Have VOB files from DVD. How to make them all one file without losing quali

[mindstormer]

I have VOB files from a DVD. I want to make them all one file without losing quality. I know that I can't combine the VOB files, but can I convert them to another format without transcoding (without sacrificing quality)?

Thanks.

P.S. On an unrelated note, I was wondering why SUPER converter's feature "convert without transcoding" is not popular in other converters because it seems like a "must-have" feature... being able to convert a video to a different format without sacrificing any quality... is that even possible?

No (they WILL lose some quality with a reencode), but the quality loss might still be acceptable to you. Plus, is might be possible to join/combine the clips if ALL their encoding specs are the same.

Convert without transcoding = remuxing. That is all it means, and that might have limited use to you.

You should start over from the dvd itself. If you have anydvd you can use dvdshrink regardless of how new the protection is. Go to preferences and select "don't split into 1gb chunks". Then when you rip it you will get the main movie in one giant vob file. You'll have the bup and ifo files associated with it but you will have the movie proper in one self contained vob file.

There might be other ways to do it with the files already ripped on your computer.

I suppose there is no reason you can't use dvd shrink to "open file" and then point it at your ripped dvd folder on your computer. You should then be able to "rerip" it to another folder - just be sure to go into preferences and make sure "1gb chunks" is NOT selected and you'll get one large vob file.

There might also be a way to do a iso mount with a virtual iso program but I have only done that a handful of times so I can't name programs or steps to do it that way with the files already on your computer.


Edit - than you can convert your single large vob into whatever you want.

Now cornucopia is right if they are vobs from different dvds you might run into problems with specs and resolution and pal/ntsc issues depending on where your dvds come from. But if all you want is to work with a single dvd than the suggestion above is good to go.

You could try VOB2MPG to repackage the video and audio to an .mpg container without re-encoding. If all the VOB files are in the same VOB set from the same physical disc, it should work.

I know that I can't combine the VOB files...

You know wrong. VobMerge, Vob2MPG, even decrypting to a single VOB as described earlier, or when using DVD Decrypter if it'll work on your source.

... being able to convert a video to a different format without sacrificing any quality... is that even possible?

Not unless it's being converted to a lossless (and very large filesized) AVI.

i few times about 6 or 7 yrs ago, before i was told it couldn't be done

i simply copied the vobs, and changed the file type from vob to mpg, then joined them with an mpeg editor

like vdub or videoredo , it worked for me

you can join them with super, IF they are sequentionally numbered, either vob or mpg

[mindstormer]

Nice. Thanks for the information, guys.

Very easy, install MakeMKV ..... its free

http://makemkv.com/

It will take any DVD/blu-ray source and convert it to a single MKV file without loosing any quality

It has the added bonus of also splitting episode DVD/blu-ray and also auto-joining the annoying blu-rays thats have hundreds of small files instead of one file. But I did find out this way that there is different version of gore for films depending on what age rating you choose is watching it

Alien vs Predator was a prime exmple, choose the 18 version and all the gore is there. Choose less than 18 and some scenes are replaced with a lot less blood splashed around. And that blu-ray has hundreds of tiny video files

"VOB" uses the MPEG-PES (packetized elementary stream) type of container. "MPEG" or "MPG" usually means MPEG2-PS (Program Stream) container, though some might mistakenly refer to MPEG1-SS (System Stream) or MPEG2-TS (Transport Streams) or even MP4 as an MPEG container. However, none of those are identical to VOB. Think of Vob as a "Super-container", because items can be placed in it which are not allowed in MPG2-PS or similar. For example: LPCM Audio. OK in VOB, won't normally work at all in MPG. You usually won't even be given the option to allow LPCM to be added.

Likely, your player/editor application (be it hardware or software) was forgiving enough to ignore the differences between the 2 and just pull out the relevant V+A streams as needed.
THAT DOES NOT MEAN THIS WILL WORK EVERY TIME, OR FOR EVERY ONE.
You just got lucky.
That's why one should go the extra mile and use a program like Vob2Mpg so you are left with a CLEAN, MPG2-PS type container (the kind MOST people expect to be working with).

Last I checked MKVToolnix still can combine vobs into one .mkv file. I do it all the time, within the last 4 weeks even. If you already have the decrypted DVD on your hard-disk, just drag the first vob file in the set to MMG, uncheck any subs or audio's you dont want and start muxing.

I remember in the past taking some VOBs from a DVD I had made, not a professional copyrighted DVD and taking the VOBS and dropping them into Mpeg Video Wizard on the timeline. I remember where each VOB met that there was a glitch in the video at that spot. So I did some research here at videohelp and used DVD Decrypter after that. I can extract the whole VOB in one piece.

the OP doesn't ask about mkv
why do so many replies mention creating mkV

Maybe because what he asked was:

I have VOB files from a DVD. I want to make them all one file without losing quality.

and sticking them into the MKV container answers the question. It's nothing I'd do myself, and probably not what mindstormer had in mind when he asked the question, but it's a valid answer.

And also asks "but can I convert them to another format without transcoding (without sacrificing quality)?" which is exactly what MakeMKV will do

If he insists on using a single VOB, then this should do exactly what is being asked
