First off I hope I am posting in the correct forum, as my question kind of touches a couple of boundries. It has been a while since I have been in the scene, and the new tools are amazing. I could not believe the automation progress that has been achived in the short amount of time I have been away. So I come from the days of doing things manually.

Becuse the tools are new to me I am following the Scenarist NT Full DVD Backup using DoitFast4U and DoCCE4U. Inside the guide there is a link to a mini-guide that explains when a break-out of vob-id is and is not necessary. This all makes sense to me, as I used to exclusivly do vob-id (lots of work, yes, consistent results, yes). My current project is exactly the same as example 3 in the mini-guide about vob-id. Where I have multiple PGC's that either contain unique vob-id's, or a cell or two from a vob contained in the main movie. For this scenario the author suggests creating chapter points at each cell. This makes sense, then the repeted cells can be obtained from the main movie asset and reused in the additional PGC's. At the same time you can simply fix up the main film by deleting the unneeded chapter points and adding the needed cells in there place.

Question, how do you go about getting correct chapter points for the individual cells to import into Scenarist? Hopefully the author is not suggesting that you manually create a chapter for each cell?

Question, What does DoItFast4U pass to DoCCE4U for chapter information for the encoding process? It would make sense to me that it scans the ifo and sends the chapter points as they are there?


Thanks

After working last night with this delema, I am a little bit confused. Take the following as an example (information removed for clarity).


PGC_1 (program chain): [00:13:01.27 / 30 fps]: (Cells: 8)
[Cell 01] [V/C Id: 1/ 1]: time: 00:04:39.26 [Pos: 00:04:39.26]
[Cell 02] [V/C Id: 1/ 2]: time: 00:02:40.26 [Pos: 00:07:20.22]
[Cell 03] [V/C Id: 1/ 3]: time: 00:00:14.09 [Pos: 00:07:35.01]
[Cell 04] [V/C Id: 1/ 4]: time: 00:02:45.06 [Pos: 00:10:20.07]
[Cell 05] [V/C Id: 1/ 5]: time: 00:00:06.05 [Pos: 00:10:26.12]
[Cell 06] [V/C Id: 1/ 6]: time: 00:00:37.29 [Pos: 00:11:04.11]
[Cell 07] [V/C Id: 1/ 7]: time: 00:01:25.16 [Pos: 00:12:29.27]
[Cell 08] [V/C Id: 1/ 8]: time: 00:00:10.15 [Pos: 00:12:40.12]

Now where I get into trouble is when I am looking at cell 1. Cell 1 has a length of 00:04:39.26, fair enough I can understand that. But the scene position is at 00:04:39.26. Scenarist automatically places the first scene at 00:00:00.00. So if I am creating chapter points to exactly resemble the above, I would place a scene boundry at each of the Pos locations. But if I do this, I do not get 8 cells, I get 9 cells. Because a cell is the material inbetween chapter points, cell 1 constitutes the time from 00:00:00.00 to 00:04:39.26. And then at the end of the block cell 8 would constitute the time from 00:12:29.27 to 00:12:40:12 for a difference of 00:00:10.15 as cell 8 is defined. But what about the material after Pos 00:12:40.12?? The end of the clip does not occur until 00:13:01.27, meaning that according to this information the time from 00:12:40.12 to 00:13:01.27 is unaccounted for in the cell structure????

And I see this exact result when adding chapters points into Scenarist for my project. Resulting in 9 scenes in this case instead of 8. Because Scenarist creats the 00:00:00.00 chapter point, there is a total of 9 not 8.

In my previous method I would use InfoUpdate to create the chapter points by cell for use when authoring by Vob-id. Would this still be valid for following this guide?

Hopefully someone can point out my oversite in the above so that I can better understand, and perhaps help someone else as well.

Thanks

Have you actually compiled? Scenarist doesn't usually make a 00:00:00:00 cell after compiling.

As for how I get vobid cell points, I use ifoupdates chapter output feature and paste these values into scenchap.

Thanks Eyes`Only for the info. I am still not sure how all the works out from an understanding standpoint, but it becomes irrelivent with the InfoUpdate chapter solution.

Still, one of the original questions is still relivent to me. I have read through the documentation and tried to find this information, but have come up empty.

Once DoItFast4U has completed its tasks it passes the necessary info to DoCCE4U. My question is, in setting up CCE manually in the past it was important to set the chapter points in the ecl file to make sure that there were I-nodes in the proper chapter locations.

Are there any chapter points set by the process for CCE??

If so how are they determined?

Would it be necessary in the above example to stop the process and edit the files to ensure that proper chapter points could be set by cell or is this a given as a cell is the smallest addressable space?

Again thanks for the help.
