Do not install Apple Monterey 12.3 update. It causes dropped frames on the Program window (Right Screen that plays timeline). Video will drop frames no matter what resolution or quality setting or even proxies. There was no solution that I could find including any Premiere settings changes, timeline changes, even playing proxy clips that were low res dragged onto a new seqnence with that proxy settings would not play smoothly.
Adobe, please be advised and I hope this gets addressed asap.
Hey there, Viet5F95, I hope you are well. I am not seeing this performance issue. Can you give us your complete system specs and more info about your media? Which camera did it come from? Have you tried deleting the media cache with all projects closed? Let us know.
