ABSTRACT:
A single integrated machine for editing, dubbing, mixing, transferring and resolving on and with a sound motion picture film. The machine contains a first two track audio tape section, a second two track audio tape section and a film transport section including an audio stripe read head. All three of these sections are mechanically coupled together to provide a frame by frame correspondence between audio tracks and film track. The audio tracks are all electronically coupled together to permit transferring of sound from any one audio track to any other audio track on a frame by frame basis. One of the audio tracks is used as a cue track to provide cue signals for the location of scenes and for the transfer of any portion of a scene from one audio track to another selected audio track.
