Re: AE arror issue: HELP

AE's trying to tell you that your system doesn't have enough RAM to piece together the composition you've made.

For me, the main problem is that my composition (or some of my nested comps) is too large (I try to stay under 2000 x 2000). If you need to stay huge, sometimes i take the time to "windowpane" a shot (cut 1 big comp up into 2 or 4 sections).

These tricks chop up your project into managable pieces that AE doesn't choke on.

Of course, you could also mess with your image cache/RAM settings under Preferences, or go fill up your system with more RAM...
