Missing audio stream?

DB73 wrote on 5/26/2010, 4:36 AM
When I import my MPEGII movies into DVD architect they play okay but the sounds drops out after about a second. The timeline shows the audio track but it does not show any waveform. The files play fine with sound through any media player I have tried. I also tried using the MPEGII files in a free DVD authoring package I downloaded (DVD flick) & in here the audio was fine. DVD Creator FREE handled the files just fine as well. Why does DVD architect have a problem? I'm using DVD architect 4.

Thanks.

..... actually I should have added that I had this the last time I tried to author a DVD using DVD architect. The only solution I could find at the time was to export the audio from Vegas as a seperate file & then use this in the audio track. I just could not get DVD architect to play the audio from the video. But there must be a better solution than having to export the audio as a seperate file from Vegas, where it plays perfectly fine?!

Where did the MPEG2 come from?

Was it exported as a DVD quality MPEG from a Sony Vegas project?

If it came directly from a camcorder, was it standard or hi-def? and which model of cam did it come from?

You should be doing them separately anyhow. If you're outputting as a single MPEG2, then you're 1) using one of the templates that are less optimal for video (the DVD Architect video stream templates contain the best DVD settings) and 2) you're giving DVD Architect MPEG audio, which it will have to re-encode as AC3 or PCM -- whichever your DVDA project is set for. That puts the audio through two encodes (one in Vegas, one in DVD Architect) for sure, and possibly the video as well.

Re-encoding wastes time and results in degraded media.

Use one of the DVD Architect video stream templates for the video and an AC3 or WAV / PCM one for the audio. Not only will it likely solve your issue, but it will result in a better quality DVD as well.

Cool. Makes sense. So this is what I should be doing when exporting from Vegas?

Any other thoughts on why the audio only plays for a second in DVDA but plays fine on everything else? I thought DVDA would have been able to handle this in the first place, even though, as you say, it's not hte best way to go about things.

Well, if it didn't play at all, then we'd know it was just incompatible audio.

But since it plays for a second or so, it could be that you need to update the audio drivers on your computer. RealTek regularly issues updates to their hi-def audio codecs, and that's always a good place to start.

If you're using a Windows computer, go to Windows Update and download the non-critical updates. There are frequently driver updates in there.
