Editing Non-linear editing (section)

== Basic techniques ==
A non-linear editing approach may be used when all assets are available as files on [[video server]]s, or on local [[solid-state drive]]s or [[hard disk]]s, rather than recordings on reels or tapes. While linear editing is tied to the need to sequentially view film or hear tape, non-linear editing enables direct access to any [[video frame]] in a digital [[digital video|video clip]], without having to play or [[Scrubbing (audio)|scrub/shuttle]] through adjacent [[footage]] to reach it, as is necessary with [[video tape]] linear editing systems.

When ingesting audio or video feeds, [[metadata]] is attached to the clip. That metadata can be attached automatically ([[timecode]], localization, take number, name of the clip) or manually (players names, characters, in sports). It is then possible to access any frame by entering directly the timecode or the descriptive metadata. An editor can, for example, at the end of the day in the [[Olympic Games]], easily retrieve all the clips related to the players who received a gold medal.

The non-linear editing method is similar in concept to the [[Cut, copy, and paste|cut and paste]] techniques used in [[information technology]] (IT). However, with the use of non-linear editing systems, the destructive act of cutting of film negatives is eliminated. 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.<ref name=":0">{{cite book|author=Evans, Russell|title=Practical DV Filmmaking|publisher=Focal Press|date=2005|isbn=0-240-80738-3|page=14}}</ref>
