I have 2 pieces of footage- both have already been keyed (.mov's with alpha channel), so i don't have any access to the original green screen. 1 of the files has been done perfectly, i don't know if they had re-composited the footage in a 3D program or what- but compared to the other file it's like night and day. I need to try and match the bad footage to look similair to the good one... at least get close. I've tried: CC hair, inner glows, feathering edges, overlaying composition with blending modes combining those, etc etc. but haven't come up with anything to be proud of yet. Anyone have any clues on a better approach?
Looks to me like the "furriness" on the edges of the good key has been done in post - it doesn't match the colouring of the wings themselves.
I'd probably start by expanding the edges of your wings, use a blur and then Roughen Edges (Spiky) to create the feather texture, then use the result as a matte shape on a slightly enlarged duplicate of the wings. Put the original over the top so the feathery edges are underneath the original.
Obviously a bunch of experimentation and tweakng to get it right...
Ah you're the man, works like a charm.. Like you said, lots of tweaking- but it gets the job done for sure.
Thanks a lot!
