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:

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. Step by Step Guide to Extract Subtitles from MKV. The following will take extract.srt from MKV files in only two steps as an example, it also applies to extract subtitles from VOB, extract subtitles from AVI, extract subtitles from TS, MP4, MOV, WMV, FLV, DV, 3GP, RMVB, MPG, and etc. Bluestacks download for windows 7.

Tools such as ffmpeg or the mkvinfo command from the MKVToolNix toolkit can be used to view and extract information from recording files.

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).
