Below is a simple command to shrink an mkv file using ffmpeg -- i.e., convert mkv to mkv -- and keep all existing subtitles and audio tracks (which is NOT ffmpeg's default). You can use this overnight to shrink 25 GB MKV files to around 5 GB or so -- i.e., 80% smaller.

The DockerFile instruction VOLUME [ "/data" ] creates an anonymous volume mounted as /data that allows just 1 container to use it (unless you issue a docker run --volumes-from or bind mount it with docker run -v /var/lib/docker/volumes/9283:/data) until you docker rm that container. After docker rm, the volume remains but it's inaccessible by containers without a bind mount.

I often need to enter the International Phonetic Association's (IPA) or other math symbols into my computer, often during a lecture, when speed matters. Some great webpages, particularly this one, explain how, but they require you to know the Unicode code numbers. That is far too cumbersome for me. My approach is a little different, and much more intuitive.
