Yes, more PP2020 lag issues…
Hello, everyone… I’m having a terrible time with performance using PP 14.5. (27″ iMac, late-2015, running Mojave; 32GB RAM, 2GB AMD Radeon R9 M390 graphics card.) The lagging is worse than ever (and I completely skipped Version 13). I’m running 1280×720 CineForm proxy files based on UHD footage; I’ve dropped the program monitor resolution to 1/4; I’ve tried switching the renderer from Metal to Open CL and back again; I’ve turned off waveforms (I don’t use video thumbnails); I’ve tried possible solutions and tips from multiple “How To Eliminate Lagging” YouTube videos, and the footage still won’t play smoothly (audio does). What’s even newer is that my keyboard controls aren’t always working accurately either – sometimes I’ll press JKL and there’ll be a beat before it starts, and it keeps going after I’ve tried to stop it, either with K or the spacebar. (And, as I’m sure you’ve heard before, NONE of this happened with PP2018, Version 12.)
Am I overlooking ANYTHING? Many thanks…

You have probably already done this, but a good place to start is to dump the cache files manually (delete the cache folders from the user/library/application support/adobe/common) and reset preferences (hold alt + shift when starting the app) to get a “clean start”. Are you having issues after directly linking/importing the proxies instead of linking through the proxy workflow? Your system should have no issues with cineform at lower res. It may also indicate a storage issue, what drives are you using? Can you verify those work at full and reasonable speed? Perhaps try to link to files on another drive as a test measure.

Thank you, Merlin – I didn’t know you responded so quickly. I’ve been using the same proxy workflow for three years – creating them in Media Encoder before creating syncmaps in Tentacle Sync Studio and then importing the footage as XMLs into Premiere, where I attach the proxies. The drives I use are G-Drives, usually 6 to 8 TB, and there’s never more than 5 TB worth of media on them. I have dumped cache files, but did not trash preferences.
So when the lagging problem even happened with a different project that contained 720p Zoom videos, with no proxies and 1/2 resolution, I asked an expert at a computer store here in town, and he wondered if my 2015 iMac was up to the challenge of Adobe’s ever-increasing specs. And it was on the low end of acceptability. So I am writing this on my brand new 2019 iMac, 6-core, 4GB of graphics RAM, 128GB on system memory – and it better have fixed the problem! Thank you so much for the response, and happy Halloween!

Folks, I think the problem is PP2020, 14.5. Yesterday I bought a really powerful new iMac, thinking that my 2015 computer had a problem with Adobe compatibility. I’ve just opened the project, and my timeline is lagging just as badly. Proxies are attached, 1/4 resolution, it just staggers, while the audio plays easily (and it’s not a particularly elaborate timeline). So I tried an experiment – I plugged in a drive with an episode from last year, edited with PP2018 (v.12), with no lagging issues at all. I opened it with 2018, played the timeline and it was perfect. Closed 2018. On the drive, I double-clicked on the project, and by default PP2020 loaded and asked me to rename the project, which I did. And sure enough, when v.14 opened and I played the same timeline that flowed in v.12, it lagged and staggered. It’s not the hardware. It’s not the project. It HAS to be 14.5, and I’ve just spent a LOT of money on a new iMac that I apparently didn’t need.
Any thoughts, or even a “there, there”? Thank you…

Try this. Create a new project, and a new sequence to work on. Import your previous project/sequence, and copy/paste your old timeline onto the new one.

Well, folks, you are not gonna believe this (or maybe you will), but it was all due to a corrupt LUT! For the past two years I’ve been using a CLog LUT from Canon for their C300 MKII camera with no problems. (I used to cut everything using PP2018, v.12, because 2019 gave me lagging issues as well.) Upgrading to PP2020 caused it to start happening again – but when I turned off the adjustment layer with the Canon LUT on it, or removed it entirely, the sequences played smoothly. And as an experiment, I dragged a DIFFERENT LUT from the Lumetri Creative panel – I made it black and white – and it played FINE! I tried one Creative LUT after another and they ALL played – but as soon as I replaced the working LUTs with the Canon one – jerky, lagging video. I even switched the LUTs in the middle of a shot, and as soon as it changed, the video staggered.
I’m not tech-savvy enough to explain how this happened, but needless to say I’ve dumped that LUT entirely. And I’m back in business. I’m grateful for everyone who helped me on this insanely frustrating issue.

I’ve seen major glitches in Pr from corrupted effects (video and audio) and transitions. You did the right thing my not trying the same fix over and over and over. Finding corruptions that cause weird performance are often a matter of search and destroy until you find the culprit.
Who doesn’t love a happy ending?
