A pin-registered film transport assembly provides an interlacing motion for moving and guiding a photographic film through a film gate. The assembly includes a first carriage mounted for movement parallel to a direction of film travel and a first pin assembly including a first pair of registration pins which are engageable in oppositely disposed perforations of the film, where the first pin assembly is mounted on the first carriage for movement perpendicular to the direction of film travel for engaging and disengaging the film perforations. The assembly also includes a second carriage mounted for movement parallel to the direction of film travel and a second pin assembly including a second pair of registration pins which are engageable in oppositely disposed perforations of the film, where the second pin assembly is mounted on the second carriage for movement perpendicular to the direction of film travel. The carriages and pin assemblies are moved and controlled such that the first pair of registration pins engages the film perforations at a starting position and moves the film in the direction of film travel while the second pair of registration pins is repositioning to the starting position for engagement with another pair of perforations. This action is then repeated to provide improved movement of the film through the film gate, particularly by reducing the time latency during pin retrace motion.
