Most people good at making videos have better things to make videos on than random niche hobbies and crafts. If you step out of the popculture, you'll see a lot of videos made by those who do the work.
I'm subscribed to YouTube channels devoted to crafts such as woodworking, cooking, metalworking, development, sewing, drink mixing, and others, and very few of them use professional equipment or editing software. Some of the most entertaining ones do, of course, but mostly because they started small and were able to grow their audience enough to turn it into a career, over the course of which they picked up the skills to improve the quality of the videos.
Those other skills form the foundation of successful online video channels, with the video skills following suit.
Yea, there are plenty of people worth following out there. But, a few minutes of random searching is probably not going to show you one of the gems. Unless, I am just bad at finding videos.
Consider then finding an on-line community of enthusiasts first. Like, in case of woodworking, /r/woodworking and some of the other subreddits listed in the sidebar there. Spend few minutes there, and you'll know where to find the best 5% of woodworking sources available to mankind.
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 your vastly overstating what videos people put online.
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. ;)
Moving the goalposts to the furthest conceivable distance isn't going to prove anything to anybody. Nobody claimed you could completely master a trade skill just from watching YouTube videos.
IMO, there is a fair amount of. "Those who can do. Those who can't teach."
Sure, you can find some videos of people making a wooden clock online. It's much harder to find master craftsman making a watch. A few PHD students putting together an electric car vs. someone at GM actually designing a car. Home cook vs. Five Star Chef.
Granted, generally an amateur is fine. But, don't be surprised if there making several mistakes without noticing.
> IMO, there is a fair amount of. "Those who can do. Those who can't teach."
That applies to occupations, not to hobbies. I.e. those who can't find a proper job using their skill go on to teach that skill.
It does not however apply to the most valuable content - one made not for money, but out of love for the subject. A lot of masters in all occupations simply like to share. Our industry is probably the best example - it's almost entirely built upon masters who gave away their knowledge. But it happens in other industries too.
