1,2,3)
| Ensure globally exposed motion vectors are calculated to this radius even if not needed by QTGMC. 0 = disabled. Default: '''0'''
|}

Default for Precise depends on Preset.

==External Linkage==
===Accessing QTGMC Motion Vectors===
QTGMC now exposes its motion vectors and other intermediate clips to the calling script through global variables. These globals are uniquely named. By default they begin with the prefix "QTGMC_". The available clips are:

{|
|-
| Backward motion vectors
| bVec1, bVec2, bVec3 (temporal radius 1 to 3)
|-
| Forward motion vectors
| fVec1, fVec2, fVec3
|-
| Filtered clip used for motion analysis
| srchClip
|-
| MVTools "super" clip for filtered clip
| srchSuper
|}

Not all these clips are necessarily created - it depends on your QTGMC settings. To ensure motion vector creation to radius X, set ForceTR=X

====Example====

QTGMC( Preset="Medium", ForceTR=2, SubPel=2 ) # Ensure we get temporal radius of at least 2, read note below regarding SubPel
super = MSuper( pel=2, levels=1 ) # Faster to use levels=1, don't usually need more levels once you have the vectors
MDegrain2( super, QTGMC_bVec1,QTGMC_fVec1, QTGMC_bVec2,QTGMC_fVec2 ) # Use QTGMC-created motion vectors

====Important Notes====

* The SubPel setting to QTGMC must match the pel setting in MVTools or you will get visual errors or crashes. Default SubPel in QTGMC varies depending on Preset, "Medium" and quicker settings get SubPel=1, slower settings get SubPel=2. Default pel in MVTools is 2
* Do not use Border=true if using motion vectors in this way, or the clips exposed will have an 8 pixel border top and bottom (i.e. they won't match your source)

===Multiple QTGMC Calls===
The section above showed how global variables are used to expose the workings of QTGMC. However, if there are multiple calls to QTGMC in your script then you should consider whether they should work together with their exposed globals. By default the globals for each call to QTGMC will overwrite the globals from previous calls. However there are actually three options in this case:

* Use the setting GlobalNames to make unique global names for each call. E.g. if you set GlobalNames="TestA" you will receive a global called TestA_bVec1.
* Set PrevGlobals="Reuse" to reuse existing similar named globals for this run & not recalculate motion vectors etc. This will improve performance.
* Set PrevGlobals="Replace" to overwrite similar named globals from a previous run. This is the default and easiest option for most use cases.

Here's an artifical example of multiple calls in a script to show the options:

q1 = c.QTGMC( Preset="Medium" ) # QTGMC_bVec1 and similar variables are created
q2 = c.QTGMC( Preset="Medium" ) # Recalculates and replaces variables QTGMC_bVec1 and similar with new values (same as setting PrevGlobals="Replace")
q3 = c.QTGMC( Preset="Medium", PrevGlobals="Reuse" ) # Reuses QTGMC_bVec1 motion vectors from q2 above. Doesn't recalculate, improving performance
q4 = c.QTGMC( Preset="Medium", GlobalNames="TestA" ) # Creates new variables called TestA_bVec1...
q5 = c.QTGMC( Preset="Medium", GlobalNames="TestA", PrevGlobals="Reuse" ) # Reuses the TestA_bVec1 motion vectors

Here's a realistic example. This simple script repairs progressive material with very bad deinterlacing artefacts. It needs two calls to QTGMC:

t = QTGMC( Preset="Slower", InputType=2 )
b = QTGMC( Preset="Slower", InputType=3, PrevGlobals="Reuse" ) # Reuse motion vectors from first call for a good speed-up
Repair( t, b, 1 )

==TempGaussMC Notes==
In its default setup this script is very similar in operation to TempGaussMC_beta2. The call QTGMC() is very similar to:

TempGaussMC_beta2( 2,2,1, Border=false, SVthin=0.0 )

There are a few key differences:

* QTGMC typically uses "NNEDI3" for interpolation (TempGaussMC_beta2 uses "EEDI2" by default)
* Sharpness default in QTGMC is always 1.0 (or 0.2 if using source-match) - adjusted internally to give very roughly the same sharpness across settings / presets
* In QTGMC, SVThin defaults to 0, Border defaults to false
* Lossless and Draft modes are supported but in a different way
* The parameter order is the same up to EdiMode, a couple of 'lesser' parameters have had name changes for consistency

QTGMC

2014-05-29T02:50:11Z

SilverbackNet: Partial rewrite based on the full help. Not terribly pretty.

