thanks Ripplin, I'll check your email.

Perhaps you could try fading the borders of the picture to make it look like it was shot with an old-time lens

Yes Nanner Split, I also thought about that, I think I could do this sort of thing on some scenes with claustrophobia feeling (like inside the wampa's cave for exemple).

find a way to remove, say, one out of every four or five frames, to make the movement look choppier.

I will give it a try. But my old cinema filter don't give much choice about the frame-rate, and I don't use it directly but as an alpha layer on premiere pro (just to get the scratches and noise). So I'll check if Premiere Pro can do what you said.
