AE CS6 Renders Stop after 325 frames - or nearly: they abruptly start slowing down to 1 frame every 30 seconds until they hit a standstill, as the amount of RAM in use starts climbing suddenly until it reaches around 67%, at which point it is dead.
I'm on AE CS6 Version 11.0, freshly downloaded from the Cloud.
I am on a MacBook Pro 5,3 running Mac OSX Lion 10.7.5 with a 3.06 GHz IntelCore 2 Duo processor and an NVidia GeForce 9400M 256MB Card.
I've maxed out the RAM at 8 GB. I'm using Quicktime Player 7.6.6 (the most up to date).
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 (interestingly, the render stop occurs about 15 seconds before the Liquify effect starts.)
I've tried this with "Render Multiple Frames Simultaneously" on and off with no difference. However, when it's on, Installed CPUs reads 2 and Reserved for other apps reads 0 and AE will not let me change it. Also, Ram Allocation per Background CPU has been tried at everything from 1 GB to 3 GB. Actual CPUs used is set to 0, and I cannot change it either.
I have no other apps open during rendering. And there can't be a bus issue, since the AE project, the source jpg and the output location are all in the Documents folder on my hard drive. I'm at a loss. Any ideas or suggestions?
Thanks
