So specifically in blender you have 3 settings really: add/subtract/multiply. Image editors such as gimp give you these and a total of 21 setting.
Are these settings in blender just a mashup of modifier settings applied across 2 strips? Or is there some kind of generic coding that all programs share for these settings? Add/subtract/multiply are found across all programs really for example. I was just curious if the other filters from gimp could be put into blender via a script.
Kinda open ended given I don't know how to script for blender, but just curious if any insights. If each filter has a generically shared code then I'm guessing you could just make a new filter name for blender and plop in these codes for each?
