Description

A simple script to reduce rainbows.


Requirements:

- AviSynth 2.5.8 or later
- Supported color formats: YUY2, YV12
- Progressive input only

Required Filters:


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.


Examples

DeRainbow with default settings: 

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