Useful context from the subtitle: > Super slow motion clips supports "The Illustrated Principles of Pool and Billiards" Down that rabbit hole a bit further: https://drdavebilliards.com/videos/high-speed-video/ https://drdavebilliards.com/videos/high-speed-video/ > The HSV DVD contains numerous narrated super-slow-motion video clips filmed with a special high-speed video camera. I note a (c) 2007 on the DVD's label image on the website, which probably explains the video quality. Given that there are at least ~25 other instructional DVDs included in various sets for sale, I get the impression that these videos are essentially online for free because they're not really useful without either having purchased the coursework or being enough of an expert that you don't need the coursework anyways. Still neat, though.
