Sony Vegas Pro 12 stops rendering

[Pyrexia93]

When I'm rendering my video with facecam it stops at %45-70 multiple times. I turned off gpu acc. and also encode mode: render using gpu only. Still coundn't finish rendering. Thanks for help ^^

What format are you trying to render the video as? Might be wrong but not sure rendering using only the GPU is the best way to go.
