Behind The Scenes

"BTSs", short for Behind The Scenes, are a series of video documentaries released by 343 Industries showcasing a particular feature or aspect of an upcoming game. BTS video documentaries are the spiritual successors to the ViDocs produced by Bungie and Ensemble Studios, though their running times are far less uniform than the seven-minute ViDocs, ranging from two to seven minutes.

Halo 4 had its own series of video documentaries called Making Halo 4. Halo 2: Anniversary had its own documentary movie called Remaking The Legend instead of a short series of videos.