{{Filter|Vit|3.32|3=[http://www.mediafire.com/?su7l5jtcobabksk Download (3.32), with English instructions] [http://www.mediafire.com/?nm188lh2oam487m Plugin Package with all Requirements] [http://www.mediafire.com/?mfs7bp2rprbhp22 Plugin Package for multithreading] [[Media:QTGMC-3.32.avsi| QTGMC-3.32.avsi]]|4=Deinterlacers|5=[[YV12]] • [[YUY2]]|7=[https://forum.doom9.org/showthread.php?t=156028 Doom9 Thread]}}
A very high quality deinterlacer with a range of features for both quality and convenience. These include a simple presets system, extensive noise processing capabilities, support for repair of progressive material, precision source matching, shutter speed simulation, etc. Originally based on [[TempGaussMC]] by Didée.

==Requirements==

Requires the latest version of the following plugins:

* [[MVTools]]
* [[MaskTools2]]
* [[nnedi3]]
* [[RemoveGrain]] (Both RemoveGrainSSE2 and RepairSSE2, do not use SSE3 versions)

Optional plugins:

* [[SSE2Tools]] for YUY2 support (SSE2Tools from RemoveGrain package)
* [[nnedi2]], [[nnedi]], [[eedi3]], [[eedi2]], [[TDeint]] - if selected manually or via a source-match preset
* [[Yadif]] - Required for preset="Ultra Fast" or if selected manually (autoloads only in [[Avisynth+]])
* [[VerticalCleaner]] - Required for SVThin or Lossless modes
* [[AddGrainC]] - Required for NoiseDeint="Generate"
* [[FFT3DFilter]] or [[dfttest]] - For enabling noise processing

FFT3DFilter and ddftest both need the [http://www.fftw.org/ FFTW3 library] ([http://www.fftw.org/install/windows.html windows builds]). On Windows extract libfftw3f-3.dll, and copy the file to fftw3.dll as well (for FFT3DFilter). Place them in the path, typically System32 or SysWow64 folder (depending on your OS and version of AviSynth).

==Getting Started==

Install AviSynth and copy the plugins from the plugin package to the correct locations. Then to use QTGMC, write a script like this:

<pre>
YourSource("yourfile") # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
QTGMC( Preset="Slow" )
SelectEven() # Add this line to keep original frame rate, leave it out for smoother doubled frame rate
</pre>

Save this script with an ".avs" extension. You can now use it as an AVI source for encoding.

''Most users should only use presets.'' The "Preset" used selects sensible settings for a given speed. Choose from:

* '''"Placebo" • "Very Slow" • "Slower" • "Slow" • "Medium" • "Fast" • "Faster" • "Very Fast" • "Super Fast" • "Ultra Fast" • "Draft"'''

The default preset is '''"Slower"'''. Don't be obsessed with using the slowest settings, the differences can be very small for a huge increase in time. In particular HD material benefits less from extreme settings. HD is 6-8 times as slow as SD.

There are many settings for tweaking this script, full details are provided in this documentation. The settings have been divided into categories, which each having key points, a detailed description, settings specifications/defaults, and several examples. The key points and examples should get you going. You can display settings currently being used with ''ShowSettings'':

QTGMC( Preset="Slow", ShowSettings=true )

===Multi-Threaded Usage===

QTGMC is very demanding on your system. For best performance try using it multi-threaded. You will need one of the "MT" versions of Avisynth from the [[Main Page]], only [http://forum.doom9.org/showthread.php?t=148782 2.6.0 MT by SEt] is supported. Use the multithreaded plugin pack in this case.

You need to tweak multi-threaded scripts to suit your system. Here is a basic template - read and follow the comments carefully and provide the values noted (you cannot use this code just as it is):

SetMTMode(5, ''X'') # See ''X'' below
SetMemoryMax(''M'') # Optional line. Leave it out at first. See ''M'' below
YourSource("yourfile") # DGDecode_mpeg2source, FFVideoSource, AviSource, whatever your source requires
SetMTMode(2)
QTGMC( Preset="Slow", EdiThreads=''Y'' ) # Choose preset based on overall speed/quality you want. See ''Y'' below
Distributor() # This line may or may not be necessary, try removing it and see if you get more speed

====SetMTMode ''X''====
* Start at the number of logical cores in your machine (note: with HyperThreading enabled, logical cores = 2x physical cores)
* If it crashes, decrease 1 at a time
* Otherwise increase 1 at a time until CPU usage just reaches 100%, don't go too far or it will slow down

