Hey Dave
I don’t imagine processing or memory is the issue. It’s such a small task that the computer handles seamlessly until the end of the render. Seems like a glitch.
Here are my specs though:
Macbook Pro 10.6.8
8GB Ram
AE CS5.5 (just says 10.5)
Stock card for the computer
I do not have Render Multiple frames enabled
2GB available for other apps. 6GB for AE.
Footage is in Pro Res 422 and I’m exporting the same. Also tried exporting Lossless and same thing
