Stupid essay is stupid, but I'm glad it pointed me to lossless-cut because that tool is great! The author completely misses the point of Chromium in berating lossless-cut for being "a graphical UI for two ffmpeg flags". Yes, exactly, it's a GUI that lets you cut video to the precise frame you want to. That exactly solves a problem I've had for a long time; I've been using a horrible ffmpeg command line alias (along with preview in VLC) for a year now. He's a little right about "It doesn’t even use ffmpeg to decode the video preview in the app"; that would be useful for supporting weird formats that Chromium doesn't. But for common formats lossless-cut is great. It's at https://github.com/mifi/lossless-cut
