Method and system for picture-correct transfer of motion picture film scenes to magnetic tape

System for picture-correct transfer of motion picture film scenes on a television recording tape in a television system operating at 60 fields per sercond comprising

• a central process computer and common controller (1);
• a telecine forming a motion picture film scanner (3);
• a video tape recording apparatus (5);
• a machine control interface (2) coupled to the telecine (3) and a second machine control interface (4) coupled to the video magnetic tape recording apparatus (5);
• means (7) coupling the telecine (3) to the video tape recording apparatus (5) for transmission of video signals from the telecine to the video tape recording apparatus (5);
• said telecine generating a sequence of pulses (FIG. 1:
• graph c) which have a frequency which is characteristic for the scanning repetition frequency at all occurring film speeds;
• means (12) for transmitting the generated sequence of pulses from the telecine to the central process computer and common controller (a);
• and
• connection means from the central process computer and controller (1) both to the telecine (3) and the video tape recording apparatus (5), with the respective machine control interface (2) interposed, to control operation of the telecine (3) to scan the film at a time when a selected frame of the film is before a scanner of the telecine and, simultaneously, and based on said generated sequence of pulses, controlling operation of said video tape recording apparatus (5) to record information on the recording tape.

Method for the picture-correct transfer of motion picture film scenes to magnetic tape, utilizing a telecine (3) and a video tape recorder (5) to record film scenes in accordance with television transmission standards operating at 60 fields per second,

• comprising
• generating a sequence of pulses (FIG. 1:
• graph c) in the telecine which have a frequency which is characteristic for the scanning repetition frequency at all occurring film speeds;
• transferring the sequence of pulses from the telecine (3) to a common control means (1);
• and
• controlling, by the common control means (1), the telecine (3) relative to the video tape recorder (5), based on said sequence of pulses, in such a way that the relative position of the film picture selected for the transfer, as related to the pulse sequence (FIG. 1:
• graph c) is such that the field calculated based on said sequence, and on the film, will be recorded on the magnetic tape in accordance with television transmission standards.
