Scenarist and Different Audio Types

[jriker1]

I have a DVD I am trying to author with a bunch of main and sub menu elements and then four title elements containing four movies. Three of the movies have identical audio:

Bit Rate: 224000
Channel: 2 : 0
LFE On: No

The second of the four has:

Bit Rate: 448000
Channel 3:2
LFE On: Yes

I didn't have the heart to downgrade the audio to what the rest were. I'm guessing it's going to be a lot of work to try and create dummy PGC's and then link them back and forth between the VTS's and get all the menu's working like they would with a single VTS DVD. Questions:

1. Can I just edit the scenarist script file and spoof Scenarist into thinking the second audio file is the same as the rest?

2. Is there a nicely documented example of how to create this DVD the "right" way?

Thanks.

You can make it work by putting a dummy 5.1 track as 2nd track in the 2.0 videos and a 2.0 dumm yin the 5.1 video, put the 5.1 in a separate title, build dvd then hack the decoded stream #-s in the titles (set 0 for second in the 2.0s and stream#2 for stream id 1 and 0 for 2 in the 5.1 title). Unfortunately you can't do this hacking in Scenarist as it won't let you build the dvd if you have different stream decodings in titles.

Thanks for the reply DaRat.

OK, so I have all my dummy 5.1 and 2.0 ac3 files set. Tracks 1, 3, and 4 are 2.0 and 5.1 dummy in the second. Track 2 has 2.0 dummy first and 5.1 secondary.

For the hacking part, you mentioned, I read about a pre-command setting the correct audio track and then a post command setting the audio track back to it's original state. Not sure how to accomplish this, or if this would be the better route to take.

I have been thinking on this and how about the following:

1. Open Scenario Editor.
2. Go to Title_2 PPG
3. Edit Pre command
4. Set to: 1. SetSTN audio=2, angle=1
5. Close simulation window.
6. Edit Post command.
7. Set to: 1. SetSTN audio=1, angle=1
8. Close simulation window

Not sure if I have a sub though that I directly call from a menu if the pre/post commands run, but this seems sound. Any thoughts?

Thanks.

For the hacking part use a post-authoring program like Ifoedit or PGCEdit. PGCEdit is the easier one. Just load in the new DVD folder, open the title and alter the audio attribute.
