Does it crash at the same time every time? Does rendering to a different format solve the problem? Many times there is a bad piece of media and that causes a crash.

Hey Sorry for not replying sooner. I got cought up with some work.

I've tried everything in the FAQ 16 about crashing during rendering.
It always seems to crash after rendering about 3-5 seconds of video.

I've tried different formats and that didn't help either.

One thing that did work is splitting my project into small 3 second sections and rendering each section individually with Vegasaur Transcoder. However it is then almost impossible to join the clips back together after due to the slight empty space at the beginning and end of the rendered clips which, for a music based project like this, is not really an option.

One interresting thing that happened however is that sometimes instead of crashing it would say the program had run out of memory. Maybe that can give someone a clue as to what is wrong here.

If anyone is interested below is the mediainfo for one of the clips used. All the clips are in exactly the same format so I don't know if that's the problem.

Hope someone can find me a solution because this is really frustrating at this point. I don't even care if it takes 3 weeks to render I just want it to actually finish.

The input file is x265 codec. I'm not sure Vegas handles that.

178 Kb/s is an extremely low bitrate. It looks like the input file came out of Handbrake. If you are the one who ran the file through Handbrake, try using the original file as input.

Also, what output template are you rendering to, and what is the target bitrate?

You might want to review this thread, too.

The source files appear to be HEVC from Handbrake. Is it possible that you have (or could acquire) the video in some other form? Prior to Handbrake encode?