====EdiThreads ''Y''====
* Start at about half number of cores and tweak upwards or downwards (but don't choose 0)
* Reducing this value may help stability, and might allow you to increase X for an overall speedup

====SetMemoryMax ''M''====
* First try without the SetMemoryMax line
* However, selecting a good SetMemoryMax value might better utilise memory and increase stability. Particularly important for slower settings
* Try values 400,600,800,1000 etc. Sometimes reducing this value can allow you to increase X for a speedup

====Notes====
* '''Do not use MT()'''.
* There are occasional instabilities with multi-threading, because AviSynth and plugins are not quite thread-safe. These instabilities affect different users in different ways: some report no issues, others can barely get multi-threading to work at all. But do try it as the speed increase can be considerable.

==Features / Settings==

'''Key Points''': For basic usage, ''select a preset and leave the core settings alone''.

===Core Settings===

'''Key Points''': Most useful setting is TR2, which controls smoothing of output.

{|
|-
| TR0
| (1,2)
| Temporal binomial smoothing radius used to create motion search clip. In general 2=quality, 1=speed
|-
| TR1
| (1,2)
| Temporal binomial smoothing radius used on interpolated clip for inital output. In general 2=quality, 1=speed
|-
| TR2
| (0,1,2,3)
| Temporal linear smoothing radius used for final stablization / denoising. Increase for smoother output
|-
| Rep0
| (int)
| Repair motion search clip (0 = off): repair unwanted blur after temporal smooth TR0
|-
| Rep1
| (int)
| Repair initial output clip (0 = off): repair unwanted blur after temporal smooth TR1
|-
| Rep2
| (int)
| Repair final output clip (0 = off): unwanted blur after temporal smooth TR2 (will also repair TR1 blur if Rep1 not used)
|-
| RepChroma
| (bool)
| Whether the repair modes affect chroma. Default: '''True'''
|}

RepX syntax: first digit (0-5): how wide thin shimmering lines can be and still get removed, from 1px to ~3px; second digit (0-3): to restore a bit beyond the detected lines. A single digit counts as the first digit.

====Examples====

QTGMC( Preset="Slow", TR2=3 ) # Strong final smooth (e.g. noisy / shimmery source)

====Algorithm Details====

The core algorithm is this:
<ol start="0">
<li> Bob the source clip. Temporally smooth the bob to remove shimmer then analyse its motion
<li> More accurately interpolate the source clip (e.g. NNEDI3). Use the motion analysis from previous step to temporally smooth this interpolate with motion compensation. This removes shimmer whilst retaining detail. Resharpen the result to counteract any blurring
<li> A final light temporal smooth to clean the result
</ol>

Stages 0 & 1 use a binomial smooth (similar to a Gaussian) to remove deinterlacing shimmer. Stage 2 uses a simple linear smoothing. Each stage's temporal radius (the number of frames out from the current) is given in the settings '''TR0''', '''TR1''' and '''TR2'''.

The shimmer reduction is critical for the algorithm so TR0 and TR1 should be at least 1. TR0 only affects the motion analysis and is only indirectly visible, increasing it to 2 will generally give a better motion match. Increasing TR1 and TR2 will create a smoother and more stable output and more strongly denoise; the downside is increased blurring and possibly lost detail, and potentially can cause stronger artifacts where motion analysis is inaccurate. The blur is partially counteracted by the sharpening settings.

The deinterlacer primarily tries to reduce "bob shimmer": horizontal lines of shimmer created when interpolating an interlaced stream. Consequently any changes made to the initial interpolation (e.g. NNEDI3) are expected to be horizontal lines of change only. The repair stages '''Rep0''', '''Rep1''' and '''Rep2''' occur after each temporal smooth. They only allow such horizontal lines of change - shimmer fixes, discarding other changes. This prevents the motion blur
that temporal smoothing could generate. The repX settings control the size of areas to allow through. (See the ''QTGMC_KeepOnlyBobShimmerFixes'' function comments for more detail.)

===Motion Analysis===

'''Key Points''': The presets make sensible choices for motion analysis. Some sources or requirements may require tweaks, but read these and MVTools2 docs first.

