I have a Powermac G5. OS 10.4.11 2.5 GB DDR2 SDRAM This is regarding to FCP 5.0 & iMovies 6.0.3 exporting for internet streaming. I want to export a MPEG4. Tell me if you need to know what setting i'm exporting on. The projects that I'm having trouble with are around 3 or 4 minutes long. It unexpectedly quits when exporting is half way done. If I export only video, it allows. If I export only audio, it works. (exporting as quicktime files and MPEG4) Exporting on the same MPEG4 settings sometimes work on 1 minute projects, and 6-7 minute projects. What I've tried before trying again: Restarting the computer, bringing all files that are involved with the project off of the external drive onto the desktop, disconnecting all external drives, and attempting to reinstall FCP. But I dont' know how to do that. Deleting the FCP and reinstalling didn't do anything. Please Help.
