Out of Memory Message

I'm rendering HDV 1080i60 footage out of After Effects onto an external drive (197GB available) and somewhere along the line After Effects stops the render and gives "Out of Memory" message. Project is 24 layers deep, 13 layers of video (1 video at any given time), 10 layers of stills (2-4 at any given time), top layer is a mask (.psd file).
I'm running 3.2Ghz 8-core, 10Gb RAM. The 'memory & cache' is default 120% of 3.0GB and 60%. How do I keep the message from coming up???

This topic has been discussed many, Many, MANY times here on the COW. Do a search on this forum for terms like "secret preferences", "purge" and "cache".

[Aaron Leong]"HDV 1080i60 footage"
Is your source footage HDV? I'd recommend transcoding to a different codec (HDV uses MPEG-2 compression, and AE doesn't like that so much).
Other than that, pre-render anything you can get away with, check the 'secret preferences' as Dave suggests, enable the disk cache and if you have multiprocessing disabled, try enabling that (I don't think it will help the problem, but things should move faster).
Does AE fail at pretty much the same time in the render every time? I would guess that it is. In that case AE is having trouble rendering one particular layer in your composition that may be effects heavy, the nature of AE's renderer is such that if AE can render the most RAM intensive layer in your composition without any trouble then it should be able to render the entire composition without trouble (this can be complicated when you have 3D shadows, since these contribute to memory requirements significantly and only appear when multiple layers 'interact' with each other).

My source footage is HDV. I'll try the secret preferences. And AE stops at different times. Once it stopped at a couple hundred frames, another it got to 5000 and froze. I had to force quit. Thank you for all of your help.

Don't bother. Your problem lies in your footage.
You have to convert it to a quicktime movie, perhaps using the animation or photo jpeg codecs. Conversion to any flavor of mpeg or h.264 is futile: don't do it.

Okay, for those that are still reading this, I talked with Adobe, and After Effects 7.0 is not able to work with intel based macs which is why it can only render projects up to a certain length. Sorry for the post, just thought it might be easier to find an answer here or maybe someone here found a work around.
