Multi Cam problems
I used to be able to do this but something has changed and I can't make it work. Any help would be appreciated - I'm tearing my hair out.
I use two GoPros to record my cover band. The GoPros do about 18 minutes before they do a save, which creates a file. So if I record a two hour gig, I'll have 6 or 7 files from each GoPro. No problem, Adobe aligns the first clip from each GoPro using the audio. I drag the other files to the timeline in the right order and I have the whole two hour show. picture follows:

I create a bin, copy all those files to it, select them all (14 of them), right click and select create multicam source sequence and I get this mess - i.e. not one multicam sequence but 7. they're all just over 18 minutes long.

I'd butt them up end to end but it doesn't work that way. The audio gets chopped off each one at the end. Picture follows

What in the world have I selected/deselected by mistake or what am I doing wrong? I've made probably a 100 of these videos using the exact same procedure and now I can't make it work.
Like I said, tearing my hair out. Windows 10, 64 bit, plenty of horsepower.
