Show Duplicate Frame Markers Slowing complex sequences

[paulejonesy]

There seems to be a bug in recent betas of Prem that will slow timeline navigation to a crawl when 'Show Duplicate Frame Markers' is enabled. This happens to me when the timeline is at a wide zoom and the squence is complex. I have been using MultiCam sequences with multi-track waveform audio files. Interestingly, if I delete the multi-track audio tracks in my sequence the slowness dissappears. I have tried converting the audio to various different formats and the problem persists. The issue is lessened at a narrow timeline zoom. 

I am currently using Version 24.1.0 BETA (Build 38) on an M1 Max MacBook Pro 64GB. This has been happening for the last couple of weeks on every daily build of the beta.

Turning Duplicate Frame Markers off has been a workaround when Captions slow down performance.

Thanks for the reply Stan, but my sequence contains no captions.

Yes, I just meant that there have been other processes in which turning frame markers off has helped.

I couldn't replicate the problem before. Seems like there should be as hint there as to fixing the slow performance.

Same issue. M2 Max, 64gb

I have this issue as well. As soon as I turn on duplicate frames the timeline doesn't play well. Super laggy. (If I am zoomed in to the timeline, the lag goes away.) If I turn off duplicate frames, all returns to zippy speed.

I just discovered after 2 weeks of speculating and troubleshooting that the issue is 'show duplicate markers'. Same exact issue you are describing on the same spec computer, but on Premiere 23.6.2. It's a 1 hour sequence, multicam, lots of edits. Not complex, per se, but certainly long and lots of edits. This is exactly when I need duplicate markers turned on, but at least now I can work in my sequence again. I'm 2 weeks past a review deadline due to this!
