ABSTRACT:
An apparatus for listing cinematographic film comprises means (1, 2, 3, 4, 6, 7) for reversible feeding of film past an index position and for generating electric signals representing each picture frame fed past the index position and the direction in which the film is fed. A counter (8) driven by said electric signals is arranged to count the net number of picture frames fed past the index position in a given direction. Means (9, 19) are also provided for visually displaying to an operator an enlarged form of the film section located at the index position. A data processor (11) provided with a data input keyboard (12) is connected to the counter and arranged to calculate positional information concerning desired picture frames in the film, on the basis of data entered into the processor through the keyboard and the content of the counter, and to store this positional information in a data storage.
