Description

Vinverse is a simple filter to remove residual combing, based on an AviSynth script by Didée and originally written by tritical.

This plugin also includes a fast implementation of Vinverse2 function.

Requirements:

• AviSynth 2.60 / AviSynth+ 3.4 or later

• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here) (Windows only)

Usage:

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

vinverse2 (clip input, float "sstr", int "amnt", int "uv", float "scl", int "opt")

Parameters:

• input
  A clip to process.
  Must be in YUV 8..16-bit planar format.

• sstr
  Strength of contra sharpening.
  Default: 2.7.

• amnt
  Change no pixel by more than this.
  Must be between 0 and range_max.
  Default: range_max ((2 ^ bit_depth) - 1).

• uv
  Chroma mode.
  1: Return garbage.
  2: Copy plane.
  3: Process plane.
  Default: 3.

• scl
  Scale factor for VshrpD*VblurD < 0.
  Default: 0.25.

• opt
  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.

• clip2 (vinverse only)
  External clip from which to take contra sharpening.
  This clip must be the same length, width, height, and colorspace as the input clip.

• thr (vinverse only)
  Threshold.
  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).

Building:

• Windows
  Use solution files.

• Linux
