Premiere Pro - Using too much memory 100GB+

[Morgan29803041oxel]

Hello,

On the Premiere Pro 2023 version, I am experiencing high memory usage. There's about 3 TB of footage/photos/music in my project...the memory usage will grow to be as much as 100GB. This issue has been replicated onto a new laptop. My previous laptop of 16GB, would crash while working on my project. I haven't experienced a crash yet on the new laptop, but the memory usage is still going very high. Please, let me know if I can provide any other information to help find a solution to this.

Laptop specs - Macbook Pro i7 CPU 32GB RAM M1.

the memory usage will grow to be as much as 100GB.

By @Morgan29803041oxel

If you mean hard drive space, and not memory (RAM), then 100 GB may very well be normal.

[Morgan29803041oxel]

I believe this is referring to RAM? I'm not sure.

[Peru Bob]

Yes, that is RAM.

[Peru Bob]

Try creating a new project and import the old one into it.

[Morgan29803041oxel]

Yes, tried that. Unfortunately, it didn't work. Seems to be stabalizing around 150GB...is this normal?

[Peru Bob]

No, that is not normal.

Hi Morgan,

Sorry for the memory issue. It sounds like what we refer to as a "memory leak." Certainly not normal.

Can you tell us any more about your project? Is it one with a lot of clips in it? What kind of video clips are these? Are they from a camera or a mobile phone? Are they screen captures? About the still images: are they oversized? Have you updated the project across multiple versions? Are there an undue amount of effects applied? Since it's not really normal to see a project in this state, It is hard to diagnose an issue like this without some background about the media and the workflow you used as you worked on the project. Let us know any details you may have and I hope we can help you. 

Thanks,
Kevin

Thank you for reaching out! I answered the questions as best I could.

There's lots of clips in my project, it's an hour long timeline.

As far as types, anything you can think of, .mxf, footage from at least 2010, both phone video/photos to sony FX6 camera, etc.

There are no screen captures as far as I know. The photos are mostly phone photos or downloads from instagram, barely 1080p and some are professional. The project has only been worked on in 2023 version and has been updated to 2023.2. Not a lot of effects applied, some light color correction, few audio filters. Mostly, de-click.

Try this:

Cleared cookies. It worked temporarily, but after a few hours the project is right back to 50+ GB usage.

You mention phone video.  Not sure if it's still an issue, but premiere has had serious issues with variable frame files and afaik, all smartphone video is variable frame rate.  Unfortunately, the problem manifests in unpredictable ways and does not always cause problems. 

Here's how to diagnose and solve/workaround the problem
use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum

and here's a tutorial on how to use handbrake

Thank you Michael, I will try this and let you know the results.

Morgan,

Sorry about this. You may want to subdivide this huge project into several smaller ones using the feature called "Productions." I have done that with my travel videos that span over several years and have thousands of media objects including photos, graphics, video, and audio files. Though it's work to get that done, it may save you problems as you work on the project. I hope the advice helps.

Thanks,
Kevin

Same here. I'm working on a big feature documentary with lots of mixed frame rate source material. It was absolutely fine up until today, but has just startted running out of memory on a 64gb m1 max laptop. And now coming in around 100GB for Premiere. I can't divide this up into smaller projects in productions at this stage and just wondering if anyone had found any other solutions?

Thanks

[Kevin-Monahan]

Hi Al,

I saw your message and I can see that the memory is escalating for your project. If everything was fine until today, how was your project change from the time it was working until it was not? Did you add more media? If so, what kind? Did you update from 23.3 to 23.4? Something seems odd here. With more info, I hope we can help solve your issue.

Thanks,
Kevin

I have the exact same problem. Premiere is using 150GB of Application memory and I keep on getting the notification that I have to close all my applications. I'm on Pr 23.2.0 (Buld 69) and using a 2021 M1 Max Macbook pro with 64BG of Ram.

[Michael Grenadier]

any sources from a smart phone or screen recording?  If so, see my post regarding variable frame rate sources above

[danw84]

No images or smart phone recordings. Mostly just h.264 mp4's and Prores Mov's. It was a large project though with a lot of footage. The entire project and footage was held on my desktop, not sure if that affected anything but I seem to have got it under control for now by doing a media manager on my main sequence and collecting everything over to an external SSD. The memory usage has now droppped down to 2GB.
