Insert is hit and miss, I can see it perfectly fine in Mocha… all is tracked, but for some reason it does not appear on the timeline. When this happens I typically have to create a new project & render export from there, because copying the clips to new sequences, then tracking from scratch & adding the insert again does not fix this issue. This has been necessary at twice in one project.
Sometimes the insert becomes invisible inside mocha as well; it typically disappears after adding a new layer… then I cannot see it in the timeline either. It doesn’t matter what I do, making a new sequence and copying the clip doesn’t work, closing premiere doesn’t do it… rendering doesn’t do it, I have to make a new project and start from scratch to make the insert appear again. Export render & bring it into the final.
