PgcEdit v8.6 released (January 12, 2008)

[r0lZ]

I have never seen that, but someone else has also reported that problem.

Is it a tiny cell (dummy chapter) at the end of the PGC? I'm not sure, but it might be the cause.

Can you post the log of the verify operation?

I pasted the second one in because I don't know how to tell if there is a tiny cell at the end of the PGC.

p.s. why doesn't the first log carry the DVD name while the second does?

[r0lZ]

To verify if there is a tiny cell, double-click on the PGC and look at the duration of the last cell in the cell table. If it is less than one second, it's a tiny cell. You can also preview the cell (with the button of the last column in the cell table.) It should be all black.

But since the PGC duration difference is more than one second, I guess the tiny cell (if present) is not the problem.
Unfortunately, as I said, it is not easy to find the problem, as I have never encountered this problem, and therefore, I have nothing to test.
Can you verify yet another thing? When you rebuild the time map with PgcEdit, the total duration of the PGC might be modified in some cases. For example, it could be modified from 2:15:26 to 2:15:32 (for the first PGC.) Is it what you got?
And with VobBlanker?

That's a little omission. Will fix it...

[Dr.Khron]

Two things I've noticed with new version:

1. minor quibble:
GUI size is off. Since I have an enormous monitor, I run large fonts. At first, the PgcEdit GUI comes up with windows that are too small to see all the buttons. However, since the program is very good about remembering window sizes, I only have to adjust them once.

2. potential bug:
On my homemade DVD, I imported several VTS to make a compilation DVD. Opening any of the Title PGCs with the PGC Editor window produces a pop-up that asks:

WARNING: the PGC Playback Time (00:48:13.16 (at 30 fps)) doesn't match the total of the cells times (00:48:13.15 (at 30 fps)).

Fix it?

If I click No, it will ask me this EVERY time I open the PGC Editor for that PGC.

If I click Yes, it will fix the problem.

When I was finished with my editing, I used the "Rebuild all time maps of DVD" option, becuase I had added tiny cells to the end of the Title PGCs.
(see thread: 'Next Chapter' button jumps to next title )

While rebuilding, it finds problems with every Title, here is an example::

Some times have been fixed in VTS_TMAPTI of VTS 2:

VTS 2, PGC 1 playback time: 00:48:13.15 -> 00:48:13.16

However, now if I open any Title PGC in the PGC Editor again, it tells me that the Playback times don't match. If I fix it, rebuild time maps will find it as an error, and so on in an infinite loop.

Which state is correct, after rebuilding time maps, or after fixing the playback time?
Each one thinks the other is wrong.

[r0lZ]

1. I haven't changed the window sizes in v8, except that the PGC Editor remembers now its size and position. However, the first time you open it, it should have the same position and size than the fixed dimensions of the previous version.

2. It's probably related to the problem just reported by linx05 here. I don't understand yet what happens, but I'll try to fix it. (BTW, here again, I haven't changed anything regarding the time maps in v8.)

[frank]

Just use FixVTS and look.

[linx05]

Here are the logs for PgcEdit and Vobblanker. 'before.txt' is the time map log before I did anything to the ripped DVD. 'after pgcedit.txt' is when I tried fixing the time map in PgcEdit. 'after vobblanker.txt' is the log for when I processed the DVD through VobBlanker. And finally the vobblanker log is from VobBlanker.

Download them from here.

In regards to the tiny cell request, I checked each PGC which had the time map problem and each had a tiny cell (00:00:00:15) at the end. Though other PGCs also have this tiny cell (same length) but the time map is correct on those. I hope this helps.

[kumi]

I get that same discrepancy with the Verify Time Maps plugin very often

I reported it here: http://forum.doom9.org/showthread.ph...749#post893749

[r0lZ]

Sorry, but I have tried again to reproduce the problem, without success. I've also re-read my code, and everything seems correct.

BTW, when rebuilding the time maps, have you ever got a log with something like that?:

Some times have been fixed in VTS_TMAPTI of VTS 1:

VTS 1, PGC 1, cell 11: 00:05:40.12 -> 00:05:43.12
VTS 1, PGC 1 playback time: 01:13:56.22 -> 01:13:59.22

Also, is it an ARccOS/RipGaurd protected DVD? In this case, how did you rip it?

If, per change, you can find a small PGC with the problem, could you upload the IFOs and the title VOB somewhere? Thanks.

