One thing that i ve noticed to ady's New mattes and background replacements. ( From the Ion cannon video, the new bridge shot/matte) When replacing the old windows with the new one the plate has a static grain. I was wondering if there is a way to smooth it and add an animated slight grain so background and live action is blending better. Because the static image is pop up and looks fake.

I've noticed this as well and found it distracting. It's also noticeable in the last shot of the new trailer (also a Star Destroyer bridge shot).

I don't remember why I didn't mention it before. Perhaps I was going to but forgot about it. Well, at any rate, After Effects has some very good film grain filters. Putting a very small layer of moving grain on top should mask the static grain without adding so much that it's distracting.
