Kevin –
I use Ppro multicam all the time and do not have this problem, so there definitely should be a fix for you.
Questions:
1) Does this happen on Video 1 as well? What about other video tracks ?
2) Is this happening only with Lumetri or whenever you do anything with the effects panel ?
3) How did you create the multicam sequence – using Ppro’s “Create Multicam” effect, using a third party like Plural Eye’s, or manually within Ppro ?
4) Since this started to be a problem for you, have you ever done a “fresh install” of new versions of Ppro or always installed over the old version?
Let me know and hopefully we should come up with a solution. This is not a universal software bug, and it should not be happening to you.