The bobbed source clip is sent to the MVTools2 plugin to perform motion analysis. Almost all these settings are used directly in MVTools2 functions. Read the MVTools2 documentation for more details on their purpose. Some settings can be altered for a speed / accuracy tradeoff. Less accurate motion search can result in blurring and/or oversharpening (in different circumstances) as well as slight distortions of visual elements. The faster presets gain speed by simplifying the motion search parameters, use the "ShowSettings" parameter or look at the table a short way into the script to see how.

Other settings defaults are determined by preset.

===Interpolation===

'''Key Points''': Interpolation affects quality and speed. The presets can be relied on to provide sensible defaults mostly using NNEDI3.

The first step to create the deinterlaced output is to spatially interpolate a single half-height field into a full-height frame. A variety of interpolators are supported, with various settings to control the quality/speed of the output.

{|
|-
| EdiMode
| (string)
| Interpolation method, from "NNEDI3", "NNEDI2", "NNEDI", "EEDI3+NNEDI3" (EEDI3 with sclip from NNEDI3), "EEDI3", "EEDI2", "Yadif", "TDeint" or "RepYadif" ("repaired" Yadif), anything else uses "Bob"
|-
| ChromaEdi
| (string)
| Interpolation method used for chroma. Set to "" to use EdiMode above (default). Otherwise choose from "NNEDI3", "Yadif" or "Bob" - all high speed variants. This can give a minor speed-up if using a very slow EdiMode (i.e. one of the EEDIx modes) Default: '''""'''
|-
| NNSize
| (0...6)
| Area around each pixel used as predictor for NNEDI3. A larger area is slower with better quality, read the NNEDI3 docs to see the area choices. Note: area sizes are not in increasing order (i.e. increased value doesn't always mean increased quality)
|-
| NNeurons
| (0...4)
| Controls number of neurons in NNEDI2 (0-2) & NNEDI3 (0-4), larger = slower and better quality but improvements are small
|-
| EdiQual
| (1,2,3)
| Quality setting for NNEDI2 (1,2,3) & NNEDI3 (1,2 only). Higher values for better quality - but improvements are marginal
|-
| EdiMaxD
| (1...)
| Spatial search distance for finding connecting edges in EEDI2 and EEDI3
|-
| EdiThreads
| (0...)
| Number of threads to use in EEDI3 & NNEDI2/3, 0 = default = number of logical processors on system. Also affects source-match interpolations. Source-match can add 2 further interpolations per frame, adjusting this setting can help balance system load. Default: '''0'''
|-
| EdiExt
| (clip)
| Provide externally created interpolated clip rather than use one of the above modes. Default: '''undefined'''
|}

Other settings defaults are determined by preset.

====Examples====

QTGMC( Preset="Slow", EdiMode="EEDI3", EdiMaxD=16 ) # Use EEDI3 with an explicit search radius
QTGMC( Preset="Very Slow", EdiThreads=2 ) # Specify number of threads (with default NNEDI3) useful to tweak if using SetMTMode or source-match

===Sharpness===

Key Points: Always consider adjusting the Sharpness setting to taste. The default 1.0 is fairly sharp. If using source-match the default is 0.2

The core of the algorithm involves a binomial smooth to remove shimmer. So the result needs to be resharpened to counteract this blur. The main setting Sharpness defaults to 1.0, which is a level designed to retain the sharpness of stable areas. However, this level can cause moving areas to be oversharpened so you may wish to reduce the value depending on source. Sharpness when using source-match behaves differently, see that section. The sharpness processing for a given setting is tweaked to remain roughly similar regardless of other settings. However, there will be minor differences, so always consider adjusting sharpness if you tweak other major settings.

Oversharpening is limited either spatially (SLMode = 1,3) or temporally (SLMode = 2,4). Temporal limiting is more "correct" but also more aggressive in preventing sharpening. It's also slower. You can set a small value in the overshoot setting (SOvs) to give the temporal limiting a bit of "headroom". You can also perform sharpness limiting later in the algorithm (SLMode = 3,4) for more sharpness, but with the potential for minor artefacts.
Settings
{|
|-
| Sharpness
| (0.0...)
| How much to resharpen the temporally blurred clip (default is always 1.0 unlike original TGMC)
|-
| SMode
| (0,1,2)
| Resharpening mode: 0 = none, 1 = difference from 3x3 blur kernel, 2 = vertical max/min average + 3x3 kernel
|-
| SLMode
| (0,1,2,3,4)
| Sharpness limiting: 0 = off, [1 = spatial, 2 = temporal] : before final temporal smooth, [3 = spatial, 4 = temporal] : after final temporal smooth
|-
| SLRad
| (0...)
| Temporal or spatial radius used with sharpness limiting (depends on SLMode). Temporal radius can only be 0,1 or 3
|-
| SOvs
| (0...255)
| Amount of overshoot allowed with temporal sharpness limiting (SLMode = 2,4), i.e. allow some oversharpening. Default: '''0'''
|-
| SVThin
| (0.0...)
| How much to thin down 1-pixel wide lines that have been widened due to interpolation into neighboring field lines. Default: '''0.0'''
|-
| Sbb
| (0,1,2,3)
| Back blend (blurred) difference between pre & post sharpened clip (minor fidelity improvement): 0 = Off, 1 = before (1st) sharpness limiting, 2 = after (1st) sharpness limiting, 3 = both. Default: '''0'''
|}

