Thanks for the speedy reply and sorry, should have specified: I'm still on CC 2018. I've been too busy to risk upsetting the apple cart by installing anything new. I guess I'll try 2019 then, now that you've reminded me of the obvious - not holding my breath but what have I got to lose at this point? Edit: Well, I installed CC 2019, created a fresh new project, imported two CRM clips and created a sequence from one of them. The same deal - incredibly choppy playback at 1/16(!) resolution. Edit 2: I also installed the free version of Resolve, and with what little I could do with it, it seemed to almost completely eradicate the problem: almost flawless playback at full resolution, with some quick color correction applied. So as far as processing power is concerned, my rig can easily handle it, as expected. Something in Premiere / its interaction with my system seems to be messed up. Edit 3: Well, CC 2019 did bring with it the ability to create proxies out of the CRM files. I think my existing version of Media Encoder had some problem with it, but now it seems I can create DNxHD-proxies and based on a quick test they work smoothly as ever. Takes a couple of hours, but at least this would get me back to editing instead of gnashing teeth.
