Two questions related to a flying bird:
1. What would be the best AE way/ tool to use isolate a flying bird (flying over a forest) in a video so that I can make it look like it is flying over a different object (building?)
I know there must be something more automated than rotoscoping each individual frame, point by point. It's the best only option I can figure out because the bird's wings have way too much movement, disappear and reappear as he flaps his wings, etc...
I've watched the carrot bowl video, the Beginners Tutorials, one about planars, special effects for bullets, lava, etc... but none seem to be what I'm looking for specifically.
2. As I've been rotoscoping, some of the white feather wing tips, or white head of the bird blend into the blue sky and the roto tool can't see them, so they're not being isolated with the rest of the bird. I can see those particular wingtips or head in the original, but there's just not enough differentiation for it to automatically pick it up even when I highlight the area. Any suggestions?
