What is an "audiovisual work"?
The ISAN standard defines an audiovisual work as a work consisting of a sequence of related images, with or without accompanying sound, which is intended to be made visible as a moving image through the use of devices, regardless of the medium of initial or subsequent fixation.
Examples of the types of audiovisual works to which ISAN may be assigned are: motion pictures (e.g. feature films) and short films, trailers (i.e. previews, productions for television or other means of delivery, including individual episodes of television series, industrial, educational and training films, commercials, broadcasts and recordings of live events (such as sports events and newscasts), video games, music video clips, composite and multimedia works if they contain a significant audiovisual component, as well as non-linear works including compilations.
What is a Version of an audiovisual work?
ISAN identifies audiovisual works as distinct intellectual creations. A version consists of changes within a work, or the aggregation of elements that affects the content of an audiovisual work as long as it does not result in a new intellectual creation.
Changes such as editing, the addition of subtitles, dubbing, alterations of the soundtrack (all to be considered as “variants” of the work), fixation of the content on a specific media (Film print, Blu-ray, digital file ...), the change of technical properties (HD/SD, encoding format...) (all to be considered as “manifestations” of the work), as well as content or items closely related to the work (“related content” or “related items”), can all result in the issuance of a new ISAN version or “V-ISAN”.