[linx05]

I've never seen a log with that in it. The disc has only got CSS encryption on it. I used AnyDVD. I just did a re-rip with RipIt4Me and the error still happens.

Could you tell me how to extract a PGC and the title VOB please? I've been looking for a way but no luck. Thanks.

[President]

2linx05
I constantly gets such error messages about timemap duration on NTSC DVDs (after rebuilding in PGCEdit). On PAL DVDs a timemap rebuilding is always correct (if a VOB files are not corrupted). Probably it is a normal .

[r0lZ]

Ah, NTSC! I didn't though at that. I made all my tests on PAL material. Will try with a NTSC DVD tomorrow...
Why such a crappy standard exists? I've already lost so much time on problems caused by the complexity of NTSC!

[Dr.Khron]

Whats next, you gonna bad-mouth 110 volt AC power?

Seriously though, a trip through Vob Blanker fixed the never-ending loop of fixing time maps discprepancies. And yes, it was NTSC material, but ironically, it started out as PAL material that I converted to NTSC.

[linx05]

Woops sorry . I just figured there would be a reference to NTSC in one of the logs. You might like to add that to them at the top, a little bit more information for you.

If you still want I can extract a PGC/Title VOB but someone has to tell me how. I really appreciate the trouble you're going to help find this problem.

[mpucoder]

NTSC is not a problem to those of us who grew up with it, and for DVD purposes it's just another resolution/framerate. Pulldown most likely is what is causing the discrepency, and is allowed in either standard (see DGPulldown for converting 24fps to 25fps). After pulldown there should be an even number of fields, for many reasons (and to meet DVD spec). An odd number can result in one function rounding up the number of frames, while another truncates (rounds down) resulting in a 1 frame difference.
It is permissable to have an odd number of fields in a cell (so long as the vob has an even number), in which case the cell elapsed time should be rounded up for the first occurance, then down (to account for the borrowed field) for the next occurance, and so on.

[r0lZ]

Thanks to everybody!
I have two NTSC DVDs in my collection, and I'll try my functions on them. If I can't reproduce the problem, then yes, I'll need a small VOB.

Linx05, if you want to extract a cell, you can do it this way:
- Remove all unnecessary titlesets and menu domains with PgcEdit, to keep only the VOBs with the cell to extract. You might need to use Remap Titlesets before using Delete Last VTS.
- In the remaining VTS, remove also the unnecessary PGCs (with Remap PGCs, Reorder TTNs and Delete Last PGC.)
- In the remaining PGC, remove all cells (with Remove Cells in the PGC Editor)
- Process the domain through FixVTS to remove the unnecessary cells from the VOBs.
- Try to apply the Verify time map function to be sure that the cell exhibits the problem, but, according to mpucoder, a single cell should not cause the problem, as the rounding error will be less than one second.
(Note that you can also remove easily the useless VTSs and PGCs by deleting all commands in the DVD, and recreating only a single JumpTT in the FP-PGC, to the PGC you want to keep, and then apply the automatic function to remove the uncalled PGCs.)

[r0lZ]

OK, I've managed to reproduce the problem. It happens only on the main title, so I guess mpucoder is right. There are probably rounding errors accumulated on too many cells.
I don't need the VOBs.

[linx05]

Yes! Thank you r0lZ! I was half way through doing the VOB thing too.

[r0lZ]

OK, I think I got it! I'll release a new beta soon, but before, I want to add a workaround for a SCR discontinuity problem when there are several VOBs merged by VobBlanker in one big cell, reported here.

[r0lZ]

PgcEdit_winexe_8.1beta2.zip

Could you test the Rebuild Time Map functions of this beta, especially with NTSC material? Thanks.

I have also added a simple check to ensure that the VOBU End Presentation Time is always greater than the last one (in the same cell, of course.) This is to avoid a bug in VobBlanker when the user replaces a single cell by several cells pertaining to several VOBs (with different VOB IDs.) In this case, VobBlanker joins all cells as a single cell, but it doesn't fix the SCR and VOBU End Presentation Time values, and therefore, the VOBU End Presentation Time jumps abruptly to a low value in the middle of the new cell. I've contacted jsoto, and he will try to fix this problem. In the meantime, it is recommended to abort the rebuild time map operation when this warning is displayed.

BTW, currently, the test is very basic, but I can probably improve it a bit. I need to know the minimum and maximum duration of a single VOBU allowed by the standard. Someone can help?
