Machinima
From Halopedia, the Halo wiki
Template:Ratings Machinima is a type of CGI filming style in which a movie or animated short is filmed using 3D models from video games. Red vs Blue is a popular machinima made using the games in the Halo Trilogy.
Machinima in Halo: Combat Evolved, such as Red vs Blue (seasons 1, 2, and 3), was filmed using the pistol and panning using editing software. In Halo 2, it was filmed using the cease-fire trick, which left only the the HUD to be edited out in post-production.
Halo 3's Theater is extremely useful to machinima makers.
