The Movie Database (TMDB) is an editable database of films, and alternative to imdb with an apparently easier to use API, so is preferred by a site I use called Letterboxd.

When adding a video to a film entry (for example a trailer), instead of adding the video's URL you add what they call a video key. For Youtube thisis in the URL, so it's easy to find, but to find it for Vimeo you have to:

1. Click on the 'Share Video' button
2. Look through the code in the 'Embed' section, for example:

   • <iframe src="https://player.vimeo.com/video/158111029" width="640" height="480" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe>
     <p><a href="https://vimeo.com/158111029">BLACK MAN&#039;S HOUSES</a> from <a href="https://vimeo.com/roninfilmsaustralia">Ronin Films</a> on <a href="https://vimeo.com">Vimeo</a>.</p>

3. Find the URL with the nine-digit sequence, and use the numbers from that:
   • https://vimeo.com/158111029
   • 158111029
