I just tried to render it in V13. Crashed again at 53%. THen monior went all crazy and flickered for about 5 seconds...got a message that Nvida driver had stopped responding but was responding again. It may be the video card..although it's been working fine so far. I have noticed the last few days some vudoes are starting to randomly stutter slightly.

This is a dance peice so I can't cut it up and render in sections, I've rendered it before with no problem as an MP4 for Youtube. This time I'm rendering for DVD Architect.

OK so deleted V13. Still freezes at 53%. Obviously there is something there causing this..but since I don't know where exactly in the video it is I can't play with it. This is a pivitol peice in this concert. My next step is to try another render format and hope it will work in DVD A.

Next step. I'm going to save it as an ,avi file and hope it will work in DVD Arch. The other files are rendered as mp4. Will there be an issue with mixing formats ?

why can't you render in sections?

once you stitch them together it should be seamless - use a lossless codec if need be...

well at first I was thinking I don't know where the hang up is..but I guess it doesn't matter. I could just cut it into 5 easy peices. But I was thinking it would not be tight.. and since it's a dance peice it needs to be rock tight. I will try it.

The render in .avi did work however.

Fosko -
First, have you tried turning off GPU support in the "Render As" template?
Second, are you making a DVD of Blu-Ray disc?

Away from system at moment but will check GPU when I return. It is DVD..not Blu-ray.

OK I didn't see it in the Render Custom...but I found it in the settings prefereneces. IT was checked. I unchecked it and am running a new render now under DVD Arch Wide Screen, Will post results.

I don't even know what GPU acceleration is for.

WORKED~~~~~
Thanks.
Wish I'd thought of that. Now I need to go find out what is GPU and when should I use it.

First, if it's for a DVD then you should be using a DVDA template in the Main Concept MPEG2 list. This is how you make a DVDA compliant video file. Anything else will force DVDA to re-render the video with a hit on the quality. You also need a separate AC3 audio file.

If DVDA wants to re-render your video than you did something wrong in Vegas.

A GPU with CUDA cores will help with some CODECS, notably AVCHD.
There is NO GPU acceleration for MPEG or AVI.
There are three locations to control GPU acceleration inside Vegas:

There is the overall GPU acceleration setting that is found under the Preferences which accelerates preview, fx and even renders of certain CODECS.

There is also additional CUDA acceleration settings at the CODEC options in some "Render As" menus.

Last, in Preferences, Preview Device, there is an option to "Optimize GPU Display Performance".

I've contended all along that GPU support is just a band-aid for slower processors. I believe it is a direct response to all the users who were demanding GPU support "because Premiere has it". It was a marketing decision - and like many marketing decisions probably not fully supported by the development team (my speculation) - it's been a disaster for Sony. Be careful what you wish for - you might get it. Sony has no control of the GPU after it passes the data to the graphics driver, but if the driver crashes, users tend to blame Sony.

This is why I recommend that all new users turn GPU support off in their preferences to start. This really should be the default out-of-the-box setting. Get Vegas running, test everything you expect to use, and *then* enable GPU support.

Thanks for that explanation. It helped.
I was running a DVDA template.. that's where it was crashinng. When I ran the .avi it didn't crash, But now that I removed the GPU I can go back to using the DVDA templates

UGHH
I just downloaded Vegas 13. I rendered another video and it happened again at 80%. Thanks to you good people I knew just what to do (after48 minutes of rendering) to fix it. But WHY does Vegas ship with the GPU ON ???

"But WHY does Vegas ship with the GPU ON ???"

I ask the same thing often. Turning off GPU support has fixed so many people's problems it doesn't make sense to force new installations to be test subjects.

I've made the suggestion on the "Product Suggestion" page, maybe if others do as well?
