About MVTools

MVTools plugin for AviSynth 2.6 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 old MVTools thread, true motion thread, 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 1: The plugin is still under development. Version 2.5.11.22 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.

Notes 2: The pfmod branch (2.7.x.x.) supports YV16 and YV24 colorspaces under AviSynth 2.6 and AviSynth+ versions. Stacked 16 bit output for MDegrain1-6 and MDegrainN are also supported in general. Native 10-16 bit colorspaces (and 32 bit float in MDegrain) are available when using MVTools with AviSynth+ r2294-.

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.

  • 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).

When using with bit depth clips, this parameter is normalized to the proper bit depth, no special scaling needed.

  • 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 % ).
  • 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 ).
  • 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.

Changelog

Version Date Author Changes
2.7.27 20180318 pinterf Fix: MDepan: use zerow parameter. The parameter had no effect probably since it had been introduced.

MDepan: report MT mode for Avisynth+. MT_MULTI_INSTANCE, except for logfile writing output mode when it reports MT_SERIALIZED. (other filters already have proper registration, MDepan was missed)

2.7.26 20180314 pinterf New: MDegrain1-6 and N: new parameter bool "out16" = false. If set, 8 bit input results in native 16bit output (like lsb=true hack but this is native, faster).

Faster: special 10 bit SAD functions instead of the generic 10-16bit one.

2.7.25 20180227 pinterf Fix: x64: not-cleared mmx state in MSuper assembly code would cause crash later, e.g. in x264 encoding, depending on following filters.

Fix: MSCDetection SC value parameter name to Ysc from Yth (must be an ancient typo), docs are OK, but the fix is mentioned in docs
MSuper: import 8 bit sse2 interpolators from mvtools-vs. Extend them for 10-16bits (faster super clip). Some filters are still todo.
MSuper: support 32bit float clips, which can be used later by MDegrains (but not for MAnalyse)
MDegrains: allow degraining clip with different bit depth from vectors. Clip and Super must be the same bit depth
MDegrains: consistently use limit and limitC, 255 do nothing, otherwise scale 0-254 value to the current bit-depth range
Overlaps: more correct internal rounding for 8 bits
Overlaps: round for 16bits
Overlaps: 32bit float (but still use the original 11 bit window constants)
Project: change from yasm to nasm.

2.7.24 20171205 pinterf Fix: MFlowBlur: possible access violation crash when nPel>1

New: MScaleVect parameter 'bits'. e.g. Analyze 8 bit clips, use their vectors for 16 bits
Move project to VS2017

2.7.23 20171012 pinterf Fix: MScaleVect wrong rounding of scaled motion vectors with negative components. e.g. proper scaling (-1;-2) to (-2;-4) instead of (-1,-3)

Fix: [DCT 8x8@8bit] garbage on x64: internal assembly code did not save xmm6/xmm7
Fix: [DCT 8x8@8bit] safe multithreading for integer DCT (8x8 block size, 8 bit video): assembly had a single working buffer.
Fix: [MDegrain] did not release input motion vector clips in destructor, possible hang at script closing. Bug since 2.7.1.22 (introducing MDegrain4/5)
Mod: fftw conversion constant of sqrt(2)/2 is more accurate (was:0.707), 16 bit formats may benefit (by feisty2)
Fix: SSE4 assembly instructions in x64, broke on non-SSE4 processors

2.7.21.22 20170629 pinterf Mod: [MMask] Faster: request source frame only for kind=5.

2.7.19.22 2017.05.25 pinterf New: [MMask] Support any planar input video formats e.g. greyscale, Planar RGB. Input clip can even be of different bit depth or format from vector's original format. For kind==5 where U and V is filled, the greyscale option is not allowed

Mod: [MMask] Faster: request source frame only for kind=5.
Fix: [MxxxxFPS,MMask]: MakeVectorOcclusionMaskTime garbage in bottom blocks
Fix: [MMask] bottom padding garbage for padded frame dimension
Fix: [MMask] proper 10+ bits scene change values (for default: 1023, 4095, 16383, 65535. Was: 65535). Parameter is still in 8-bit range
Fix: [MRecalculate] prevent overflow during thSAD scaling in 16 bits or large block sizes (32, 48...)
Fix: [DepanEstimate] Sometimes giving wrong motion instead of scene change detection. Bug only existed in previous pfmod builds.
Fix: [MAnalyze] Possible overflow in MAnalyze 8 bit, block size 48x48 and above. Overflow-safe predictor recalc for big block sizes.

