After Effects CC won't stop during RAM preview
on Jun 9, 2015 at 8:22:09 pm

I saw a similar post to this for CS5 but there was no resolution.

Basically once my RAM preview stars there is no way to stop it short of force quitting AE. After Effects becomes completely unresponsive about 3 seconds into a RAM preview.

I've tried all the basic stuff:
+Pressing the number pad 0
+Pressing the ESC key
+Turning Caps Lock on and off
+Clicking on random places in AE
+Trying to minimize AE

But AE refuses to respond until the preview is done. I am working on a heavy project, but I've worked on faaar worse in previous versions of AE and never had to deal with this.

Any help is much appreciated!

What is the full version number of your AE CC? Is it 12.2.1.5? 13.2.0.49?
What are your computer specs?
I mean, heck, we don't even know if you're using Mac or Windows!

CC Version 13.2.0.49

Windows 7 Professional
Processor - Intel(R) Xeon(R) CPU E5-1620 0 @ 3.60GHz
RAM - 60GB
System Type - 64bit

I'll admit I'm not great with the hardware aspect of computers. But I thought 60GB was a good amount of RAM for AE...

What are your memory and multiprocessing settings?

I've allotted 54GB of RAM for AE.

I do not have Muliprocessing on...could that be it?

[Eddy Rose] "I've allotted 54GB of RAM for AE."

Allot less.

Seriously. Leave about a quarter of your RAM available to other applications.

But it's already going slow as f@&k! Won't less RAM make it even slower?

[Eddy Rose] "But it's already going slow as molasses! Won't less RAM make it even slower?"

I know it's counterintuitive, but not necessarily! If you are not leaving your OS and other apps enough RAM to work, that will force the OS to swap real RAM out to virtual RAM on your hard disk.

Turn on multiprocessing for faster renders. Note that there's a delay to get MP going, so it's not always desirable for previews. As for your initial preview delay, is it maybe mixing audio? What does the info panel say when you start the preview?

Okay, I've allotted 15 MB to other programs, I think that's helping a lot! But I'm still running into the same issue, one that RAM preview gets going I can't stop it. I'm totally locked out of AE until it's finished :(

"That will force the OS to swap real RAM out to virtual RAM on your hard disk"

Could you explain that like I'm five? I sorta get it, if I don't give my OS enough real RAM (physical memory) it will be forced to mess with my hard disk. Why is that bad?

Could it be because I'm working off a server? This project really isn't that heavy, it's just a few layers of footage. One layer uses Trapcode Shine, one uses Trapcode Starglow, and a few have their levels adjusted. That's it though...

could you turn off every audio and try to ram preview again? Better yet, can you temporarily replace every footage that has audio with a solid?

None of my layers or any of the layers in the precomps I'm using have audio.

WORKAROUND FOUND

Okay, so I have no idea how to fix this issue but I have found a way to work around it. I go to the folder where my project file is located and double click it as if I were opening it. This process seems to "shock" AE out of the RAM preview.

Im having the exact same issue-let me know if anyone ever gives you a real answer to this question.

And Im not working from a server and all my settings are as they should be-as far as I can tell its a bug. It doesn't always do it if I preview in quarter instead of full.

What (exact) version number of AE are you using? 13.2.0? 13.5.0? 13.5.1?
Previews are very different between 13.2 and 13.5 and 13.5.1 fixed a lot of the bugs in the new preview system.

Working off a server might be the problem. I always work locally, especially dealing with footage. If I work with footage off a server, it gets pretty slow. I would work locally first, then save everything back to your server when you are done.
