Super long time rendering audio on DVD Architect Studio

lukeksk wrote on 12/1/2004, 10:53 PM
I have a finished 360MB avi file. I placed this onto a simple DVD Architect Studio 2.0 (DAS) canvas so I can make a movie to play on my DVD player. It took about 5 hours to render the video on my 1.5GHz 2GB RAM notebook but the audio rendering was super long. Just calculating from the time bar alone, I estimated that it might longer than 100 hours to render the audio (1% took slightly over 1 hour each) before DAS starts burning the DVD.

Is it normal to experience such a long time to get something out to DAS, esp the audio? Thanks for all input.

That's a long time!! Where did the avi come from? Is it DivX or XviD?

Something is definately wrong. On my 866MHz computer rendering the audio usually takes only about 1/8 the length of the project or so. If my project is 60 minutes long then it takes less than 8 minutes to render the audio.

I don't have Vegas Studio 4 so i don't know if this option is available, but ... can you render the AC3 audio in Vegas? This might go faster than having DAS render it.

Is that a DV-AVI?

360 MB is less than a minute's worth of DV-AVI video.

I'm currently having a similar issue with about 20 minutes of stills compiled in Movie Studio 4.0.

The "make movie" option to send it to DVDAS is showing over 5 hours, and I'm only using still with some light effects and about 5 mp3 tracks.

Any insight?

That is not unusual for a stills only timeline. However - be careful of the size (pixels) of the image files you are using. unless you are doing any deep zooming into an image you should pretty much keep them at no more than double the size of a standard NTSC/PAL DV frame. The bigger they are in pixels - the longer they will take to render out.

There is a recognized bug (at least in the community) around rendering to .ac3 format. Sometimes the render time increases dramatically (and just rendering to .ac3 should be far faster than rendering to MPEG). When this happens I simply stop the .ac3 render and try again. That usually does it. If that does not do it then I shut down Vegas - restart and try again. In the end... that has worked for me every time.

Bottom line is... don't let it continue "rendering" the audio if it says it will take longer than it did to render the video... as that will likely never be true.

I don't know. How to find out if it's DivX or XviD?

There's a handy utility called G-Spot which will tell you the codecs used to render an avi - if you can post that information it might be helpful.

I have to admit I was assuming that you used a file that wasn't produced in MS - as grisetti has pointed out, it's a very short avi if it's not something like DivX or XviD. If you did render it in MS which template or options did you use?
