Film transport apparatus for a cine-video system in which video signals are produced from film that is driven between supply and take-up reels. The film, which may be wound in A or B configuration on each reel, is threaded automatically about a film drive mechanism which transports the film from the supply reel, through a film gate to the take-up reel. Tensioning apparatus imparts tension to the film at the entry and exit of the film gate which, during the threading operation, causes the respective reels to rotate before film actually is transported therebetween. The direction in which each reel rotates to unwind film therefrom when tension is imparted serves to identify whether the film is wound in A or B configuration. Advantageously, a programmable processor controls the film transport speed in response to a user-actuated knob; and this same processor serves to detect when the film approaches its end on the supply or take-up reel.
