[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|

[edit] Requirements

• AviSynth 2.5.8 or later
• Progressive input only
• Supported color formats: RGB24, RGB32

[edit] Syntax and Parameters

ChannelMixer (clip, float "RR", float "RG", float "RB", float "GR", float "GG", float "GB", float "BR", float "BG", float "BB")

Red

float  RR = 0.0

float  RG = 0.0

float  RB = 0.0

Red-Red, Red-Green, and Red-Blue.

Green

float  GR = 0.0

float  GG = 0.0

float  GB = 0.0

Green-Red, Green-Green, and Green-Blue.

Blue

float  BR = 0.0

float  BG = 0.0

float  BB = 0.0

Blue-Red, Blue-Green, and Blue-Blue.

• Range for all parameters: -255.0 - 255.0

[edit] Examples

ChannelMixer with the following settings is identical to the input. In other words; a very slow no-op.

AviSource("blah.avi")
ChannelMixer(RR=100.0, RG=0.0, RB=0.0, GR=0.0, GG=100.0, GB=0.0, BR=0.0, BG=0.0, BB=100.0)

Removing blue tint with ChannelMixer:

AviSource("blah.avi")
ChannelMixer(RR=100.0, RG=20.0, RB=-5.0, GR=0.0, GG=100.0, GB=0.0, BR=-20.0, BG=0.0, BB=100.0)
