Rip DVD track – increase volume on audio – and put back
Rip DVD track – increase volume on audio – and put back
by Lynn Hyland on Dec 6, 2008 at 1:14:28 am

I have a DVD on which one track has very low audio. The files associated with this track are:
VTS_02_0.BUP
VTS_02_0.IFO
VTS_02_0.VOB
VTS_02_1.VOB (This VOB file is MPEG and opens and plays in the video viewer software.)

Is it possible to rip this track, increase the volume, put it back and burn a new DVD with equal decibel levels?

Thanks so much for your suggestions.

How? Let's be clear on the problem. One chapter has a short segment in the middle of it with low audio. The audio needs to be raised in that segment only and than the DVD remade without redoing all the chapter markers and everything else. Exactly what needs to be done? Thank you.

Sorry...You already listed all the steps so I didn't add anymore info. Rip the audio to aif with a tool like MPEG Stream Clip, bring it into your NLE and raise the audio levels. You'll need to re-author the disc from scratch with the new audio. Do you have the original authoring project?

There are other tools which will replace the audio at the VOB and IFO levels but you really need a good grasp of the DVD spec to do something like this. Here's one particular guide:

Duh! Of course you don't have the original project or you wouldn't be asking the question :)

The easiest way is to extract ALL assets from the disc you have and re-author from scratch in whatever authoring tool you have. Other than that you'll be facing a steep learning curve.
