I'm using this with the Resilio version of the video files so I made the script output filenames to match. This should facilitate any automatic loading of subtitles that your video player might do. It could also be useful for other sources of the video (and pretty straightforward to tweak the script to change the output filenames if you want to).
Hopefully someone else will find this useful, so I'm posting here to share. It's on a gist at https://gist.github.com/joestraitiff/7654860e4ed1eb20ca79a59ee4dba1cc
