Dvd Rip ?

[sepehr_s]

Can u tell me what is the best format ( best quality ) for ripping DVD's ?

[Nitemare]

The question is tricky. A straight DVD rip will transfer the data from the disc to your hard drive. The files will be in the VOB format.

You can also convert to another format. The "best" format depends on what you want to do with the video once it's ripped.

For instance, if you're copying little Joey's birthday DVD and want to make copies for other people, a staright rip to VOBs and burn to blank DVD is best. If you want to e-mail the video to Aunt Marge in Alaska, ripping and then converting to xvid AVI or WMV is "best".

Just to get the nomenclature right: Ripping a DVD is the action of getting the encrypted DVD to a decrypted version of the same, most often located on your HDD. Once this is done, you can encode it to some other format, which I suspect is really your question. And as Nitemare says, what is best depends on what you want to do with it, and what you want it to play on.
Objectively, the best quality is the rip, without further processing.

yes you're right I mean what is the best encoding format for DVD's for high quality ?

[mats.hogberg]

Still: The original, (just ripped) for computer and standalone playback.

Maybe he means Divx or Xvid? If so, all of these will reduce quality to a ertain extent. Best is a direct rip to your HD With any ripper such a DVDDecrypter.

Something like h264 may be even better, for AVI.

I have a similar problem.

I use my HDD DVD Recorder to capture my VHS and then burn them onto DVDs for archiving at various quality settings. What I am trying to do is to then rip them into a file format that I can store on my harddrive. I am hoping to do this without re-encoding the data as it would introduce a loss of quality.

As they are non-copy-right material, I can copy the vob files onto my harddrive with no problem. But would that be the best format to keep them?

Isn't DVD video encoded in MPEG2 anyway? Can't I just somehow convert the VOB back into MPEG2 files in whatever quality they had been recorded without having to re-encode them again?

I have look into various ripping and encoding softwares but they all seem to re-encode the whole file again. Not only this would probably degrade the quality, I would also not be able to select the most optimal settings to use when encoding.

Any help would be greatly appreciated.

paradox148,
Let me pass along a very simple point of procedure that thread jacking is kinda rude. It would be better to start your own thread even if it was similar.

Waiting for your new thread.

[paradox148]

I do apologize if what I have done is considered rude in this forum.

To my understanding, my question is in fact what the original poster was asking even though my setup is a little different that I am using my own recorded DVD.

I believe what the original poster was asking was what format the DVD should be ripped in order to preserve it in its best quality state which is exactly what I am trying to find out.

I did consider posting a new thread(in fact it would have been easier) but I thought it would be to the benefit of the original poster and other members to be reading about essentially the same topic within the same thread rather than having multiple threads repeating the same subject.

Well, as it's a pretty recent thread, and rather the same q, it's OK by me.
Yes, mpg2 is the main ingredient in a VOB.
I'd rip the DVD to HDD with DVDDecrypter, IFO mode, set file splitting to None.
Then run the resulting VOB thru VOB2MPG to get it in mpg format. No reencoding, exatly the same data as in the VOB.

paradox148,

As mats.hogberg pointed out earlier in this thread, the term "rip" means to remove copy protection from a dvd. In your case, you're not really "ripping" as much as just copying or moving the unencrypted files. It's not a big deal, but it helps to get or give help if we're all using the same terminology.

As to your question, if you copy all the files (VOBs, IFOs and BUPs) from one of your dvd-recorder produced disks to your hard drive (just using Windows Explorer), you can use any software player to watch the material straight from the hard drive with the best quality possible, and the least work. Even freeware programs like Media Player Classic will play it.

If you want the video to be in a single file, with no menus, chapters, etc., while retaining the best quality possible, you can use something like Vob2Mpeg to extract the mpg from the dvd files.

You can also convert the material to other formats, if you prefer, but there will inevitably be some measure of quality loss, the amount depending on how compressed you need the file(s) to be. It depends on what suits your purpose.

I see these were your first two posts here, so welcome to VideoHelp.

Thankyou Thankyou Thankyou!!!

Vob2Mpeg is probably exactly what I have been looking for!!!! Been trying to work this one out for ages! You guys cannot begin to know how much this has helped me!

(It took me years after trying many free/commercial re-encoding programs.to realise that with the DAT file in VCD's, all I had to do was to change the extension from .dat to .mpg and viola! it is a standard mpeg1 file! Duh!)

Eternally grateful for the pointer!

extracting is the word, not ripping....

Err.... No. That'd be about the same as turning VOB into MPG just by altering the extension. See this. You should use VCDGear for VCD to mpg.
Some apps will treat a renamed .dat as a true mpg, just like some apps will treat a renamed .vob as a true mpg - but don't take it for granted.
