Abstract: A telecine machine has a solid state sensor before which film is driven at a constant rate. To overcome differences between the film frame and television field utilization ratios, i.e. the proportion of the vertical scanning extent which is occupied by active information, and/or differences between the film frame rate and television field rate, an output signal is obtained in the form of a first sequential television signal of non-standard type, which is electronically converted to a second interlaced-scan standard signal. For example to obtain a 625/50 signal from 35 mm film, a 723/50 sequential signal is first generated, and from 8 mm film a 625/331/3 sequential signal is first generated.
