Activity Forums Adobe After Effects RAM Preview suddenly delayed

  • RAM Preview suddenly delayed

    Posted by Justin Madden on January 16, 2008 at 6:15 pm

    I’m no expert, but have been working comfortably in AE CS3 with no technical problems, until now: RAM Preview is all of the sudden incredibly delayed! I’ve purged, rebooted, tried different comp settings, different open GL previews, and it’s still delayed. I have 4GB RAM configured properly on Intel MacPro, and I know it’s not the machine. Working mostly with PSD and large JPEG stills. I’m guessing it has to do with both color management and pixel aspect ratio. Any suggestions greatly appreciated.

    Thanks Dave, yes, all of those descriptions of “delayed” apply in my case.
    No 3D, no motion blur, no frame blending; only one or two basic effects per layer, and in one case, there are only two layers! Stills are big, but not that big! There also 8-bit, RGB, 72 dpi.
    Even at half res and 50%, RAM Preview is just as delayed!

    and very important! Sound!
    If you got sound in your comp from the footage or simply a file, it is delayed.

    After Effects first does “Ram Previewing” the sound before it starts even render a frame.

    You can change the duration of the sound preview in the AE settings, so it only “renders” a few seconds of sound and doesnt take so long to render it all. BTW: i think the its preset to 15sek

    Did you try switching off audio for the preview? (shot in the CS3 dark)

    If you have multiprocessing on, try turning it off and see how that works for you. Also, it’s highly recommended to avoid large layer sizes. Of course the size you can get away with will depend on how many/what sort of effects you have applied to the layer. Time based effects like Echo, for example, will eat your available image cache up incredibly quickly and this phenomenon increases dramatically as the layer size increases.

    WOW! Thanks your responses! Multiprocessing was the culprit in this case. I really appreciate your help! Now it’s back to work! Thanks again everybody!
