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|
Requirements:
- - AviSynth 2.5.8 or later
- - Progressive input only
- - Supported color formats: RGB24, RGB32
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.
- float RR = 0.0
- Green
- float GR = 0.0
- float GG = 0.0
- float GB = 0.0
- Green-Red, Green-Green, and Green-Blue.
- float GR = 0.0
- Blue
- float BR = 0.0
- float BG = 0.0
- float BB = 0.0
- Blue-Red, Blue-Green, and Blue-Blue.
- float BR = 0.0
- Range for all parameters: -255.0 - 255.0
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)
