5.1 or 2.0 Dolby possible on a media file ?

[plainman007]

Can i get dolby 2.0 or 5.1 onto a media file. Basically a WMV9 or MPEG2 with Dolby 2 or 5.1 channel audio. Or is it possible to get Dolby sound only when burning to a dvd via dvd arch ? I know that a wmv9 file can have 6 channels of sound but that isnt a Dolby soundtrack right ? Its just windows 5.1 audio and not dolby. Am i right or wrong here. Can someone clarify.
Thanks.

The 5.1 in WM9 isn't Dolby, as far as I know. But why do you want it to be specifically Dolby?

Hi David,

Basically marketing gambit. Dolby Stereo. Even though it probably wouldnt make a difference in the sound quality in comparision to a .wav. Im rendering a short film to be played on a hardware based cinema server. So i would like to render to dolby 2.0. I know this is possible when going out to dvd. But is it possible i can infuse dolby stereo in someway into the rendered file (which can be either wmv hd or mpeg2) ?

Thanks.

Why not render the 2.0 / 5.1 to ac3 and then your mpeg2/wmv seperately.
Most dvd authoring apps worth their salt accepts separate video and audio streams

Fst > The question here is to have either of them on a video file. I hope you understand the difference between a media file and a finished DVD. In fact DVD Architect itself can make dvds with dolby 2.0/5.1. But my output cant go to dvd. Its supposed to be a video file. Ive done this before thru another application that had the unique ability to make a video file with dolby stereo on it. Youll know because when you play that file on media player. The scrolling properties would show audio as dolby digital. Only thing i dont want to run my video thru 2 renders (= an extra render generation loss) just to get the audio into Dolby. I was wondering if it can be done within Vegas. And like David says. WMV can carry 5.1 or stereo. But it aint Dolby.

Yes it does. I already answered the same question to David asked me. It matters in terms of marketability. Dolby 2 also compresses the audio file size and makes it smaller while maintaining all frequency in the human audible range or at least the range that would matter to the movie experience. But mainly wanted to have it as 'Dolby'.
