Content that combines multiple media types into a single bundled work where the bundling itself produces a new aggregated right that subsists in the combination. A music video is multimedia (audio + film + sometimes embedded text + choreography). A video game is multimedia (visual art + sound design + music + code + narrative + sometimes performance capture). An interactive ebook is multimedia (text + image + audio + sometimes video). A theatrical production captured on film is multimedia (script + performance + music + design + cinematography). The legal complexity of multimedia is the *layered rights stack*. The underlying components each have their own rights, and the bundle has its own rights on top, often held by a different party from any of the component rights holders. A music video's master recording is owned by a label; the underlying composition by a publisher; the visual footage by a production company; the choreography by a choreographer; and the assembled audiovisual work itself by yet another party. AI ingestion of a music video engages all of those rights simultaneously. In the CIP framework, content classified as `Multimedia` (per `CIP-Media-Class`, Enum 5 of CIP Classifications v1.0) requires either an enumerated list of component rights or an attached layered-rights schedule. A `cip.md` declaration with `CIP-Media-Class: Multimedia` and no component-rights enumeration is treated as incomplete — the declarant has asserted the classification but has not made the layered rights legible. Vendor contracts using the CIP Vendor Representation should specify which media class the vendor's content falls into, and where that class is `Multimedia`, should reference the layered-rights schedule by name.
