Description
Creates a greyscale image from an RGB24 source, it has 3 parameters to specify how much of each color channel is used.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: RGB24
Syntax and Parameters
- chanmix (clip, float "r", float "g", float "b")
- clip =
- Input clip.
- clip =
- float r = 1.0
- float g = 1.0
- float b = 1.0
- float r = 1.0
- The weight of each color channel.
- Gray = (red*r + green*g + blue*b) / (r+g+b)
Examples
ChanMix with default settings:
AviSource("blah.avi") chanmix(r=1.0, g=1.0, b=1.0)
Here are some examples where ChanMix is visually identical (but slower) to Greyscale:
# Identical to Greyscale(matrix="Rec601") AviSource("blah.avi") chanmix(r=0.299, g=0.587, b=0.114)
# Identical to Greyscale(matrix="Rec709") AviSource("blah.avi") chanmix(r=0.2126, g=0.7152, b=0.0722)
# Identical to Greyscale(matrix="Average") AviSource("blah.avi") chanmix(r=0.333333, g=0.333333, b=0.333333)
ChanMix with luma coefficients from Rec. 2020:
AviSource("blah.avi") chanmix(r=0.2627, g=0.6780, b=0.0593)
