Rotoscoping

Rotoscoping is a type of animation technique where animators trace over live-action movement, frame by frame. Previously, rotoscoping was done by projecting recorded live-action film images onto a frosted glass panel and then redrawn by an animator. The projection equipment, called a rotoscope, has since been replaced by computers.

The technique of rotoscoping is often used as a tool for visual effects in live-action movies. By tracing an object, you can create a silhouette that can be taken from its original scene and placed on a different background.

Posted below are a couple different examples of rotoscope animation. I really enjoy how differently rotoscope animations can differ just based on color, background, or the amount of detailed traced over.
