[edit] Description

An AviSynth filter similar to the Channel Mixer in Adobe Photoshop CS2. 9 Adjustments are possible, 3 for each color channel.
ChannelMixer computes the following formula: 

|Rout|             |RR RG RB| |Rin|
|    |             |        | |   |
|Gout| = (1/100) * |GR GG GB| |Gin|
|    |             |        | |   |
|Bout|             |BR BG BB| |Bin|
