getting a full RAM preview
Sometimes, my RAM preview will just start playing half way through although it has not completed the entire Preview.
Is it just running out of memory? Is there some setting I’m missing?
I’m previewing a 30 sec SD project at half res.
Dual 2.8, 4GB RAM
Thanks.

It sounds as if you’re out of RAM. Check Activity Monitor (Mac) or Task Manager (Win).
Edit>Purge image caches every now and then.
Consider previewing every other frame.

that would be normal when ae runs out of memory for the ram preview.
you may be able to render more if you hit the spacebar for previews… this will render the preivew to disk, however, play back may not be in realtime depending on the data rate of your dirve and the data rate of the file (high frame rates and large frame sizes can greatly effect the data rate needed to play the preview).
alternately, you may rather reduce the reslution and magnification on the the preview or even the frame rate of the preview in the time controls, this will allow you to fit more of your preview in the ram available.

as steve mentioned, in addition to altering the frame rate, you can set the preview to skip frames in the time controls panel… and that’s probably a bit easier than calculating a new frame rate….

okay, thanks. I’ll try previewing every other frame.

I never thought of reducing the comp window size – does this really work? I’m still getting a full res preivew out of my decklink card to view previews, so this shouldn’t be affected should it?

I reduce the comp window size all the time Jimmybee.

Sorry, that’s what I meant. In addition to previewing at half res, I also decrease the comp window so that it looks better.

This has been recommended practice for a while, as it helped RAM preview work more efficiently. Or faster. Like I know.
It may not be necessary nowadays, as this was recommended when RAM preview first came out in … version 4.1?
Anyway, try it, see if there’s any difference.

It seems that AE was just acting up. I mean, all of your suggestions will surely help; but I just shut down the system for awhile, came back, and everything was working alot better.
It was kind of odd being that I had already restarted the computer once before with no improvement.
Anyway, I guess it just needed some personal time.
Thanks for all of your advice.

Don’t forget to swing the bloody chicken around your head three times. 🙂 You’d think we were done with the computer voodoo, but it’s still a viable option in many cases.
