Premiere Pro constantly crashes during rendering & exporting
I am editing on an iMac: (27-inch, Late 2013)
Processor: 3.5 GHz Quad-Core Intel Core i7
Memory: 8 GB 1600 MHz DDR3
Graphics: NVIDIA GeForce GTX 780M 4 GB
I am trying to export ~2 hour long 1080p videos (they're 2 hour long lectures with very minimal edits, just the video in between an intro and outro). Every time I try to export, it exports about 75% of the video fine and then crashes my whole computer. I thought maybe something in the project got corrupted, so I created a new project from scratch and then exported. This solves the issue about 50% of the time. But the computer still crashes 50% of the time even with a new project. I can't imagine that the odds of multiple projects becoming corrupted in succession are so high.
I've also tried to first render the video separately before exporting, and for one of my videos, that solved the issue. It rendered through just fine, and then allowed me to export properly without crashing. But for my other video, the computer still crashes about 75% of the way into the render.
In Premiere's Memory settings, I've assigned 7GB of RAM out of 8GB to premiere. When I am rendering or exporting, the computer is not running any other applications except for maybe 1 or 2 web browser tabs in Google Chrome.
When I export shorter videos, ~5 minutes in length, this issue does not seem to happen.
Is this a RAM issue? I'm not sure why this continues to happen or what to do. Please let me know if any additional settings are needed to look into this issue, and thank you in advanced for any help you can provide.
