Citations of video recordings, like citations of sound recordings, will vary according to the nature of the material. Any facts relevant to identifying the item should be included. Indexed scenes are treated as chapters and cited by title or by number. Ancillary material, such as critical commentary, is cited by author and title. Note that in the Monty Python example, the citation is of material original to the 2001 edition, so the original release date of the film (1975) is omitted.

Citations of online multimedia must thoroughly identify the material cited by incorporating the elements discussed and exemplified throughout this section; it is never enough simply to cite an electronic file name or URL, though this information should be included as well. If no date can be determined from the source, include the date the material was last accessed. (See also 14.4–13.) If the material is a recording of a speech or other performance, or if it is a digital version of a published source, include information about the original performance or source. Whether to list information about the original or the digitized copy first will depend on the information available and is usually up to the author. Include an indication of the source type (e.g., “video”) and length. Note the idiosyncratic capitalization and spacing in the second example, preserved as an aid to identifying the source; this approach, if used at all, should be reserved for sources that have no ties to any publishing body (and any outright errors should be indicated in the text or note; see also 13.59).
