I loved the Kung Fu Panda movies, and their title sequences along with the credits are always really great. It's one of the only few credit sequences I actually sat and watched.

This is the intro to the show Archer, I think this sequence shows really good motion design, and some great transitions. One example is the ball jumping down onto the name.

This gif really shows motion design. With the speed lines behind the rectangle and the way it moves back it really shows speed.
