Rotoscoping is an animation technique in which animators trace over live-action film footage, frame by frame, to produce animated sequences whose motion closely matches real human or animal movement. Patented by Max Fleischer in 1917 and used extensively by Walt Disney Studios for realistic character motion in early animated features, rotoscoping was later applied to distinctive stylized effect in films including Ralph Bakshi's animated features and Richard Linklater's Waking Life and A Scanner Darkly, and its underlying frame-by-frame tracing principle continues in modern digital, motion-capture-assisted animation workflows.

Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action. Originally, live-action film images were projected onto a glass panel and traced onto paper. This projection equipment is referred to as a rotoscope, developed by Polish-American animator Max Fleischer.
Frequently Asked Questions
What does a rotoscoping animator actually trace?
A rotoscoping animator traces over live-action film footage, frame by frame, redrawing each frame's figures so the resulting animated sequence closely matches the timing and motion of the real filmed performance. Patented by Max Fleischer in 1917, the technique was used by Walt Disney Studios for realistic character motion in early animated features, and later applied to distinctive stylized effect in films including Richard Linklater's Waking Life and A Scanner Darkly.
Did Max Fleischer's rotoscope patent stop other studios from using the technique?
No. The patent had expired by 1934, and rotoscoping still took heavy manual rework despite being meant as a shortcut.
No, not for long. Fleischer patented the rotoscope process in 1917, and the patent had expired by 1934, after which other studios were free to use frame-by-frame tracing without licensing it from him. Despite being conceived as a labor-saving shortcut, rotoscoping proved surprisingly time-consuming in practice, since traced frames still needed reworking to keep outlines consistent and figures reading as solid from frame to frame.
