Continuity

Continuity is a type of editing used in films or short clips that creates action which will flow across different shots, slotting them together with the scene still making sense and the audience knows what it happening. Continuity is basically a continuous condition of the character/props that have been used. 

As an example for this, a character should look exactly the same in a scene although it could be filmed on different occasions. They should remain wearing the same thing, and using the correct props in the correct way as they did in previous shots. 

Another reason for continuity to be used is because they can cut down a scene that would realistically be 15 hours long to just 30 seconds with the audience still knowing exactly what is happening and not being confused by the cut.
