Hey all,

We are a 12 people team with the same setup:

Z640

Intel® Xeon® Processor E5-4620 v4

64 gb ram

System Pcie SSD ( read 1200mb Write 1800mb ) + cache ssd( 550mb both ways)  both 512gb

Titan X pascal Or Quadro m5000

After effects 2017 14.2.1

Windows 10 pro

Dell 4k displays.

The issue is that while working on a project (doesn't matter what kind of project), it can be 10 sec or 30 min into working and then the ram preview stops working without any reason.

you press the Ram preview, it looks as if it loads it into memory and then it just doesn't play. in the info panel it say its playing real-time but it doesn't move from the current frame.

This issues keeps happening even after a purg all.

the only way to solve it is exiting after effects and reopening it.

Is it a bug ? any suggestions ?

That sounds strange. Those monitors wouldn't be P2715Q would they? Those monitors caused an issue when the multi stream transport option was enabled. Disabling MST got previews working as expected.

Hey,

the monitor is an HP Z32x. but it happens on dell as well.

Talked with support and they told me something corrupts the cache and told me to remove all plugins, and delete all cache. and give it a go.

i can't keep on doing it since i need the plugins for work.

You can do it as a troubleshooting step though. If it still has the problem without your plugins, you'll know they're not the problem. If it stops, great! Then we just narrow down which one it is, by installing some of your plugins and testing until you find the one causing the problem.

Thank GOD I found a thread addressing this. This is driving me absolutely crazy. The only solution is shutting down AE and firing it up again to only work for 10 minutes, sometimes more then bam, same issue. I would LOVE some advice on this.

I'm still having this issue.  It happens more often with bigger projects (Like 3 MBs) than it does with brand new projects.  I'm running AE 2020 on a Mac by the way

Hi!
I think I found a solution. If you change audio hardware output device it starts working again.

Thank you. This worked for me. Still annoying, but not as annoying as a restart!

This fixes it, thank you! This is where Adobe needs to start looking. I plug and unplug my headphones a lot during the day, and this could be part of the issue, I just don't know why one thing would affect the other.

What kind of Footage you are working? 4K footage? 8K? 16bpc? or maybe 32bps? It's not the same to work with a clips with 8bpc than 32bpc. Your issue could be in this way.

I'm still having this problem. The preview skips back one frame and then holds. Requires a restart to fix. I heard that this was somehow related to the audio settings not being set correctly ie: plugging headphones in or connecting via bluetooth, when the settings in AE aren't set for that.
