Film editing is part of the post-production process of filmmaking. It involves the selection and combining of shots, connecting the resulting sequences, and ultimately creating a finished motion picture. It is an art of storytelling. Film editing is the only art that is unique to cinema, separating film-making from other art forms that preceded it (such as photography, theater, dance, writing, and directing), although there are close parallels to the editing process in other art forms like poetry or novel writing. Film editing is often referred to as the "invisible art" because when it is well-practiced, the viewer can become so engaged that he or she is not even aware of the editor's work. On its most fundamental level, film editing is the art, technique, and practice of assembling shots into a coherent whole. A film editor is a person who practices film editing by assembling the footage. However, the job of an editor isn t simply to mechanically put pieces of a film together, cut off film slates, or edit dialogue scenes.
