Demoreel - tabletop director's portfolio
Demo reels/showreels, in general, are used by many kinds of people involved in filmmaking and other media, including actors, animators, lighting designers, editors and others. Usually are up to 3 minutes in length. Typically a demo reel/showreel supplements a résumé and is used to promote an author to talent agents, producers and casting directors.
Outside of people and companies directly involved with video or film production, companies use showreels for brand management and other forms of marketing communications and public relations, hence, in this case, it is called a corporate showreel.
