Emacs as your video-trimming tool

Marcin ‘mbork’ Borkowski has a nice post showing us how he trims video clips from our beloved editor. Trimming clips is something I do from time to time, specially when posting a screencast of sorts. Since I don't need much, I typically resort to QuickTime Player's trimming functionality that ships with macOS. While it does the job, ever since I added a "graphical" seeker to Ready Player Mode, I had been meaning to build a simple video trimming tool of sorts. Marcin's post was just about the right nudge I needed to also give this a go, yielding video-trimmer-mode.

The solution relies on ffmpeg to do the heavy lifting and is roughly 300 lines of code. I was going to share the entire snippet in this post, though may as well point you to its repo. I'm likely to tweak it, so you may as well take a look at its latest incarnation.
