I'm experiencing something similar, though it's with all multi-processing. I've tried exporting with both Quicktime (ProRes, Animation, etc) and with image sequences. No dice either way.
I get an error dialog: Rendering Error: An Output module failed. The file may be damaged or corrupted. (-1610153464)".
And my Console is full of these errors:
"7/16/13 10:06:37.116 AM After Effects[590]: objc[590]: Object 0x141202d90 of class NSRunningApplication autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug"
I've tried cleaning out codecs and whatnot, with no joy. I'm on the latest version of After Effects CC (12.0.1), and it seems the error was introduced with this version. Thoughts?
