show-reel.

A showreel is a short video showcasing a person's previous work used by people involved in filmmaking and other media, including actors, animators, lighting designers, editors, video games and models. Usually 2 to 3 minutes in length and consisting of footage from different projects, a showreel typically supplements a résumé and is used to promote the person to talent agents, producers, and casting directors. A voice actor may create an audio-only showreel, a voice reel, for the same purpose.
