Machinima

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, a glitch which raised a characters head if their gun was pointed at the ground, and panning using editing software. In Halo 2, it was filmed using the cease-fire trick, which left only the the heads-up display to be edited out in post-production.

Halo 3 's Theater is extremely useful to machinima makers. Theater mode allowed machinima makers to record in game and then go back and view it from different angles. The camera was no longer tied to a character and could fly through the air, allowing for more free filming and more natural pans.
