Scenarist 3.1 and Audio Availability Flag

[mp3dom]

Hi to all!
I have this kind of problem:
I have a track with 4 audio stream (1: French 5.1 448 Kbps, 2: French 2.0 224 Kbps, 3: English 2.0 224 Kbps and English 2.0 128 Kbps).
The latest audio stream is a Director's Comment track. Now the problem is that I want to have 2 Titles in the same VTS, 1 Title with 1 PGC with 3 tracks and the second title with only the Directors Comment, so during the movie it's not possible to switch to the director's comment and viceversa during the comment it's not possible to switch to movie tracks. This is possible in DVDMaestro but seems impossible in Scenarist. The Audio Availability Flag is set to Custom, I've enabled the 3 checkboxes in PGC1 choosing decoding stream from 0 to 2 and enabled only the first checkbox in PGC2 decoding stream 3, but when I compile the project Scenarist says that the coding mode or language mode in PGC1 and PGC2 are different each other. Is there a workaround? I think that it's possible to change decoding stream order or excluding some tracks in PGCs but Scenarist seems to not fully support it...
Thanks!

Your problem is that stream#0 in PGC1 is different to stream#0 in PGC2. You will need to create some dummy audio (use the 4 audio files you have and with besweet? cut the first frame.

Now add the cut frame of english 128kbps as audio stream 4 in the the track you are using for PGC1 (and set language to english).

Now add the other 3 cut audio files for stream 1,2,3 of the track being used for PGC2 (and set languages to french,french,english), and then add english 128kbps as stream 4 in this track (and set this to english).

You now have 2 tracks (1 for pgc1, 1 for pgc2) that have identical audio attributes for each stream

Thanks for the answer Zeul!
Correct me if I'm wrong:
So I need to create 2 different tracks (in Track Editor) from the same data (in data editor) so I drag the video in the track editor twice to create 2 different tracks. Then I drag real audio (stream 0,1,2) and 4th dummy to track 1, then dummy 0,1,2 and real 4 to track 2? But with this method do I "double" the space required in the DVD? Also, the dummy tracks are 1 seconds long (for example) so next there is no audio. This affects the total bitrate? I mean... do I need to subtract the dummy track bitrate (the 4th track for example) from the 9800 Kbps max limit even if the audio is not really available? Thanks again!

Ok i totally misread your first post.
I now see what you are trying to do - 1 track with 4 audio streams. 2 titles, title1 with 3 audio, title2 with 1 audio.

Herin lies your problem, scenarist won't allow this because you are disabling audio streams 1,2,3 in Title2.
So either, use a different authoring app that does allow it, or compile with all 4 streams flagged in Title2 and then post process the PGC in the IFO (with pgcedit,ifoedit) and set audio streams 1,2,3 to == 0, only stream 4 will have a value and change this value to 32768 so it becomes the default.

Ok, Thanks!!! I'll try!!
But is this "operation" DVD compliant? Is it an unsupported feature in Scenarist?

[Zeul]

I allow this in DVDPlanner and the verifiers have never complained. I would think it is one of those 'grey' areas. In actuality this is seen quite a lot on commercial DVDs, so i believe it is an error with Scenarist.

I am misinforming you for the post processing. :stupid:

What you should do is before compile change Title2to 'custom' and select Audio stream1 only. Make this the French 5.1 (the same as Title1). Scenarist will now compile.

Now in post processing, you want to change PGC2 audio attributes for Track 1 to 33792. This will now make Audio Track 1 of PGC2 play Audio stream4 in the VOB file.

So, recapping:
In track editor I make the track with 4 audio stream. In the Scenario Editor I make 2 PGC. Both with custom Audio Availability Flag. In PGC1 I select stream 0,1,2 (leaving stream 4 off), in PGC2 I select stream 0 and associate to the first track (French 5.1). After compiling I open the IFO, select the PGC2 and change the audio attribute for stream 0 to 33792 (track 4).
Am I correct?
Thanks again!

correct

Ok, Thank you very much!!
