View Full Version : Cannot get celltimes from 1 vob with 22 Pgcs

I am converting my Original video dvd "Garbage Absolute" NTSC from Lpcm to Ac3
audio and I have run into a problem. I demux and convert the audio fine. But when I
go to get the celltimes for the original chapters using either Ifoedit, PgcDemux, or
ChapterXtractor. I can only get the celltime for 1 of the 22 Pgcs at a time. In the movie
there are 22 Pgcs and 28 cells. When I have converted other dvds in this way. I would
select the first VTS_PGC and grab the celltime and it would do so for the whole movie
that I was converting. But with this dvd, it is only grabbing the celltime info for 1 Pgc at
a time. Which of course doesn't properly encode the default chapters and menu of the
original movie. Pgc1 points to the first video of the movie and is 4:30 minutes long. Pgc7
is the rest of the videos and is 59:30 minutes long. Pgc 22 is the behind the scenes
movie and 79:00 minutes in length.

I have tried grabbing the celltimes for all 22 Pgcs and then manually combining them.
But I have no idea of how I should combine them. I will list the celltimes for the first 7
Pgc's to show you what they look like.

Pgc 1
8106
8136
Pgc 2
15
30
45
60
Pgc 3

Pgc 4

Pgc 5

Pgc 6

Pgc 7

73515
80776
86541
92817
99793
107107
107137

and so on, with many of the remaining Pgc celltimes addressing similar locations. I was
unable to find this problem or a solution on this or other sites. If it has been addressed
before I would be very grateful to be pointed to the correct post, or any suggestions.
Thanks for considering this.

P.S. Since I cannot post a question for 5 days, I have continued to research and to work
on this problem. One useful post that I found,
http://forum.doom9.org/showthread.php?t=80899
suggested removing the original VTS_01_0.IFO from the rip directory and then having
Ifoedit make a new one, this time to make the movie as 1 Pgc rather than multiple ones.
And then you can get the celltimes for it all. This was a very promising idea and I tried it.
It mostly worked, in that the remuxed movie now had the original chapters and was
properly synced. But when reinserted into the original rip with Vobblanker the chapters
were all messed up and they didn't point to the correct locations or videos anymore,
and the menu was now inaccessable. I believe the problem is that the original rip movie
is 22 Pgcs and the remuxed one is only 1 Pgc. I have tried replacing the remux video
into first the original rip with the original ifo files. And then into the original with the new
ifo files made with ifoedit that made the movie into 1 Pgc. Both produce the same
problems mentioned above, messed up chapters and no menu access.

What I need is a method that will get all the celltimes from the 22 Pgcs and properly
duplicate the original menu. Or a method that will adjust the original menu to now
reconize and work with the edited movie as 1 Pgc.

Why am I doing this? The original dvd is cheap and flimsy and so I want a backup that
I can use instead. I need to archive to dvd5 and so I need to convert the wasteful
Lpcm to Ac3, which saves 1.1G space before shrinking to dvd5. :thanks:

Hi!I need to archive to dvd5 and so I need to convert the wasteful Lpcm to Ac3, which saves 1.1G space before shrinking to dvd5Most audiophiles would prefer to retain the higher quality LPCM audiostream and either sacrific e some video quality or simply split the DVD onto two DVD5s...

Did you try to use the menu editor in PGCEdit to redo the navigation commands?

I'm certainly not an audiophile and cannot tell a difference between LPCM and AC3. The video quality is more important to me in this case. After trimming unneeded things like warnings, logos and such the m2v is 5.2G in size and the LPCM audio is 1.42G, and is just slightly to large for Dvdshrink to shrink it to dvd5. If I keep the LPCM I'll have to shrink the video 45%, converting to AC3 I only have to shrink it 25%.

Splitting it to 2 dvd5 would be acceptable, but I don't even know where to begin with something like that. How do I extract half of the videos and audio, and then how do I remove the menu selection for the missing videos, and correctly point the menu to the remaining videos? I have looked at Pcgedit (thank you for that suggestion) and it looks like the kind of tool needed to fix the menu. It is also quite a bit above my current skill level with menu editing.

After looking at the original rip menu with Pgcedit. I see that each video clip and behind the scenes clip has its own Pgc entry. So each menu button points to its corresponding Pgc video clip. After reintegrating the edited movie it is now all in 1 Pgc. So the menu can no longer point to an individual Pgc to select a video. I guess I'm going to have to try and learn how to modify the menu, so that it will address each video clip by it's starting location. Thanks for the suggestions.
