How can I rip DVD subtitles to SRT format (or something else that iPads can understand)? Title says it all. I've used HandBrake, Subler, VideoMonkey, and RipIt. I'm familiar with mencoder. None of them seem to be able to rip the subtitles from a DVD and then get the soft subtitles to the iPad.
This is by no means a complete answer but if the DVD you are ripping contains Closed Captioning subtitles then HandBrake gets you this for free.

Simply add the subtitles as a track. You'll be able to clearly see what must be burned in and what doesn't have to be by the options that have been greyed out.





I actually really like this option and use it whenever I can because different software can display these subtitles in different formats and all of the Apple playback software that I've used does a really nice job of displaying it readably and beautifully. I should also note that unchecking the Burned In check box won't make any difference on an iPad.

The problem is with bitmap subtitles. Essentially, I have found no software that can preserve alpha transparency when they rip bitmap subtitles and thus they require burn in to the resultant file if you want to use them directly in any Apple playback software. If you want to go this route, I have enough space to simply rip it twice, once with subtitles and once without.

What you're left with is a variety of OCR techniques that are shoddy at best as far as what I've seen on the Mac. I have heard good things about SubRip if you have any access to Windows.

Another option is to download an open SRT file and add it manually to the container. You could search for these via traditional means or give opensubtitles.org a try. YMMV. As long as the container format you're ripping to is mp4 (it should be if you're ripping for Apple devices), you can use Subler to add the external SRT track in post.
