Help with sound on AVI to SVCD conversion

[Stoddo2k]

Sorry if this has been asked before but I couldn't find the answer.

I have an AVI file that upon Tmpgenc conversion to SVCD has no sound. I have tried to process the audio out with VirtualDub first but it gives an error:

"The requested audio conpression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested format."

This is of course an attempt to change the sampling rate to 44.1 khz. I next tried a direct stream copy of the sound out of Virtual Dub (1.4.10) and created what appeared to be 48 khz wav files. But upon trying a couple of programs to changed to 44.1 khz wav files it fails. I tried dBPowerAmp music converted but it complains about the ACM codec not being installed (I do have the Nimo codec installed).

So, can anyone recommend a better utility for converting 48 khz wav to 44.1 khz wav (or mp3)??? Or tell me what I am doing wrong here??

Thanks for the help.

Unless you absolutely have to make a 'std' SVCD don't downsample. All DVD players have to support 48hz for DVD and most will accept a 'non-std' 48hz audio SVCD. See http://www.doom9.org/mpg/dvd2svcd.htm

As you did, save the audio out using vdub->direct stream copy. This is probably a VBR encoded mp3 or ogg-vorbis file. No matter, if you can play it you have a suitable codec. Once saved, use Besweet (with GUI) or HeadAch3e to convert to wav. Downasample at this time also if you wish.

Hope this helps

Hmmmmm. Well the 48.1 khz wav file from Virtual dubs direct stream doesn't play properly. The sound comes out distorted. Also, when trying to use BeSweet to downsample the wav from 48 khz to 44.1 khz it gives an unknown input type file error. I know that the original audio is 448 bit/s and 5 channel. So does this mean I am missing a codec??? Like the Ogg Vogis?

If its 5 channel its probaby AC3, use Headach3e to convert to wav. You will also need an AC3 codec, you can find one in the nimo codec pack. Find it via the tools section on the left of the page.

actually, headach3e will convert to .mp2
use VDub, set to full processing mode, save wav, change the extension of the file to .ac3, and then load that into headach3e, and converto to .mp2 and mux that with your video later

Actually I think in this case its set to direct stream copy.

Not at home at the mo so can't check but I thought Headach3e could convert to wav too?? Anyhow, doesn't really matter as your right in that .mp2 is the format he needs

[Stoddo2k]

All I can do is set Virtual Dub to direct stream copy and save wav as it errors for full processing mode. I tried to rename the wave to ac3 and use BeSweet to change to mp3 but again unknown input file type error.

Also, when I try to d/l HeadAc3he from doom9.org it is a corrupt rar. So, is there a different place to d/l HeadAc3he from???

Is there a sure way to tell what the sound encoding is in the AVI? Windows Media Player gives little information.

[bugster]

you can check the encoder use by going to file->file properties in vdub. That might give some hints as to where the problem lies.

Try using Google to find HeadAch3e if the doom9 archive is corrupt. Have you got the latest winrar? I think there could be a compatiblity issue if it was rar'ed with the latest version that would stop it being unrar'ed with an older version.
