Format conversion of digital video signals, integration of digital video signals into photographic film material and the like, associated signal processing, and motion compensated interpolation of images

A method of converting an input 60 field/s 2:1 interlace scan format digital video signal to an output 24 frame/s 60 field/s 3232 pulldown format digital video signal, comprising the steps of:

• forming a first series of 60 frame/s progressive scan format frames from the fields of the input signal;
• forming a second series of 24 frame/s progressive scan format frames from the first series of frames such that at least every other frame in the second series of frames is produced by motion compensated interpolation between a respective pair of successive frames of the first series of frames;
• forming alternately odd and even fields from the second series of frames such that one field in every five is a repeat;
• and
• forming said output 24 frame/s 60 field/s 3232 pulldown format digital video signal from the alternately odd and even fields formed from the second series of frames.
