I guess I'm old and out of touch after only a bit over three decades, because I can't figure out why this would helpful to have as a video in the first place over the text summary you posted here. I could see screenshots maybe being slightly helpful, but to having this sort of thing as a video feels like an extreme inconvenience; I'd much rather see all of it at once and be able to visually scan (or even better, ctrl+f) to find specific parts over having to scrub around if I wanted to go back to a previous part or skip ahead. My eyes also don't require any sort of manual timing to pause on something I want to copy.
