View Full Version : Easy approach to strip subtitles from VOB ?

Hi all,

as we are required not to ask "whatīs best" Iīll try to reformulate my questions to this:
"What is an easy to implement"-approach to strip subtitles from VOB files ?

Reason for asking: Most "One Click-DVD Backup" solutions seem to have issues with keeping the subtitle attributes. Sometimes DVDs have subtitle tracks that are both: Normal subtitles as well as forced subs. The original DVD plays back fine whereas the produced backup has often problems. Mostly the "marking" of the subtitles as forced sub goes away. This really sucks for movies with a lot of foreign language dialogues (example: Last samurai). So you can only watch the backup with subs turned on.

The manual way I deal with this:
· Stripping subtitle streams manual with VobSub and selecting the subtitle matching my mother tongue.
· Setting the flag in the Vobsub config file to display only forced subtitles to "Yes"
· Loading the subtitle streams via AVISynth and the related VobSub plugin
· Encode
This is fine but sometimes very time consuming. Would there be a way to run VobSub via CLI stripping all subtitle streams remaining in the VOB files ?
Or even better: Could I just "demux" the subtitle streams and remux them with mplex ?

Research in the internet and the forum unfortunately didnīt answer my questions. May be someone can help.

TIA,
D$

I don't understand what the problem is.

If the problem is just an attribute on a subtittle to force it, then IFOEdit would probably do the trick. Or write a small tool that fixes up the bit in question. That shouldn't be difficult by any means be particularly difficult.

If you need to strip (as in remove) subtittles from an existing DVD I do believe most DVD-copy tools will do so when they are running in 100% quality / 100% of original size mode.

@Enots_:
Agree, may be I need to clarify what I mean by "stripping":
I was refering to the "demuxing" or "extracting" of the subtitle stream(s) as stripping. Not to mix this up with the "stripping" that might be done when you remove unwanted subtitle streams. This can of course be done very easy by using DVDShrink instead of ripping the full DVD.

Iīm not really shure what causes the problem that the "Forced Sub"-Marker goes away but I had this problem with a variety of OneClick-DVD Tools (DVD2DVD-R, DVDRebuilder, DVD2SVCD) and various DVDs. Last Samurai was one of them.

Only the manual way I described worked. So again my question:
What tool which I can run via CLI is able to either produce VOBSub compliant streams which I can "hardcode" into the movie or spits out the subtitle streams in a manner I can mux them with my encoded video ?

Thanx,
D$
