    After Effects CS5.5 Ram Preview Issues

    Posted by Randy Rubin on March 21, 2012 at 3:52 pm

    Hi,

    I’m currently having issues with RAM preview in After Effects. It fails to render my entire workspace. I have a solid layer with a paint effect on it that has about 27 brush strokes, with their start/end keyframed. I try to render about 22 seconds worth and it only gets to about 14 seconds.

    This is a new issue that came up yesterday as well. It’s been happening when I duplicate layers into new comps or dup entire comps. This same thing happened when I was trying to render a comp with about 10 illustrator layers with only transform/mask keyframes.

    I’m working on an iMac 3.4 ghz i7 with 16gb of ram. My media cache is at 20gb. I have 3 GB ram reserved for other applications, 1 CPU reserved for other apps, 2GB allocated per bg cpu and 5 Actual CPUs being used.

    Any help much appreciated

    Thanks, I’ve reviewed this section – nothing really answers my question. I typically can RAM preview working spaces much longer than 14 seconds of the same material or the same material + 12 layers beneath it. If I missed something please let me know.

    Thanks,
    Randy

    I think that just answered my question. I turned off multiple processing and was able to watch the entire length of the working space. I assume this solution is only recommended for comps that aren’t processor intensive.

    Would a RAM preview of a 3D comp with lights qualify as ‘processor intensive’?

    Thanks,

    Randy

    [Dave LaRonde] “But since you reviewed the ways to preview, you’re aware that you can shorten the AE Work Area to preview smaller portions of the comp. I think I’d do that instead.”

    Or RAM preview at lower resolution, or RAM preview with skipped frames.

    Personally, I set up Shift-RAM preview at quarter or half res, skipping every other frame. I keep RAM preview at half or full res, every frame.
