I think though the biggest things not covered in that video for cricket was the ability to get a wicket by either
a) knocking it off with a bowled ball (which is basically what the bowler/pitcher is trying to do) or
b) knocking the wicket off by a fielder who throws the ball on a hit play and is able to get it there before the runner crosses the "safe" line, which is like a forced throw out in baseball.
Finally c) if you don't hit it over the boundary line (the 6 run HR he refer to) but rather hit it to the boundary line (or it hops over or whatever) that's 4 runs.
Else the rest is pretty much like baseball, just you're in the center of the field so there is no such thing as a "foul" ball, and the batter can for example just jack one completely behind him if he's able to.
There's some weirdness things but those are pretty small in terms of the grand scheme of the game.
