David Wark Griffith was an American film director. Considered one of the most influential figures in the history of the motion picture, he pioneered many aspects of film editing and expanded the art of the narrative film.

Film editing is both a creative and a technical part of the post-production process of filmmaking. The term is derived from the traditional process of working with film which increasingly involves the use of digital technology. When putting together some sort of video composition, typically, you would need a collection of shots and footages that vary from one another. The act of adjusting the shots you have already taken, and turning them into something new is known as film editing.
