Ken Burns Crop sends the program off the rails
How do I fix this?? I've been having this issue with Final Cut Pro for about a week now: attempting to adjust the Ken Burns Crop causes the program to get buggy and lag. First, I can't see my adjustments as the refresh takes several seconds. Then, as I try to adjust the "end" screen, the program becomes completely unresponsive. The only way then is to force quit and relaunch FCP.
Doing anything else doesn't seem to cause any issues. I just ran an update to Sonoma 14.5 (23F79) but this has not helped. My library is on an external drive that still has 1TB free space. It's a complete mystery.
