Extract subtitles and insert into another mkv

[jbrown]

I have 2 mkv files, one with subtitles and one without. I want to extract the subtitles from one mkv file and insert it into the other mkv file. Anyone know how to do that?

mkvmerge from mkvtoolnix does this quite well. Used to use it for putting DVD subtitle tracks into BD video, for players that didn't support PGS subtitles. I got better players, though.

So what would be the basic process with the 2 apps?

Using the GUI version of mkvmerge, you load both MKV files, select the tracks from each you want in the output, name the output file, and select start.

From what you've described, you would select ALL tracks from the "target", and just the subtitle track from the donor. The process is pretty fast, so you can experiment (play) to get what's right for your needs.
