Missing Audio

[PaulStat]

Hi I recently tried for the first time to burn a xdiv file to a dvd using TMPGEnc Plus to encode it and TMPGEnc Author to burn it to DVD-R. When it completed however the dvd was missing the audio completly, the audio_ts folder did exist but there were no files in it. Can anyone explain why????

A wild guess but I bet your xvid has ac3 audio. Open it with Gspot to confirm that.

If so TpmgEnc cannot encode ac3 directly - you have to either convert the ac3 to wav and open that as a seperate audio input or (if you want to keep ac3) extract the ac3 with virtualdubmod and open it as the audio source during the tmpgenc author process

Thats what it tells me the audio codec is

0x0055(MP3) ID'd as MPEG-1 Layer 3

I'm guessing thats MP3, so should that work or what?

Thats normal. The AUDIO_TS folder is for DVD_Audio, not for the audio that goes with a Video.

What happens wehn you actually play it?

Well when i play it I can see the video clearly but the sound just isn't there. I know there is sound with the avi file cos i've watched it several times.

It doesn't necessarily have to have AC3 audio for it not to work. I've actually had some DivX files that I created myself that I wanted to slap onto a VCD, and a few of them just wouldn't encode the audio in TMPGEnc (all the files were created with the same codecs, etc). The audio was MP3.

I exported the audio as a wav file through VirtualDub, then using that audio source in TMPGEnc and that solved the problem.

And what about the mpeg file output by TmpGenc, before you put it into TmpGenc DVD Author, does that have sound.

Do you get sound when the DVD is played on the PC but not on the standalone player?

I am thinking three possibilities here.

1)You configured TmpGenc incorrectly and it generated a video with no audio.

2) The avi audio is bad so TmpGenc generated a video with no audio

3) You created a DVD with mp2 audio but your standalone does not support this format (some U.S. players don't)

yep...it seems like you're putting an incompatible audio steam into TDA. If you've got mp3 audio it's not gonna know what to do with it. You need to decompress to pcm or mp2

Ok folks I seem to have solved the issue of no audio. What I did was to go into VirtualDub and extract the audio. Only problem is I tried to select full processing mode instead of direct stream copy so I could select the audio compression, now when I try to save it as a WAV it says no audio decompressor found.

So i reselected direct stream copy and then save as a WAV, which it seemed to do, and it created a 100MB file (does that sound about right for a vid thats about 1hr 30mins?)

Anyway I managed to re-make the MPG file with TMPGEnc, only problem now is when its finished and I have a look at the file the video seems lag by about 5 seconds to the audio??

In order to decompress you need to select full processing mode, if you don't then you're just saving the audio as-is, in this case MP3 (even if the extension is .wav). A 90 min wav file should be about 1 GB or so.

Did Gspot report the MP3 codec as being installed?

Try Goldwave for your wav extraction, just load the avi then save.
