Non-linear editing for films and television post-production is a modern video editing method which enables direct access to any video frame in a digital video clip, without needing to play or scrub/shuttle through adjacent footage to reach it, as was necessary with historical video tape linear video editing systems. It is the most natural approach when all assets are available as files on hard disks rather than recordings on reels or tapes, while linear editing is related to the need to sequentially view a film or read a tape to edit it. On the other hand, the NLE method is similar in concept to the "cut and paste" technique used in film editing. However, with the appropriation of non-linear editing systems, the destructive act of cutting of film negatives is eliminated. Non-linear, non-destructive editing methods began to appear with the introduction of digital video technology. It can also be viewed as the audio/video equivalent of word processing, which is why it is called desktop video editing in the consumer space.
