Matthew Marshall is the lead animator at Aardman Animations, a leading stop motion animation studio. He gives a presentation summarizing the history and types of animation. Stop motion animation takes many photos of slight movements to create frames. 2D animation can be traditional animation by hand or vector animation on computers. CGI animation is now common in films. Early pioneers experimented with animation devices and techniques that evolved into stop motion and film animation. Modern animators like Tim Burton and Aardman continue advancing stop motion techniques. Animation is widely used in video games and other media.
