OK, so since it seems like I'll be working with an increasing number of film-based sources, I'd really like to learn how to do film cleanup and I don't even know where to begin. What I want is basic denoising for when I need to match grain-levels to other sources but mainly, I need a way, to automatically remove dirt and spots - it doesn't really matter, if it mistakenly erases other details, like stars and stuff like that, since I would then only utilize the cleaned up version for manual cleanup in After Effects.

Oh and some good image stabilization, which would only remove gate-weave would also be totally awesome.

Doing this kind of thing in After Effects is less than ideal, since it was never made for film-restoration and I also tried PF Clean and I just couldn't get it to work but I couldn't afford the full version of PF Clean anyway, so I'd really like to learn how to do by myself what Laserschwert has been doing for me so far, so that I don't have to bother him with it. So I guess my question really is how to do this sort of thing in Avisynth.
