[edit] 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.

[edit] Examples

DeRainbow with default settings:

DeRainbow(thresh=10, interlaced=false)
