Polar Express questions

[hoops10]

Trying to back this one up, too :) I noticed in DIF that in VTS 1, there are 3 pgcs that are all the same length, but are not dupes (as DIF would have unchecked them.) I did some more research and found that they are full versions of the movie just in English, Spanish and French. Can I just uncheck PGC's 2 and 3 (praying that PGC 1 is the English version)?

I have attached a txt file showing the IFO of the main movie to help clarify my question.

[Zeul]

The english audio stream is id 0x80. Open up the PGCs and whichever one has the audio attributes using stream 0 (will show as 32768) is the correct PGC to keep.

Funy structure. I bet those movies have different begin credits as they have some different vobids at the beginning of the pgcs? They could have solved that with different angles but that would have suffered bitrate I guess. You could do a void demux and keep all the pgcs if you want. They are mainly duplicates anyway (except for the short vobids at the beginning). So you could keep the structure intact (and replace the audio of the other pgcs in scenarist if you're not interested in the foreign languages)

[hoops10]

So if I do what Zuel says, and just keep the English PGC, will the structure of the dvd still be ok and playable? Or do I have to do as flu suggests and demux by vobid and manually put the vod ids back together in Scenarist?

[influenza]

If you go the vobid way scennaid will create a scenarist script for you and you don't have to do that manually. Only replacing the audio. Although I'm not sure how scenarist will mux that (if it actually takes 3 time the space of the audio or just once)

[hoops10]

flu: If I only wanted to keep the English track, I assume I would have to use it in the other PGCS that weren't normally English. Is that right? If so, how would I do that?

[D3s7]

you could do it by pgc and just deslect pgc2 and 3 as well.. scenaid will dummy those (or the missing cells)

[hoops10]

D3s7: Can I just do that? I thought I needed all the vob ids and if I deselect pgc2 and pgc3, then I won't have them all, right?

[jel]

the real question is whether you want all 3 versions or not.

as this contains ILVU, even if you demux by vobid, you will get some non-seamless connections between cells which may cause a slight pause when played on a dvd standalone player.

so you have to make a few choices ...
demux by vobid and keep all versions but may have non-seamless connections in your main movie
or
demux by pgc, as d3s7 suggested and let scenaid dummy the non-demuxed cells from pgc_2 and pgc_3
or ....
demux pgc as above AND demux the additional vobids from pgc_2 and pgc_3 and re-create pgc_2 and pgc_3 in scenarist manually <--- this is the method i use when i want to keep all versions in an ILVU title.

demux pgc as above AND demux the additional vobids from pgc_2 and pgc_3 and re-create pgc_2 and pgc_3 in scenarist manually <--- this is the method i use when i want to keep all versions in an ILVU title.

yeah that's a good solution

[hoops10]

jel: I want to follow your suggestion of "demux pgc as above AND demux the additional vobids from pgc_2 and pgc_3 and re-create pgc_2 and pgc_3 in scenarist manually <--- this is the method i use when i want to keep all versions in an ILVU title." But instead of keeping the French and Spanish tracks, I only wanted to keep the English track, would that be possible? If so, how would I do that in Scenarist?

[influenza]

I you only want to keep the english version I would only demux that pgc and dummy the others, that would be much faster in your case. The other suggestion requires scenarist knowledge and I think you slightly lack that (no offense meant).

But if you want to give it a go: demux by pgc (only pgc1) and encode. ALso demux by vobid (well only the vobids that are not in pgc1). Let scenaid create a script for you and import it into scenarist.
Also import the vobids seperately demuxed and encoded. create tracks for those vobids.

Now replace the dummy pgcs with both material from the demuxed pgc and the seperately demuxed vobids.

flu: I actually did do it the harder way. And I did it just as you said, on my own. I do know a little about Scenarist, not as much as most on this board. I kinda actually surprised myself when I was able to import the other vobids in and use Scenario Editor to make them work. I guess I know more than I thought. Thanks again for all the help.

[influenza]

hehe, well like I saiud no offense menat, but I was assuming you didn't have much scenarist experience based on your questions ;). Doing this 'the hard' way is an excellent way to learn about dvd authoring and dvd structure.

I'm glad you sorted it all out.

[jel]

good work hoops :D

personally i prefer this method over a standard vobid demux for all ILVU titles. i have spoken to Eyes`Only and D3s7 in the past about incorporating this into dif4u/scenaid, with the option of user selecting which pgc to process via pgc and which to process via vobid.
guess we will have to wait and see ... ;)

[hoops10]

I have just a curious question. If, in this movie, PGC 1,2, and 3 were all the same, just different languages, why didn't DIF see them as dupes and uncheck them?

[D3s7]

becuase it had different cells in it for the different languages

like the credits or certain ads

[influenza]

yeah, those pgcs aren't duplicates. They contain different vobids and different audio layout. I haven't exactly noticed the differences, but it's probably credits and in movie sequences in the selected language (newspaper and other written things)
