Description

A simple script to reduce rainbows.

Requirements

Required Plugins

Latest versions of the following filters are recommended unless stated otherwise.


Syntax and Parameters

DeRainbow (clip org, int "thresh", bool "interlaced")
DeRainbowYUY2 (clip org, int "thresh", bool "interlaced")


clip  org =
Input clip.


int  thresh = 10
MSharpen threshold value; default is 10 (which is fairly strong).


bool  interlaced = false
False means the input clip is progressive; with true it's interlaced. Interlaced content is processed by using SeparateFields in the beginning and Weave at the end.
Note: this parameter was added as an after-thought, it's not technically correct so use with caution and only as a last resort.


Examples

DeRainbow with default settings: 

AviSource("Blah.avi")
DeRainbow(thresh=10, interlaced=false)
