Premiere Pro Mac Memory Issue

[zoe_6381]

Hello, I'm an editor for a commercial company, and I've recently had a major memory issue with Premiere Pro Ver 25.5 on my Mac computer. I thought I had too much media on my project file when a Memory Limit pop-up appeared on my computer, and it enlisted that my project file was 108 GB. I tried making a new premiere project folder and copying over only the intended pieces of media, but the pop up came up again an hour later, even though the folder says the project is 7 MB large compared to the prior 12 MB large file. I tried clearing old media cache and allocation more RAM to Premiere (12/18 GB to 14/18 GB), and nothing changed. I didn't add any plug ins or anything that'd add memory to the project file.  I've tried most google suggestions, but nothings changes, and I'm trying to avoid getting a larger processor, is there anything else I can do to fix this?

Hi Zoe,

The size of a project file on disk, is distinct from the amount of RAM needed to load that project into memory. 

What did the pop up you saw, say? 

What memory usage setting are you currently using? 

Have you always encountered problems like this, on this editing system? If not...what changed about your system?

[zoe_6381]

The Pop-Up I saw was force-quit applications, from my Macbook, and it said my system ran out of memry, and that Premiere was taking up a little over 108 GB, and I only had two other applications open. This happened for the first time and rather suddenly, and I have premiere set to work with 14 Gb of the 18GB of available RAM on my computer, and when I checked how much of my storage was being used, it said Premiere was only using 5 GB, so I'm very confused.

Good details, thanks!

The amount of disk storage necessary to hold PPro, (that 5gb number) is completely unrelated to the amount of RAM used by PPro (that 108gb number). 

What were you doing in PPro, right before the force-quit dialog appeared? Does PPro use all your memory, every time you run it, or only when performing certain tasks?

[zoe_6381]

Ever since I started cutting and putting footage in different tracks for selects is when this started happening, but it's only happened during footage with audio, not with B-roll I've worked on previously.

More good clues!

Do you have a piece of media which, when added to a sequence, reliably makes PPro eat all available memory?

If so...can we have it? [I can provide private upload space, if desired.]

[zoe_6381]

Possibly, I have multiple synced sequences, each sequence with two videos and multiple audio channels, but I'm unsure if I'm allowed to share since the media and the project I'm working on is private. My bosses are on set for the day, I don't know the soonest I can reach them.

[zoe_6381]

I got approval to share a sequence, if you can provide a private upload space, that'd be great!

[Bruce Bullis]

I DM'd you the link. 

Ideal = A project containing that sequence and its constituent media, as well as steps we can follow which reliably cause PPro to eat all system memory.

[zoe_6381]

Ok, I just sent over the project and the media piece for it, it is one of the smallest pieces of sequence-media I have for the overall project, but I also have to weigh proprietary info. If you want a bigger file to test, let me know.

[Bruce Bullis]

If what you've provided repros the issue, we're all set! 

[Bruce Bullis]

I got the .prproj and an .mp4 file, thanks!

Nothing I've tried has caused any problems, on Mac or Win, in official or beta PPro builds. 

What steps can I follow, to see what you're seeing?
