I) About anime telecining

This will all be explained in the upcoming new guide.

Apply TComb before AnimeIVTC if you need to correct dotcrawl.

It is NOT recommended to use animeivtc with multithreading and/or calling it multiple times in a script. If you want to multithread it, see the examples example scripts below.

II) Function descriptions

• General settings
• Interlaced or progressive credits
• Mode=1 (Hard telecined)
• Mode=2 (Field-blended)
• Mode=3 (Double hard telecined)
• hybrid Mode=4 (Hybrid)

General parameters

mode : Required parameter. Defines the function's behavior

• • 1 : Hard telecined
  • 2 : Field blended
  • 3 : Double hard telecine
  • 4 : Hybrid

chrfix : Use to correct chroma swap between fields (to find out, apply bob() on your clip and examine the frames. If at some point the chroma of a frame is in the other and vice-versa, the issue is present).

• • True
  • False (default)

ifade : Detects and corrects interlaced fade-ins. Use for mode=1 or 4 since the clip is bobbed in mode=2 and 3.

• • True
  • False (default for speed concerns, but enabling it can be safer)

cache : Sets amount of frames to cache for all functions using scriptclip to prevent seeking issues frame order mess-up with temporal filters. Using too much will result in crashing, so use less if you get memory issues.

• • 0 to inf. (default=10)

killcomb : Removes any residual combing. Use for mode=1 or 4 since the clip is bobbed in mode=2 and 3.

• • 0 : No combing removal (default)
  • 1 : Combing removal with vinverse()
  • 2 : Slower, but more aggressive combing removal by using mcbob's method
  • 3 : Even slower, but better detail preservation and sharpness. Same as aa=3 [daa()]

aa : Antialiasing. None is necessarily better than the others, but one is more adapted to your needs. [Images/aliased.jpg without][Images/anti-aliasing.jpg with]

• • -1: Compare by interleaving the different aa options
  • 0 : No aa
  • 1 : EEDI2() based aa [can be called externally as ediaa()]
  • 2 : Average of a spatial interpolations of each fields contra-sharpening [can be called externally as daa()]
  • 3 : Edge targeted Sangnom() aa leaving the rest of the frame untouched - watch out for detail loss... if you can spare some additionnal processing time, take a look at aa=4 [can be called externally as maa()]
  • 4 : Line darkening, warp sharpening, edge targeted aa, limited sharpening and temporal stabilizing [can be called externally as SharpAAMCmod()]

The following options are meant for aa=4 [SharpAAMCmod()] aatype : Select the filter used for aa

• • "Sangnom" (default)
  • "EEDI2" (slower, but sometimes has better detail preservation than Sangnom)

dark : Line darkening strength by using Toon

• • 0 to 1 (default=0.2)

thin : Higher = thinner lines by using warpsharp

• • default = 10

sharp : Post-sharpening strength of LSFmod

• • 0 to inf. (default = 150)

smooth : Post-softening strength of LSFmod

• • 0 to 100 (default = 100)
  • -1 = The function will (try to) autocalculate a good value

stabilize : Edge stabilizing through motion compensation with MDegrain's temporal averaging - use if the edges are unstable (trembling, flickering...) or as a edge-directed smart soothe().

• • True
  • False (default)

tradius : Temporal radius (# of frames*2 1) of the stabilization.

• • 0 to 3 (default=2)

aapel : Supersampling factor for motion vector calculations when using stabilize=true. Higner = better, but slower

• • 1, 2 or 4 (default=1)

aablk : Size of the blocks for motion vector calculations when using stabilize=true. Larger blocks are less sensitive to noise, are faster, but also less accurate.

• • 4, 8 or 16 (default=8 for SD and 16 for HD)

aaov : Overlap of the blocks for motion vector calculation when using stabilize=true. Higner = better, but slower

• • Must be even and up to half aablk (default=4 for SD and 8 for HD)

Interlaced or progressive credits

i1/i2/p1/p2/e1/e2/e3 : Give the frame numbers to the function so that each section is processed correctly. Use your source's frame numbers. You do not have to specify all of them. Example - a bit of the telecined episode interlaced opening credits episode progressive ending credits next episode preview. Use e1=w,i1=x,e2=y,p1=z,e3=a.

• • i1 Last frame of the 1st interlaced section of the clip
  • i2 Last frame of the 2nd interlaced section of the clip
  • p1 Last frame of the 1st progressive section of the clip
  • p2 Last frame of the 2nd progressive section of the clip
  • e1 Last frame of the 1st telecined/double hard telecined/field blended/hybrid section of the clip
  • e2 Last frame of the 2nd telecined/double hard telecined/field blended/hybrid section of the clip
  • e3 Last frame of the 3rd telecined/double hard telecined/field blended/hybrid section of the clip

omode : Determines the output framerate

• • 1 : Converts the credits to the framerate of the episode to maintain a Constant Frame Rate. Mandatory for norm conversions.
  • 2 : Credits are maintained at 29.97 fps (half their full temporal resolution) to create a Variable Frame Rate clip. Intended for mkv files.

credconv : Determines how the credits will be converted for omode=1''''

• • "mocomp" : Use motion-compensation. Use when you have low motion backgrounds to get a blend free and stable clip.
  • "blend" : Blend frames together to reduce framerate'

overlap : Overlap of the blocks for motion vector calculation. Higner = better, but slower. Use for "mocomp".

