What is previs?

Quick answer: Previs, short for previsualization, is a rough early version of a film's scenes, made before the real shoot, to test pacing, blocking, camera and dialogue while changes are still cheap. It used to mean storyboards and animatics; now many teams use generated video. In SceneMixer a voiced, rough version of a scene or a pitch trailer is a common use: it shows tone, cast and pacing, not a finished broadcast.