Other settings defaults are determined by preset.

====Examples====

QTGMC( Preset="Slow", Sharpness=0.4 ) # Reduce oversharpening
QTGMC( Preset="Slow", Sharpness=1.2, SLMode=1 ) # Increase sharpness, use spatial sharpness limiting (which typically allows more sharpening)

===Source Match / Lossless===

Very detailed section for new feature [documentation likely to be thinned as feature matures]
Note: the effects of this feature are both subtle and precise, intended only for exacting detail. Make sure you can see exacting detail first.

Key Points: Source-match creates higher fidelity output with extra processing. Enable with SourceMatch = 1,2 or 3. Higher values are slower and more accurate. Can combine with Lossless setting (especially Lossless=2) for more detail again. Tweak speed with MatchPreset (like Preset). Will honor artefacts in source, so best used with quality sources. By default Sharpness becomes 0.2 & sharpness limiting (SLMode) is switched off, so adjust sharpness carefully.

Quickstart: The templates below increase in both quality and slowness. Choose a preset as required, the very fastest presets are not suitable though. The default Sharpness=0.2 but you may wish to increase it slightly. Set TR2=1 for clean source, set TR2=2 or TR2=3 (slower) if more denoising required or use noise processing

QTGMC( Preset=XXXX, SourceMatch=1, Sharpness=XXX, TR2=X ) # Basic mode, fastest
QTGMC( Preset=XXXX, SourceMatch=1, Sharpness=XXX, TR2=X, Lossless=2 ) # Good quality, efficient, minor residual combing
QTGMC( Preset=XXXX, SourceMatch=2, Sharpness=XXX, TR2=X ) # Good quality, slower, no combing
QTGMC( Preset=XXXX, SourceMatch=3, Sharpness=XXX, TR2=X, Lossless=2 ) # Best quality, slowest, very minor residual combing

Intuitively, a deinterlacer should just inject new fields into the source, leaving the original pixels untouched. The temporal blur/resharpen in this script means that doesn't happen - the source pixels are changed in the output. The (optional) source-match steps attempt to fix this and make the result closer to the source. They work by looking at the difference between output and source at different points in the algorithm and correcting for that difference.

Matching to the source will capture more source detail and reduce oversharpening / haloing. Caveat: the default algorithm temporally smooths but with source-matching much less so (by necessity / design). Source-matching may faithfully recreate artefacts in the source (e.g blocking, banding & some noise) so it's better for quality sources. The SourceMatch setting sets the mode: 0=off (standard [Q]TGMC algorithm), 1,2,3 for progressively more accurate but slower processing. Modes 2 & 3 restore almost exact source detail but are sensitive to noise & introduce occasional aliasing (mode 3 is less affected). Mode 1 is a more conservative halfway stage that rarely introduces artefacts.

Since source-matching recovers sharpness, the Sharpness default is reduced to 0.2. Source-matching may initially appear less sharp than standard processing because it will not oversharpen. However, be careful if raising the sharpness, because sharpness limiting is switched off by default. This is because sharpness limiting reduces the the accuracy of these modes. Use the MatchEnhance setting to exaggerate additional detail found by modes 2 & 3. This gives a sharpening / detail enhancing effect and works well at sensible levels - but it's a slight cheat that should be used with care as it can easily enhance noise. Since source-match is sensitive to source noise you may want to set TR2 to 2 or 3 and/or use some noise processing (see below).

The additional Lossless modes are designed to take source-match to its logical conclusion: Lossless mode 1 restores the *exact* pixels of the source into the output (provided NoiseRestore=0). This recovers a liitle more source detail but can introduce shimmering, minor combing, noise etc. Note the Sharpness and MatchEnhance settings have little effect in lossless mode 1. Lossless mode 2 makes the clip lossless before the sharpening & final temporal smooth. This removes most of the lossless artefacts and also allows sharpness control. This mode will not give an exactly lossless output but it will gain a little more detail.

