Hi,

does neone knows the program ?
Looking at the generated output (example):

Would it be possible to determine the length of the cells within the VobIDs from this printout ?

The real length is as follows:
V/C 1/1 315 frames
V/C 2/1 252 frames
V/C 2/2 53 frames
V/C 3/1 1 frame (still)

I still struggling with DVD2AVI (1.76) giving wrong frame count in the .d2v project file.
It always forgets 1-5 frames at the end. This is very disturbing while recreating MultiPGC
titles (I know, I could use IfoUpdate, BUT it really bothers me). I am looking for a reliable
easy way to compare and find out how many frames DVD2AVI had forgotten while creating
the project file. The manual way is via VirtualDUB (the special version which opens VOB
directly) it's the only decoder I found so far giving the right amount of frames back.
Even DVDSource (AviSynth plug-in) is wrong (I guess it's build using DVD2AVI decoder).

Pls. gimme a hint ...

Well I can see a discrepency here. Original stream is NTSC but resulting one is PAL.

compression : MPEG-1
TV system : NTSC 525/60 Hz
Aspect ratio: 4:3
.....
chain time: 00:00:37:50
25 non-dropframes/s
foo2: 0 0
foo3: 0 0

Other than that given the frame rate and the reported length we have ...

chain time: 00:00:37:50
chain time: 00:00:12:45
chain time: 00:00:00:53
frames r 37:50 = 37.5sec = 0:00:37.12and ½ a frame = 937.5frames
No 2: 581.25 frames
No 3: 1 frame and 0,325 of a frame.

Actually as frames in Pal r 40ms in length there is a problem with the reported times cause noone is whole frame accurate.
1st has half a frame, 2nd a quarter and 3d half and something to it.

Very strange indeed.

Hi,

yes, IfoParser does it wrong. It calculates wrong times even if you import original IFOs. It never calculates same cell lengths compared to IfoEdit or IfoUpdate. Don't rely on it.

In the meantime I got what I need, thanks Jdobbs ! The new IfoUpdate can export chapterlists per VobID, where the chapterpoints represent the cell startpoints. This is ideal for re-creating a certain vobstructure e.g. with Scenarist. Re-build the VobIDs by Tracks and set the Scenes in the track using the chapterexport from IfoUdate.
Since it exports a CCESP chapter list as well (per VobID) you'll be able to re-encode the VobIDs individually.
Setting chapters in the VobID-encode-job forces CCESP to closed the GOPs at the chapter(cell)startpoints so that you'll be able to align the scene startpoints later on exactly.
The only drawback in the moment is, that DVD2AVI does not framecount correctly. It always forgets s few (1-5) frames at the end. This needs to be corrected (manual). Strange, the special VirtualDub version (with direct Vob import) counts right. I spoke to NIC he may fix that with a new version of MPEGSource.

Taken all that into account you can re-create VobIDs 100% correctly, at least for PAL ;-)
