Twixtor is a proprietary optical flow plugin for video editing software (After Effects, Vegas Pro, etc.). Unlike traditional slow motion, Twixtor analyzes the pixels between frames, inventing new frames to create buttery-smooth playback. It tracks vectors—how a tear rolls down a cheek or how blood splatters in the air—and morphs the image to fill the gaps.
