The rotoscope traced animation from live footage

Max Fleischer projected film onto paper so animators could draw over it Max Fleischer patented the rotoscope in 1915. Live-action footage was projected one frame at a time onto a glass easel, and an animator traced the figure onto paper, giving cartoons unusually natural movement. The device was later used for effects work in films such as Star Wars and Who Framed Roger Rabbit. It sits in Mondo's movies & tv collection, one of 200 facts that each trace back to the reference below.