Fix: DCT is fast again for non 8x8 blocksizes. Regression since 2.7.5.22.
New: Chroma SAD is now always half of luma SAD, regardless of video format. Without this: YV24's luma:chroma SAD ratio is 4:8 instead of 4:2 (of YV12)
New: MAnalyze, MRecalculate new parameter: "scaleCSAD" integer, default 0.
Fine tune chroma SAD weight relative to luma SAD.
ScaleCSAD values for luma:chroma SAD ratio

  • -2: 4:0.5
  • -1: 4:1
  • 0: 4:2 (default, same as the native ratio for YV12)
  • 1: 4:4
  • 2: 4:8

New: Block sizes 64, 48, 24, 12, 6.
MAnalyze/MRecalculate new block sizes (SATD support mod4 sizes)
Note: some smaller block sizes can only be available in 4:4:4 formats, due to block size division (chroma subsampling)
New: All block sizes are supported in MDegrain1-6, MDegrainN, and MScaleVect
New: Changed to 2017 version of asm files for 8 bit SAD/SATD functions from x265 project. Added not implemented asm code for 12, 24, 48 sizes
For some block sizes AVX2 and SSE4 is supported (AVX2 if reported under AviSynth+) e.g. BlkSize 32 is faster now.
New: MMask SAD Mask to give identical weights for other-than-YV12 formats, e.g. for YV24

2.7.17.22 2017.04.26 pinterf Fix: Regression in 2.7.16.22: MDegrain right pixel artifacts on non-modulo 16 widths

Misc: MMask, mode SADMask output is normalized further by video subsampling (YV16/YV24 has larger SAD value due to bigger chroma part that classic YV12)

2.7.16.22 2017.04.23 pinterf Fix: MMask 10-16 bits

Fix: MRecalculate 14-16 bits passed nSCD1=999999 internally which caused overflow (scene change problems later)
Fix is done by clamping SCD1 to 8*8*(255-0) (maximum value of sum of SADs on a 8x8 block)
Misc: MDegrainX 8 bits: internal 16 bit buffer to 8 bits: SSE2
Fix: MFlow access violation in internal mv resizer when resizing factor was big (MCaWarpSharp3 4x supersampling case) (bug possibly introduced in upstream 2.5.11.22)

2.7.15.22 2017.03.16 pinterf Fix: 16 bit SAD for non-AVX code path

Misc: MDegrain1-6: add error on lsb_flag=true for non-8 bit sources

2.7.14.22 2017.02.06 pinterf Fix: MAnalyze divide=2 showed "vector clip is too small" (inherited from 2.6.0.5, sanity check was done but length was not filled for divideextra data)

Fix: MFlow access violation in internal mv resizer when resizing factor was big (MCaWarpSharp3 4x supersampling case) (bug possibly introduced in upstream 2.5.11.22)

2.7.13.22 2017.02.01 pinterf Fix: MDegrain1-6,N 10-16 bit thSCD scaling

Fix: MVShow: tolerance scaling for 10-16 bits

2.7.12.22 2017.01.20 pinterf New: Faster SATD (dct=5..10) 8 bit: updated x264 function selectors, SSE2/4/AVX/AVX2; +10% speed for a whole typical MDegrain3 process on i7-3770

New: Much Faster SATD (dct=5..10) 10-16 bit: SSE2/SSE4 instead of C +50% speed for a whole typical MDegrain3 process (which is approx half speed of 8 bit)

2.7.11.22 2017.01.16 pinterf New: MDegrain6

Mod: MDegrain1-6 SSE4 for 10-16 bit (was: C. 3-5% gain, wasn't bottleneck)

