Marking of interspersed motion-picture scenes and still shots with interrupt-transport markings

In an apparatus for recording motion pictures on a recording medium, in combination, means for recording successive image frames on successive portions of the recording medium;

• and marking means operable by the user for providing the recording medium with interrupt-transport markings correlated with predetermined image frames, whereby when the recording medium is run through a reproducing apparatus provided with a marking detector the detection of the interrupt-transport markings can be used to interrupt recording medium transport and persistently reproduce the predetermined image frames as still images, the recording medium being photographic motion-picture film provided with film-frame perforations running alongside one longitudinal edge of the film, the marking means comprising cutting means for making cuts in the film extending transversely to the direction of elongation of the film from such perforations to the nearer of the two longitudinal edges of the film, the apparatus including a film transport mechanism, the film transport mechanism including a film transport claw which enters into film perforations for intermittent transport of the film, the cutting means being provided on the film transport claw and normally not cutting the film, and furthermore including means for displacing the transport claw into a position in which the cutting means cuts the film and produces an interrupt-transport frame marking.
