Motion interpolation
Motion interpolation, motion-compensated frame interpolation (MCFI), or frame generation, is a form of video processing in which intermediate film, video or animation frames are synthesized between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display motion blur, and for fake slow motion effects. In computer animation, interpolation (computer graphics) can also be a natural automated process similar to inbetweening, where each frame depicts objects moving fluidly between key frames.