2.7.10.22 2016.12.28 pinterf Fix: for YV12 the debug info text chroma part was positioned at wrong place
2.7.9.22 2016.12.20 pinterf Apply 2.5.11.9-svp analysis speedup, mainly when chroma is involved
2.7.8.22 2016.12.18 pinterf Fix: YUY2 input access violation (regression after 2.7.0.22d) - Fixed also in Depan.dll

Fix: MDegrain: free up YUY2 planes only if not planar input (bug inherited from 2.5.11.22 MDegrain3) resulting in freeze at script exit

2.7.7.22 2016.12.14 pinterf Optimizing 8 bits

speed: change some 8 bit SAD functions for the better
speed: separating bottleneck 8 bit/16 bit code paths in order not to use slower int64 calculations for 8 bit, where there are no integer overflow problems
speed: more __forceinlines for helping the compiler
info: general speed gain of 5-15% compared to 2.7.6.22, much reduced speed gap compared to the "classic" YV12 8 bit mvtools2 versions

2.7.6.22 2016.12.04 pinterf fix: sumLumaChange underflow (used for dct=2,6,9) (regression during 16 bit support)

fix: MeanLumaChange scale for 10-16 bits (used for dct=2,6,9)
fix: Mask fix: 8 bit mask resizer bug in SIMD intrinsics (regression on inline asm -> SIMD transition)
Fix: dctmode=1,2: pixel distance was not corrected for 16 bit pixel sizes
speed: Let's help VS2015 with some __forceinline directives to recognize the truth.
speed: Misc optimizations throughout the code (bit shifts instead of div or mul)
speed: FFTW DCT: C code replaced with SIMD SSE2/SSE4 (FloatToBytes, BytesToFloat)
speed: 16 bit SAD: a few optimizations in SSE2, AVX-coded SSE2 and AVX2 codepath
VS2015 compiler: /MT -> /MD (from static to dynamic dlls - now it reallys need VS2015 redistributables)

2.7.5.22 2016.11.19 pinterf Milestone release:

MCompensate: added multi-compensation mode for easy use with temporal filters.
MAnalyse, MSuper, MCompensate, MDegrainN: added multithreading (but partially, not for all code paths) using AVSTP.
MAnalyse: fixed a corruption of the global motion vector.
Improved page setting for this documentation.

2.5.14.2 2012.01.10 Firesledge Fixed MScaleVect with multi-vector clips.
2.5.14.1 2011.12.13 Firesledge Fixed crashes in the MDegrain functions when using both planar=true and lsb=true.
2.5.14.0 2011.11.28 Firesledge and Vit Added MStoreVect, MRestoreVect and MScaleVect from the Vit's MVExtras plugin.
2.5.13.1 2011.11.09 Firesledge

MAnalyse, MRecalculate: added an SATD approximation for blksize > 16 and dct ≥ 5. Previously, the SATD calculation was silently bypassed and always returned a null SAD value.
Functions now check that the pel setting is the same in the superclip and the motion vectors, instead of crashing if not.

2.5.13.0 beta 2011.09.11 Firesledge

MRecalculate: Can now process multi-vector clips.
All functions: Added the -Vit-'s fix that could improve the multithreading stability.

2.5.12.1 beta 2011.09.10 Firesledge MAnalyse: Fixed the ghosting bug introduced in the previous version.
2.5.12.0 beta 2011.09.10 Firesledge

MDegrainN added.
MAnalyse: Added the "multi" mode for MDegrainN.
MAnalyse: Documented the negative delta values and fixed some functions accordingly.
MFlowInter: Fixed the YUY2 planar mode.

2.5.11.2 beta mod16b 2011.05.11 Firesledge Fixed a regression in MDegrain1/2/3, related to the mod16 versions. thSADC is now taken into account correctly (instead of using thSAD).
2.5.11.2 beta mod16a 2011.04.10 Firesledge Merged 2.5.11.2 and 2.5.11 mod16a versions.

Changelog up to v2.5.11.22
