Resizing video in VOBs

[keithmac]

I`ve ripped a dvd into vobs and found the video to be 480x480 at 29.97fps. The problem is it`s not compatible with normal dvd players (or so TMPGEnc DVD Author tells me).

Is there an easy way of manipulating the video to re-size it and make it compliant (352x480 or 720x480)?.

I`ve ripped it out to an m2v file to try and re-size it using TMPGEnc, but that tells me I can`t import m2v files. What program can?

If I can get an altered m2v then I think I can fumble my way through!

If it`s a stupid question then I don`t mind being told so, but I wouldn`t mind a bit of help all the same!

hi and welcome to the forum,
first of, i'd like to know where you got this 480x480 m2v/vob file from? was it from a dvd which played in a standalone player, or was it from some other kind of media (maybe SVCD?!)
furthermore it would be good to know what your final goal is. do you want to make a main movie only copy, or some other task?

this information will help us to determine if you are using the right (easiest) method. :)

unfortunately it is not possible to resize your video without reencoding - which again means loosing more quality. if you still want to resize, i think it would be smartest to just remove the black bars on the top and bottom of the picture so that you get 352x480 - provided of course the original movie contains those ;)

hope this helps

Why do you want to re-author the dvd? Some dvd players will actually play back 480x480 material, provided the audio is 48kHz.

There is a guide by doom9 on how to author svcd material without reencoding the video: http://www.doom9.org/mpg/svcd2dvdr.htm .
If you have problems playing such a dvd, try repatching the authored vobs back to their true resolution before you burn. Burn on rw first :).

Hello and cheers for the replys :) .

I`m trying to do a multi movie dvd, using this film and another. I`d like to use TMPGEnc DVD Author and this is where the problem lies.

I ripped the vobs from a dvd-r which plays in a stand-alone player. looking at the size I also thought that the original video may have been from SVCD the size is 1.51 GB.(3 cd`s?).

If there`s any other program that`ll let me create a multi film dvd with this non-standard video then I might give that a go, I don`t fancy re-encoding due to the quality issue.

I take it that even if the file size is the same the quality will still be worse by a big margin?

The only authoring tool I know which would even look at 480*480 material is ifoedit.

I have to apologize for a typo in my previous post - the doom9 guide is of course without reencoding the video :) ...

NB: 1,51 GB is more like a 2 CD-rip ...

Looked at the svcd guide last night, seems a good idea fooling DVD author into thinking it`s compliant and then changing back after authoring, will give that a go first.

Cheers.

I can second that,
it's definitely a 2 CD SVCD rip then :)

get restream and patch the headers of the video to 720x576 or 352x576 so that u fool a dvd authoring program to import it.

[keithmac]

Right I`ve used DVDPatcher to fool DVD Author and I`ve ended up with a proper video_ts folder with menus and the lot.

I`ve gone into this with DVDPatcher again to re-patch the original values back in. (I take it TMPGEnc DVD Author just writes the VOBS with little or no modification?)

I`ve found 1 vob has no sequence header so I`ll have to sort that out.

If I change all the headers back after it`s been authored will I have to do anything else or just burn it to disk?

Will burn one later to see if it works.

Cheers.

instead of burning a DVD and risking a coaster, i'd use Image Tool Classic to create an iso file and then mount it with deamon tools... this way you might save yourself a few blanks and quite some time too. :)

Cheers for the tip.

I burnt a disk and tried it. Menu works fine and films play but 2 of them (1.5gb a piece) the audio goes out of sync after 1 hour, I`m going to have to see weather I`ve fed dvd author duff vobs, or it`s done something to them while authoring?

I think I`ll start writing images first to save some money!:rolleyes:
