	File format - Encyclopedia.WorldSearch (Site not responding. Last check: 2007-11-07)
		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.
		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.
		Since files are seen by programs as streams of data, a method is required to determine the format of a particular file within the filesystem — an example of metadata.

	Video - Wikipedia, the free encyclopedia
		Video (from Latin, "I see") is the technology of processing electronic signals for representing moving pictures.
		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).
		In the UK, the term video is often used informally to refer to both video recorders and video cassettes; the meaning is normally clear from the context.

	Container format - Wikipedia, the free encyclopedia
		A container format is a computer file format that can contain various types of data, compressed in a manner of standardized codecs.
		The container file is used to be able to identify and interleave the different data types.
		Older formats such as AVI do not support new codec features like B-frames, VBR audio, VFR natively, although the format may be "hacked" to add support, creating compatibility problems.

	Video File Format Comparison
		When dealing with video files there are several factors that need to be considered, like bit depth, frame size and frame rate as well as compression and codecs used.
		Where file size or data rate are more important than the quality of motion, such as for Internet delivery, specifying a lower frame rate may help compression by reducing the amount of data to compress.
		This is a general purpose format for exchanging multimedia data types that was defined by Microsoft and IBM during their long forgotten alliance.

		The format can also be created on a PC, but the extension of the file name will then change to LBM or to CE (Depending on the application).
		CE file format is the name used for IFF files that were created on an MS-DOS platform using the Digital Vision's Computer Eyes video scanner board.
		Files saved to the CUT format from various applications will appear as two color files if they were recognized that way or as 256-color files if they had more than two colors initially.

	Digital Video File Formats (Site not responding. Last check: 2007-11-07)
		A video frame is made up of two fields that correspond to the interlaced method of painting the pixels twice, 1/60 of second apart, on a television set.
		These formats are generally used for the storage and viewing of video by and on computer systems (with the exception of the MPEG formats).
		It's normal format is a frame size of 352 x 240 and a constant bit stream of around on megabit per second, a rate well within that of any CD player.

	Crutchfield Advisor - Digital A/V File Formats - The Basics
		A file format is simply a specified way of arranging a given type of information into bytes.
		If a codec causes a degradation of sound or picture quality in the process of squeezing and then unpacking a file, that codec said to be "lossy." That is, certain portions of the data which are judged to be less essential are removed, and can't be restored upon playback.
		There are a few file formats, like RealMedia, that are used almost exclusively in streaming applications.

	Video file formats for web
		Conventional video, such as those used current TV and camcorders, are encoded in analog signals.

	Video Formats and CODECs
		Unlike images, which are almost invariably GIF or JPG format (especially when aimed at the Web), video file formats are not quite so universal.
		In addition, since uncompressed video files are quite huge, some compression is almost invariably required.
		However, since the format is proprietary, you must make sure the computer on which you run the video has the player, available from Apple’s website at http://www.apple.com/quicktime/ If you intend to deliver the video via the Web, be sure to supply a link to the Quicktime site on your page.

		In some formats, a single frame is independent of any other (such as those used in computer video formats), so the sequence is only one frame.
		When a device sends a frame, the video format usually specifies that devices sends each line independently from any others and that all lines are sent in top-to-bottom order.
		An interlaced video frame distinguishes itself from the progressive scan frame where the entire frame sends as a single intact entity.

	Factsheet 24: How can I put sound and video into my web pages?
		The MP3 file format has become extremely popular in recent years for Internet-based audio file distribution, because it allows near-CD quality sound to be compressed into a reasonably small file size.
		Remember that your audio or video file must be published in the same way as any other web file (Factsheet 10).
		Before the advent of streaming, audio and video files needed to be downloaded in their entirety before they could be played.

		Dozens more are out there, but these seem to be the most popular, or those "on the cutting edge." Some formats would be worth looking at due to their superior compression, but only appeal to a small sector because they are native, proprietary formats.

	Media Advice: Converting Video Formats
		Sourcing from a file with a.mpg file name extension requires a compatible DVD decoder (sometimes known as an MPEG-2 decoder) on the encoding computer.
		Although the WMV format works well for streaming audio and video over a network, it's not as well-suited for editing as the format used for AVI files.
		Simply connect the audio and video analog outputs of a DVD player to a video capture card on your computer, and then use Windows Media Encoder to encode the video to a file.
