Hi guys... I am currently working on a Quad-Core Mac Pro, 2Gb Ram and I do a lot of work with After Effects 7. The machine has been working fine till yesterday, when I went to render out a 2min video from after effects, it would get about a third of the way in the render queue and then crash. I've been thinking it may be due to installing the update Quicktime 7.1.5 earlier that day... It was working fine with Quicktime 7.1.3. Has anyone else experienced this? Is there a way to convert back to an older version of Quicktime on a Mac? Any help would be fantastic... I've tried reducing Cache Size, Max Ram usage and purging every 5 frames in the secret menu, but sill not working well. Cheers.
