Well, technically there's Vampire: The Requiem. It's very similar, but not in the exact same universe. Some of the names are reused, but there's no canon metaplot, and many details are changed. I personally liked it a lot, but I think it's less popular than Masquerade.
If you want to roll your own setting, I bet there are generic systems that would work. Fate is my go-to, and I can see how it would work. (Probably a stress track for hunger, some consequence boxes for becoming a monster)
Well, yeah. YouTube is a trash platform and pre-recorded video is a dubious medium for teaching.
The platform is trash because the incentives are not aligned with noble goals like "teach people things" or "spread the truth". It's "Get engagement" and "get ad impressions". They also don't moderate it much, so there's a ton of slop and lies.
Video is passive. it's easy to space out or just let it go in one ear and out the other. Most people learn in other ways. An actual lecture can have some back and forth, and a good teacher can engage a class. Books require more concentration. Doing exercises of some sort also force you to practice, and retain it. You could maybe do okay with video if you took notes (by hand I'm told is better), or otherwise engaged with the material in an active manner.
Also, dozens of videos a day? Go do something else. Read a book. Exercise. Play chess. Write something. Sign up for a class and attend. That's so much passive intake you're going to turn into a potato.
