ABSTRACT:
A method of encoding video display data, after that data has been previously converted from a film frame rate to a faster video frame rate, such as by 3:2 pulldown. The data is first re-converted to the film frame format, as progressive frames (21). This progressive frame data is processed to determine where scene cuts occur (22). The data is then encoded consistent with MPEG encoding techniques, but with the scene cut information being used to begin groups of pictures (GOPs) at scene cuts and to determine where intrapictures, predicted pictures, or interpolated pictures shall occur (23).
