IFOUpdate : "Not correctly sized on sector boundary" error

[RB]

Sorry to bother you again jdobbs, but I have another small request for the next version.

Sometimes there are PGCs that have chapters consisting of multiple cells and you want to recreate this layout exactly (like in Pirates of the Caribbean), but IFOUpdate records this only in the CCE chapter files, not the Scenarist/Maestro chapter files. So it would be nice if in addition to the PGC0x-SCENARIST.CHP files, you could create PGC0x-SCENARIST_ALLCELLS.CHP files that would list a chapter point for every cell (remember, except for cells that belong to Angle 2 and up).

And another small bug report: once "Auto-Set Region-Free" has been enabled, it never can be unchecked ;), remains checked across program runs.

Thanks!

Another small request :) (jdobbs, hope I'm not getting a pest).

Could you add an option to not transfer the number of cell commands when updating? I just had the case that the original cell had a cell command but I didn't recreate it in the authored one. Now after updating, the cell command was still there in VTS_PGCITI, but the cell command Nr had been set to zero....

[jdobbs]

No... I just haven't had a lot of free time to work on it...

[RB]

Take your time :)

Also, there's a problem with Adjusted Cell Mode and multiple angles (this happened in v0.72 too). If you keep angles and save Chapter Files in Adjusted Cell Mode (didn't check the other modes), you get incorrect chapter files because IFOUpdate counts each angle as a separate chapter/cell (chapters are "off" by the lenght of additional angles after the first angle point(s)). To get correct chapter files, you have to check "Ignore Angle cells" before saving chapter files and uncheck that option before updating IFOs. Maybe this can be corrected in one of the next versions.

I've just one question about this. What if people re-author the whole m2v?
Let me try to explain in my bad english.

On titles with Angles and/or Duplicate VobIDs I just demux the whole m2v, ac3, etc with VobEdit, encode with the CCE and Chapter/cell points, and re-author with maestro and Chaps created by IfoUpdate. Then I just run IfoUpdate in adjust cell mode and the resulting DVD plays fine. So if you take out the information about the angle cell you cannot author the full m2v but have to cut it by vodID.

Did I make any sense??

[RB]

As I said earlier in this thread, you really can't "encode/reauthor the full M2V" if there are multiple angles. You have to break it out by VobId, work around the bug in IFOUpdate as outlined above if you want to use Adjusted Cell Mode, and place the reencoded VobIds on the timeline as you quoted. If you just reencode the entire M2V you'll get a too long M2V that is constantly "alternating" between the different angle video streams in the multiangle parts.

As I said earlier in this thread, you really can't "encode/reauthor the full M2V" if there are multiple angles
Why not? Theoretically an angle is just a normal cell in the Vob file. By encoding/reauthoring the full m2v we are just creating a copy(kind of) of the original vob structure (although smaller) just like the graphical display in IfoUpdate shows. So running IfoUpdate "adjusted cell mode" will map that cell to the correct place, which is an angle.
I have to admit that I dont remember if I tested the "full M2V" method in movies with cells, although with duplicate VobIDs it works great, so I'm gonna test this scenario in a movie with angles and post my results later.

[RB]

Trust me, it won't work, tried it :). The problem with angles is that the video of the different angles is interleaved within the angle cell(s). Just make an AVS for a multiangle "full M2V" and play it in MediaPlayer, got to an angle section and you'll see what I mean. And even if you don't touch the M2V and try to reauthor that, you'll have a M2V that has the length of main movie plus all angle parts, so it's too long and the audio won't match. Authoring programs just have no way to "recognize" that what you're importing is supposed to be multiangle. No way around that.

[jdobbs]

As RB points out, in the original stream the angles are interleaved -- and if you look at it with VOBEdit you'll see that the VOBIDs and CELLIDs alternate also -- the package that builds it back for you would have to know that and also where it happens. Also the Frame count has to match exactly between the two angles and each of the interleaved points.

Another problem is single-frame points that might be in the file -- in the original they are all I frames and are set to play some set period of time.

It's not impossible to do, but it is probably more trouble than it's worth.

[BaRRoS]

Yap, silly me :rolleyes:
I completely forget about the audio/video durations. Since we have more than 1 scene (angle) we would also need more than one audio track.

Another problem is single-frame points that might be in the file -- in the original they are all I frames and are set to play some set period of time.

I'm currently having problems with this. I'm trying to backup Lion King SE R2 PAL Disk2 (which is a big authoring mess: empty PGPs, duplicated VobIDs, Angles, still frames, menus in VTS_*_1.VOB, to name a few) and I haven't yet found a simple way to deal with still frames. Any thoughts??

[RB]

I think you need Scenarist for this. As for the still frames, use a Slide Show track in Scenarist. Import a bitmap file, then drag it into Track Editor, select "Slide Show" from the dialog that pops up. Set the duration of the bitmap to the same as in the original.

avoiding starting a new thread for a simple request.. i thought id add it to a ifoupdate thread

i was wondering if it were possible to add an option in the save chapter file menu for a 'scenarist cell file' that would do the same as the 'scenarist chapter file' option (ie chapters based on pgc with separate pgc files) but having the cell times. would come in handy during a manual reauthor at the end of the big 3 when i dont use ra/scenaid. right now i use RB's chapter importer with the chapter file but then go back and add the non-chapter cell times in.

thank you

[RB]

Just import the CCE chapter files (which have all the cell positions) with SceneImport.
