I really admire these types of instructional videos. It is refreshing to see this amidst the constant barrage of "HIT SUBSCRIBE AND LIKE!!!" on YouTube. It reminds me of old instructional videos such as [1], [2] and [3]. These days, seldom do you see non-sensational, purely informational and straight forward videos without intense music, sponsorships and sleezy tricks (click bait thumbnails) to draw viewers in. I would pay for content like this and we need to encourage film makers.
You can always modify the speed of an HTML5 player, like Vimeo's. Unfortunately, they don't expose the controls. Fortunately, you can modify it in JS by setting the playbackRate property.
Here're my two bookmarklets, that work on all non-iframe HTML5 video (alas, it doesn't work through an iframe boundary, because of the iframe security model).
