The video assist person operates the VTR (Video Tape Recorder) during production. Most film cameras include a video tap that allows the VTR to record and instantly playback what was just filmed. Since you can’t review 35mm film without it getting processed in the laboratory first, this can be an especially useful tool on set. Video assist is the term used to describe this record and playback process. Reviewing the footage instantly allows the director to confirm performances, camera focus, framing, choreography and other elements for accuracy.
