hey-
well, i can't get your macro to work 
but i would like to know if anyone could briefly explain this 2-3 strip process to me, Shake specific. I watched the video.... I'm able to take my image node, and use reorder to pull the red, green, and blue channels - but that's where I'm stuck. I cant seem to figure out how to pull the matte filters.... or what exactly i should do in shake right after that.
You said somebody already created a macro that does the whole process? can you point me exactly where i can find it?
Thanks,
Chris
