    I keep running into this error message while trying to ram preview. I’ve never had a problem like this before on this computer.

    After effects error: Ram preview needs 2 or more frames to playback.

    The computer is a Dell optiplex…3.2Gig, 1 gig ram. Plenty of juice for what I’m trying to do

    The comp is not complicated by any means. Simple camera move on a couple of objects. I’ve turned off some of the effects like mesh warp…error message still comes back.

    I’ve played with the comps worskspace…trying to preview it in different places…No dice.

    I’ve brought the project over to another computer…same problem.

    help!!!!

    Your work area is confined to one frame.

    Move the current time indicator(playhead) to where you want your RAM preview to start and press ‘b’ then move the playhead where you want it to end and press ‘n’.

    Your RAM preview should work now.

    This is not the problem. I’ve tried previewing different parts of the work area with the ‘b’ and ‘n’ keys. No luck…same error message.

    Check if your project uses certain effects. Toggle them on and off selectively until you find the culprit. Also if you are using audio you can run into the problem you describe, so check that, too.

    If you’re on 6.5, download and install the 6.5.1 upgrade from Adobe. It should help.

    I’ve downloaded the 6.5 update…didn’t solve it.

    But it seems a still layer(2040 X2367 2.3 mb) I had mesh warp on is is possibly the culprit. Once I took the effect off, the preview worked again. Anyone know why meshwarp (a pretty standard effect) would give me so much trouble?

    I had it and it turned out to be a memory problem. Check your available memory – maybe increase the size of your cache – purge all… Just a thought.
