 A non-linear editing approach may be used when all assets are available as files on video servers or hard disks, 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 video clip, without having to play or scrub/shuttle through adjacent footage to reach it, as is necessary with video tape linear editing systems.When ingesting audio or video feeds, metadata are attached to the clip.
