ABSTRACT:
A method for digital motion picture film enhancement comprises receiving a digitized source motion picture image stream. The digitized source motion picture image stream may be recorded at about 30 frames per second (fps) and is based on an original motion picture film that was filmed at an original frame rate of 24 fps or less. A first intermediate digital image stream corresponding to and having the original frame rate is extracted. Motion interpolation is performed on the first intermediate digital image stream, resulting in creating and storing a second intermediate digital image stream of about 60 fps. Pairs of frames of the second intermediate digital image stream are digitally selected and digitally interweaved to create composite frames. The composite frames are resized, and interlacing half frames are selected to result in an output image stream of about 30 fps. Embodiments significantly enhance motion fluidity of historic telecine transfers and other filmed material.
