Thanks for all your help guys. This is a new station for me, and it seems like maybe it isn’t just the settings after all. The videos glitch a lot, report dropped frames etc. even when I’m playing it at the lowest quality with safe RT. Granted I’m usually editing off a server, but this didn’t happen with the old computer. It also occasionally gives me an I/O error, or freezes in the middle of exporting.
This, plus the fact that compressor takes something like 15x real time to export HD makes me think something big is wrong. It’s a 2.3 GHz PPC tower with 5.5 GB of RAM, which I think should be able to handle this. Anyone have any suggestions?
EDIT: Just a thought: I read on another forum that power issues can cause rendering issues. I’m running a tower and a monitor as opposed to the iMac I used to have. This is in addition to a PC and monitor that have always been here. Could this be something?
