Redditor jamieleto posted a fun series of classic Disney cartoons where a technique called rotoscoping was used (before computers, natch).
If you’re unfamiliar with rotoscoping, here’s some background information on the subject via Wikipedia:
Rotoscoping is an animation technique in which animators trace over footage, frame by frame, for use in live-action and animated films.[1][2] Originally, recorded live-action film images were projected onto a frosted glass panel and re-drawn by an animator. This projection equipment is called a rotoscope, although this device was eventually replaced by computers.
In the visual effects industry, the term rotoscoping refers to the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background.
Probably the most famous example of rotoscoping was A-ha’s 1985 music video for “Take on Me.”
Update: There’s some debate as to whether or not the rotoscoping technique was used for these cartoons or if they were just reference shots for the animators.