The source-match settings introduce further processing. SourceMatch mode 1 requires a second interpolation (e.g. NNEDI3), but it can use a lower quality settings than the main stage. SourceMatch mode 2 requires yet another interpolation, but works effectively with just a bob (but using a better interpolator can reduce occasional aliasing). Mode 3 adds just a little more processing and is usually worth it as it reduces artefacts. There is no exact control over the interpolations used (too many settings required), instead there are MatchPresets that work in a similar way to the main Preset. The extra processing suggests much slower speeds, but actually using higher speed presets (both MatchPreset and Preset) with source-matching can give results comparable to slower presets without it. Having said that, the extra detail from source-matching is too subtle to significantly affect very high speed main presets.

===Noise Bypass / Denoising===

Key Points: QTGMC can remove, retain or strengthen noise and very fine detail. Has automatic "EZ" settings for simple operation. Refer to examples below

The use of multiple temporal smooths means that this script denoises by default. QTGMC can extract some noise/grain from the source at the start, then optionally restore some of it back in again at the end. This allows either denoising, or for the grain/noise from the source to be retained. For simplest operation use one of the two automatic "EZ" modes, EZDenoise or EZKeepGrain (can only use one at once) and select a NoisePreset. For manual operation there are two modes: NoiseProcess=1 actually denoises at the start, whereas NoiseProcess=2 just identifies the noise in the source without removing it. NoiseProcess=1 is typically used for stronger denoising of the output, and NoiseProcess=2 is used to retain grain or for a very light denoise.

Manual operation: after selecting a mode, set a Sigma value to estimate the level of source noise. Use the ShowNoise setting to help in this choice. Then decide how much of that noise to restore after the deinterlace. There are two restore points called GrainRestore/NoiseRestore, the amount of noise restored depends on their sum. For full denoising set them both to 0. For grain retention, a good starting point is 0.7/0.3 for NoiseProcess=1, and 0.3/0.1 for NoiseProcess=2. GrainRestore restores more stable "grain-like" detail. NoiseRestore restores finer more fluctuating noise. Usually best if GrainRestore is greater than NoiseRestore unless you want a very noisy look. Too high restoral values will give grain exaggeration and even luma changes.

Important: You must use a non-zero value in one of EZDenoise, EZKeepGrain or NoiseProcess or no noise processing will occur

</pre>

===Progressive Input===

Key Points: Can remove horizontal shimmering effects from progressive sources. Experiment with InputType=1, 2 or 3 for best results. FPS will not be doubled

This script is designed for deinterlacing and so by default expects an interlaced clip. However, much of its operation concerns the reduction of horizontal shimmering. It is possible to use the script to remove similar shimmer from a progressive clip by using the InputType setting. InputType=1 is used for general progressive material that contains less severe problems. InputType=2,3 are designed for badly deinterlaced material with considerable horizontal artefacts. These modes drop half the fields and recreate an interlaced stream from the others, which is then treated in the normal way. Mode 3 differs from mode 2 only in that it complements field parity of the input. Generally mode 1 will retain more detail, but repair less artefacts than modes 2,3. You may consider setting TR2 to a higher value (e.g. 2 or 3) when repairing progressive material.

SourceMatch and Lossless modes are supported for progressive material. It works well for InputType=2,3, where the input is converted to an interlaced stream, and helps in detail retention. Source-match is much less useful for InputType=1

{|
|-
| InputType
| (0,1,2,3)
| Default = 0 for interlaced input. Settings 1,2 & 3 accept progressive input for deshimmer or repair. Frame rate of progressive source is not doubled. Mode 1 is for general progressive material. Modes 2 & 3 are designed for badly deinterlaced material
|-
| ProgSADMask
| (0.0...)
| Only applies to InputType=2,3. If ProgSADMask > 0.0 then blend InputType modes 1 and 2/3 based on block motion SAD. Higher values help recover more detail, but repair less artefacts. Reasonable range about 2.0 to 20.0, or 0.0 for no blending
|}

Defaults: InputType=0, ProgSADMask = 10.0 (slower presets) or 0.0 (faster presets)

