I know there exist approaches like EIDR (Entertainment Identifier Registry) and ISAN (International Standard Audiovisual Number). But I do not know how many movies are contained within those lists. Is there anything like IBAN just for movies?

    "As of late 2015, EIDR contains over 827K content assets (up 14% from 2014), including 143K movies, and 387K episodes of over 24K TV series." "Having a rich set of Alternate IDs for content is one of the primary goals of EIDR. This allows EIDR IDs to be used everywhere in content workflows; if an alternate ID is needed it can be found in the metadata for the EIDR ID. EIDR supports the inclusion both proprietary and other standard (e.g. ISAN) ID references." Anything non-proprietary and non-profit would be my goto, so these would be it IMO.

IMDB has a unique ID number for each movie, tv show, and episode in its database. You can see it in the URL after the "tt".

This ID is used by various media apps (e.g. Plex) to download metadata for a video.

For example, the movie Avengers: Infinity War has this URL:


so it's ID would be 4154756.
