I just finished editing 2 multicam clips and rendered them (total about 2 hours). Due to an issue with a plugin I rendered out one of the angles separately and replaced it later on. When looking at the final render of one of the multicam clips I noticed that the effect that I had rendered out seperately did not appear in the final render, it had used the old angle without any effects. When playing back the multicam clip in the timeline it appears fine.
So i decided to trash the old angle and rerender part of the timeline. On top of taking a long time it rendered out black video.
Adding the multicam clip to a different timeline, rendering out and the result is the same. However making a copy of the multicam clip and adding that to the timeline and everything is normal. While that is good a new multicam clip means having to re-edit everything.
Relinking files has no effect
Trashing preferences has no effect
Reinstalling FCP X has no effect
It seems that I have a multicam clip that was somehow corrupted, is there a way to correct this?
