 a non-linear editing system (nle) is a video (nlve) or audio editing (nlae) digital audio workstation (daw) system that performs non-destructive editing on source material. the name is in contrast to 20th century methods of linear video editing and film editing. videowisconsinstudio|thumb|right|alt=an example of a video editing studio|example of a non-linear video editing studio == linear and non-linear editing == non-linear editing is the most natural approach when all assets are available as files on video servers or hard disks, rather than recordings on reels or tapesâwhile linear editing is tied to the need to sequentially view film or hear tape. === metadata === when ingesting audio or video feeds, metadata are attached to the clip. those metadata can be attached automatically (timecode, localization, take number, name of the clip) or manually (players names, characters, in sports: red card, goal...). === direct access === non-linear editing 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 editing systems. it is now 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, ask to retrieve all the clips related to the players who received a gold medal. === basic techniques === the nle method is similar in concept to the "cut and paste" techniques used in film editing or in 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.russell evans, practical dv filmmaking, focal press, 2005 isbn 0-240-80738-3, isbn 978-0-240-80738-6 page 14 == broadcast workflows and advantages == video and audio data are first captured to video servers, other hard disk-based systems, or other digital storage devices. the data are either direct to disk recording or are imported from another source (transcoding, digitizing, transfer). once imported, the source material can be edited on a computer using application software, any of a wide range of video editing software. for a comprehensive list of available software, see list of video editing software, whereas comparison of video editing software gives more detail of features and functionality. in non-linear editing, the original source files are not lost or modified during editing. t
