• a nonlinear editing system, including:
• means for permitting a user to specify scenes from the sequences of digital images stored in the data files on the random access computer readable medium, wherein a scene is defined by a reference to a data file storing a selected one of the sequences of digital images and by frame points designated in the selected sequence of digital images,
• wherein the frame points may be designated at any frame boundary using a metric based on the playback rate of 24 frames per second;
• means for permitting a user to specify a sequence of one or more specified scenes;
• means for storing information about the designated frame points of each specified scene from the specified sequence of scenes from the sequences of digital images using a metric based on the rate of 24 frames per second and a second frame rate different from the rate of 24 frames per second;
• means for updating the stored information with the designated frame points of each specified scene in response to specification of the scenes from the sequence of digital images;
