Sony Vegas 0% CPU usage when rendering

[BELZI]

Hi, I'm trying to render video, but every time CPU usage for Vegas drop down to 0%... I rendered one video today, so I really don't know, where is the problem.

Please give more info.

So it stops encoding when the CPU drops down?

What is your source video? Try different video sources too see if it makes any difference.

What is your output settings? Try different output settings.

If the video is able to render fine, maybe your GPU is taking up the load.