• • 0, 2 or 4 for SD (default=4)
  • 0, 2, 4, 6 or 8 for HD (default=8)

pel : Supersampling factor for motion vector calculation. Higner = better, but slower. Use for "mocomp".

• • 1, 2 or 4 (default=2)

search : Have fun testing. 4 and 5 are usually better than 2 for roughly the same speed. Use for "mocomp".

• • 2 (Logarithmic search, also named Diamond Search)
  • 3 (Exhaustive search) - slowest, but best results SAD-wise (basically the mo-comp is done by calculating the sum of absolute differences between blocks to determine if it is the same element moving or a different one) Attempt at lame joke: no, we're not talking about this here... SAD
  • 4 (Hexagon search - similar to x264) (default)
  • 5 (Uneven Multi Hexagon search - similar to x264)

nnedi2pel : Use nnEDI2 for interpolation. True = usually better. Use for "mocomp".

• • true
  • false (default)

pass : Creating a VFR clip requires two passes. The file you must use for your final encode/subsequent filtering must be the one generated by pass=2. Use for omode=2.

• • 1 : Open with vdub, file-run video analysis pass, wait until the end, close vdub OR do a rendering pass (saving the filtered clip in a lossless (i.e. with Lagarith or HuffYUV) avi file for further use to avoid computing the same thing twice - once for analysis and another to decimate) (default)
  • 2 : Reload the same script with pass=2. Use the new avi file as source if you did a rendering pass. After all subsequent filtering, encode. Then, take the "timecode.txt" file and add it as the timecode for the video stream in mkvmerge.

rendering : If you did a rendering pass , this will only be VFR decimation based on the files written by pass=1. Use for omode=2 and pass=2.

• • True (you did a rendering pass and only want to decimate in pass=2)
  • False (you did not create any intermediate file) (default)

cbob : Higher = slower, but more precise... Here, it's almost only about quality vs speed. Use for interlaced credits.

• • 0 : Fastest, TDeint alone
  • 1 : Better (TDeint nnedi2 for interpolation)
  • 2 : Even better (TDeint nnedi2 motion mask)
  • 3 : Alternate (Yadifmod nnedi2 for interpolation)
  • 4 : Most stable bobber around - TGMC. Slow. (default)

edimode : Tells which filter to use for spatial interpolation with cbob=4. The "best" one depends on your source. Use for interlaced credits.

• • "yadif"
  • "eedi2"
  • "nnedi2" (default)

degrain : Temporal radius (# of frames to use * 2 1) for the final degraining step with cbob=4. Higher = slower more noise removal more stable. Use for interlaced credits.

• • 1 (default)
  • 2
  • 3

Hard telecine (mode=1)

precision : Higher = slower, but more precise... Here, it's only about quality vs speed.

• • 0 : Fastest, tfm only
  • 1 : Better (uses Tdeint to deinterlace)
  • 2 : Even better (Tdeint nnedi2 for interpolation)
  • 3 : Optimal (Tdeint nned2i motion mask) (default)

blend : If you have a case of blend telecine, or blend-deinterlacing of telecined footage. 3:2 pattern - 3 clear, 2 blended. Weight must be 50/50.

• • True
  • False (default)

Field blended (mode=2)

bbob : Higher = slower, but more precise... Here, it's almost only about quality vs speed. Mo-comp is not recommended for blended material, but I left in case you have stability issues with the other bobbers.

• • 0 : Fastest, TDeint alone
  • 1 : Better (TDeint nnedi2 for interpolation)
  • 2 : Even better (TDeint nnedi2 motion mask)
  • 3 : Alternate (Yadifmod nnedi2 for interpolation) (default)
  • 4 : Most stable bobber around - TGMC. Slow.

edimode : Tells which filter to use for spatial interpolation with cbob=4. The "best" one depends on your source.

• • "yadif"
  • "eedi2"
  • "nnedi2" (default)

degrain : Temporal radius (# of frames to use * 2 1) for the final degraining step with cbob=4. Higher = slower more noise removal more stable.

• • 1 (default)
  • 2
  • 3

normconv : Set to true if your source was blend-converted from PAL to NTSC or vice-versa.

• • True : Change framerate to 25fps if your source is NTSC or to 23.976fps if it's PAL
  • False : Keep 25fps if source is PAL and 23.976 if source is NTSC (default)

Double hard telecine (mode=3)

cbob : Higher = slower, but more precise... Here, it's almost only about quality vs speed.

