![]() Rotoscoping is achieved by two methods, rear projection and front surface projection. Ĭonceived as a shortcut to animating, the rotoscope process proved time-consuming due to the precise and laborious nature of tracing. The live-movie reference for the character, later known as Koko the Clown, was performed by his brother ( Dave Fleischer) dressed in a clown costume. It was known simply as the "Fleischer Process" on the early screen credits, and was essentially exclusive to Fleischer for several years. ![]() The rotoscope technique was invented by animator Max Fleischer in 1915, and used in his groundbreaking Out of the Inkwell animated series (1918–1927). The films were traced from live-action film footage. īy 1902, Nuremberg toy companies Gebrüder Bing and Ernst Plank were offering chromolithographed film loops for their toy kinematographs. Discs made between 18 had outlines drawn by Erwin Faber photographically printed on the disc and then colored by hand, but these discs were probably never used in the lectures. The first discs were painted on the glass in dark contours. To achieve this, effects technicians traced a line over each frame with the prop, then enlarged each line and added the glow.Įadweard Muybridge had some of his famous chronophotographic sequences painted on glass discs for the zoopraxiscope projector that he used in his popular lectures between 18. A classic use of traditional rotoscoping was in the original three Star Wars movies, where the production used it to create the glowing lightsaber effect with a matte based on sticks held by the actors. Rotoscoping has also been used to create a special visual effect (such as a glow, for example) that is guided by the matte or rotoscoped line. Rotoscoping is often used in the preparation of garbage mattes for other matte-pulling processes. ![]() Rotoscoping in the digital domain is often aided by motion-tracking and onion-skinning software. While blue- and green-screen techniques have made the process of layering subjects in scenes easier, rotoscoping still plays a large role in the production of visual effects imagery. By tracing an object, the moviemaker creates a silhouette (called a matte) that can be used to extract that object from a scene for use on a different background. Rotoscoping has often been used as a tool for visual effects in live-action movies.

Chroma key is more often used for this, as it is faster and requires less work, but Rotoscoping provides a higher level of accuracy and is often used in conjunction with Chroma-keying. In the visual effects industry, Rotoscoping is the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background. This device was eventually replaced by computers, but the process is still called rotoscoping. This projection equipment is referred to as a rotoscope, developed by Austrian-American animator Max Fleischer. Originally, live-action movie images were projected onto a glass panel and traced onto paper. Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action. The artist is drawing on a transparent easel, onto which the movie projector at the right is beaming an image of a single movie frame. Patent drawing for Max Fleischer's original rotoscope.
