Editing Video editing software (section)

==Components==

===Timeline===

NLE software is typically based on a [[timeline]] interface where sections moving image video recordings, known as clips, are laid out in sequence and played back. The NLE offers a range of tools for trimming, splicing, cutting, and arranging clips across the timeline.

Another kind of clip is a text clip, used to add text to a video, such as [[title screens]] or [[movie credits]].<ref>{{Cite web|url=https://userbase.kde.org/Kdenlive/Manual/Titles|title=Titles, Kdenlive Manual}}</ref> Audio clips can additionally be mixed together, such as mixing a [[soundtrack]] with multiple [[sound effects]].

Typically, the timeline is divided into multiple rows on the y-axis for different clips playing simultaneously, whereas the x-axis represents the run time of the video.<ref>{{Cite web|url=https://www.techsmith.com/blog/edit-videos-timeline/|title=How to Edit Videos in the Timeline, The TechSmith Blog}}</ref>

Effects such as [[film transition|transitions]] can be performed on each clip, such as a [[Dissolve (filmmaking)|crossfade]] effect going from one scene to another.

===Exporting===

Since video editors represent a project with a [[file format]] specific to the program, one needs to export the video file in order to publish it.

Once a project is complete, the editor can then [[Import and export of data|export]] to movies in a variety of formats in a context that may range from broadcast tape formats to [[Video coding format|compressed video file]]s for web publishing (such as on an [[online video platform]] or [[personal website]]), [[optical media]], or saved to mobile devices.

To facilitate editing, source video typically has a higher resolution than the desired output. Therefore, higher resolution video needs to be [[image scaling|downscaled]] during exporting, or after exporting in a process known as [[transcoding#Re-encoding/recoding|transsizing]].

===Visual effects===

As digital video editing advanced, visual effects became possible, and is part of the standard toolkit, usually found in prosumer and professional grade software.

A common ability is to do [[compositing]] techniques such as [[chroma key]]ing or [[luma key]]ing, among others, which allow different objects to look as if they are in the same scene.<ref>{{Cite web|url=https://www.adobe.com/creativecloud/tools/green-screen-software.html|title=Green screen software - Chroma key video editing tools, Adobe Software}}</ref>

A different kind of visual effects is [[motion capture]]. Software such as [[Blender (software)|Blender]] can perform motion capture to make animated objects follow an actor's movements.

===Additional features===

Most professional video editors are able to do [[color grading]], which is to manipulate visual attributes of a video such as contrast to enhance output, and improve emotional impact.<ref>{{Cite web|url=https://www.videomaker.com/how-to/editing/what-is-color-grading/|title=What is color grading and why is it important? - Videomaker}}</ref>

Some video editors such as [[iMovie]] include [[stock footage]] available for use.
