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:
I faced a very similar problem just now, with the difference that I couldn't get output video from the affected tracks no matter what I did in the timeline. I found a fix that workd for me. I hope it will work for you.In the original sequence from which you made your multicam:1. Go to the first affected track in your timeline;2. Highlight one video file or nested sequence (in my case, each track contained only one video file or nested sequence each)3. Right click > select Show in Project. This w...
So I just came across this same bug in 2021, and what fixed it for me was disabling all the clips in the multi-cam sync'd sequence-- and then re-enabling them. After doing that it not only fixed the issue in my current saved project file-- but also all the backup project files I had that had the same problem. I have no idea what the deal is with that bug but I hope it gets fixed-- because that was terrifying.
