Film editing is part of the creative post-production process of filmmaking.
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, 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 it’s most fundamental level, film editing is the art, technique, and practice of assembling shots into a coherent sequence.
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.
