Topic: Video format



  
 Video coding - Wikipedia, the free encyclopedia
Video coding is the field in computer science that deals with finding efficient coding formats for video that is digital (DV).
Modern video coding standards even include other multimedia data such as synthetic computer graphics, text and meta information for searching/browsing and digital rights management.
A computer program that encodes and decodes video data is called video codec.

 Video - Wikipedia, the free encyclopedia
Video can be created with mechanical cameras (capture on celluloid film), video cameras (capture electric signal in PAL or NTSC formats) or digital cameras (commonly capture in digital MPEG-4 or DV formats).
Very common way to reduce number of bits per pixel in digital video is chroma subsampling (for example 4:4:4, 4:2:2, 4:2:0).
Format of this type of video was fixed in MPEG-4 Part 16 Animation Framework eXtension (AFX).

 Streaming video - definition of Streaming video in Encyclopedia
It does not try to reassemble as many bits associated with video content as binary computer file formats do.
A streaming format is usually defined at the bit level (comprising a bitstream), so that streams do not have to be aligned to even byte boundaries, whereas file formats for media usually require even alignment.
New cameras can be connected to a computer through USB.

 File format - Encyclopedia.WorldSearch
Many file formats, including some of the most well-known file formats, have a published specification document (often with a reference implementation) that describes exactly how the data is to be encoded, and which can be used to determine whether or not a particular program treats a particular file format correctly.
Other file formats, however, are designed for storage of several different types of data: the GIF format supports storage of both still images and simple animations, and the AVI format can act as a container for many different types of multimedia.
A file format is a particular way to encode information for storage in a computer file.

 CISD: Digital Media File Type Comparison
Formats may be proprietary or nonproprietary, native to one particular software program or useable in a number of programs, and each has its own characteristics, making one "better" than another for its desired use.
There are also numerous formats that are native to only one particular program, such as Adobe Photoshop's PSD.
There are hundreds of file formats for representing media online or in print, for medical imaging, homeland defense, and countless other applications.
