Extract single episode subs from dvd series

[Mildragon]

I have a DVD source which includes 4 episodes from a TV-series and I converted them with megui to .mkv

I used .avs cutter and audio cutter tools e.t.c.

All nice and clean except for the subtitles. They are extracted in a single .idx/.sub file with full duration 1h 40min.

O.k. no problem for the first DVD episode, but what about the other 3 episodes? The problem is that all 4 episodes are in the same .vob file. I mean is there a way to extract the .idx/.sub files for e.g. only the third episode? (with time starting from 00:01:00-->25:02:06, this is the duration of the third episode, after converted to .mkv)

Thanks in advance.

You can use VSRip. Make sure you choose the PGC of the episode you want.
OR you might wanna check SubExtractor (http://subextractor.codeplex.com/) instead (supposed to be really good)

(Batch) rip single eps with DVDfab in movie only mode and encode these with MeGUI. Why waste time with cutter tools?

You can get the subs for each episode after the first by using the little SubCutter utility that comes included in the VobSub package:

You'll have to know the total length of the episodes that went before the one for which you want the subs so it can get the timings right.

Easier said than done if all the episodes are in the same title (PGC), as is often the case.

DVDfab doesn't care and extracts them separately anyway.

Maybe, but not without some help from the person at the keyboard, and it's nothing DVD Decrypter can't do. For some reason DVDFab wouldn't let me take a pic of the main screen, so I capped the screen where you can choose the chapters to decrypt. What follows are screens from DVDFab and from DVD Decrypter of a four-episode anime all in a single PGC. Yes, you can choose five chapters at a time to decrypt. Is this what you meant? Since Mildragon already has his encode all split up, easier, I think, would be to split the subs. Maybe for future reference he'll remember how to split by episodes.

What if Mildragon didn't split the single vob file into episodes using MeGUI by cutting the vob file in the same places as it'd be "cut" when ripping the DVD as individual episodes or using DVD Decrypter? If that's likely to cause a problem it might be easier to start again, rip the DVD as individual episodes and encode each one separately. Or use DVD Shrink to re-author the DVD he's already ripped. It's only one DVD so not the end of the world to do it a second time and do it "properly".

DVDFab will no doubt rip a DVD as individual episodes and is probably the easiest way to do it. Personally I still rip most DVDs the old fashion way and then use DVD Shrink to resave it as individual vob files for each episode. I can't remember the last time I came across an episodic DVD where each episode wasn't a separate title so it's not hard to split one into epsiodes using DVD Shrink, but even if the whole DVD happens to be a single title it's still not hard to use DVD Shrink's re-author mode to split it into individual titles/episodes.

For me it's also a long time ago when I last saw individual eps put into one file which is just stupid authoring. Apart from the fact that Decrypter can't beat recent copy protections judging from the right screenshot I don't see how it's better suited for this task either.

In this case I'd use DVD Shrink's reauthor mode too.

[Mildragon]

Well, I don't have the DVD disc in my possesion, I just have a VIDEO_TS folder in my hard disk. I don't know how Dvddecrypter would handle this issue but Dvdfab didn't do the trick, because the end credits of an episode could not be matched exactly using Time start/end settings. The program would either include the end credits on the episode I wanted to reauthor together with the first 3 min of the next episode or cut them in the middle, so as to be included (the other half of the end credits) in the next chapter-episode. So, I guess I'll have to stick with the subcutter tool that Manono suggested.

So do you still have the DVD saved to your hard drive as a single set of vob files with a duration of 1 hour 40 minutes as per your original post?

If so, open the files with DVD Shrink and use it's re-author function. Usually it involves nothing more than dragging the title corresponding to each episode from the right pane to the left pane and then using the backup function to resave just the episodes as a new DVD compilation on your hard drive.
If all episodes do happen to be one title you can drag the single title to the left pane multiple times (once for each episode) and use the edit function to trim each one down to a single episode. Then re-save it as a new DVD compilation using the backup function.

That'll give you a set of vob files per episode to work with. It'll probably be easier to start again and re-encode them individually too.

I did as you and Chetwood said but will I have any loss in video quality even by using the no-compression mode? If not, then I'll stick to this method.

No, no loss of quality by doing it that way. It may be a little bit tricky cutting at the exact place between the episodes. Better, I think, if this thing really is all episodes in a single title, would be to divide it up by chapters using either DVDFab HD Decrypter or DVD Decrypter. I couldn't quite understand if that's what you tried with DVDFab. I've never used DVDFab for that, but DVD Decrypter has always done it perfectly for me. And I have yet to find an episodic DVD that had advanced copy protection, although I suppose there could be some.

[Chetwood]

There will be no loss in quality if you set output to DVD-9 (when you put all eps on one DVD) or the ratio is 100%. BTW, DVDFab also allows to split by chapters, dunno if it works in batch mode though.

Yeah sorry, I forgot to mention that. As Chetwood said as long as you set the destination DVD file size to something large in DVD Shrink's options it'll just resave the video when backing up and won't attempt to shrink it.
