Preview to ram slow to start
Lately, when doing a ram preview, my machine will quickly render the first couple of frames. Then, there is a delay of about 30 seconds, and it resumes rendering at the appropriate speed. This is a new system, but early on it didn’t used to do this. I’m using an i7 with 12 gigs ram. Any thoughts on why the delay?

Interesting. Two thoughts:
One, what’s an ideal codec to use? Quicktime? I do often bring in m2v footage. Is there a transcoding program that’s popular?
Second thought: I checked out a project that has no video in it and did a ram preview. The preview doesn’t stall out for the 30 seconds that it does for other projects, but it does hang for a half second about 8-10 frames in. Obviously, that’s not a big deal, but I thought it might give some more insight into what’s going on.

Just a shot in the dark but maybe something is competing with AE. Since you said your comp is new maybe there are updates running in the background.

One possibility:
If you’re being overly aggressive with the use of the Render Multiple Frames Simultaneously multiprocessing feature, starving some of the processes of RAM, then After Effects can take a little time to shut down a few of the processes so that it can keep going.
If you’ve only got 12GB of RAM, you probably shouldn’t be using all of your processor cores in an 8-core system, but instead should leave a few for other applications.

That’s gotta be it. The settings only list 4 cores, but I limited AE to 3 cores and tweaked the ram settings. That seems to fix it. Looks like I’ll futz around with that a bit more. Thanks for the ideas, guys!