• • 0 : Fastest, TDeint alone
  • 1 : Better (TDeint nnedi2 for interpolation)
  • 2 : Even better (TDeint nnedi2 motion mask)
  • 3 : Alternate (Yadifmod nnedi2 for interpolation)
  • 4 : Most stable bobber around - TGMC. Slow. (default)

edimode : Tells which filter to use for spatial interpolation with cbob=4. The "best" one depends on your source.

• • "yadif"
  • "eedi2"
  • "nnedi2" (default)

degrain : Temporal radius (# of frames to use * 2 1) for the final degraining step with cbob=4. Higher = slower more noise removal more stable.

• • 1 (default)
  • 2
  • 3

pattern : Tells the function how to decimate to 23.976 fps.

• • 0 Safest. Uses TDecimate. (default)
  • -1 Compare 1 to 5.
  • 1 to 5 If your source has a fixed pattern, finding it with -1 and using the appropriate one will be faster and visually better, but as soon as there's a change, everything will be a mess. Be careful.

Hybrid (mode=4)

precision : Higher = slower, but more precise... Here, it's only about quality vs speed.

• • 0 : Fastest, tfm only
  • 1 : Better (uses Tdeint to deinterlace)
  • 2 : Even better (Tdeint nnedi2 for interpolation)
  • 3 : Optimal (Tdeint nned2i motion mask) (default)

omode : Determines the output framerate

• • 1 : Converts the 30p sections to 24p by blending frames together to maintain a Constant Frame Rate.
  • 2 : 30p sections are maintained at 29.97 fps to create a Variable Frame Rate clip. Intended for mkv files.

pass : Creating a VFR clip requires two passes. Rendering passes are only recommended when you have interlaced or progressive credits or when ifade=true. You will not see the results of killcomb and aa in pass=1. The file you must use for your final encode/subsequent filtering must be the one generated by pass=2. Use for omode=2.

• • 1 : Open with vdub, file-run video analysis pass, wait until the end, close vdub OR do a rendering pass (saving the filtered clip in a lossless (i.e. with Lagarith or HuffYUV) avi file for further use to avoid computing the same thing twice - once for analysis and another to decimate) (default)
  • 2 : Reload the same script with pass=2. Use the new avi file as source if you did a rendering pass. After all subsequent filtering, encode. Then, take the "timecode.txt" file and add it as the timecode for the video stream in mkvmerge.

rendering : If you did a rendering pass , this will only be VFR decimation based on the files written by pass=1. Use for omode=2 and pass=2.

• • True (you did a rendering pass and only want to decimate in pass=2)
  • False (you did not create any intermediate file) (default)

III) Examples

AnimeIVTC is quite easy to use... if you have questions after reading this manual, please post in the AnimeIVTC thread. Here is a way to multithread it, but you can use the concept in many different ways (loading from different hard drives outputting to different hard drives and so forth). I only used 3 threads because more was too much for the source HDD, even when writing to 4 different ones. Do NOT use for VFR encodes, where analysis and decimation must be done in one shot.

 xxxsource("file.ext")
 threads = 3
 s=AnimeIVTC([settings])
 a=s.trim(0,int(framecount(s)/threads))
 b=s.trim(int(framecount(s)/threads) 1,int(framecount(s)/threads-1))
 c=s.trim(int(framecount(s)/threads-1) 1,0)
 a #load this script in vdub and save as rendering1, then change a to b and save as rendering2, ideally on a different HDD... etc etc
 
 #then, for further processing or encoding, load your different files and splice them, such as:
 #a=avisource(rendering1 file with path)
 #b=avisource(rendering2 file with path)
 a b .....
 

IV) Revisions

2.00 Released 2010-01-07 by thetoof

• • v2 because of the syntax changes
  • Compatibility with MVtools2
  • Compatibility with srestore for field blended
  • New (and better) decimation for dht
  • The user will determine the end frames of every sections in case of progressive/interlaced credits and the rest will all be done internally (no need to switch between the checks since it was a pain)
  • Handling of the blend-decimation of hybrid sections in omode=1
  • More aa and killcomb options
  • New parameter to fix chroma swap between fields
  • New parameter to fix blend telecine
  • New parameter to fix interlaced fade-ins
  • The modes are "re-thought" : mode=1 (hard telecine) mode=2 (field blended) mode=3 (double hard telecine) mode=4 (hybrid) At the moment you define a frame # for interlaced or progressive credits, the function adapts itself
  • Memory usage decreased for a few modes
  • No need to specify the region of your source (done internally) Single parameter added (bool "normconv") to go from one to another
  • More accurate external pelclip with nnedi2 for optimal motion vectors calculation
  • Rewriting of the function from scratch to prevent memory waste and other issues (I had patched with a few tricks here and there which made it harder to read. It's almost all gone now)
  • Maybe a few other things I'll add when I remember what I changed in the last year or so ;)

• • Initial release of the function.
