Extra chapters after joining clips with VOBedit?

[scorpio61]

I was attempting to put all of Band Of Brothers Discs 1 and 2 on 1 dvdr, and hoping the quality is not too diminished. I ripped the movie only from both discs. Ended up with 6 VOBs and 12 chapters for D1, and 6 VOBs and 12 Chapters for D2. However, when I joined them following the guide, I ended up with 11 VOBs and more than 24 chapters. I had IFOedit create the new IFOs after joining. The disc also stops playing about 80% through the movie. I had the same problem trying to combine Godfather II disc 1 and 2.

Anyone else experience this or have any suggestions?

Thanks!

Hmmm...

I believe the DVD specs call for a limit on 9 VOB files per Title Set. These VOBs are limited to 1 Gb or less in size but you still have a 9 VOB limit. So if you created new IFOs,it was probably reading and configuring for 9 VOBs. That may explain your extra VOBS, 10 & 11, as your 20% loss.

VOBS or vob files? You can have up to 99 vobs per titleset.

The extra chapters are caused by the cell structure. Each cell is considered a chapter when creating ifo's with IfoEdit. On authored DVDs quite often a chapter will include more than one cell. You can edit the PTT later to reduce the number of chapters by removing entries that should not be chapters.

Sorry mpucoder:( Your quote disturbs me. The maximum per titleset should be 9. 10 if you count the menu VOB. Am I on the same page as you? Here is a typical 10 VOB titleset.

VTS_01_0.BUP
VTS_01_0.IFO
VTS_01_0.VOB
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB
VTS_01_4.VOB
VTS_01_5.VOB
VTS_01_6.VOB
VTS_01_7.VOB
VTS_01_8.VOB
VTS_01_9.VOB

There can never be a VTS_01_10.VOB and beyond. Even the file name is not in DVD specs. To ensure maximum compatibility, DVD-Video file names should consist of no more that 8 characters and optionally followed by a ., and optionally followed by no more than 3 characters. Hence, the example above is in specs.

Now, you must be talking about titles as the maximum you can have is 99 and each one can be in its own titleset too. ie VTS_01_* to VTS_99_*.

As for chapters, which is a division of a title and technically called a part of a title (PTT), you can have up to 999 chapters or PTTs per title. Since a single cell can be associated with a single chapter so it's logical to say we can have up to 999 cells.

I might be brainfarting right now but after rereading the DVD Specs, it still didn't jive with what you mentioned.

The extra chapters are caused by the cell structure. Each cell is considered a chapter when creating ifo's with IfoEdit. On authored DVDs quite often a chapter will include more than one cell. You can edit the PTT later to reduce the number of chapters by removing entries that should not be chapters.
I agree with you here as stated by scorpio61, there supposed to be 24 chapters and obviously there are more now. Since IFOupdate can't be used here, he must manually edit the IFO.

I asked "VOBS or vob files?" A vob is all the cells with the same VobID, and there may be 99 per titleset. There may be only 9 files that contain them (vob files).

Now, I'm assuming scorpio66 meant vob files, and his 11 files definitely is a problem, and probably the reason the playback stopped at 80%.

[scorpio61]

Yes, I did mean VOB files. I started over again, this time, I used DVD2ONE to take the 6 original VOB files with 12 chapters each, down to 5 VOB files each. So now at 10 total VOB files, I thought I would be ok. However, after joining with VOBedit, I end up with 9 VOB files, but 32 chapters. 8 more chapters than I thought I should have. The good news is, it does play to the end with no hangups.

Time to manually edit...

Thanks,

Scorpio61, 66, whatever it takes. :)

scorpio61 has repeatedly said he used VOBedit to join the VOBs, theres the Extra Chapters BUG. VOBedit used in JoinClips mode will Automatically increase the VOB ID counter upon loading the next VOB. Which will translate into extra chapters using IFOedit to CreateIFO's, when you choose - Create 1 PGC. Since you will have as many extra chapters as you have VOBS. Hopefully, I will finish a little tool to help overcome this problem. A simple fix, is to append all the VOBs together into 1 massive VOB, then use IFOedit to create your IFO, it will cut the output VOBS to 1 gb in size. Hope your on a NTFS file system.

Not a bug, it is intentional. It's just that this use (joining sides) was not foreseen. You can either join the vob into a huge one, as suggested, or split it by VobID before joining clips.
But it is also true that multi-cell chapters will become additional chapters.

[scorpio61]

Actually, I had 8 extra chapters.. which doesn't correlate to the number of VOB files. Perhaps I will re-rip the disc and just create on file. Then join the two files, which should result in only one extra chapter. Hopefully removing that one chapter would be easier than removing 8 chapters.

Any idea when your tool will be ready?

Thanks,
Scorp!

Ummm, how would I do that?

[VidHack]

The trick to make this work is to insure you only feed VOBedit 1 single massive VOB. If you rip the movie down as 1 massive VOB, set the output size to some huge number (Say 8gb). For example, use Vstrip, set size to 8gb, then rip. Or use vStrip after you ripped it to your drive, just use it in APPEND mode to join all the vobs of the titleset into 1 massive one. Just load up the VOBS you need to join - then APPEND. It will output 1 massive sized VOB. You then feed that VOB into VOBedit. You see, now that you feed it only 1 VOB, you wont get any fake / wrong chapter points added.

The problem is, there are two seperate dvd's. So I wind up with two masasive vobs. This worked better, now I only had one "problem area" after the join and split. But it bugs me because it throws off the chapters from that point on, even if I manually modify them.

I was finally able to merge the vobs with the File Merger tool listed in Doom9's Useful Software section. I am running it through vobedit join clips right now. (Theoretically) I'm set! Thanks for being informed enough to warn about the vobedit join bug/feature. And thanks for all your help!
