Given all the performane issues involved with multi track editing in
Cinelerra, where every track is effectively rendered anyway. Is there
any existing option to get a video track output into a separate viewer /
compositor? Read: give me a window that only shows what is on this track.
Do you just want one track at a time, or N tracks but where N less than total number of cameras?
In first case hopefully just separate window with same track toggles as we already have will do, in other cases ....
Did you tried proxy editing, in theory it should give you better performance?
There already option to move Compositor to separate X screen, do you want something else?
