poor audio quality after having burnt a dvd cd

[nille]

Hi!

This is the procedure i've followed:
I've got a divx file, from which I extracted the audio using virtual dub. After that I used DVD2AVI to convert the audio to 44, 1, which I have done many times before (when making svcds) with very good results.

I then followed the guide( https://www.videohelp.com/tmpgencdvd.htm)on this site on how to make a dvd mpeg file using Tmpgenc and loaded the video and audio separately into TMpgenc as usual.

After that I used this guide(Ulead dvd factory)
(https://www.videohelp.com/forum/userguides/139093.php) to author the dvd before I finally burnt it using Ulead dvd factory as well.

The resulting video is very good quality wise, but the audio is terrible. It's usually very good when I make svcds, but now it's really poor. I must have done something wrong somewhere. Can anyone help me?

I'd be grateful for an answer.

If you're making a DVD you need to convert the sound to 48000hz, not 41100hz.

Sorry I was wrong before, I've been converting the audio to 44.1not 44.1.
Do you still think this could explain the poor sound quality?
One more question: When I've extracted the audio using Virtual dub(keeping 48,000), do i need to make any other audio settings somewhere in the process?

Are you using MPEG audio, or having it converted to LPCM when you burn? If you're using MPEG audio, what bit rate are you using?

[nille]

I've described the process above. I extract the audio using virtual dub. I changed the audio to 44,1instead of keeping 48,00, which is apparently wrong, someone told me here earlier.

Then I load the video file and and audio file into TMPGenc and start encoding. I didn't change the audio bitrate anywhere. This is how I'm used to doing it when I make svcds with excellent sound.
Is it different when making dvds? Should I have changed any setting at this stage?

Then I authored the file in Ulead dvd movie and burnt it in the same software. Like I mentioned before the audio was really crappy but the video was excellent. So I'm afraid I don't know whether I've changed the audio to LPCM or not. I don't know where to do that or if it is necessary.

Could anyone please tell me what i'm doing wrong since the audio is so poor?

This is what it says at the bottom of TMPGenc while I'm encoding: Layer-2 48000Hz 384kbps)

What am I doing wrong to get such lousy audio(it sounds very metallic and generally poor)

Please help me solve this very frustrating problem.

I changed the audio to 44,1instead of keeping 48,00,... I didn't change the audio bitrate anywhere.

Huh? Did you or DIDN'T you change it? And if so, using what? If in VDUB, is it using a plugin like BESWEET or something? (Sorry, but I no longer use VDUB, so not sure what it does to audio.) I find BESWEET to have a horrid metallic conversion sound. Several other freebies do the same. This may be the problem. Some cheap program, whether at capture or at a conversion, is hurting the audio. We'd need you to go step-by-step from source to final in order to find the cuplrit.

Thanks for your advice, but i'm afraid this was a bit too complicated for a newbie like myself.

What I meant earlier was that I did change the audio from 48 to 44,1 in virtual dub, but other than that I didn't change any audio setting anywhere.

I'm really looking for an easier-if possible- way to improve my audio quality when making a dvd. I can't see why the audio is so much better when I make svcds(extracting the audio with virtual dub, and then changing it to 44,1 with dvd2avi) than it is now.

Has anyone got an easy solution to what could be done to improve the audio quality?
