I've been trying to animate a little something but whenever I press space or 0 to preview it, it won't stop, it takes a really long time IF it does. I never had this issue before I updated to CC2020, it can't be a media cache or a RAM issue, cause I literally only have like 5 layers of text;; It just keeps looping over and over.
Updating driver....no problems during last 24 hours. But an annoing issue may be related to this is the fact that previewing ...lets say 20" clip in Full HD takes all the available RAM (32 in my case) then it slows down I can not even move mouse. I just bought an 1 TB SSD to move temp folder and video there to improve speed...but nothing. I have to empty cache every 30 minutes or less. Otherwise I'll have to force a close app and loose my job. Too many AE 2020 issues with rotoscoping and now with previewing. If I can not preview I can not work. Older AE versions are sooo much more stable!!
having the same issue. i have noticed less of a probelm when my external monitor is not connected. I am on a 2018 MacBook Pro with a Dell Ultra Sharp monitor connected via the Displaly port of the monitor to USB-C drive of the Mac.
Adobe tools have gotten many stupid stability issues over time. I'd rather have no new features for 2 years but no crashes or other issues that slow down the flow of everything. Gosh!! I've had so many issues with at least 3 apps (Photoshop, XD, AE) in the last few months it's really making me consider moving away and quiting adobe all together.
Temporary solution: Use the Preview panel controls (play button) and don't move your mouse off it. This should allow you to stop it almost immediately.
I found that using spacebar puts me in the loop limbo too.
Reading all these tricks upon how to preview... It looks like an old motorcycle, the one only the owner knows how to start. But this is supposed to be a brand new car. My feeling now is this: there are no more CD installers with a very stable software inside ( I can't imagine all theese issues and a pack of CD's distribution release every month for free after you pay). So we all are betatesters. In this way Adobe can release sooner a new version. Sincerelly fustrating
After my last ram preview error + Alt F4 to force closing AE at 7:45 a.m. I realized there was no Mercury or CUDA proyect setting available: ghosted out.
After second launching CUDA or Mercury transmit is available again....so I choose CUDA and working fine so far (15 minutes). May be the mistake is not recognizing Nvidia card when launching.
I'm having the same problem. I need to use Task Manager to shut down After Effects. I am now essentially out of the "preview" business in AE. I need to render it in Media Encoder to see the results. Can't wait for a fix!
Have any of you tried what was mentioned earlier in this thread? This started happening to me after updating the Nvidia studio driver. Once I downgraded it to the game-ready driver, it has worked fine since. You can also try downgrading to a more previous version if that doesn't work.
Hi Yanna, thanks for letting me know. I'm using a mac, i'm not sure how I could switch any driver from gaming to studio. Is that something that can be done directly in AE?
I'm on macOS Catalina 10.15.16, After Effects 2020 with latest update. Same issue. RAM preview is stuck looping unless I force close even in the simplest comp imaginable.....Essentially making this version of AE completely unusable. Adobe wtf? People have been complaining about this since February. Guess its back to 2019.
