Hi all. I'm trying to render some video in preparation for burning to DVD, and I'm getting some strange problems at certain bitrates. It has me totally stumped, I'm hoping someone here has some ideas.
I'm rendering the video with the included MainConcept MPEG-2 codec, so that I can burn it later using DVDA. I have all of the quality settings as high as they go, and I initially rendered it at CBR 9.8 (this is an instructional video, little motion, so sharpness is a big issue). The video rendered perfectly in this case, and I was able to burn it. However, due to the bitrate, some bits of my DVD turned up missing, and I'm now trying to re-render at a lower bitrate.
Thats where the problem starts. I go to render the video again, changing no setting other than the bitrate, which I change to CBR 8.0, not a big difference. I start it rendering... and it quits about 15% into the render, with an "unknown error has occured" message. I have tried rendering it many times now, hoping it was just the computer acting up that once, but its doing the exact same thing every time. I tried CBR 9.8 again for the hell of it, it rendered fine. I then tried CBR 7.5, it ran a bit longer than the last one but again ends with that error.
Why would one bitrate succeed while others fail? What really is the difference? I have it currently attempting another render at VBR 7.5-8.5, so we'll see if that works, but I really wanted CBR. And the fact that the error message is totally unknown is what buggs me, like its an issue with my computer and not Vegas, but I haven't found any proof of this. Anyone have any ideas at all?
