I use multi-cam a lot (in MEP 2015 Plus), and when it works it is brilliant. When it gets in a strop it becomes useless. I'm wondering if there are others who use multi-cam who have experienced and overcome any of its apparent idiosyncrasies - if so, I'd really appreciate any tips. There is some coverage in the PDF Help system of how to use it, but I am suspicious that the whole facility has not been really stress tested hard.

I could write a long diatribe about the exact way I use multi-cam mode, but I think its boredom factor might outweigh any usefulness.  Instead let me just try a short summary.

My typical usage:
1920x1080i, three or four cameras. Long takes on each camera of an hour or more, all recording the same classical concert material from different angles. Set up on track number 3 downwards and synced via clapperboard. Separate master audio track, similarly synced.

I will work through in ordinary mode cutting out bits of at least one camera where the motion is too fast or focus is lost or whatever, to make the eventual multi-cam mode more efficient. So the timeline before entering multi-cam is still fully synced but there are some gaps in the video material.

I work from the start multi-camming say a couple of musical pieces. I will then go back to ordinary mode and make fine adjustments to the cut points by dragging the cut points. This function is really elegant.

I repeat this process working my way through the concert, usually over several sessions, days apart.

The sort of things that can go wrong for no apparent reason:
* One of the camera's material no longer appears in the output tracks 1&2, and no audio is heard over the speakers.
* When restarting halfway through the concert, when I click on one of the small preview pictures to select the camera I wish to use, all the previews jump to show what's at the very front of the video, i.e. at t=0.
* The prog can use a chunk of a track that I've excised (say for a focus problem) in the multi-cam ouptut, despite there being nothing in the source track. (All tracks remain in perfect sync, it just uses material for the multi-cam output that I've told it not to and which it it no longer displays on the source track - very confusing)
* Worst of all, I sometimes find that chunks of already processed work (earlier than where I am now working) have now simply disappeared from the output tracks.

If anyone has experienced and cured any problems in multi-cam mode I'd really appreciate hearing about it.  I imagine I'm doing something for which it is not designed, but not prohibited by the instructions nor prevented by careful software design. Thank you.
