Motion picture film transport
 Motion picture film transport of the kind used in a telecine apparatus uses a common film lacing path between a picture gate and a sound gate for films of different gauges. An audio delay circuit delays the audio signal generated at the sound gate for at least one of the film gauges to maintain synchronism between the audio and video output signals.
