Abstract: A method of synchronizing audio and video information is disclosed wherein standard motion picture techniques may be used to form a master finished audio track accurately synchronized with a recorded video signal. A standard master edited video tape is recorded with a conventional SMPTE time code or other code identifying each of the recorded frames. The video signal and time code are transferred to a first sprocketed magnetic film which operates at standard motion picture speeds. This film serves as a "work" print which is then used to build a plurality of audio tracks on sprocket driven films which are synchronized with the video information appearing on the work print. Thereafter, the audio tracks are mixed in synchronism to form a master finished audio track on a second sprocketed magnetic film. The SMPTE time code is transferred from the work print to the second sprocketed magnetic film in synchronism with the master finished audio track.
