Creates a greyscale image from an RGB24 source, it has 3 parameters to specify how much of each color channel is used.

chanmix (clip, float "r", float "g", float "b")

clip =

Input clip.

float r = 1.0

float g = 1.0

float b = 1.0

The weight of each color channel.

Gray = (red*r + green*g + blue*b) / (r+g+b)

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)
