Since the latest upgrade (MacOS 13.3.1 (a)) (Premiere Pro 23.4.0 (build 56)), I have had two problems.
The first is that some segments in my timeline go black. I am unsure what triggers this, but when working on one segment, I go back a few segments to play and review how it's all pieced together; some segments have gone black. To get them back, I click the eye icon to toggle visibility off and on until they reappear.
The worst, however, is that whole video tracks with all their sequences go black when exporting. This situation caused some embarrassment as I previously trusted PP to "just work," I uploaded some work to Frame.io only to have clients complain about blacked-out segments. However, I have learned to recognize when this happens, as the export preview goes black when I click the export button. Seeing this allows me to cancel, fix and reexport at least.
The second issue is that changes to transcription are a total failure. I work with two tracks of video and two tracks of audio. The new transcription ignores the second audio track. The live editing doesn't work at all (as in on too many levels to describe here). I have worked around it by copying and pasting segments, creating new transcripts and captions for missing parts, then copying and pasting back. Honestly, I am limping by trying to get my work done, so I am not entirely sure of the steps I take to make things work.
So I have gone from totally trusting Premiere to "just work" to constantly having my workflow borked and interrupted.
I plan to roll back versions because I can't find any posts from others with these issues, but I wanted to speak up first.
