Finally giving up on ffmpeg, I asked the search engine if any other tools were able to extract image-based subtitles as rendered images/pictures from the video. Some claimed mencoder could do that and I actually found example commands, but none worked for me and all examples centered around DVD and VobSub format type of work, like writing.idx. To extract more subtitles at once you have to duplicate the -map parameters for each file. Also include -c copy so that it just extracts the file without trying to process it: ffmpeg -i Movie.mkv -c copy -map 0:s:0 subs.01.srt -c copy -map 0:s:1 subs.02.srt. Anyway it will take long time because ffmpeg must read whole video file to find all. Dvdsubtitles are image-based and cannot be converted to.srt. Try this -map 0:s:0 -c copy sub2.mkv.If you're looking to make the.sub +.idx pair typically associated with DVD subtitles, I don't know how to do that with ffmpeg, but putting them as the only track in a.mkv works for most cases. Extract subs from (non-encrypted, on hard drive) DVDs and convert to Advanced Substation Alpha format. It can also convert sup (PGS) and sub/idx formats to same. 'I wrote this because I hate the blocky, too-high-on-the-screen look of regular DVD subtitles and wanted to re-encode my DVD collection in h264/aac/assa in an mkv container.'
We extract subtitles from videos for different purposes. For example, we extract the subtitles of a low-resolution video file, and then add them to a high-resolution version for getting a better visual experience.

FFMpeg is the swiss army knife of video editors and motion artists worldwide. Let’s take a look at one of the lesser-known (and kinda unexpected) features.
FFmpeg can easily extract embedded subtitles from videos. This command will grab the default subtitle track and export it as a srt file:
What if we want to get a different subtitle? First we need to figure out the track number for that subtitle by running ffmpeg ‑i input_file. You will get an output that something like this:
Notice the tracks are numbered #0:2, #0:3, etc. This is the value we want to pass over to the map command to select the proper subtitle.
Removing HTML from subtitles
There are a number of applications and online services that can strip html tags from subtitles (like HTML Stripper), but you can also solve this quickly with good old sed:
You can make an alias to this in your favorite shell so you don’t have to remember or copy/paste it all the time. Keep in mind that the results of sed won’t be as good as a HTML stripper and company, since this is just a simple regex. That said, it’s usually more than enough for subtitles.
Converting to other formats
While FFmpeg can get this done for you with a limited number of formats (depending on how it was compiled) there is a better alternative. SubtitleEdit is a handy open source application that can convert between 200+ subtitle formats (and do a lot more of course).
