missing audio after vob to mpeg renaming

Hi Everyone

I have a philips dvdr75 digital video disc recorder, where I burn my mini dv video to dvd (vob format) files.

I take the dvd, put in my dvd-rom, copy to my hard disk, and give the (video) vob file(s) an .mpg extension. I can play/watch them fine (audio and all) in Windows Media player 9.

I now try to take them into Vegas Video 4, where I can drag the video into the timeline, but no audio appears.

Does anyone know why? How can I get it to appear on the timeline -- obviously it's there somewhere, as I can hear it with Media player?

Thanks for anyone who can help!

That's because the audio is AC-3 in the .VOB. Vegas has an AC-3 encoder but not a decoder.

Thanks mjhig

Yeah, I figured it had something to do with the AC-3 encoding, but was hoping there was a way to still import it (any plugs for that?).

Geeze, as Vegas' creators initially developed and awesome sound software, I would think that their video editing program would be flexible enough to accept pretty much any type of embedded audio encoding (especially as you say Vegas wil encode to AC-3.

Thanks for your help, though.

Continuing to look for another solution ...

The best solution is to do your editing before you render to .VOB. VOB is comprised of compressed/lossy formats, Mpeg 2 = Video and AC-3 = Audio. Further editing on compressed/lossy formats will greatly degrade the file.

I'm assuming Sony decided that due to the above, AC-3 would be the final output and no further editing would be done.

I'm not familiar with your set top burner but if you can import or burn to CD/DVD-RW the raw files to Vegas you would be far better off. Or if you can capture directly from the cam to Vegas.

DVD2AVI is a free app. that will separate the audio from a .VOB but this is by far the least desirable method.
