Key / mask using chroma colour on part of a moving item
Say I record a video of me drumming. If I colour the end of the sticks, chroma green or something, could I use that
1. for tracking
2. to key out the colour and just replace it with a generic drumstick white
3. then link a particle emitter (thingy) to the drum stick ends and have sparks or what have you exploding as they hit the cymbals
If I then add similarly coloured dots to the cymbals could I use that to dynamically track a plane (?) applied to the cymbal for particle bounce or whatever effect I want to do there?
This is probably a question better answered by reading a web page somewhere discussing green screen and motion tracking with blue dots or something, so if there is such a page, or book, or video, please let me know and I'll go read or watch it.
