VOB time length issue

[end_user]

Howdy,

I have a strange problem with a VOB dvd file that i've extracted for a mp4 conversion. in the file properties it indicates that the "time length" is 25 hours for a 330Mb file.

All of the VOB files from this particular dvd series (10 discs) are encoded like that. The 1st 3 to 4 VOB files, the 0.99Gb ones have their properlenght time (16 to 19 min.) but the last BOV file has that problem if you will.

And whenever i try to encode the file to any other format, it shows an staggering 80Gb for those particular VOB files (i've tried video redo, xilisoft video converter, adobe media encoder)

So my question is, how do i fix it? is there any way to correct the time length for those files? I'm new to the video editing world so you have to excuse my lack of knowledge for the tools and terminology.

Cheers.

Use DVDshrink to re-author a DVD with only the implicated episodes. I hope you don't need subs, the trimming will shift the timing.

This is a common error that many people make. VOB files are not like other media files (AVI, MP4, MKV, etc). They are NOT supposed to exist on their own, but ALWAYS as a part of a DVD file structure (*.IFO, *.BUP, *.VOB).

When you deal with a VOB outside this structure, strange things will happen like, drum roll... bad timing.

If you want to convert a VOB, don't. Instead, convert the DVD structure where it's supposed to be.

It might be useful to be more specific about "this particular dvd series". Is it multiple episodes like a TV show or some kind of animation? Then you really shouldn't be converting by VOB as Keyser points out. DVD has a limit where each VOB file can only be roughly 1 GB in size, so most of the time the video gets split exactly at the 1 GB spot and you might actually be in the middle of something at the split point.

Perhaps the simplest thing for you, assuming it's episodes/animation, would be to use old DVDDecrypter to split by IFO. Note that I said IFO and did NOT say ISO. You can search online for guides on using it to split by IFO. Do note that DVDDecrypter is old and was abandoned many years ago by its creator to settle a legal dispute and as a result it cannot correctly rip some discs. Usually this only applies to some region 1 (USA/Canada) DVDs. If you have ripping problems with DVDDecrypter then you can't use it. Disney and Sony DVDs are the most likely to fail to rip using DVDDecrypter.

Also, have you tried using Handbrake? It can rip and encode to MP4 and it might be easier for you to use than whatever you've tried so far and possibly easier than my DVDDecrypter idea.

It's called "copy protection".
