Editing Video (section)

==Formats{{anchor|Video formats}}==
Different layers of video transmission and storage each provide their own set of formats to choose from.

For transmission, there is a physical connector and signal protocol (see [[List of video connectors]]).  A given physical link can carry certain [[#Display standards|display standards]] that specify a particular refresh rate, [[display resolution]], and [[color space]].

Many analog and digital [[recording format]]s are in use, and [[digital video]] clips can also be stored on a [[computer file system]] as files, which have their own formats. In addition to the physical format used by the [[data storage device]] or transmission medium, the stream of ones and zeros that is sent must be in a particular digital [[video coding format]], for which a number is available.

===Analog video===
Analog video is a video signal represented by one or more [[analog signal]]s. Analog color video signals include [[Luma (video)|luminance]] (Y) and [[chrominance]] (C). When combined into one channel, as is the case among others with [[NTSC]], [[PAL]], and [[SECAM]], it is called [[composite video]]. Analog video may be carried in separate channels, as in two-channel [[S-Video]] (YC) and multi-channel [[component video]] formats.

Analog video is used in both consumer and professional [[television production]] applications.

===Digital video===
[[Digital video]] signal formats have been adopted, including [[serial digital interface]] (SDI), [[Digital Visual Interface]] (DVI), [[High-Definition Multimedia Interface]] (HDMI) and [[DisplayPort]] Interface.
