Rotoscoping describes the process of manually altering film footage one frame at a time. It was invented in 1915 by animator Max Fleischer to improve the movement of animated characters and make them look more realistic.
The technique was originally achieved by filming scenes in live action and then projecting the film onto glass panels so an animator could trace the action in every frame, thus capturing the movement of the actors. Adopted by Disney in the 1930s, many of their celebrated early titles like Snow White and the Seven Dwarves, Cinderella and Alice in Wonderland were all created via rotoscoping.
More recently, this manual process has been replaced by computers and adopted by the visual effects (VFX) industry to manipulate images by removing unseemly wires, placing characters in different settings or even creating the light effects for the iconic Star Wars lightsabers.
Here is a selection of films that feature rotoscoping from traditional uses through to special effects and innovative experiments that reveal the development of the animation technique and its contribution to exciting, visual storytelling across film history.
Disney's funny, beautifully drawn animated version of the classic fairytale about a lovey princess on the run from her wicked stepmother.
