View Full Version : BD-RB Forced Subs

I have been reading a lot to try to figure out how forced subs work on a BD since I do not get forced subs automatically output from BD Rebuilder. My player of choice is SageTV v7, but even with VLC, no force subs (and not selectable track of forced subs only).

For example, District 9 or Xmen First Class. I get full english subtitles on/off, but ideally, listen in english, then when the prawns speak, english subs. It must be something I am just overlooking, since there are not tons of bugs filed on this sbuject in the BD-RD bug forum.

https://spreadsheets.google.com/pub?key=t8Xb85eyNFtZ3vaNK8gqkbQ&single=true&gid=0&output=html is tracking how and in what track are the forced subs on a per movie basis. Does BD Rebuilder flag "forced sub on" based upon the audio track you want to keep in set up?

Sorry for the rambling. Any help, direction, insight... would be greatly appreciated.

The only thing I can imagine is that you may have "Limit to One Track for Each Language" checked in SETUP. Often the subtitle track for forced subs (like District 9) is separate from the standard subtitles, and when you have that option selected in SETUP, the track with the forced subs is not included.

The "forced on" flag is embedded in the subtitle track (and within the .SUP file). If you keep it -- it will be forced on when you play it back. This is true whether you do full-backup, movie-only, or even ALTERNATE/DVD output. Resizing your output changes it slightly, but still should keep the "forcing".

Subs are pretty small and don't have much effect on quality when kept, so I always recommend keeping all subtitiles.

I'm moving this question to the DVD/BD Rebuilder since it applies to that software specifically.

I have found some titles recently actually have a separate subtitle entry for the forced subs and you have to both include them and default to it being on for the forced subtitles to appear. I generally identify this by playing the original title first to see if any subtitles are activated even though I choose "no subtitles" in play setup. I seem to recall that "XMen First Class" is one of those titles. BD-RB handles this fine when outputting a BD. But I have not been able to convince BD-RB to default to a subtitle being active when alternate outputting to DVD (maybe jdobbs has made a recent change in BD-RB to enable this capability?). I recall including both english subtitles, but still having to use pgcedit to insert a command in the resulting DVD structure to turn the required "forced" subtitle on when making a DVD of "XMen-First Class" from my blu-ray of that title.

I have built District 9 and XMen First Class with both only 1 English sub and all English subs.. neither will play back with the forced subs.

Per your recommendation, I will give "keep all subs" a try.

UPDATE: Ok, gave both a try. Still no forced subs when playing with VLC. When I select Subtitles Track > Track 1 (english) I get the full english and prawn subs. I've attached my logs to see if there something you can see. Thanks
