ABSTRACT:
Apparatus for converting, for example, 24 Hz 1:1 format film to, for example, a 60 Hz 2:1 interlace format video signal comprises a converter (12) for transferring 24 Hz 1:1 format film material to a 60 Hz 2:1 interlace format video signal using 3 2 3 2 pull down, and a coder (13) associated with the converter (12) for associating a 10-field sequence identifier with the video signal. The 10-field sequence identifier is used to maintain identification of the phantom fields and the field sequence through subsequent processing, and in particular to control motion processing.
