"ViDocs" are video documentaries created and released by Bungie, later by Ensemble Studios and now by 343 Industries, showcasing a particular feature in an upcoming game, that run for roughly seven minutes (except for Journey's End). These videos give players insight into the creative development processes involved in the progress of Halo 3, Halo Wars, Halo 3: ODST, Halo: Reach and Halo 4.
Most ViDocs have a title in Latin that is somehow related to the content of the videos. Other ViDocs reference famous quotes, such as "Once More Unto the Breach" and "On the Seven7th Day...". These ViDocs contain interviews of various Bungie employees working on that aspect of the game in question, and a great deal of game footage.
