ABSTRACT:
An apparatus for transferring in synchronism, onto a common recording support, the images of an cinematographic film and the sound recorded during shooting on a separate support, comprises a telecine apparatus ensuring reading of the cine film. A microcomputer has an input connected to a reader of time codes borne by the cine film. A first output of the microcomputer is connected to a stage controlling the supply of an electric motor ensuring advance of the cine film in the telecine apparatus. A second output of the microcomputer is connected to a coder and a third output is connected to a first input of a comparator with two inputs of which the second input is connected to the head for reading the time codes on the magnetic tape, the output of the comparator is connected to a stage controlling supply of an electric motor of the servo-controlled magnetic tape recorder and the third output of the microcomputer is also connected to a device for recording time codes on the third track of the video tape.
