Premiere Pro 2024 - poor playback (M2 Ultra Studio)

Of course people post here with the issues. But, comparatively ... there haven't been many bug/performance posts like we had with every major version release from 2015 on through about 2022. We'd have what's now an entire day's worth of new posts come in per hour back then.

Across the several million daily users, the general performance seems very good. For some users, due to apparently things either in their system or something, it sucks. I've  been on  the short end with sucky performance myself, and had to wait up to six months before I could run the new version. So you do have my sympathy.

Further ... I work for/with/teach pro colorists, mostly based in Resolve or Baselight. I work in Resolve daily, and participate on both the LGG colorists forums and the BM forums. The number of bug/performance posts "over there" has risen dramatically since BM has tried to copy Adobe's goal of being one app/system for all workflows, media, and hardware.

I do know that a number of Mac based editors have posted that 2024 was slow on their rigs, but in going through the OS security and permissions settings, suddenly 2024 was flying on their machine.

So ... hope you can figure out what's  the problem there. And it's good to have multiple options for everything ... 

Any large projects like the OP lists should be done in Productions mode, never stand-alone projects.

Production is designed  to work with massive projects without slowdowns, duplications, all that crud. It's a bit different at first, but ... it was built for handling that workload.

The old single-project "stand-alone" process can't.

I've been trying to downgrade but i dont know how?? Everywhere I look, it sends me to the Elements version. 

Same issue. Premiere Pro 2024 can't even play in timeline a 720 proxy at 1/8 resolution. When I downgrade to Premiere 2023 I can play the same footage without proxys at complete resolution. Premiere Pro promises 5x speed in timeline and delivers 10x slowers speed. As always, Premiere update is an update to a worst Premiere than the previous one

Try and go back to 2022 vsn. That's the last one the worked properly. Keep away from 2023, that's not good for your mental health.

I am having the same issues too! I am on PC. Fortunately, I didn't delete Premiere Pro 2023 so I am working off of 2023. Which it works just fine without any of the lags or crashes that I've experience with 2024. Although, Premiere Pro 2024 works with the Macs at my college. 

I'm glad I'm not the only one with this issue and that there's many of us. I hope they fix these issues soon. 

It just sucks, I am infuriated too. My project is even quite smaller in volume on top of that. It not only freezes, it freezes THE ENTIRE COMPUTER. (Macbook Pro M1 Max 64 GB Ram, 4 TB Internal Memory)

It's most likely the C70 and R5 .mxf files. We have the same issue right now and transcoding all the mxf into proress 422 fixed it for us. It's a pain but works for us until Adobe fixes it. Using proxies helps a little, but just having any canon .mxf files in your bin will cause issues, sometimes even if it's not on that timeline. 

It has obviously been checked by the whole team.

try to set the video previews from sequence settings to QuickTime rather than H.264

same for proxies (better go for QuickTime/Cineform proxies)
