Today English Wikipedia features article is

https://en.wikipedia.org/wiki/Sagitta

It mentions
https://en.wikipedia.org/wiki/IAU_designated_constellations

Is there some kind of video (up to 1 hour, say) that lists those and explains somehting about the standard constellations and what's out there and known. A basic 101.
I tried to search on youtube but I find nothing like an overview
