I often find myself (ie volunteer) creating videos from multiple camera sources (2 or 3 depending on project). Use for example, a 60 minute stage recital or performance. What I have been doing is taking all 3 sources and adding them to tracks on the timeline and synchronizing them by the audio tracks. So far so good, as it works well at least, and does not require too much effort to get them synchronized. Then what I do is essentially cut from one video source to another to add interest, focus in on certain things, etc. All this is pretty basic stuff, I know, but I am not sure I am doing the best way possible. What I essentially do is put the main video source (i.e. the wide angle full shot camera) on the 1st video track and leave that 100% composited). Then I add a compositing envelope to the other two tracks, and bring them up to 100% composited when I "cut" to that source, and then back to 0%. Sometimes I put the points or nodes right on top of each other for a quick cut, sometimes, I'll offset them in the timeline for a fade in of the track on top. I do not ever split the tracks, or trim them, because I do not want to lost my time sync between each of the video sources (which are typically single clips on each track).

Is there a better way to do this? Am I doing it the best and most efficient way possible?

One drawback is that you have to be very careful, when moving points on the composite envelope to make sure that you take them to either 0% or 100%. This takes extra care and time to carefully place each one, or by right-clicking and choosing to set them to 0% or 100%. I just noticed a couple of spots in one finished project that I must not have done that, and could see a very faint bleed through of one of the other video tracks, and need to go back and find that spot to see if I had left one of the upper tracks not pulled down to 0% on the envelope.

I would love to hear others' thoughts on the best ways to do this sort of work.

Thanks.
