Poor Multicam Performance with Premiere Pro 23.2

[evanlparker]

PP 23.2 is still struggling with multicam editing. 23.0 worked well with 3 streams of 4K footage. 23.2 is hanging, crashing, and struggling with 2 streams of 1080/60. After a few camera changes the system will play back smoothly, but the playhead and audio meters start to jutter and freeze, and changing the active camera can take 1-5 seconds (foricing each edit to be manaully adjusted). After 20 or so camera changes PP continues to playback smoothly, but the interface freezes. I will play video smoothly for 30+ minutes while the program is unresponsive.

I have emptied the cache, reset preferences, disabled audio input, and none of these have made a difference. This project uses only about 40% of CPU/GPU resources, so it is not a system peformance issue.

Restarting PP solves the issue for the first few camera cuts, then the entire process repeats.

As a test I just installed PP 22.6.4 and multi-cam works without issues. Fortunately I was able to split the project and not lose a lot of work.

I was experiencing the same issue in 23.3 on Windows 10. I downgraded to 23.1 and seems to be working so far. I can't go to 23.3 because I experienced a separate bug with exporting. So hopefully 23.4 will be better.
