Asd-g/AviSynth-DeDot

Temporal rainbow and dotcrawl filter

Description

Dedot is a temporal cross color (rainbow) and cross luminance (dotcrawl) reduction filter.

The luma and the chroma are filtered completely independently from each other.

It doesn't filter moving objects.

This is a port of the VapourSynth plugin DeDot.

Requirements:

• AviSynth 2.60 / AviSynth+ 3.4 or later

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

Usage:

DeDot(clip, int "luma2d", int "lumaT", int "chromaT1", int "chromaT2", int "opt")

Parameters:

• clip
  A clip to process. It must be in YUV 8..16-bit planar format.

• luma2d
  Spatial threshold for the luma.
  Must be between 0 and 510.
  Lower values will make the filter process more pixels.
  If luma_2d is 510, the luma is returned without any processing.
  Default: 20.

• lumaT
  Temporal threshold for the luma.
  Must be between 0 and 255.
  Higher values will make the filter process more pixels.
  If luma_t is 0, the luma is returned without any processing.
  Default: 20.

• chromaT1
  Temporal threshold for the chroma.
  Must be between 0 and 255.
  Higher values will make the filter process more pixels.
  Default: 15.

• chromaT2
  Temporal threshold for the chroma.
  Must be between 0 and 255.
  Lower values will make the filter process more pixels.
  If chroma_t2 is 255, the chroma is returned without any processing.
  Default: 5.

• opt
  Sets which cpu optimizations to use.
  -1: Auto-detect.
  0: Use C++ code.
  1: Use SSE2 code.
  2: Use AVX2 code.
  Default: -1.

Building:

• Windows
  Use solution files.

• Linux

  Requirements:
      - Git
      - C++17 compiler
      - CMake >= 3.16
