Behind The Scenes
From Halopedia, the Halo wiki
"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.
