Each time the operator is projecting the start or end of what is to become an audio scene, he presses a store switch, commanding storage of the current frame count, thereby defining all the audio scenes on the film one after the other, for subsequent recording work. Thereafter, during recording work, the projector is referenced to the start and end frame counts of one scene at a time, one scene after another, as the operator controls semiautomatic recording work on successive scenes. A green, red and yellow indicator lamp are arranged in left-to-right order. When the film is ahead of the start of the referenced scene only the green lamp is bright, when past the end of the scene only the yellow, when in the middle of the scene only the red, when at the exact start of the scene both the green and red, when at the exact end of the scene both the red and the yellow.
