VS8 with AC3 Plugin - creating a true 5.1 DVD

[sgronow]

Hi Guys,

I have a .avi file (2 channel audio) is it possbile to resample the audio into 5.1. Ie. 6 channel instead of 2 ?

I have used the AC3 plugin and have sucessfully created a 2/0 Ac3 File


Thanks

You can't do it with UVS. There is actually a way to expose normally hidden settings in the output options dialogs where 5.1 is an option, but when I tried it, it still created 2-channel audio.

DVD Workshop 2.0 will create 5.1 audio.

I believe DVD WS 2.x will decode Dolby 5.1, but it will still only encode 2-channel Dolby Digital.

While I have DVD Workshop 2, I have never used it to produce anything but dual channel Dolby stereo. It has the same AC-3 power pack 1.0 which is the one sold as an add-on to VS 8, I believe. The only reference to surround sound, multi-channel audio that I could find in Workshop's help is the following:

"Surround Sound Emulation Select if the original audio track of your title used more than two channels (e.g. Dolby® Digital AC-3) but was converted to a 2-channel audio track (e.g. Dolby® Digital 2-channel) before importing to DVD Workshop. Selecting this option will simulate the audio track's original audio format when playing back your video on a DVD player."

Ken is correct! I want to take a 2 Channel video file and resample is a 6 multi-channel output.

There are ways of doing it. There are lots of freeware utilities around there on the web that can be used to produce 5.1 AC3 from stereo DV capture. Lookup the following: (www.vcdhelp.com)

BeSweet : for converting multiple mono wav files to 5.1 AC3
ifoedit : to create DVD folders (no menu support)
Audacity : to edit and produce 6 mono wave channels from a stereo wav file.

VS can be used to produce Video only MPG file and wav file of the footage and use above tools to produce the desired AC3 file and the DVD folders. The folders can then be burned to produce a DVD.

It is feared that BeSweet does not produce fully compliant AC3 but it works on my standalone DVD player and I get all surround channels.

However, one must remember that simulating surround channels from a stereo stream is not going to produce any real sound effects. All you get is pseudo-surround. If you want to add extra special effects, such as completely different sound tracks for surround channels, it makes more sense.

TMPGEnc DVD Author is a shareware utility (not very expensive) to produce a DVD Video disk with full menu and chapter support.
