@g-force: Very interesting script! I'll make sure to try that out.
EDIT: I tried it right now, since I have frame-synched ANH 97 SE to the 2004 SE it was the perfect test-candidate. It looked like it worked quite well, except I noticed in lots of parts the script raised the black level.
So is there any way for you to change the script so the black and white levels are locked in place but the colors are still changed?
