Cutscene

In the Halo series, a Cut Scene is an in-game cinematic movie rendered using in game resources. These cut scenes are usually played before or after a campaign mission. They are sometimes played during a mission. Because Halo cut scenes are not pre-rendered, they can be altered by moving objects into the location where the cut scenes will take place before it begins. Some cut scenes are rendered in locations not accessible to a normal player. These locations for cut scenes are generally located very far out of a map such as the Secret Room On The Ark can only be accessed via Theater Mode. For the locations that are farther out of the map, Pan Cam will be required to reach those areas. Some locations for cut scenes cannot be accessed at all.

Glitches

 * In most cut scenes, if you were to block the path of a character during the cut scene, that character would just end up walk through the object.
 * In Halo 3, certain cut scenes can be altered by other glitches such as the Time Travel Glitch.
 * If you skip a certain cutscene early during a campaign mission, then the events in the cutscene will still continue in-game. This can be observed in Halo 3, on the level The Covenant when you are de-activating the towers. If you skip the cutscene right away, you can still see the towers deactivating.
 * Sometimes the music in a cut scene may not load or may become out of sync with the video. This is usually caused by lag.
 * In Theater Mode, if you fast forward during a cut scene, the dialouge will be cut short or overlapped with other lines.
