Hi

I made a video of my problem







The preview goes really slow then stops.

Recently installed windows 7 64 bit running 4 gigs of ram.

Why is the preview going super slow then stopping?

Hi Anthony,

The speed of your Ram Preview is really dependent upon what's happening in
your composition. It's hard to tell from your video exactly what's going
on in your comp but Im guessing it's got a lot of 3D layers and effects applied.
Can you provide some more details on your composition?

4 gigs of Ram is not going to buy you a very long preview. Especially in an HD composition.

Do you have "enable multiple Processors" selected? If so that may be slowing you down as well.
You don't have enough Ram to run more than 1 core at a time. Check out Todd Kopriva's
article on the subject-

I noticed you want to preview the work in Full Res. Try setting your Comp window to 1/2 res or 1/3rd res and then hit 0 for a ram preview - you'll get a much longer clip.

Quick question about RAM preview...I'm new to AE and working on a Mac Pro with the Bluetooth keyboard. Problem is that the Apple Bluetooth keyboard doesn't have a numeric keypad. So...I can't use the 0 key for RAM previews. Can't I use the other 0?

For RAM Preview: there's a button in the preview panel that looks a little similar to a play button. See the following link:

http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103906...

Look under the "Use RAM preview to play video and audio" subhead.

You can also try a Standard Preview:

You can hit the spacebar for a standard preview - that will play the video in the active Composition, Layer, or Footage panel from the current time. However, Standard Preview will not play audio.
