Abstract

Method and apparatus for applying encoded data on the balance stripe of sound track, the data for providing information for editing an associated film without recording the data on the film. The present invention teaches an apparatus for applying code for synchronizing sound on a single strip of the sound track with an associated film. The apparatus includes a code box for generating the code, which relates the position of the film relative to the sound track. The code box is coupled to an editing flatbed for providing pulses related to the movement of the sound track. A sound module is coupled to the code box for applying the code to the balance stripe.
