I'm using iMac Pro. When I using Premiere Pro, sometimes it will show that error, I don't know what is it, anyone can help!
I'm having the same issue as well. Could use some help too.
I tried clearing media cache, resetting plugin and preferences with no luck.
If I restart Premiere it goes away for a short time.
I am also having this issue. I have a 2019 Mac pro 24 Core with the 5700x card and 28 gigs ram, running latets PP and latest Big Sur. Premiere is bringing my computer to its knee's. Everything locks up, or runs so slowly as to be unusable.
I have cleared cache, reset pref's multiple times. It works for a short while, and then it will lock up.
Its driving me nuts.
I was getting those messages and something about .mxf importer.
I just downgraded to 15.1 and there have been no 'S error or mxf messages so far.
Update - In addition to downgrading Premiere, I also had to downgrade Media Encoder as well. Version 15.2 Media Encoder had failed encodes when working with 15.1 Premiere. I am hoping this is only a temporary downgrade until the next software update.
I'm working on an iMac Pro running OS Mojave.
Finally, I also downgrade Premiere Pro and Media Encoder to 15.1 as well. It's seem back to normal and no error.
Thank you for your suggestion.
Lifesavers!! Did as you did, and for now at least, its working flawlessly.
I am experiencing this issue as well. do we know if Adobe plans to fix? Do we know the root cause of this?
This has never happened to me before until today and I havent done anything differently to my knowledge.
2019 Mac pro (16 core) user running Big Sur here with similar issues.
All builds since 15.2 have been so unstable they are unusable, especially in projects with a large variety of media types (MXF, .R3D, and prores for example).
Please fix this :).
Same problem here. Until now, I've been working around it by saving my project with a new version name, or changing file path names and relinking footage, but it just crashed so hard my computer auto-rebooted.
Is there a way to roll back project file versions? I'm mid-edit on a version 15.4 project file, and I need to finish without losing progress.
I'm on a imac pro running Mojave. I recently upgraded to 15.4 and had an issue where it had trouble rendering previews. The error said something about trying to duplicate a frame or couldn't re-create a frame. I wasn't sure if it was a problem with my project or the new version so I dropped back to 15.1 and the problem did not occur in the older version.
I think you should be able to open your project in 15.1 since it is only a .X version and not a version created in say version 14.
Thanks for the reply. You're right about .X versions, rollback worked like a charm.
Worth noting, I only had problems with one project that contains BlackMagic MOV footage (crashing, save errors, effect errors, playback only working on audio). All my RED edits ran fine on 15.4.
Are you on a mac or pc? If on mac, what OS?
My project had a combination of .mxf, .mp4, .mov files.
I can't figure out why the newer versions aren't working. I don't normally have issues with the upgrades and I wait until the X.1, X.2 versions come out from Adobe before I update.
Yes, I'm on MacOS Catelina 10.15.7.
I haven't had issues updating Adobe until now, and can't update my OS. Wondering if the M1 support is part of the problem when I'm not on an M1 system... but no idea how to test that.
I discovered that Ae 18.4 dynamic link isn't working with Premiere 15.1, so for now I'll keep jumping between Premiere/ME versions until my project is complete.
