RgTools is a modern rewrite of RemoveGrain, Repair, BackwardClense, Clense, ForwardClense and VerticalCleaner all in a single plugin. RgTools is mostly backward compatible with the original plugins, incompatibilities mainly come from deprecated parameters in the original filters, read filter documentation for full details. Some routines might be slightly less efficient than original, some are faster. Output of some RemoveGrain modes are not exactly identical to the original due to some minor rounding differences; these differences will not affect your output in any significant way (it might make it better)[1]. Other functions should be identical.


  • AviSynth 2.6.0 or greater
  • x64 version requires AviSynth+ r1576 or later
  • Supported color formats: Y8, YV12, YV16, YV24, YV411; YUV(A) and planar RGB(A) 10-16 bits on Avisynth+ r2290- and 32 bit float on Avisynth+ r2728-
  • AVX2 support requires Avisynth+ (also OS dependent, AVX2 needs at least Windows7 SP1)

or older versions

*** vcredist_x86.exe is required for RgTools-x86
*** vcredist_x64.exe is required for RgTools-x64


Filter Description Color format

Modified version of Clense that works on current and previous frames.

Y8, YV12, YV16, YV24, YV411

Temporal median of three frames.

Y8, YV12, YV16, YV24, YV411

Modified version of Clense that works on current and next frames.

Y8, YV12, YV16, YV24, YV411

Repairs unwanted artifacts from (but not limited to) RemoveGrain, includes 24 modes.

Y8, YV12, YV16, YV24, YV411

Purely spatial denoising function, includes 24 modes.

Y8, YV12, YV16, YV24, YV411

A very fast vertical median, it only has 2 modes.

Y8, YV12, YV16, YV24, YV411


Version      Date            Changes
v0.97 07/02/2018 - Remove some inherited clipping to 0..1 range for 32bit float. In general we do not clamp in 32 bit float colorspaces, especially that U/V range is -0.5..+0.5 from Avisynth+ r2728 v0.96 06/09/2017 - RemoveGrain: AVX2. Available when Avisynth+ reports AVX2 usability Can be disabled with new parameter: optAvx2=false - Clense, ForwardClense, BackwardClense: ignore planar colorspace checking when planar=true. Like in RemoveGrain and Repair. - Fix: Mode 11 and 13 for 32 bit float colorspaces (which worked like mode 10 and 12) v0.95 03/14/2017 - Fix: RemoveGrain Mode 20: overflow at 14 and 16 bit depths in SSE4 (stripes) - Repair: error on unaligned frames (unaligned crop) instead of access violation error v0.94 01/26/2017 - Clense: new parameter (from v0.9): bool reduceflicker (default false) - Clense: dummy compatibility parameters: bool planar, int cache - autoregister filter MT modes as NICE_FILTER for Avisynth+ except for Clense: when reduceflicker is true, MULTI_INSTANCE MT mode is reported - alignment check in Repair and RemoveGrain (anti-unaligned crop measures) v0.93 11/27/2016 - Same functionality as 0.92.1 - New bit depths 10, 12, 14, 16 bits and 32 bit float - New formats: Planar RGB, Planar RGBA and YUVA support - Use aligned loads if possible, internally - 10+ bit formats require SSE4 for fast processing - XP Support - Built with VS2015, requires Visual Studio Redistributable Update 3 or newer - Of course it works with classic Avisynth for 8 bit videos.
v0.92.1 02/10/2014 - Planar parameter added to VerticalCleaner registration function. It worked before but apparently not.
v0.92 02/10/2014 - Planar parameter added to VerticalCleaner for compatibility with QTGMC. Same behavior as in RemoveGrain.
v0.91 11/30/2013 - Planar parameter is added to RemoveGrain and Repair. It allows to skip any colorspace checks whatsoever, making the filter always assume that planar input is passed.
v0.9 11/26/2013 - Initial release - 24 modes of RemoveGrain, 24 modes of Repair, both modes of VerticalCleaner, and three variations of Clense implemented.
