While I'm sure this is a useful video I can't make it through much of it. This isn't a comment on the actual content. I've been blessed/cursed with the ability to hear sounds more high pitch than the average person. Not that much higher but enough that certain old TVs and Monitors drive me nuts. Your video has a constant high pitched whine in the background that gives me a headache. I'm not sure what the source is or what you can do about it but I figured I should warn you.
Oh my ears are quite fried and I could hear it, made it impossible for me to watch the video as it started giving me a headache almost immediately.
