Scenarist - Cells, scenes & chapters

[mikeathome]

Hi,

just a dumb question:

Re-doing Matrix VTS_2 (the main), has 18 PGCs in 18 Titles, so a PGC/Title.
Made of 40 Tracks (VobIDs) containing 116 Scenes (Cells). But has 38 regular Chapters. I am stuck...

I can clearly see how the are set-up looking in IfoEdit (or ChapterXtractor), means, which of the scenes are chapterpoints.
It's really a dumb question, how does my final project knows that 38 out of 116 have to be handled as chapter entries ???

I appologize, but I couldn't find anything while reading thru all kinds of manuals. Gimme a hint please...

Right-click in the scenario window and choose "Rearrange Chapters" and you can choose what parts of the layout you do, or do not, want as chapters.

THX, great info.

Do you know as well what are the Cell Types ???
In Matrix e.g. you have 8,10,12,14... (you see them as well in the ChapterXtractor (or IfoEdit in the VTSITITable)).

You should inspect the original IFO before starting the project to see how you need to rip it. A lot of times, ripping by PGC (the default in DoItFast4U!) is good enough. However, there are times that video segments are used again in other PGC's. If this is the case, you would end up with too much space used because you're duplicating needlessly. In these cases, you would have to extract by vobid and recreate the structure with those assets. Only in the worst of cases should you have to rip by cell id and recreate that way.

Yes, I know. I've done quite some conversion till now. Have you looked at Matrix ? You should try it (if you don't want to test it, then wait for Matrix II ;-). DIF4U isn't a good choice for Matrix, try it and you'll understand, i've posted my findings in the DIF4U post as well.

Matrix (R2 PAL), you do by VobID. You have 37 titles with 1 (one) PGC each (this is the same approach for all three video title sets).
In VTS 2 (the main movie) you have 40 VobIDs (tracks in Scen) build from 116 cells (scenes in Scen), reduced to 38 chapters in the navigation.
There are doubled cells (9 x 2 doublets, each one per rabbit pop-up, no:5,9,13,20...34,38), but they are definately needed because they have and have not the 2A (white rabbit) subpicture stream and they are NO chapters !!!
In scenario build ensure you follow the VobID sequence, otherwise you mess it up directly, means, put the tracks in the right sequence into the PGCs to re-map the original VobID structure. So, first all the VobID 1 occurance in all PGCs than all VobID 2, then 3, then... last VobID 40. DO NOT FILL PGC1 than PGC2 and so on (every add track creates directly a VobID -> so you mess up the VobID structure).
If you re-arrange chapters after scenario build up you end up with the right chapters till you IfoUpdate. IfoUpdate somehow messes them up again and later in the chapter-playback mode you jump to the wrong chapter when you select it in the chapter menu.
I guess this has something to do with the celltype flag !!! I wonder if it would require an IfoEdit patch of the created (new authored) titleset first. You change the celltypes in the PGCs (in the VTS_PGCITI table in the VTS_PGC entries, there are all cells per PGCs listet and the celltype can be changed). I did not find a way to influence celltype within Scenarist. As far as I investigated he sets all everytime to 8. Looking in the original IFO with IfoEdit you'll find all kinds of different celltypes within a PGC. They somehow reflect the kind of the cell (multiangle, seamless, chapter, cell start NO chapter (like the dummy chapter in Maestro where you can set an angle entry) and so on and so on...

My wild guess is, if IfoUpdate looks for celltype 8 in the new created IFO it will find to many 8s (because all 116 cells are flaged 8), so basically sets the wrong chapters in case it simply follows the cells. Some cells are NOT chapters and therefore flaged differently in the original IFO. I need more investigation on this...

Where are the real Ifo number cruncher, isen't there nobody outthere to light me up ?
