Help: No audio track when demuxing VOB

[thai_tx]

Hi,
I tried to demux VOB file using TmpgEnc Mpeg Editor. The 1st 10 seconds of the VOB file has no audio, since this is only the intro, I want to cut that part. But after cutting that part, the output mpeg does not have audio at all. I tried demuxing the VOB file, but TmpgEnc does not see the audio stream. Is there a way to fix this audio problem?

What format do you want to create in the end for your file? MPEG2?

If I had to cut a part of the video out, I would do it in different ways depending of what final product I want.

If I want to put that video on a DVD, I will cut it in TMPGEnc DVD Author directly.

If I want to create a single MPEG2 file (or MPEG), I will extract the audio part of the original VOB file with VirtualDub-MPEG2 and have a WAV file of it. Then I can edit the WAV file to increase the volume or fade some parts or whatever. I will then import the VOB file in TMPGEnc as the video part and the WAV file as the audio part. I'm pretty sure it will work that way.

Hi Gildas,
I want the output format to be VOB. I already tried TMPGEnc DVD Author, it does not see the audio track. I will try VirtualDub-MPEG2 to see if it can extract the audio part.

If your original VOB commes from a ripped commercial DVD, the audio is probably encoded in AC-3. Unless you buy the AC-3 codec, TDA can't handle AC-3 by itself.

You will need the AC-3 ACM Decompressor to be able to extract the audio from the VOB in VirtualDub-MPEG2.
