Question

.pek files generated daily

Hi,

I have a problem with Premiere and I haven’t been to find a solution for it. I’m working on a Mac Studio M4 Max, connected to a Ugreen DXP4800 Plus via Network. Working on Tahoe at the moment, but the same issue occurred before on Sequoia. Working on Premiere 26.2.2 but the problem occurred with other versions of Premiere 26 as well.

Every day I open my project, Premiere will generate new .pek files for clips that were already generated before. The old ones remain in the folder where they were originally created and new ones are created in a new folder with the date.

I have tried changing Media Caché location, I re-setted the settings, I made sure the NTP of my NAS and computer match exactly. I actually completed formatted the computer and installed everything from scratch, and the problem remained. I don’t have any plugin.

I have checked the FileID and other metadata in the files on my NAS and nothing changes, so I don’t think the issue is with the NAS itself. I have another computer (exactly same specs) connected to the network in the exact way and that was doesn’t have any issues, it’s just this one location.

I know that there are ways to tell premiere to stop creating wavelengths, etc. — but that’s not a solution for me. I’m working on a long form documentary with clips being imported daily, and I will continue in the project for another 6 months, so I need to solve the issue.

Any suggestions? Potential things that could be causing the problem and I haven’t thought about yet?

It’s incredibly frustrating and unsustainable long term.

 

Thank you.

    I have had those issues on Windows as well and something i noticed that increases the risk of ending up in a loop of re-creating .pek files are to start working with media before the .pek files have been created.

    I solved it by closing all Adobe apps and then manually deleted the Media Cache Files and the Media Cache Database. Then i opened the project and did nothing in Premiere until all files were created.

    To find the files location: Go to Preferences > Media Cache

    I recommend having those files on an internal drive rather than an external drive/network/NAS/DAS.

    Hi. The Media Cache files are in the internal drive (tried default location from premiere and a different one I set up manually, no difference).

    I have also done as you suggested, just creating all the .pek files before doing anything else. Sadly, none of those things worked 😔

    Did you remove the Media Cahce and the Media Cache Database at the same time or only the Media Cache?
