What are film Editing techniques?

Film editing is part of the creative post production process of filmmaking. The term film editing is derived from the traditional process of working with film, but now it increasingly involves the use of digital technology. The film editor works with the raw footage, selecting shots and combining them into sequences to create a finished motion picture. Film editing is described as an art or skill, the only art that is unique to cinema, separating filmmaking from other art forms that preceded it, 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 sequence. The job of an editor isn’t simply to mechanically put pieces of a film together, cut off film slates, or edit dialogue scenes. A film editor must creatively work with the layers of images, story, dialogue, music, pacing, as well as the actors' performances to effectively "re-imagine" and even rewrite the film to craft a cohesive whole. Editors usually play a dynamic role in the making of a film.

With the advent of digital editing, film editors and their assistants have become responsible for many areas of filmmaking that used to be the responsibility of others. Film editing is an art that can be used in diverse ways. It can create sensually provocative montages; become a laboratory for experimental cinema; bring out the emotional truth in an actor's performance; create a point of view on otherwise obtuse events; guide the telling and pace of a story; create an illusion of danger where there is none; give emphasis to things that would not have otherwise been noted; and even create a vital subconscious emotional connection to the viewer, among many other possibilities.
