Thank you for posting, @Jville ; this was super-educational for me. I hear announcers reference these formations all the time, but until now it's kind of sounded like they're just making up terms. Going forward, I will have a much better understanding of what they're talking about.
One observation: Tight ends are shown in almost all of these formations, but in only two (Spread and Jumbo) does the voiceover really talk about what the TE does when the offense is set up that way. This video could be more complete if it touched on the tight ends' role(s) in all the formations and how the position can be used to counter various defenses.
