Classification of multimedia works. The content of the multimedia work determines which class is appropriate for registration. For example, the presence of a series of related images makes the work audiovisual in nature, and registration is generally appro­priate in Class PA. See section 490 et seq. for a discussion of multimedia works that do not include an audiovisual element.

Motion pictures. Motion pictures are audio­ visual works consisting of a series of related images which, when shown in succession, impart an impression of motion, together with accom­panying sounds, if any. 17 U.S.C. 101.

Requirement of fixation. To be eligible for copyright protection, a motion picture must be fixed. See Chapter 200: COPYRIGHT­ABLE MATTER -- IN GENERAL. A telecast transmission of a live performance is not considered a "motion picture." However, a motion picture is created when an authorized fixation is made of a live performance or telecast.

1)

3)
