does vcd support multiple audio tracks

[Ulver]

Does the VCD or SVCD format support multiple audio tracks. Suppose I want to make a (S)VCD with both normal audio and a commantary track?

VCD does, SVCD doesn't.

SVCD supports multiple audiotracks.
try dvd2svcd works perfect, also with 2 or 3 subtitles

I'm sorry, I'm not quite awake yet. I got it backwards. VCD doesn't. SVCD does.

Thanks a lot. Nice to know it's possible. The problem remains, however, that I can't find a clue anywhere as to how one goes about doing it. Can anyone give me some pointers. I do use dvd2avi and have no problem extraction the varoius audio tracks to *.wav files. It just dosen't seem possible to encode a mpeg streem with more than audio track. And even if I did figure that out I'd still need a menu that somehow alloews the user to chose audio track for the movie.

Both VCD and SVCD support two audio feeds, but they're applied differently. In VCD, you encode half of the stereo channel with one language (or commentary), and the other half with the other language (or commentary). To hear only one audio program at a time, you must switch your player to MONO mode and tell it which channel to play, left or right. In SVCD you can have two stereo/surround tracks that are fully multiplexed with the video track. To hear one audio program or the other, you just press the AUDIO button on your player. If you have somehow managed to create and properly multiplex an mpeg5.1 audio program in your SVCD, you cannot have other audio tracks. My Apex player, before it died, also played non-standard SVCDs with 4 separate audio tracks.

So I suppose I should go with SVCD if I want to keep the "normal" stereo sound track. I still can't figure out how to encode the mpeg-2 stream with multiple audio tracks. Or are you sopposed to adde the second audio track to the svcd seperatly somehow?

[AntnyMD]

If you're using TMPGEnc, encode the video and the first audio stream .. then when thats done, encode the second audio stream WITHOUT the video, Then go into TMPGEnc Tools, open the first encode with the video and audio, and multiplex the second audio stream onto it.

[Ulver]

Thanks a lot. That really helped.

[Ulver]

Should I encode the second audio stream using the SVCD templet as well?

[AntnyMD]

It doesnt matter. You're only focusing on the audio settings for the second audio track. Make them the same as the audio settings for the previous encode.

If you want to use regular VCD, everything you need to know is here: http://forum.vcdhelp.com/viewtopic.php?t=77485.

bbmpeg will also mux in multiple audio tracks into a mpeg ... but keep in mind they have to all be synced up before ... that or you need to fiddle with the delay for each track when muxing
