Abstract
Editing data producing apparatus produces first data for editing a cinema film based on second editing data obtained by editing a television video signal reproduced from a record medium on which a cinema signal is recorded in a manner of the television video signal. The video signal is obtained from the cinema signal by an m:n ratio (m and n are both integers) pull-down conversion. An editing video frame address representative of an editing location of the video signal and a reference video frame address representative of the video frame address corresponding to a predetermined cinema frame address of the cinema signal are supplied to a circuit which then produces a relative address between the editing video frame address and the reference video frame address. A circuit is provided for dividing a number representative of the relative address by a number bearing a predetermined relation to m and n, so that a remainder is detected. In response to the remainder and field data representative of a field status of the editing video frame address, the video frame address is converted to the cinema frame address.
