Abstract
A cinematographic camera is operated at three times normal frame rates and converted to digital video in a telecine operation. Motion estimation provides from the digital video motion vectors which are substantially free of temporal aliasing. These motion vectors are employed in film weave measurement and correction and in motion compensated noise reduction and scratch concealment to provide a high quality signal which can be displayed at the elevated frame rate or standards converted, using the high quality motion vectors, to any desired standard.
