Audio formats

Hostie wrote on 3/17/2006, 5:35 PM

I've edited a video using Vegas. The only option for saving the MPEG-2 file is to use the MAINconcept encoder, and there is no way to change the settings. It defaults to saving the audio in MPEG layer 2.

But my copy of DVD Architect supports only uncompressed WAV audio. Is there a plug-in somewhere that will allow me to use the MPEG layer 2 audio in DVD Architect?

Or is there a way in Vegas to save an MPEG-2 file with uncompressed WAV audio?

If you're using the full version of Vegas (as oppossed to Vegas Movie Studio), you should be outputting your audio in AC3 format. It is about as compressed as MP3, but is actually a standard format used for DVDs, whereas MPEG audio is not. (At least, into in North America it isn't. It's more accepted in Europe.)

After you've rendered your video to MPEG2 (use one of the DVD Architect video stream templates), go to Find -> Render As again and change the Filetype to Dolby Digital and render that out to an AC3 file with the same name (other than the extension) as your video file. DVDA will pick up the audio file when you bring the video into a project.

If you choose use WAV audio (possibly clearer, but less supported and much larger file size), then choose Wave as the filetype. Either way, DVD Architect prefers that your video and audio file be separate. Although you can give it a video file with the audio embedded in it if you want -- DVDA will simply demultiplex them and encode the audio into a proper format (AC3 or WAV/PCM).

If you're using Vegas Movie Studio, to the best of my knowledge, it outputs a separate WAV file by default. Last I heard, VMS doesn't do AC3.
