user24076: Normally when you have a multicam video (or any video for that matter) in your timeline, you'll see a yellow bar across the entire length of the timeline showing that there is something that will be output in the final video.

I just finished editing a project, closed Premiere, then reopened, and I noticed that parts of the video were black screens. These lined up to those that didn't have yellow bars on top:

How do I get the bars back on top?

user33737: This happened after I applied effects (lumetri color) to one clip of my three cameras in the master timeline, that camera remained in the muticam timeline with yellow over it but wherever cam 2 and 3 were (which had no effects on them) there were holes of no yellow, I fixed this by going the the master timeline clicking on the cam 2 and 3 clips individually and messin with the effects, not really adding any, but moving the temperature and tint bar, for example, as if I was, and then returning it to zero. This restored yellow over all my clips in muticam view, because, it seems, premiere registered me adding effects. Weird.

user24076: Looks like this one was a bug in Premiere. First, I noticed that the yellow bar was only missing for one of the clips that was part of the Multicam video. E.g. I noticed there were multiple "holes" in the timeline, but these only happened whenever the multicam sequence was trying to use "Video1". 
I went into Multicam edit more by right-clicking the Multicam video in the project editor, and choosing Open in Timeline.
Not sure what fixed it, but I toggled both the Toggle Track Output (eye icon) off then on again, and also Disabled and then Enabled the clip in question. This resolved the issue.


user25716: Just wanted to say thanks, Senseful! I moved over a project file and the related video/audio files from my weaker laptop to a stronger desktop for final Media-out-rendering, and I had the exact same issue. Multicam project, and one of the cameras was just black holes instead of video in the final rendering (grrr, still 3 days lost to a bad render). I found this question, and what worked for me was disabling and then enabling all the various clips for one particular video track. Then I had the yellow bars again above everything in the multicam track, which were missing before (same as what you describe).
I don't know what "stib" is talking about - it definitely was an issue for me in the exact same way you described. Hope I don't run into this again but at least next time I'll be sure to make sure those yellow bars are there before pressing the export button!
