Answer 1:
Multicam edits are like this—>there is an edit mark where you want to change cameras, but that edit mark is just an edit mark. 2 workflows here. Manual and full auto. Full auto allows you to hit the multi cam recorder (basically a script that plays the sequence waiting for you to click to change the cams); manual is done by enclosing an area with edit marks, right click that clip, and go to multicam>Camera# where Camera# corresponds to the video track from your multi camera sequence you nested, and Audio # corresponds to the audio in your current sequence. Because they are just handled as edits and they are AUTO run in a script, you can easily move the edit mark, remove the edit mark, or even place marks that don’t go to new cameras but allow you to add effects to an area. So of course you can go back to the multi camera container, make edits, and come back and change the edits in your main output sequence.
Answer 2:
See answer 1. You can make any edit mark you want. You have to tell it when you want to change cameras between marks, but it’s a right click op that’s so easy my 5 yr old nephew’s done it when he visits.
Answer 3:
Not really. If you know the key presses for your system that allow you to go to the next panel, you might be able to jump around to the monitor you need, but, there’s no effectively easier way natively. If there’s a key press you can come up with that would work with the adobe JAVASCRIPT libraries, you might make a request of a javascript or adobe script capable friend. Personally, I’d really like to have one as well.