====Examples====

QTGMC( Preset="Slower", InputType=1 ) # Process progressive source, it will be temporally smoothed / deshimmered
QTGMC( Preset="Slower", InputType=2, ProgSADMask=12.0 ) # Process progressive source with major artefacts, slightly favoring detail over repairs

===Shutter Speed Motion Blur / Frame Rate===

Key Points: Can output video at single or double-frame rate. For smoother playback of single-rate output there are settings to add light motion blur to simulate different shutter angles (shutter speeds)

By default QTGMC outputs video at "double-rate", twice the frame rate of the source. This is because there are two separate images (fields) in every frame, which the deinterlacing process restores in full. By setting FPSDivisor to 2, every second frame is dropped and the output frame rate is the same as the source ("single-rate")

Single-rate output may look a little stuttery, depending on how the source was filmed/created. Adding motion blur to each frame can help with this, smoothing the feel of the slower rate playback. This is done by setting ShutterBlur to 1,2 or 3, then specifying the shutter angle that you wish the output to simulate. However, as there may be some motion blur already in the source you also need to specify/estimate the shutter angle used in the source. Shutter angles range from 0 to 360, with 0 being perfectly sharp and 360 being fully blurred from one frame to next (artificial output shutter angles > 360 are supported to a very limited degree). Motion-blur can also be applied to double-rate output, but the effect is less noticable.

As motion analysis is block-based, motion blur of an object can "bleed" into surrounding, more static areas. This can be reduced using the slower ShutterBlur modes or by increasing the SBlurLimit setting (which is enabled and set to 4 by default). Both repair methods may reduce the level of motion blur a little though. In situations of complex motion the motion analysis can be incorrect, which can lead to inappropriate blurring.

{|
|-
| FPSDivisor
| (1,2...)
| 1 = Double-rate output, 2 = Single-rate output. Higher values can be used too (e.g. 60fps & FPSDivisor=3 gives 20fps output). '''Important:''' You do not need SelectEven() in the calling script if you use FPSDivisor=2
|-
| ShutterBlur
| (0,1,2,3)
| 0 = Off, 1 = Enable, 2,3 = Higher precisions (slower). Higher precisions reduce blur "bleeding" into static areas a little
|-
| ShutterAngleSrc
| (0...360)
| Shutter angle used in source. If necessary, estimate from motion blur seen in a single frame: 0=pin-sharp, 360=fully blurred from frame to frame
|-
| ShutterAngleOut
| (0...360)
| Shutter angle to simulate in output. Extreme values may be rejected (depends on other settings). Cannot reduce motion blur already in the source
|-
| SBlurLimit
| (0...)
| Limit motion blur where motion lower than given value. Increase to reduce blur "bleeding". 0=Off. Sensible range around 2-12
|}
Defaults: FPSDivisor=1, ShutterBlur=0, ShutterAngleSrc=180, ShutterAngleOut=180, SBlurLimit=4

====Examples====

QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=30, ShutterAngleOut=180 ) # Smooth single-rate output, when input has little blur
QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=180, ShutterAngleOut=180 ) # Keep "film" look on single-rate output, "film" input
QTGMC( Preset="Slower", FPSDivisor=2, ShutterBlur=2, ShutterAngleSrc=180, ShutterAngleOut=180, SBlurLimit=8 ) # Same but srongly reduce blur "bleeding"
QTGMC( Preset="Slower", FPSDivisor=1, ShutterBlur=1, ShutterAngleSrc=0, ShutterAngleOut=720 ) # Blur some high shutter-speed footage, keep double rate
# [Use of artificially high shutter angles is limited]

| Ensure globally exposed motion vectors are calculated to this radius even if not needed by QTGMC. 0 = disabled (default)
|}

Defaults: Border=false, Preset="Slower", Tuning="None", ShowSettings=false, GlobalNames="QTGMC", PrevGlobals=undefined, ForceTR=0. Default for Precise depends on Preset

==External Linkage==
===Accessing QTGMC Motion Vectors===
QTGMC now exposes its motion vectors and other intermediate clips to the calling script through global variables. These globals are uniquely named. By default they begin with the prefix "QTGMC_". The available clips are:

{|
|-
| Backward motion vectors
| bVec1, bVec2, bVec3 (temporal radius 1 to 3)
|-
| Forward motion vectors
| fVec1, fVec2, fVec3
|-
| Filtered clip used for motion analysis
| srchClip
|-
| MVTools "super" clip for filtered clip
| srchSuper
|}

Not all these clips are necessarily created - it depends on your QTGMC settings. To ensure motion vector creation to radius X, set ForceTR=X

