I've been redoing some of my simple alterations )wipes, etc) so they're now done with Avisynth filters instead of being a generated image sequence which was then converted to an AVI and inserted with Avisynth. For example, instead of colour-replacing in Photoshop, I'm now fixing the bad blue screen errors with my Avisynth filter, which means I can quickly apply it to any shot.
I'm also now going through and "repainting" the red eyes in Vader's mask. Previously this would have meant painting each frame in Photoshop (or at least, writing something to load each image, repaint it, and save it, then encode the sequence to AVI...), but now I can fix hundreds of frames in a few minutes. Using filters means I can also fix frames that have already been edited in some way, e.g. where I've already repainted lightsabres. Previously this would have meant re-encoding the inserted AVI - losing a generation doesn't mean much with MJPEG, but I still wouldn't want to do it.
And before anyone asks, no, it won't be colour corrected

PS Quick plug for this piece of software, without which I would have to redo my replacement projection of Alderaan. Serves me right for always shift-deleting...
