I really enjoy Steve Mould’s videos on YouTube, but I’ve only just stumbled upon this one from 2020: https://www.youtube.com/watch?v=rEoc0YoALt0

It’s mainly about some pretty cool motion amplification technology that can be used to detect *and visualise* tiny vibrations before they become a problem, in factories for example

But there’s a digression into the ✨captchas✨ that we regularly encounter on the web, asking us to recognise something to prove that we’re human

I figured - we should be able to do motion amplification with ffmpeg, since it has optical flow capabilities and tools. I can't find anything about that though. I'm looking for a FOSS way to do this.
