Question

AE freezes temporarily after Preview

Preview works as expected, it caches the timeline and then plays back in real-time. However, after I stop previewing, AE freezes for about 10-60 seconds (it seems to be linked to how complex the comp was). The mouse starts spinning, and if I click on AE it goes to Not Responding. After a period of time, it goes back to normal and I can resume work.

 

I'm finally driven to writing this because the comp I'm working on currently takes about 3-5 minutes to unfreeze AE. So I need a coffee break after every preview - it's really breaking my workflow. I've been experiencing this issue for about 2 years. I believe it started after one of these things; upgrading to CC 2020, upgrading PC to i9-10900K, upgrading GPU to RTX 3070.

 

Primary things I've tried:

Complete Windows reformat.
I just switched cards from a 3070 to a 3080
My Nvidia Studio Drivers are up to date
My CC apps are the most current version
My system drivers are current, including the latest drivers for my motherboard.

 

System:
Windows 10 x64
i9-10900K
RTX 3080
64GB RAM

 

I'll post any other system specs or information if people need to dig deeper.

I believe I solved it! 

I had my After Effects cache syncing to a hard drive but it was 7200rpm HDD. I've never noticed anything in the past and I always thought that would be fine. But it looks like that is what was causing the delay. It's possible the drive is going bad or something too. I switched the cache location to a SSD and now it's much better! I've sinced ordered a NVMe that will be a dedicated cache drive.

Would you trun off the setting of Enable Multi-Frame Rendering and try the preview?

Ah, I should have mentioned this in my main post. I did try this and saw no effect.

Hi kevinharvey,

 

Sorry for your issue.

Are you on a dual monitor setup? Are you using any third-party plug-in that could cause this or font? Are you using any other GPU-intensive program while using After Effects?

Let us know.

 

Thanks,

Nishu

Good questions. I am using a dual monitor setup however my AE is just using one monitor it doesn't span across both.

Sometimes I have Premiere open also. But generally no other intensive programs. This is also a fresh install of windows so it's pretty lean still.

Thanks for getting back. How your secondary monitor is connected to your computer? Can you try using After Effects after disconnecting the secondary monitor from the computer? Do you have Mercury Transmit enabled? If so, try disabling it. Also, what's the version of your GPU driver that's installed? 

Let us know.

 

Thanks,

Nishu

well, at least for the latest versions it could be related to multiframe rendering and cahce consolidation - AE taking too long to shut down the extra render instances. Otherwise I'd strongly suspect a configuration issue with the RTX cards and the display buffers being shuffled around, which of course leaves you with the annoying task of experimenting with the settings in teh NVidia drivers until something works. Outside that there's not much one can say. This is clearly a case where you need to move on to the nerd level and use a tool like Sysinternals' Process Explorer to monitor the various function calls from the program and see which one(s) cause(s) the delay(s) or at least spend some time watching task manager and resource monitor until you see a pattern. This mustn't even be AE, it could be some shietty little driver or tool you are not even aware of...
