Here's the deal. My editor has. finished editing my movie that was shot with 7D and edited in Avid. Now it's my turn to composit the special effects on it. There's only one scene that requires compositing (few gunshots, smoke, muzzle flashes, etc.)
I'm really interested in its workflow. The export has to be Apple Prores422. Currently I have a HD version of the movie, but it was exported in H264 so I was able to download the 10 mins within a half an hour (my editor works abroad so she had to upload the file for me, but the fullres would have been 20 gigs or so).
Is it possible to work in AE on the H264 version and be able to put the whole thing on the fullres?
I'm not quite sure how to do this, but it seems silly to me to import the whole fullres movie into AE and let the computer die trying to render unnecessary files.
