Here are some advanced youtube search operators. They even work in google if it's not necessarily on youtube but on a random site. >older than 2008 before:2008 this is the easy part now here comes the hard part old videos like that only have usable keywords in the title and the description so you have to remember what it might have been and not the content of the vid. >I'm certain it should have been available for the masses at 2020 Now this is the annoying part... Around 2020 google went crazy with it's algorithm. They started to censor and ban things so the advertisers don't go mad for making their ads appear on weird conspiracy/rightwing vids. Then they started to "auto-curate" the web with it. And the worst part was when the auto-copyright claim algorithms started to work. So if your video is copyrighted documentary and not something of a verified channel that is maintained till nowadays then it might be deleted. Or if it's some dude just talking but it has some background music it can also get auto deleted. An old video like that only has a chance when it's some random dude talking into the camera with no background music. 2008... that was the time I started to get seriously addicted to the internet. Now it's so shit that it's hard to stay addicted. But then again I am still here so I am still not over it.
What you wrote is still to vague. But then again it's the journey not the destination. Just looking for the vid gives you enough yoga knowledge on the path. You need to figure out the really important parts by yourself anyway.
