VOB Numbering

[GParent]

In the process of joining the two halves of THE GANGS OF NEW YORK, I noticed that the total number of VOBs is 10. While I did not have a major occurrance with IFOEDIT, I was concerned about VTS_01_10.VOB. In fact, I did have a Chapter problem with the newly joined 10 VOB set, but a re-stream down to 8 VOBs seemed to correct it. I still don't know if it could have been that 10th VOB or something else.

Question:

Any warnings, red flags, or concerns about the numbering of VOBs and/or how many VOBs that IFOEDIT can handle?

The DVD specs require that your filename be 8 characters long, followed by a period, and then followed by a three character extension. e.g. VTS_01_0.IFO, VIDEO_TS.BUP. Notice that "VTS_01_10" is 9 characters long? Have you ever seen a VTS_##_10.* or higher on any commerical DVD? I haven't.

As for your chapter problem, your chapters will only go to the max size limit of a DVD-9. It'll cut off when it reaches this threshold. So now, "exactly" how big was your joined movie without it stripped?

I also have not and thanks for your referencing the specification on filneame size. It was never my intention to actually create a DVD using a 9 character VTS_##_XX name. All I was interested in learning is IF the IFOEDIT and VOBEDIT programs accomodate this relaxing of the name convention. Why? When you join a movie that spans two discs, you have the potential of getting 10 VOB files. In the case of Gangs of New York, the 5th VOB on each disc is small enough where a restream takes care of the numbering problem. However, I had to first generate IFO files from the 10 VOBs.

Because IFOEDIT did not throw an exception or give a warning, I assume I was within bounds.

Guess they are going to have to drop the UDF/Bridge format for DVD2 then. If your VOB's are split at 1 gb and there's only one digit for iteration, 10.0gb is the limit; good for now, bad for later.

UDF/Bridge took a few years to catch on, and it was a rocky road on your standard OS to make it work consistently back then. Guess this means that we will see another wave of incompatibility and shotty dependability in the next DVD format for sure.

Also means that BluRay (if used to create *large*) DVD's would have to split an HD-DVD down to multiple VTS's every 10 gigs to be compatible with the existing software players/standards.

Retch, bah, ick, bloody marketing tactics.

VobEdit uses a 3 digit sequence number for joining vobs, eg vts_xx_yyy.vob

8.3 filenames can still accomodate more than 9 1GB vob files much the same way hexadecimal numbers are represented, by using letters. This is not to say the current spec allows this, it does not, but the future spec, which is nowhere near ready, may.

And I'm surprised a hex guy wouldn't think of that :)
