I like doing music videos and I also record sports using 2 or more cameras. In the past I've synced up the video and audio clips, and then just used composite envelopes to display the various tracks to make it appear as if I've cut to different cameras. I've run into an issue though with the latest project I'm working on, since it used a green screen.

It seems that adding a simple composite envelope for each track has some undesirable side effects when using chroma keying, such as tracks bleeding though. I'm assuming composite envelopes is *not* the correct way to switch between visible tracks, at least in this scenario. I'd like to be able to switch between the various green screened tracks, which also have associated generated media tied to them. E.g. one track has a lava generated media playing in the non-masked area as the background.

Any tips or tricks for switching between multiple tracks which have chroma keys applied so that each track is its own individual entity that can be displayed independently? I'd rather avoid hacking the clips apart with splitting and deleting sections if at all possible. Thank you!
