S-l-o-w RAM Previews
Hopefully someone wiser than me has a possible solution to this problem. We have an Intel Power Mac, Dual 2.8GHz Quad Core, 10 GB RAM, OSX 10.5.8. Running After Effects CS4 and it simply cannot play back any RAM preview in real time. Even a simple one-second 720×480 29.97fps comp of a square solid moving around the corners nets a playback of about 8 fps, even at 50% size and half resolution. I’ve tried restarting, rebooting, trashing the prefs. Playback is set to Computer Monitor Only, Adaptive Resolution is set to 1/4. AE is recognizing 8 cores, 10GB of RAM installed and appears to be taking the 3.0GB max.
A co-worker just told me that they’ve never had a realtime RAM preview on this machine, so it’s apparently not a new development. Anyone have any suggestions for a solution? I’m willing to consider anything up to and including voodoo at this point.

Yup. Zero on the numeric keypad. Shift-zero to get every-other-frame RAM previews, which doesn’t help a bit.

Just throwing this out there. Are you running any other programs while AE is open. I know I have trouble when I run Illustrator or anything really.
When anything is competing with AE, AE seems to get a lil buggy.

it turns out it was an aja plugin that seemed to be interfering with both ram previews and processing/performance (despite video preview being set to computer only).
once the aja plugins were uninstalled it worked fine (of course all kinds of other things were done in the process of figuring that out, so it could have been a combination of changing slot assignments, updating software, drivers and removing those plugins).

The AJA issue is becoming common. I had a friend deal with it on his Mac and at work we had an issue on both of our CS4 AJA Windows Vista machines.
Removal of the AJA for AE fixed the problem on all of the systems. AJA’s put out some updates since we had the issue, so maybe that’ll fix it…
