DeCross

Revision as of 04:50, 1 April 2020

Description

DeCross is a cross color reduction plugin, useful for reducing rainbows. DeCross is based on CrossColor, an AviUtl plugin by Shou.

DeCross must be used right after the source filter, before any field matching or deinterlacing. The luma channel is returned unchanged.

Requirements

• [x86] AviSynth+ or AviSynth 2.60
• [x64] AviSynth+
• Supported color formats: YV12, YV16

Syntax and Parameters

DeCross (clip, int "ThresholdY", int "Noise", int "Margin", bool "Debug")

clip   =

Input clip.

int  ThresholdY = 30

Edge detection threshold; lower values increase edge detection.

Range: 0 - 255

int  Noise = 60

Anything equal to or greater than this value is considered as noise.

Range: 0 - 255

int  Margin = 1

Expands the edge mask left and right.

Range: 0 - 4

bool  Debug = false

Shows the area where the filter is being applied; useful for seeing the effects of ThresholdY and Margin.
