SOP/Sat Effect
This is the FilterFrei0r-sopsat MLT frame work filter. It changes Slope, Offset, and Power of the color components, and the overall Saturation, according to the ASC CDL (Color Decision List) reference
Changing the slope means multiplying the pixel value with a constant value. Black pixels will remain black, whileas brighter ones will be changed. All effects can be observed well when applied on a greyscale gradient and looking at the RGB Parade monitor.
You can use this effect to achieve proper white balance.
See Granjow's blog where he uses the effect to adjust white balance of a clip.
