I've looked everywhere and I can't find anything on this. I've already tried using a colored rectangle layer set to overlay to tint the entire scene on my current project, but that just adds a color to it. I want to convert my entire scene to a sepia tone for a certain number of frames. I have a feeling this would require actionscript.

I don't want to lose the motion of my movie clips (thus making it look really bad) while I'm changing the tint for the certain length of the scene. I'm still fairly new at all this and I can't figure out if there's a way to do this without really making it look weird.

This would have been a lot easier if Flash had a "tint" option in blending mode.
