I haven’t read this yet but it looks relevant: Andrea Leigh, "Describing Moving Images at the Collection Level" (The Moving Image 6: 1 (2006), 33-65). The introduction says:
Traditionally, the choice in cataloging moving images has been at the item level, as description favors completed moving image works where titles and credits are transcribed from the film itself. This approach is borrowed from item level descriptive practices common in libraries. With the proliferation of digital content, increased publication and distribution of print and media material, as well as the shift in the way users access information, a reconceptualizing of this strict item level approach, considering the array of emerging standards within a variety of professional communities, is underway.
Chief among these standards is the Functional Requirements for Bibliographic Records (FRBR), a conceptual model spearheaded by the International Federation of Library Associations and Institutions (IFLA).
