DeCross is a spatio-temporal cross color (rainbow) reduction filter. DeCross must be used right after the source filter, before any field matching or deinterlacing. The luma channel is returned unchanged.

[edit] Description

DeCross is a spatio-temporal cross color (rainbow) reduction filter. DeCross must be used right after the source filter, before any field matching or deinterlacing. The luma channel is returned unchanged.

DeCross is based on CrossColor, an AviUtl plugin by Shou.

[edit] Requirements


*** vc_redist.x86.exe is required for DeCross-x86
*** vc_redist.x64.exe is required for DeCross-x64


[edit] Syntax and Parameters

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


clip   =
Input clip. It must have constant format and dimensions and it must be YUV420P8 or YUV422P8.


int  ThresholdY = 30
Edge detection threshold; smaller values will detect and filter more edges.
Range: 0 - 255


int  Noise = 60
Luma difference thresholh; smaller values will filter more conservatively.
Anything equal to or greater than this value is considered as noise.
Range: 0 - 255


int  Margin = 1
Expands the edge mask to the left and right by margin pixels..
Range: 0 - 4


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


[edit] Examples

DeCross with all default values: 

AviSource("Blah.avi")
DeCross(ThresholdY=30, Noise=60, Margin=1, Debug=false)
