Animation

Stop motion: (or frame-by-frame) is an animation technique to make a physically manipulated object appear to move on its own.

Claymation: A service mark used for an animation process in which clay figurines are manipulated and filmed to produce an image of lifelike movement.

Pixilation: Movies. animation of people, where performers change their positions slightly between exposures of one or two frames each, to obtain a comic effect of jerky movement when the film is projected at normal speed.

These are the types of animation you told us about. So there they are...with definitions! Hurray!
