A method is disclosed whereby motion pictures photographed and exhibited at high frame rates, typically 48 frames-per-second, are modified to impart a cinematic appearance which tempers the level of motion detail inherent at such high frame rates. Motion pictures can be photographed either on film or by digital means. A controlled amount of motion blur is imparted selectively to certain scenes, sequences, frames or components of images. This can be accomplished by using different shuttle angles for digital photography, or by imparting motion blur in post-production. The result is a motion picture that retains a cinematic appearance, at least in part, while other parts of the same motion picture appear hyper-realistic, due to the high frame rate of photography and exhibition.

For each cue, a determination is made automatically of the prefire interval, that is, the interval by which the cue should be advanced. The execution the cue to trigger a corresponding activity is advanced by the automatically determined pre-fire interval.
