Description

A modern rewrite of a simple but effective plugin to remove residual combing originally based on an AviSynth script by Didée and then written as a plugin by tritical.
This plugin also includes a fast implementation of the Vinverse2 function (yet another script written by Didée).

Requirements

• AviSynth 2.6.0 or AviSynth+
• x64 version requires AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24, YV411
  • AviSynth+: All planar Y/YUV formats (8/10/12/14/16-bits) are supported.

• Microsoft VisualC++ Redistributable Package 2022 (x86 / x64)

*** vcredist_x86.exe is required for vinverse-x86

*** vcredist_x64.exe is required for vinverse-x64

Syntax and Parameters

vinverse	(clip, float "sstr" int "amnt", int "uv", float "scl", int "opt", clip "clip2", int "thr")
vinverse2	(clip, float "sstr" int "amnt", int "uv", float "scl", int "opt")

clip   =

Input clip

float  sstr = 2.7

Strength of contra sharpening.

int  amnt =

Change no pixel by more than this.

Valid range: 0 to the maximum range the input clip's bitdepth.

Default: range_max ((2 ^ bit_depth) - 1). For example, for 8-bit is 255 and for 16-bit is 65535.

int  uv = 3

Chroma mode, as in MaskTools2:

• 1 = trash chroma
• 2 = pass chroma through (copy from input clip)
• 3 = process chroma

float  scl = 0.25

Scale factor for VshrpD*VblurD < 0

int  opt = -1

Sets which cpu optimizations to use.

• -1: Auto-detect.
• 0: Use C++ code.
• 1: Use SSE2 code.
• 2: Use AVX2 code.
• 3: Use AVX512 code.

Default: -1.

clip  clip2 =

Only applicable to vinverse.

External clip from which to take contra sharpening.

This clip must be the same length, width, height, and colorspace as the input clip.

int  thr = 0

Threshold; only applicable to vinverse.

If the absolute difference between the source and the blurred pixel is below this threshold, the pixel is just copied otherwirse it's processed.

Must be between 0 and range_max.

Default: 0 (every pixel is processed).

Examples

Vinverse with default settings:

AviSource("blah.avi")
Vinverse(sstr=2.7, amnt=255, uv=3, scl=0.25)
