DVD to original MPEG bitrate conversion

[dsl25]

Is it possible to rip the original MPEGs from a DVD to my hardisk?
I mean the MPEG files with their original bitrates, as stored in the VOBs, without converting them in lower bitrate or another format.

thanks for any help!

It sure is.
As you said, the MPEG is inside the vob files, so you only need to rip the VOB files, and then extract.

You can do it in a single go with DVD Decrypter, in IFO Mode. You choose which video you want, and DVD Decrypter will rip and demux video and audio. You will get one video and one audio stream, which are unaltered.

Thanks a lot for your help!

Will try with Decrypter in IFO, but would it be possible to obtain a single mpeg file, including the audio+video?

I think DVD Decrypter does not output multiplexed streams, so once you have the video and audio streams, just use a program like TMPGEnc, bbMPEG, ProjectX or whatever to multiplex these two streams to obtain one MPEG program stream.

Neither multiplexing nor demultiplexing alters the video or audio streams in any way. All it does it to connect multiple streams to one, or separating them.

Thanks again!

Sounds good: tested both and in fact TMPGenc can do it alone (if you don't need to decrypt). It saves first a mpg file on the hard disk and then offers to convert it in another muxed file based on encoding settings you might need to add.

cheers!

Hi,

I signed in today to find out this very thing. When you say, "TMPGenc can do it alone ", do you mean it also will rip from the DVD and convert audio and video to a single mpeg file? I think you were asking about the same thing I am interested in, or close. I want to create an mpeg file - in this case a short clip of part of the movie - from a commercial DVD.

Thanks,
Gary

do you mean it also will rip from the DVD and convert audio and video to a single mpeg file?

That can be done, too, but that is not what dsl25 wanted. He wanted no conversion at all.
Conversion means quality loss, so whenever possible, avoid it.

TMPGEnc can not decrypt CSS, so you have to take care of that by using a DeCSS program like DVD Decrypter, AnyDVD, or whatever.
TMPGEnc has in File > MPEG tools a multiplexer and a demultiplexer. The demultiplexer allows you to load the VOB and extract video and audio to separate files (without converting them). Using the multiplexer you can create a single MPEG file out of them.

But DVD Decrypter can do more, and that's the advantage. The VOB is max. 1 GB in size. Without DVD Decrypter, if the part you want to rip is not in a single VOB, you first need to connect the VOBs together. And if there are many streams in one VOB, you need to cut out the part you want.
With DVD Decrypter, you can just select the part you want (as they are all enumerated inside the VOB), and DVD Decrypter will extract the part you want, you don't need to do anything with the VOBs before.

Once you have the Elementary Streams (that's the separate video and audio streams) you can use a tool like Cuttermaran or MPEG2Schnitt or similar tools to cut the MPEG.

The above is perfectly correct.

I only would add that TMPGenc 3.0 Xpress is a little bit strange when launching because it doesn't offer to open VOB files from the main menu "add files". Instead, you have to use the "source wizard" in order to open root DVD files or decrypted VOB files.

The first result from there is that you obtain a .mpg file which is unaltered and the program offers you then the option to convert it to another format if you want. You also have the option to obtain two separate files (audio/video) instead of a single one.

In my case the first file was what I needed.

- Note that TPMGenc version 2.5 doesn't work the same way and it doesn't seem possible!

Well, I got this to work using DVD Decrypter and TMPGenc 2.5. After running Decrypter, I looked through the vob files until I found the one I wanted, then selected it in TMPGEnc. It created a 1.7 GB AVI file with both audio and video. I then edited out the clips I wanted using Adobe Premier Pro, and exported them as individual movies. At that point, the clip size was still too large to send in an email as intended, and unfortunately my PC would freeze when I would try to encode in Pre Pro. (????) I was finally able to do the encoding in Windows Movie Maker, of all things!

Thanks a lot for the help!
