Let me emphasize it - thanks to the Internet, you have access to the best knowledge and experience entire humanity has produced. All it takes is some experience with using the Internet and spending little time on filtering links.
I think woodworking is hard to qualify. So, let's simplify.
1) A master craftsman video demonstrating how to make an Italian style flat bread oven from someone that spent ~15+ years learning and building them.
2) One of those small but highly accurate mechanical clocks that's accurate enough for navigation at sea.
3) A European ed: (English) style saddle made by a craftsman, as in someone that made and sold 100 others before it.
I am sure there are at least a few hundred people with those skills world wide, but actually finding a detailed video made by one of them online seems much harder. As in something that's good enough to learn from not just advertising or a 'how it's made' video showing some highlights.
It's 3:30 EST on Friday. Let's give it 24 hours. ;)

Sure, you can find plenty of videos on how make a hard boiled egg, apply tile, or do a card trick... But, that statement seems way over the top.
PS: Though, this is one case where I would haply be proved wrong.
Those other skills form the foundation of successful online video channels, with the video skills following suit.
