I'm curious what the issue is with using Handbrake? I use it all the time on macOS and it's generally a simple and effective tool for my purposes.

Handbrake is fine if you truly need to reencode (aka “transcode”) your video, but if you find yourself with a video that your player can’t read, you might be able to just change the container format (remux it) using ffmpeg, copying the video and audio streams directly across.
With video there are 3 formats: the video stream itself, the audio stream itself, and the container (only the container is knowable from the extension). Formats could technically be combined in any combination.
The video stream especially is costly in CPU to encode, and can degrade quality significantly to transcode so it’s just a shame to re-encode if the original codec is usable.
Container format mkv is notorious for not being supported out of the box on lots of consumer devices, even if they might have codecs for the audio and video streams they typically contain. (It has cool features geeks like, though, but for some reason it gets less support.)
If you search the page you'll find a reference to having “numerous foot guns”.
I can't say I've experienced either of the ones mentioned, but I have had trouble in the past with output resolution selection (ending up with a larger file than expected with the encoding resolution much larger than the intended display resolution). User error, of course, but that tab is a bit non-obvious so it might be fair to call it a footgun.
the author can't stand how it simply re-encodes videos instead of extracting the video tracks and puts them in new containers.
