then i possibly could get away by uploading an entire movie while cutting every 5th frame. Or not? I'm not showing the movie's entirety too, am I?

No, but in a perfect world that would be logical.

In our imperfect world, though, movies and games are different. Since Let's Plays are part of a cinematic medium and video games are part of an interactive medium they aren't considered competition, whereas movies are part of the same medium as Let's Plays. So that's why that wouldn't be legal.
