VOB to MPEG2 - How?

[dh]

Any programs or ways to convert the vob in the DVD to mpeg2 preserving the original bitrate?
I want to edit the resulting mpeg2 and burn it back to DVDR.

TMPEG will convert vob files to mpg2 and preserve video and audio bitrate.

read one of the many guides on this site (guides link on the left) and it will tell you how to do it. Based on your question, I am guessing that you are brand new to this and have not read anything about how to do dvd creation before posting. Based on that, I would recommend that you download DVD2SVCD and a guide that shows you exactly how to accomplish what you want to do.

I have run over the guide before posting. Could you please tell me where in the guide has such information? I am not going to change them to SVCD format.

As far as I know, the .vob files in the DVD are merely mpeg2 files but cut up to pieces, each of them not more than 1 GB. The only difference might be the headers or something like that. What I need is a way to join them up together to form a single DVD compliant mpeg2 file.

Easiest way to extract perfectly without an encode it to use VOBedit and it'll pull the AC3/PCM and MPEG2 files right out for you to use.

in that case use DVD Deccrypter to rip the movie to your hard drive.....make sure you go into Tools>Settings>File Mode and check the box "Merge VOB Files"

You'll then have a big VOB file.

Next, simply change the DOS file extension from .vob to .mpg and you'll be able to edit with TMPGEnc.....but you'll almost assuredly have an MPG with AC3 audio. If that doesn't work for you, then demultiplex and either use BeSweet to convert the audio or use VDub to make a Wav file from the original MPG, then convert to mp2 audio. The Mux the two back together.

This method leaves the video as is....no quality loss

[txpharoah]

Actually, you can almost never just change the extension from VOB to MPG and have it open. Not that simple. Must extract files somehow.

But yes, in all cases, rip DVD to HD first if it has CSS.

Thank you very much, txpharoah!
VOBEdit works.

My story is that I created a mpeg2 file and burnt it to DVD+R after authoring with DVD Workshop. Afterwards, I deleted the mpeg2 file from my hard disk. Later, I wished to modify some aspect of the video content but there was no way to recover my mpeg2 file from the DVD+R.

Where is this box to tick "Merge Vob Files" ????

ZenZen:

My options>file mode screen looks different then yours....I have version 3.1.4.0

but I suspect your "File Splitting" box has a pulldown screen where you may find that option

Txpharoah:

you said "Actually, you can almost never just change the extension from VOB to MPG and have it open. Not that simple. Must extract files somehow."

that comes as quite a surprise to me since I've used this method half a dozen times to put a couple of dvd's onto a dvd-r.

It's true that WMP won't open the file....I suspect because of the AC3 audio.
However, TMPGEnc will open it, as will VDubMod and MainConcept.

In other words.....you're wrong....it is that simple

[dcsos]

you're wrong....it is that simple
said mmasw....CAREFUL DUDE!!!!!!

Its simple to change the file extension and in TMPG's case it works no problem

but when you do this you are not fixing the HEADER or TEXT part of the file that either describes the file or tells some programs how to load it.
this is what TXPHAROAH cautioned us to see
So its not only the AC3 audio that makes a re-named VOB unusable in many programs other than TMPG..
its the fact that you merely renamed the file, not actually "CONVERTED IT" though the conversion in this case merely consists of changing the header

dcsos:

the original poster in this thread asked the question "Any programs or ways to convert the vob in the DVD to mpeg2 preserving the original bitrate?"

That is the context of my response....it was to that question. I didn't say my method was the best or anything of the sort. But it does "preserve the original bitrate"

You may also want to read how Txpharoah stepped on my response....it was a little too assertive about a process that I have used for myself.

I didn't offer this as a guide, simply gave the original poster an option to what was specifically asked.

I'm sure you're probably right about headers and such....but I'm also right about my process because I have 5 or 6 DVD's I've burned with perfect audio sync using what I mentioned as one of the critical steps.

Hey it can't hurt to try..
all these guys who say NOPE are a problem, huh?
I just say..look out below!!!!!!
Good going MMASW

There are times when I want to re-edit the video files on a recently burnt DVD-R. Using DVD Decryptor I rip the vob files from DVD-R to HD. I then use VOBEdit to Demux these Vobs with the options of Demuxing Multiple Streams at Once. I tick Demux Video, and Audio and also tick Split on New Vob-ID.
This gives me a series of M2v (video) and mpa (audio) files.
So far, so good.
BUT whenever the original DVD Mpeg2 has been over a certain size (say around 1.5 gb) then the VobEdit Demux gives me 2 video and 2 audio files (sorta like part1 and part2) for that particular DVD file.
Now lets say I want to add Chapter points to these two M2v and Mpa files, and recompile. For some reason, part 2 Audio is always lost. It is silent. To try and determine what is wrong, I fed the Part 2 video and audio files to MainConcept Encoder. It was happy with the video, but reported "no audio data", which was no surprise, as I certainly could not hear the audio either. (Part 1 plays Vid and Audio perfectly). And yet if you play Part 2 Audio mpa file in WMP, you can hear it OK. WTF !!! ???
So....How do I recompile with Audio all the way through??

TIA

Have you trie DEMUXING with VOB EDIT to the
PCM audio choice..
This would give you a .WAV file at 48,000
maybe It would just output one long one OR,if you have part 1 and 2 again
This would be easier to join with the later segment than an MPA file
