摘要： Method of synchronizing audio and video information 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 (12) 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 (29) 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 which are synchronized with the video information appearing on the work print. Thereafter, the audio tracks are mixed 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. The master audio finished track is then transferred in synchronism to the master edited video tape with the stored SMPTE time codes being used (14) to drive the audio film and video tape in synchronism.
