Can I convert vobs to mpeg2

[c.pugwash]

Can anybody tell me which is the best program to convert vobs from a dvd, to one big mpeg2 format. When I get the vobs back tp mpeg2 I will then be able to edit it with video studio.
Thanks for any help.

ReJig. Takes any # of VOBs and extract the video as m2v and the audio track(s) in whatever format they're in.

Thanks for quick reply, I will give it a try now.

can you help, when I demux the vobs it either gives me 1 m2v file or a m2v file and an ac3 file, what I need is a combined sound and video file. Where am I going wrong.

Join / Multiplex the m2v and ac3 with for example tmpgenc, under file->mpeg tools simple multiplex. But some editing and authoring tools can import m2v and ac3 separate.

Like Baldrick says, you can multiplex them if you want it as a system stream. The reason for separate audio and video files is that that's the way it is in a VOB. Beware tho, that (judging from a similar thread last week) some/many editing tools have a hard time with ac3 audio.

I now have managed to multiplex the audio and video, this now plays fine with windows media player. But when I import the mpeg into visual studio, there is no audio.If I import into windows movie maker it comes up with following message:
E:\stream test\office\demuxed\MPEG1_Video_0xE0.mpg could not be imported. An interface has too many methods to fire events from

I was solving the same problem last week:

1) Demux DVD (VOB) using ReJig to video stream (m2v) and audio stream (ac3)

2) convert ac3 to wav (you can use Goldwave for free), because most programs have problems with AC3 import

3) than it is possible to import video and audio to TMPGenc or to some editing applications

Thanks I will give it a try

Yeah:

many editing tools have a hard time with ac3 audio.

Womble MPEG Video Wizard and MPEG-VCR are frame accurate MPG editors that handle AC3 no problem. You can load the original VOB's directly without converting to MPG first, too. There is no re-encoding of either the video or audio if simple cutting and joining is all that is done.

If you don't need frame accurate editing (like just to remove commercials, for example) you can load your demuxed files into MPEG2Schnitt to trim and select chapter points. AC3 is no problem for MPEG2Schnitt either, and it is free.

If your source VOB's are not complex (one video and one audio file, no subtitles, etc. - like what you would get from a DVD recorder) you can also use Simple File Joiner to join the VOB's and save them as a single large MPG in one step. I use this method frequently. Freeware at :

Just rename the VOB to MPG and Video Studio (as well as many other programs) will open it fine. If the input VOB contains LPCM audio, which some do, there is no problem. However, in your example, the VOB obviously contains AC3 audio, which the "basic" VS software does not support. However, if you are running VS 8 (or upgrade to it from an earlier version), there is a new plugin that provides support for AC3 audio (they call it the Dolby Audio Plugin on their website). The other option is to convert to WAV, as has been previously suggested. The problem with that is you loose the audio compression of AC3 and you have yet an additional conversion step in your process.

For me, the $29 price tag on the VS 8 plugin is well worth the expense, since it saves time in audio conversions and also gives you AC3 capabilities ... a feature that will save huge amounts of space on all of your output DVDs, compared to the horrendously large audio that you get by default in VS with the LPCM output that it provides.

Another solution that I often use, if I am doing simple cutting/merging of VOB files is to again rename them to MPG and use TMPGEnc MPEG Tools for the editing. It's not nearly as clean (with cutting) or flexible (filters, sound volume, effects, etc.) as VS, but works great for simple projects.
