DivX -> SVCD audio problem

[ulf_and]

I have a DivX file with a 48000 Hz sound track. I want to convert it to SVCD with TMPGEnc, but first i need to convert the audio to 44100 Hz.

I tried to do this by ripping the audio track with virtual dub and converting it to 44100 Hz with WinAmp (also tried other converters), but when i convert it the audio is not in sync.

Also noticed that the 44,1 kHz audio file was 3 sec shorter than the 48kHz. Tried to add 3 seconds silence in the beginning, but with no luck. Still out of sync.

Anyone know how to do this?

Dont know if this will help or not but..i used "vdub-mp3-freeze" program..it seems to lock the video and sound together when splitting a file...and to change the audio freq...load into program the avi using the full processing mode instead of direct streaming ....you will be recompressing the avi....then choose the compression choice under video and choose your choice for video....say divx codec 4 low video...you can also set the bitrate parameters in the config tab there also...then for the audio choose the audio tab and choose compression....choose mpeg layer 3.......then over to the other side is the freq choices...then go back to save file as avi...it will recompress the avi using these choices...you can go to tools section and find a good template that somebody has already setup these parameters to work as such...but personally if lower audio freq it will sound like a tin can... )

USE TMPGEnc and go to audio. Adjust it to 44.1kHz, 224kbs, stereo and mpeg1 audio layer 2.

i prefer to use vdub to convert the files. just turn on audio- full processing mode, then compression - none pcm, then conversion 48000-44100. then file save wav. it should only take 2-3 min (it'll create a huge wav, 1gb+). then in tmpgenc choose that as your audio source. i ususally do this to all my converts, just to be safe and make sure there's nothing hosed in the file, i haven't had any problems since i started using this method.

Hmm - I just started to play with SVCD and the first thing I wanted to do was to convert a DivX file to SVCD. I had not known about the 48 to 44.1 problem till I tried tmpgenc and it barfed on the sound. So I ran the Divx file through Virtualdub and set the sound to MP3. I am now in the process of running Tmptenc now and while it's working (slow) I have no idea if I will get any sound out of it

Better way is to get scmpx ( http://www.sonicspot.com/scmpx/scmpx.html winamp ripoff that does a good sample rate conversion), or ssrc ( http://www.milky.ne.jp/%7Egalaxy/ ). Both can be setup as exteral tools in TMPGEnc, ssrc is also usable form AZID/LAME GUI by Danni Din and SCMPX can be used on its own.
