Abstract
Abstract The present invention is a method of applying variable, momentous production information to each frame of a continuous visual image medium at the instant of use or after use, without interfering with the formation or display of the normal visual image on the same frame. The recorded production information become absolute reference points on the continuous visual image medium, enabling fast and accurate identification and retrieval at a later date. The method addresses various needs in an ever increasing market ranging from major motion pictures to home videos. The present invention is also a system of recording or retrieving the production information on each frame of a continuous visual image medium. The system includes the actual hardware for the writing and reading of the index code, and the software necessary to decode the code and translate it into useful and user readable information. The system offers producers, directors and editors the freedom to quickly identify and retrieve footage for consideration, while maintaining an accurate asset control on a frame by frame basis. The system also maximizes the usefulness and potential re-use of visual materials.

Total Claims: 18
Claim 1
Independent Claim
153 words
A method of indexing a motion picture film that is produced at a certain frame rate and contains a series of frames each having a periphery area surrounding a safe shooting area, comprising the steps of: a. generating an index rate which is consistent with said frame rate; b. inputing identification information for each frame of said motion picture film; c. encoding said identification information into an index code at said index rate; and d. while said motion picture is continued at said frame rate, imprinting said index code on said motion picture film at said periphery area of each frame of said motion picture film, such that said index code can be retrieved at a later time for identifying each frame of said motion picture film, but when said motion picture film is projected to a movie screen, said index code will remain invisible and not be shown on the movie screen.
