I am trying to Preview the Composition I am working on. The Composition is made up of several compositions and a fair amount of expressions.
When I try to Preview it, it slowly runs through for about a minute (thus turning from blue to green) before stopping. My video is 2 mins long. I then press the preview button where it continues to slowly preview but only up to around 1.45 sec. At this point it jumps back to the beginning where the previously green footage of the first minute has returned to blue again.
I am running the latest version of After Effects (purchased last month).
I am using a MacBook Pro OS X 10.9.5
Processor: 2.9 GHz Intel Core i7
8GB 1600 MHZ DDR3
Am I doing something wrong? Could it be OS X not updated is a problem? I've scanned my computer for Malware - no probs there.
