Multicam outputs only black
I have a 6-camera multicam sequence which is behaving in a very unpredictable way. Random segments of the video of outputting only total blackness. Looking at the multi-cam view, I see all 6 cameras on the left, and can see footage being output on the camera that I've chosen to be currently active. But the output preview on the right is totally black. Switching to composite video view still only gives a black screen, and doing a preview render still gives the same result. I can switch the segment of the multicam sequence to a different clip, and then it'll be fine, but then I switch back to the camera I want, and it's black again. I've tinkered around in the underlying sequence to make sure there's no effects or other settings there that would cause the video not to display but can't find anything that should effect it.
This is specifically affecting two out of my six camera angles on this project. At the time when I was initially editing this multicam sequence, it all worked fine, and I can't think of anything that I changed that would have caused it to suddenly stop working. I have noticed that if I hit play, and then click again on the already chosen clip (creating a split in the multicam sequence on the timeline, but not changing camera angles), it'll suddenly start giving me output on the preview monitor again as expected. But then if I hit pause and play again, then we're still right back to the same problem again - just black output. Which, to me, seems to indicate that this is a bug of some sort.
I'm using Adobe Premiere Pro CC 2017 on a MacBook Pro running macOS 10.12.6.
Here's some screenshots:
You can see the black thumbnails anywhere that MC4 or MC6 is chosen:
Here we are on MC4 with black output on the right:
Any suggestions?
