I have a 3 minute dance video with multiple cuts, views, and angles-- and I would like to roto brush the entire piece in After Effects. I am trying to separate the dancer from the background. Would it be wise to roto brush each cut separately (in this case I'd export each cut as a separate file from Final Cut Pro)? I am guessing yes, but not entirely sure.
When I do convert a Composition's setting to 59.94 from 29.97 (because of the Frame mismatch error) I don't see that it really changes anything....does it? Is that change only clear once full rendered (RAM previewed?) Or does it make the roto brush tool "smarter"-- more capable?
Cut up the shots. It's the only way.
Doubling the frame rate is only an option if you've separated fields on interlaced footage. The difference is that you'll see every field. I can't tell you if it's the right option without looking at the footage. You have to give it a try and step through a frame at a time to see if you have duplicates. If you do, then it's an unnecessary step.
