Premiere Pro v6.0.0 is the CS6 version. The first thing I'd recommend is installing updates, bringing you to v6.0.2. Get em here.
Are you exporting directly from Premiere or sending it to the Adobe Media Encoder?
Hey Josh. Thanks for the reply
I just updated premiere, gave it another shot...and it still had an erorr about 25 minutes into the rendering!
I am trying to render right out of Premiere itself.
Trying queing up the render and export from AME. Does that help?
Unfortunately not I appreciate all of the help so far though. I have still tried a few more times and it is still stopping at the most random of times.
How about rendering to another format, preferably a lossless format. Then bring that render into AME to convert to MXF?
If you have GPU accelertation enabled in Premiere Pro, try switching to Software Only.
Are you queuing the job to AME or clicking "Export" in the Export Settings dialog (which encodes directly through Premiere)? Whichever path you're going down, try the other one.
I'd also keep an eye on your resource usage, especially RAM, while encoding in progress. With 8GB of RAM, I'd be surprised if that were the problem.
Lastly, if you're encoding through AME, then you might want to post on that product's forum: http://forums.adobe.com/community/ame
