Rotoscope -
1. In computer graphics, to rotoscope is to create an animated matte indicating the shape of an object or actor at each frame of a sequence, as would be used to composite a CGI element into the background of a live-action shot.
2. Historically, a rotoscope was a kind of projector used to create frame-by-frame alignment between filmed live-action footage and hand-drawn animation. Mounted at the top of an animation stand, a rotoscope projected filmed images down through the actual lens of the animation camera and onto the page where animators draw and compose images.
roto - An abbreviation for rotoscope, or for the animated masks produced by the rotoscoping process.
