Rotoscoping is used to extract object and replace the background, create fantasy objects such as the lightsaber in Star Wars. Later the concept of rotoscoping was upgraded by VFX technicians and artists, and the technique plays an important role in live-action films. The idea of adjusting scenes frame by frame was then involved in making mattes, and the main aim was to create scenes that are otherwise non-existed in the real world. This kind of rotoscoping still exists in the digital era, only that the glass and projector are replaced by digital drawing boards and computers. It is done by projecting the live-action film stock onto glass with light and manually tracing over the image on each frame. In that way, rotoscoping turns a live-action film into a cartoon, with characters replicating all the actions of the real people, thus avoiding jerky and clunky motion in previous animations. When it was initially invented by Max Fleischer, rotoscoping (or roto) refers to an animation technique to trace over each frame of a live-action film, and draw it frame by frame onto animation papers. Depending the aim of the work, people may refer to different techniques when applying the so-called rotoscoping process.įor instance, when you search rotoscoping tutorials for After Effects, most YouTubers will teach you how to separate characters from the background, or how to remove unwanted objects without affecting the surroundings.Īlternatively, if you are curious about what is rotoscope in animation, everyone will be talking about tracing the picture and transcribing the film frame by frame.Īren't they the same thing?
