I made an habit to draw without feeling motivated. It's something that you'll learn eventually as you shift to make your comic a responsability.
Personally speaking I don't require much inspiration with videos, I'm more of a music person, sometimes I get hyped to work while listening to Utsu-P's "Greatest Shits" album. Sometimes with My Chemical Romance's "Danger Days: The true lives of the Fabulous Killjoys".
But if you're seeking for videos, I believe that watching animes such as Blue Period, Keep Your Hands Off Eizouken!, Ping Pong the Animation, Bakuman or even Re:Creators are actually very inspiring. You could also watch the process of other artists such as Shinichi Sakamoto (Innocent), Yuumei (Webtoon artist) and many more.
