First, install the updates.They fix a lot of problems, including a workaround for a memory issue in Mac OS.
Regarding Memory & Multiprocessing settings, start here. But don't bother with that until you've gotten your current issue sorted out. There's no point in trying to use multiprocessing if you're failing to render with only one process.
Thanks for that -- I updated, restarted the computer, but the same thing happens. Tried it with multiprocessing, but the info tab said "Insufficient RAM, Multiprocessing Disabled" It won't let me change
I watched carefully this time: Until frame 324, I'm using 15% of my 8GB RAM, and the Estimated Time kept dropping fast, down to 1 hour 53 minutes. Then at 324, it practically stops: rapidly escalates until it's using 66% of RAM and finally freezes - when I Force Quit, it lists the programming as "not responding".
Open up the secret preferences by going to Preferences and holding down the Shift key and clicking General. It's the bottom tab.
Click Disable Layer Cache and set Purge Every to 5 or 10 frames.
If that doesn't fix it please show us your render settings in the output module and tell us the size of your comp.
Try exporting to any other format (something other than QuickTime) to see if the problem is isolated to QuickTime.
This had an interesting result: the percentage of RAM in use no longer goes through the roof but tops out at 13%. The render does not stop but goes painfully slowly. At 24 hours of render time, I've now gotten to frame 1470 of 8114. Estimated time to completion now reads 109 hours.
As I mentioned before: I'm just rendering a 2D Comp to Quicktime/Photo JPEG Codec with an aspect ratio of 960x540. The comp is simple: a 1.6 MB jpg with a slight scale-up and a Liquify effect for a duration of about 4 minutes 30.
Or does liquify just take this much processing power?
I tried H.264 and got the same result.
