Means for post-production film-making

Claim 2

A motion picture film which includes a row of sprocket holes along one marginal edge portion and a longitudinally extending area carrying a photo-sensitive layer for photographing a selected scene, or series of scenes in a succession of stationary frames, said film being characterised in that one of its marginal edge portions carries a latent-image numerical identification of each of said successive frames in binary code form adjacent each said frame, said binary code extending along said marginal edge such that information corresponding to individual digits is spaced in the longitudinal direction of said film, the coded information for each separate digit extending transversely across said film, said binary code including a start pulse initiator, and a plurality of equally spaced sync pulses each corresponding to and locating a separate digit identified by further coding, and wherein all coding information corresponding to any one frame is simultaneously imprinted onto said film.

Claim 3

A motion picture film as claimed in claim 1 wherein said binary code extends along said marginal edge such that information corresponding to individual digits is spaced in the longitudinal direction of said film, the coded information for each separate digit extending transversely across said film.

Claim 4

A motion picture film as claimed in claim 2 wherein said binary code includes a start pulse initiator and a plurality of equally spaced sync pulses each corresponding to and locating a separate digit identified by further coding.

Claim 5

A motion picture film as claimed in claim 3 wherein all said sync pulses for one binary number are simultaneously imprinted onto said film.

Claim 6

A motion picture film as claimed in claim 1 wherein said binary code includes information indicative of a predetermined number of consecutive frames as well as information uniquely identifying each frame within said predetermined number.

Claim 7

A post-production film making system for handling processed motion picture film and a corresponding synchronized magnetic audio medium, said film including a succession of stationary frames, the system being characterized in that the film includes along one of its marginal edge portions a series of binary coded numbers each uniquely identifying an adjacent frame in said succession of adjacent frames, said film also including along said marginal edge coding to indicate a start pulse initiator and a plurality of equally spaced synchronization pulses, the coding for each synchronization pulse corresponding to and locating a separate digit identified by said binary code, said system being further characterized by means for detecting said number code, said start pulse initiator code and said synchronization pulse code, means in response to the detected number code, start pulse initiator code and synchronization pulse code for sequentially encoding each of said numbers on to said magnetic medium at that portion of said medium corresponding to the particular frame identified by that number, and means for reading and visually displaying in arabic form, the numbers on said film and said magnetic medium.

Claim 8

A post-production film making system for handling processed motion picture film and a corresponding synchronized magnetic audio medium, said film including a succession of stationary frames, the system being characterized in that the film includes along one of its marginal edge portions a series of binary coded numbers each uniquely identifying an adjacent frame in said succession of adjacent frames, said film also including along said marginal edge coding to indicate a start pulse initiator and a plurality of equally spaced synchronization pulses, the coding for each synchronization pulse corresponding to and locating a separate digit identified by said binary code, said system being further characterized by means for detecting said number code, said start pulse initiator code and said synchronization pulse code, means in response to the detected number code, start pulse initiator code and synchronization pulse code for sequentially encoding each of said numbers on to said magnetic medium at that portion of said medium corresponding to the particular frame identified by that number, and means for reading and visually displaying in arabic form, the numbers on said film and said magnetic medium.

Claim 9

A system as claimed in claim 6 wherein said magnetic medium is full coat magnetic tape.
