Editing Inter frame (section)

==Additional information==
Although the use of the term "frame" is common in informal usage, in many cases (such as in [[international standard]]s for video coding by [[MPEG]] and [[VCEG]]) a more general concept is applied by using the word "picture" rather than "frame", where a picture can either be a complete frame or a single [[interlaced]] field.

[[Video]] [[codecs]] such as [[MPEG-2]], [[H.264]] or [[Ogg]] [[Theora]] reduce the amount of data in a stream by following key frames with one or more inter frames.  These frames can typically be encoded using a lower [[bit rate]] than is needed for key frames because much of the image is ordinarily similar, so only the changing parts need to be coded.
