I saw there are a few posts on this topic already, but I checked those and it didn't help me.
For the last few weeks, I've been seeing that red sign saying "error retrieving frame at..." pop up pretty often, that is, every single time I'm using Premiere. It doesn't immediately freeze, but once I see that, I know it will soon. Weird thing is, it doesn't freeze completely, I can still close panels, if I hit 'play' nothing moves at all but I do hear the sound working fine. So, the last two weeks have been a complete nightmare. I have made next to no progress at all. Every single time I open this program, it will freeze, after just a little bit of editing. Sometimes it freezes after an hour, sometimes, I'm not even able to make one single edit. I've been thinking of just exporting whatever I have and moving the whole project to DaVinci Resolve (since I'll be color grading on it anyway). Only reason I haven't done this is cause I have a co-editor on the same premiere project. I should mention, I'm having this same problem with another project. And what drives me nuts is that I haven't changed anything substantial in the project (at least not that I'm aware of, obviously). I'm still editing with the same footage as before and I didn't have this problem before. The only difference I can think of is that I've added some short sound clips (sound FX), in .wav or .mp3. I tried switching CUDA and Software only. This project doesn't even have mixed footage, it's all Red camera footage and I'm editing with .mov-proxys, not even with .r3d files (the .mov proxy files are created automatically by the camera alongside the .r3d-files). And again, up until a few weeks ago, I'd never had this problem.
Adobe Premiere Pro v14.0, version 14.0.1
Intel Core i7 7500U CPU @ 2.70GHz 2.90GHz
Windows 10 Home, version 1903
working on external harddrive G-drive 10TB (around 40% still available space)
I'm not using any third party plugins (at least that I'm aware of, I haven't installed anything)
well, I have the same problem but I think I already found the solution. In my opinion, the Premiere Pro are having issues like that bcs of your driver version update. Few weeks ago I've update my intel driver to the newest version. Then I opened premiere pro for the first time on this updated driver and it shows error like that (error retrievin frame...). But then I choose to roll back my intel driver version to the previous version (you can do this at display adapter option on device manager). After that, everything back to normal.
