I cant imagine why you have an entire song on a drummer in front of green screen... but that's another topic.
Cymbals and metal on desks and chairs can be a big problem.
When shooting cymbals the best thing to do is believe it or not... dirty up the cymbals. No drummer is going to want to do this to his good cymbals so you will need a pair of crappy cheap cymbals. Then rub brasso or something like it all over the top but only clean it of lightly this will muddy up the green reflections.
Since the footage is shot already.... this is for next time.
People I think are delusional about keying footage. If you want a perfect key every time, sometimes you will have to bite the bullet and roto. I have had to roto many a painful keying situation due to poor prep by someone else on a set I was never on.
Tips for the future.
- It usually takes multiple keys to get a good final key
- You will be rotoing something.
- If a part of them has holes... simply plug them with a layer on top.
~ Good luck.
The higher they fly... the much.
