I tried to move some visemes in the timeline to tweak my lip sync. They won't move and I can't swap them out for other mouths.
Sounds like a bug. You should be able to:
1. Drag on their edges to shorten or extend them.
2. Right-click them to swap out.
If this isn't happening, that sounds like a bug - can you post your computer specs and maybe a video or screenshot of what you're seeing?
