This letter presents an algorithm for detecting cross-fade scene changes in video carrying 3:2 or mixed film cadence. There are many existing methods for detecting gradual video transitions, but none of the current literature addresses the complication of film cadence. The differences between video and film capture and the mechanics of the telecine transfer process used to convert 24-Hz film to the main international television standards alter the temporal properties in a nonlinear way that makes cross-fades more difficult to detect with existing methods. An algorithm is proposed to address this problem.
