Explanation:

traditional film production, multiple cameras are often used to shoot each scene. (See the camera positions A, B, and C in the figure on the right). Actors play the same scene a number of times until the director is satisfied with their performance and also until each scene is recorded using all the camera positions that may be needed.

In the editing phase, selected shots are assembled into a scene, scenes into the final piece. The editing is done in a such way that the story is told most effectively. A large amount of what’s recorded will not be included in the final edited work, not even the deleted scenes on DVDs!
