The pgs streams are
Based on review 8 has all normal events and timing for theatrical. Forced Events from 9 are included but not flagged forced. 21 is like 8 but with timing for directors.
9 forced with timing in sync with 8
22 forced with timing that is not relative to movie start but at start of mts it is contained (based on high level review of movie and lengths of mts segments.
To get a full theatrical rip would require:
or 8 and 9 merged
22 with a correction to all times
Anyone worked with Alpha? The Avatar BD I have exhibits the same authoring pattern.
Edit: method engineered to get desired results.
1) Ripped BD with MakeMKV to mkv file
2) MKVToolNix mkv file to set forced track flag in mkv file
2) TSMuxerGUI mkv file to iso file
3) BRR iso file to new iso file
While in BRR subtitle editor I merged forced track with main track. All works in terms of subtitle playing forced or descriptive text and forced. Not sure this should be a typical method or is optimal but since it’s all digital I expect results are fine. Causal 15 minute viewing looks and sounds ok. Gonna pull BD and try it on Avatar.
Subtitle_9_English_Forced = 218 Forced events.
Track 9 contains Type 2 events (218 events separate from main English subtitle track 8 that are flagged as Forced).
Subtitle_22_English_Forced = 213 Forced events.
Track 22 contains Type 2 events (213 events separate from main English subtitle track 21 that are flagged as Forced).
Merge difficulty = Medium (Four events in Track 8 and three events in Track 21 require manual search).
Detection = Automatic Mode supported.
Subtitle tracks 8, 9, 21, and 22 are present in both the Theatrical (Playlist 800) and Director's Cut (Playlist 801).
If creating the Theatrical version with English subtitles:
Load playlist 800, select subtitle tracks 8 and 9, use editor to merge all tracks, manually search the 4 not detected events.
If creating the Director's Cut version with English subtitles:
Load playlist 801, select subtitle tracks 21 and 22, use editor to merge all tracks, manually search the 3 not detected events.
This disc has nothing special about its subtitle events. It just contains both subtitle versions in both movie versions. It took no special steps or other programs to get the correct Normal and Forced subtitles merged into a single track.
