Forums Adobe Premiere Pro Sequences become sluggish

    When I first start working in a project, when I scrub through a sequence it is extremely responsive, with no apparent delay or lag. After about 15min the scrubbing starts to become sluggish, where the playhead has trouble keeping up when I drag it.

    I’ve found that when I simply duplicate the sequence, without making any changes at all, that new sequence scrubs responsively again. After 15min it again becomes sluggish and I can repeat the process to maintain responsiveness. I can also make the performance responsive again by quitting Premiere and opening it again. Obviously neither solution is ideal.

    As for tech specs I am on a 2022 Macbook Pro 16in, M1 Max, 64GB RAM, Mac OS 12.6, latest version of PR. I am editing 4k ProRes footage off of an external SanDisk Extreme Pro SSD connected via USB C (or Thunderbolt? I can’t tell the difference).

    I have the same issue at times. I think it has to do with how Premiere is storing files in the media cache.

    Here’s my workaround so far:

    1. Dump the media cache and do it frequently.

    2. Set up an SSD dedicated to the media cache.

    3. Use proxies and lower playback res.

    4. Close and re-open the project.

    Does anyone else have this problem and/or fixes?

    Same issue here. Unbelievably irritating. Going to go back to 2022 version for my new projects. Completely unusable.

    We have an editor with the same issues. iMac Pro. I’ve done all I can, including a full CC delete and reinstall to no avail. Which makes me wonder about a possibly corrupted user image. But we can’t do anything about that in an enterprise environment (like create a new one on our own). So we plan, at some point, to take it to IT and have them nuke the machine and do a full OS reinstall, etc. And it’s persistent to their machine only. None of our other editors have the issue.

    On repeated edits on the same set of footage, the cache gets fragmented as hell. Dedicate a folder on an free SSD drive for all cache. Delete them frequently. It may take a while to rebuild the cache, but it is worth the wait. Depending upon your CPU / GPU, use proxies and low res playback.
