I’ve tried many processes. The best so far is creating clips from the big video in PPro, then importing each into AE to key and save in a separate folder for each clip.
Each folder now has the AE file and a video clip.
I guess this will work, but I was hoping for a method to create a single file somehow. Like if I could save each file as a video clip, I’d have one file for each move (crossing arms, waving, thumbs-up, etc.) But AE requires the AE file plus the linked video file. If I delete or move any of these files, the AE file is ruined. That worries me to have so many little projects all linked to tons of little video clips, etc.
Best would be to combine all files and embed them in the AE file so it’s one file with everything. Like embedding images in Ai, when once it’s embedded it is part of the Ai file.