====Example====

QTGMC( Preset="Medium", ForceTR=2, SubPel=2 ) # Ensure we get temporal radius of at least 2, read note below regarding SubPel
super = MSuper( pel=2, levels=1 ) # Faster to use levels=1, don't usually need more levels once you have the vectors
MDegrain2( super, QTGMC_bVec1,QTGMC_fVec1, QTGMC_bVec2,QTGMC_fVec2 ) # Use QTGMC-created motion vectors

====Important Notes====

* The SubPel setting to QTGMC must match the pel setting in MVTools or you will get visual errors or crashes. Default SubPel in QTGMC varies depending on Preset, "Medium" and quicker settings get SubPel=1, slower settings get SubPel=2. Default pel in MVTools is 2
* Do not use Border=true if using motion vectors in this way, or the clips exposed will have an 8 pixel border top and bottom (i.e. they won't match your source)

===Multiple QTGMC Calls===
The section above showed how global variables are used to expose the workings of QTGMC. However, if there are multiple calls to QTGMC in your script then you should consider whether they should work together with their exposed globals. By default the globals for each call to QTGMC will overwrite the globals from previous calls. However there are actually three options in this case:

* Use the setting GlobalNames to make unique global names for each call. E.g. if you set GlobalNames="TestA" you will receive a global called TestA_bVec1.
* Set PrevGlobals="Reuse" to reuse existing similar named globals for this run & not recalculate motion vectors etc. This will improve performance.
* Set PrevGlobals="Replace" to overwrite similar named globals from a previous run. This is the default and easiest option for most use cases.

Here's an artifical example of multiple calls in a script to show the options:

q1 = c.QTGMC( Preset="Medium" ) # QTGMC_bVec1 and similar variables are created
q2 = c.QTGMC( Preset="Medium" ) # Recalculates and replaces variables QTGMC_bVec1 and similar with new values (same as setting PrevGlobals="Replace")
q3 = c.QTGMC( Preset="Medium", PrevGlobals="Reuse" ) # Reuses QTGMC_bVec1 motion vectors from q2 above. Doesn't recalculate, improving performance
q4 = c.QTGMC( Preset="Medium", GlobalNames="TestA" ) # Creates new variables called TestA_bVec1...
q5 = c.QTGMC( Preset="Medium", GlobalNames="TestA", PrevGlobals="Reuse" ) # Reuses the TestA_bVec1 motion vectors

Here's a realistic example. This simple script repairs progressive material with very bad deinterlacing artefacts. It needs two calls to QTGMC:

t = QTGMC( Preset="Slower", InputType=2 )
b = QTGMC( Preset="Slower", InputType=3, PrevGlobals="Reuse" ) # Reuse motion vectors from first call for a good speed-up
Repair( t, b, 1 )

==TempGaussMC Notes==
In its default setup this script is very similar in operation to TempGaussMC_beta2. The call QTGMC() is very similar to:

TempGaussMC_beta2( 2,2,1, Border=false, SVthin=0.0 )

There are a few key differences:

* QTGMC typically uses "NNEDI3" for interpolation (TempGaussMC_beta2 uses "EEDI2" by default)
* Sharpness default in QTGMC is always 1.0 (or 0.2 if using source-match) - adjusted internally to give very roughly the same sharpness across settings / presets
* In QTGMC, SVThin defaults to 0, Border defaults to false
* Lossless and Draft modes are supported but in a different way
* The parameter order is the same up to EdiMode, a couple of 'lesser' parameters have had name changes for consistency

==Acknowledgements==
Thanks go to Didée for the script from where this began.

Also thanks to the plugin coders: Manao, Fizick, Tritical, Kassandro, Tsp, SEt, Tom Barry, Foxyshadis, TSchniede, Kurosu, mg262 and any others...

And to the many people who have given feedback, reported bugs and offered suggestions to help improve the script

Syntax Highlighting

2014-05-28T22:50:56Z

SilverbackNet: /* Notepad++ Avisynth Syntax Highlighting, by smokeslikeapoet */ newer, more complete syntax file

== Syntax highlighting in UltraEdit (by Sh0dan) ==

I've created settings for syntax highlighting in [http://www.ultraedit.com/ UltraEdit]. To use it just append it to your WORDFILE.TXT in your UltraEdit directory and change the Language ID (here 20) if necessary.

The "Plugin filters" sections contains just a few of the available filter functions.

It probably should be extended with all the commonly used ones.
