DVD - VOB to WHATEVER

[PrinceOfDarkness]

Hello!

Well, I'm trying to convert the VOB files of a DVD (I dont know where it came from or how) to a easy format and a light one. I have used DivX Plus converter and it did the job very well except...(dramatic pause)... for the AUDIO SYNC! Ok guys, I'm almost getting CRAZY!! I dont understand very well about video|audio codecs, I would like to learn more about it but sadly I have no such time, I already found some similar topics but none of them resolve my problem. I just want to reduce the file size of this crap shit of dvd but the audio get out of sync, seems the start its ok, but when it get about the content of the 2 or 3 vob file, the audio problem starts.

Here is the mediainfor file:

Please help guys, I would be very thankful and would give a kidney for it.

You shouldn't convert each vob separate. YOu should always try convert the entire dvd at once. I have no idea if divx plus converter can do that but check if you can open a dvd folder/video_ts or a .ifo file.

Or else try convert to avi divx/xvid with the old autogk or convert/shrink to mp4 with handbrake / vidcoder.

[PrinceOfDarkness]

wow, thanks for the fast reply.

I already did it. I already tried autogk, vob2mpg, dvdfab 8, xvid4psp but all give the same problem. I think the problem is when the program join the vob files, maybe theres a specific program to join the vob into one archive than i could convert it with the autogk?

Try joining the separate VOB files with VOBMerge before converting.

Or go into a Windows command prompt and use the old DOS command, which I've used a few times myself:

copy /b vob1.vob + vob2.vob + [more vob's...] joined.vob

The "/b" parameter specifies that the files being joined are binary files, not text. The vob file names are joined with "+" between each name. The last part of the statement is the name you want for the joined .vob.

This won't take too long to run but remember that you are literally "copying" several files and creating a new one, so give it some time. The only time it didn't work was with vob's from a weird nonstandard Chinese DVD. For that, I had to use TMPGenc MPEG Editor.

I have joined the vob files. When i play the 4,16Gb vob file I get no problem, just the total lengh are showing 00:00:35 despite the video duration is about 01:17:49. But again, when i try to convert it, i get the same audio sync problem. I think the problem can be with some contents of the DVD itself, there are some separete sections that show images like a slideshow without audio, and when i play the joined vob file i get this contents playing too.

Is there a way to simply reduce the dvd size leaving the structure intact? I just want to reduce the size to about 700 mb.

Try converting again your joined file but this time force it to convert to 23.97fps even though the media info file says its 29.97fps. Unless your converted version is already at 23.97fps, if so force it to be 29.97fps.

...there are some separete sections that show images like a slideshow without audio, and when i play the joined vob file i get this contents playing too.

It sounds to me as though you've joined a menu VOB or two in there as well. If you can give us the exact file names of the VOBs you have, we can take an educated guess as to which ones to join and which ones to leave out.

There will most likely be at least a few of 0.99GB in size. You need all of those. You'll most likely need one other too. That will have the same file name structure as the 0.99GB files but the last number in the file name will be one higher than in the last 0.99GB file name.

If I'm confusing you even more with this info, just list the filenames.

One image is worth a thousand of words...




I've joined the last 5 files. The "slideshows" that I've said is in the final of the VST_01_3.VOB and VST_01_5.VOB.



The slideshows are the "Expression Drawings" "Expression Drawings2" and "Other Products". The other two are the video files, the "Lecture" are in the VST_01_1, 2 and 3 while the "Expressions" are in the 4 and 5.



Thymej, which program do you suggest to use? I've tried autogk and it dont have fps option.

[Slipster]

I see. I was expecting this to be a normal movie DVD structure where the VOBs you've joined already would have been the right ones all along. I'll just sit back and learn from this point on.

That's so you can't screw it up. It knows how to determine what the framerate is supposed to be.

How many titles are in this thing? If more than one, in this case you can't treat all the VOBs together as if they're all part of one giant single video (because they aren't).

One way to find out is to open the DVD in VobBlanker, click on the VTS_01_*.VOB, and see if more than one title shows up in the lower window. Better yet, post a VobBlanker picture after you do that.

This is what a DVD with multiple titles looks like:

3 titles to be exact(3 music videos). The OP's screenshot looks like a normal, single title DVD to me.

This is what a DVD with multiple titles looks like:

Not necessarily. Separate titles are often found within the same VTS. I don't know for sure that's true in this case, but I think it is. Here's an example:

You're possibly opening the wrong vob files or the disc was badly ripped, but while some conversion programs will let you open a "whole" DVD, pick the movie or episodes to be encoded and you're good to go, many of the free encoders expect a properly "prepared" DVD which they can then encode. So to give them one:

Open the ripped DVD files using DVDShrink, or open the DVD directly. You may need something like AnyDVD or DVDFab running in the background doing the decrypting to open protected DVDs directly, but it's a better way to go about it as it reduces the process by one step.
Go into DVDShrink's preferences and set the target output DVD size to at least DVD9 so DVDShrink won't try to "shrink" the video.

With the ripped files/DVD open in DVDShrink use the Re-author button. In the right pane there'll be a bunch of titles. If it's a movie DVD there'll probably be one title with a duration long enough to make it obvious that's the movie. Drag it from the right pane to the left.
If it's an episodic DVD there'll be at least one title for each episode. You may have to select each title and use the preview window in the bottom left corner to work out which is which (title 3 could be episode 1 etc). Drag each episode's title from the right pane to the left.
(I think very occasionally I've come across an episodic DVD where there's a single title for all episodes, in which case the process would be to drag the title from right pane to the left pane multiple times.... once for each episode..... then each title can easily be edited down to a single episode by selecting the appropiate start and end chapters, but it doesn't happen very often)

Use DVDShrink's backup function to backup the ripped files to a new location on your hard drive, or if you've opened the DVD directly back it up the same way. When you're done.....

If it was a movie DVD you'll have a folder full of ripped files which look pretty much like the pic in PrinceOfDarkness's post #9. Using AutoGK you'd normally open the VTS_01_0.IFO file. Some conversion programs may make you open the first vob file instead (VTS_01_1.VOB). That's okay and perfectly normal. The program will (or at least it should) include the rest of the vob files in the process. If the DVD was ripped correctly it won't cause audio sync problems.

If it was an episodic DVD you should end up with a bunch of ripped files which look basically the same as the pic in hech54's post #12. Each IFO file (or the vob files which follow) will be an individual episode ready to be encoded. In the case of AutoGK you'd open and encode each IFO file individually (not including the VIDEO_TS files which can be ignored).
