Editing Digital video (section)

==Technical overview==
Standard [[film stock]]s typically record at 24 frames per second. For video, there are two frame rate standards: [[NTSC]], at 30/1.001 (about 29.97) frames per second (about 59.94 fields per second), and [[PAL]], 25 frames per second (50 fields per second). Digital video cameras come in two different image capture formats: interlaced and [[progressive scan]]. Interlaced cameras record the image in alternating sets of lines: the odd-numbered lines are scanned, and then the even-numbered lines are scanned, then the odd-numbered lines are scanned again, and so on.

One set of odd or even lines is referred to as a ''field'', and a consecutive pairing of two fields of opposite parity is called a ''frame''. Progressive scan cameras record all lines in each frame as a single unit. Thus, interlaced video captures the scene motion twice as often as progressive video does for the same frame rate. Progressive scan generally produces a slightly sharper image, however, motion may not be as smooth as interlaced video.

Digital video can be copied with no generation loss; which degrades quality in analog systems. However, a change in parameters like frame size, or a change of the digital format can decrease the quality of the video due to [[image scaling]] and [[transcoding]] losses. Digital video can be manipulated and edited on [[non-linear editing]] systems.

Digital video has a significantly lower cost than 35&nbsp;mm film. In comparison to the high cost of [[film stock]], the digital media used for digital video recording, such as [[flash memory]] or [[hard disk drive]] is very inexpensive. Digital video also allows footage to be viewed on location without the expensive and time-consuming chemical processing required by film. Network transfer of digital video makes physical deliveries of tapes and film reels unnecessary.

Digital television (including higher quality [[HDTV]]) was introduced in most developed countries in early 2000s. Today, digital video is used in modern [[mobile phone]]s and [[video conferencing]] systems. Digital video is used for [[Internet]] distribution of media, including [[streaming video]] and [[peer-to-peer]] movie distribution.

Many types of video compression exist for serving digital video over the internet and on optical disks. The file sizes of digital video used for professional editing are generally not practical for these purposes, and the video requires further compression with codecs to be used for recreational purposes.

{{As of|2017}}, the highest [[image resolution]] demonstrated for digital video generation is 132.7 [[megapixel]]s (15360 x 8640 pixels). The highest speed is attained in industrial and scientific [[high-speed camera]]s that are capable of filming 1024x1024 video at up to 1 million frames per second for brief periods of recording.
