Activity Forums Adobe After Effects Error when I do a RAM preview

  • Error when I do a RAM preview

    Posted by Dennis Vogel on August 18, 2007 at 1:39 am

    Hi Guys,

    When ever I do a RAM preview with After Effects CS3 I get this error “After Effects error: RAM Preview needs 2 or more frames to playback.” I don’t have this problem with After Effects CS2 (7). Do I need to set something differently? It have done this since day one.

    Thanks,

    Dennis

    I’ve been getting that and other related issues as well. It seems as though CS3 runs out of memory very easily! I have a relatively beefy system–Core 2 Duo, 2 gigs of RAM, decent video card, and I’m not throwing alot at the app.

    Sorry I don’t have an answer for you, but just wanted to chime in and let you know you’re not alone!

    You’ve most likely limited your work area to one frame, so there’s nothing to preview.

    Reset the work area to the region you want to preview.

    No my project is a 30 second DVD menu. I have this problem with any project and none of them are less than 30 seconds in length.

    I just started getting the same error. Found this post because I did a search on it. Anyone from Adobe have any advice? I’ve been running CS3 for a few weeks and today it just started.
    Mac OS 10.4.9
    AE CS3 (8.0.0.298)
    Lots of use of Trapcode Particular and Shine plug-ins

    The first guy was right on. I had this error on just one of my projects but not the others. I changed the work area and it worked right away. The way to test if this is the problem is to select the Composition Menu: Trim to Work Area. This trim your timeline to the currently selected work area (in my case 1 frame). Hit control-z to undo it. Then look for the blue handles below, not above the timeline. Grab on the left side and drag it out to the end of the timeline. This should fix it for you.

    Best of Luck!

    quick clarification – blue handles below the timeline markers at the top

    I’m not sure if Mojo was proposing a work-around to a bug, or clarifying user error, but although this is certainly possible as a user error, there’s something else going on.

    I haven’t tried mojo’s fix. But it’s clearly more than user error.

    That said, I’m responding to both clarify that
    1. Adobe shouldn’t write this off as a noobie user error.
    2. The problem rectified itself when I did a Purge>All (so far), leading me to believe it has something to do with memory.

    Note: I haven’t yet upgraded to X.4.10 and AE 8.0.1 (I’ll do it as soon as I can get a break in projects because I’ve got OpenGL issues as it is currently)

    Hope it helps,

    I got exactly the same error message. The problem is kind of both a bug and a user error. The project comes up, or goes into, a state where the work area is set to 1 frame. So a simple user adjustment fixes it. I’m on the latest version of CS3 with a quad core intel mac and 10.4.10

    I hope this helps.

    I’ve been getting the same error – also working with a lot of Trapcode effects. When I hide the layers using Particular (Trapcode) I can RAM preview with no errors.

    might be a bug in the recent Trapcode CS3 releases?

    That sounds like it’s coming from a different problem. Maybe the layer with the Trapcode effect is set to only display one frame (?).
