Did you clean the cache files within Premiere Pro preferences or did you manually delete the files? I do both. Within Ae and Pr Preferences, we can Browse for a location for our Cache files. I use a very fast external RAID, and I choose them to go there. Pr is still ignoring the location I select and putting some files in my selected location, and others in my Library>Application Support>Adobe>Common>Media Cache Files folder. Did you change the location of both Media Cache Files and Media Cache Database? Yes, both as I described above. If I happen to launch Pr and my RAID (or just the Cache partition I selected) is off-line, Pr automatically resets the Cache locations to the default path on my boot drive (Library>Application Support>Adobe>Common>Media Cache Files folder). I also have to reset my Cache locations again every time I delete Pr Preferences (which is something I've had to do less and less since Pr 2015 came out. Thanks for that!). Pr is still ignoring the location I select and putting some files in my selected location, and others in my Library>Application Support>Adobe>Common>Media Cache Files folder. Which OS are you on? I'll try to repro this on my machine and see if I get the same result. I'm on 10.11.6 now, but this has been going on for several OS versions, and as far back as Pr CS6. Todd Kopriva, an Ae guy of years past told me that Adobe has this done intentionally, as there is some method to having a shared location. I didn't like it then, and I still don't. Anyway, taking your advice and deleting all the cache files hasn't helped at all. Pr still stops displaying video and/or crashes if I let it play after my RAM meter is showing 100" usage. Do you get a specific error message? If you've a crash log, that would be helpful. Have you installed any third party plugins for Premiere Pro? About your advice not to let my RAM usage get so high, that's not even anything under my control. I meant this: Decrease the amount of RAM Adobe apps are using. Additionally, change the rendering optimization from Performance to Memory. I usually set this to 4 or GB, but the latest versions of Pr and AE, it Defaults to 6, and so I leave it there. I have 32 GB of RAM. I've experimented with toggling between Performance and Memory, and can't tell a difference; but I'm depending on my memory here, too. I haven't noticed a trend, but I'll try your suggestion of using Memory. What are your computer specs? MacPro3,1 - 32G RAM - Nvidia Quadro K5000 GPU (latest CUDA driver 8.0.51 / Mac OSX video driver) - 10.11.6 - Projects, Media and the Caches I select are all on and ATTO SAS RAID 16TB (500MB to 2GBs reads and writes) As a freelance editor, I get a variety of source media types: AVC, H.264, Sony, Canon, RED, Alexa. I haven't tried all these formats on the new build of Pr yet, though. Again, thank you for your reply here. Jim
