Common Video file Formats

1	GIF (. gif)	It is a color image file of high compression ratio that CompuServe company exits. GIF format adopts the LZW algorithm with high efficiency in lossless compression, which is mainly used for network transmission of image files. In view of the actual situation of the network transmission, the GIF image format adds the fade mode in addition to a general progressive display. In other words, in the image transmission process, the user can first see the image of the approximate outline, and then with the continuation of the transmission process and gradually see the details of the image, thus adapting to the user's viewing psychology. Most of the color animation files used on the Internet are in GIF format.
2	Flic (. fli/. FLC)	Flic is the color animation file format used by Autodesk in 2D, 3D animation software such as Autodesk Animation/animatior pro/3d Studio. which. FLI is the original 320x200 resolution-based animation file format. FLC is. Fli's further expansion, the use of more efficient data compression technology, its resolution is no longer limited to 320x200, flic files using process encoding (RLE) SUANFA and Delta algorithm for lossless data compression, with high data compression rate.
3	AVI (. AVI)	The earlier AVI was developed by Microsoft. The implication is audio video Interactive, which is to mix video and audio encoding together for storage. Avi is also the longest-lived format, has existed for more than 10 years, although the release of the revision (V2.0 in 1996), but has been significantly old state. AVI format is more restrictive, can only have a video track and an audio track (now there are non-standard plug-ins can join up to two audio tracks), you can also have some additional tracks, such as text. AVI format does not provide any control functions.
4	Quick time (. mov/. QT)	QuickTime movie is a container developed by Apple, and because of the dominance of Apple computers in the field of professional graphics, QuickTime format is basically a common format for the filmmaking industry. February 11, 1998, the International Standards Organization (IS0) endorsed the QuickTime file format as the basis for the MPEG-4 standard. QT can store a wealth of content, in addition to video, audio can also support images, text (text subtitles) and so on.
5	MPEG (. mpeg/. mpg/. DAT)	MPEG (Moving Picture Experts Group) is an international Standards Organization (IS0)-Approved media package form, supported by most machines. They are stored in a variety of ways and can be adapted to different application environments. The file container format of the MPEG-4 file is specified in Layer 1 (MUX), + (MPG), and (AVC), etc. MPEG is rich in control and can have multiple videos (i.e. angles), audio tracks, subtitles (bitmap subtitles), and more. A simplified version of MPEG 3GP is also widely used on quasi-3G phones. Sub file name: Dat (for DVD), VOB, Mpg/mpeg, 3gp/3g2 (for mobile), etc.
6	RealVideo (. rm/rmvb)	Real video or real Media (RM) files are a file container developed by RealNetworks. It usually only accommodates real video and real audio encoded media. This file has some interactivity and allows scripting to control playback. RM, especially the RMVB format with variable bitrate, is very small and very popular with network downloader.
7	WMV (wmv/asf, WMVHD)	WMV (Windows Media Video) is the generic term for a set of digital video codec formats developed by Microsoft Corporation, and the ASF (Advanced Systems format) is its encapsulation format. The ASF encapsulated WMV file has the Digital Rights protection feature.
8	Divx/xvid	DivX is a digital multimedia compression technology invented by DivXNetworks company, similar to MP3. DivX based on MPEG-4, you can compress the MPEG-2 format of multimedia files to the original 10%, but also the VHS format video format files to the original 1%. With broadband devices such as DSL or Cablemoden, it allows you to enjoy high-quality digital movies in full screen. It also allows viewing of machines on other devices (such as digital TVs, Blu-ray players, PocketPC, digital photo frames, mobile phones), which can be played smoothly as long as the video CPU is over 300MHz, 64M memory and a 8M video card. With DivX file size and better image quality, a CD-ROM can hold 120min of quality close to DVD movies.
9	Dv	DV: (digital video) is typically used to refer to a device (such as a camcorder) that captures and stores video in a digital format. There are DV type I and DV type II two AVI files DV Type I: Digital video AVI files contain raw video and audio information. DV type I files are typically smaller than the DV type II file and are compatible with most A/V devices, such as DV camcorders and Sound Recorder. DV Type II: The digital video AVI file contains the original video and audio information, and also contains a separate audio track as a copy of the DV audio. DV type II is more versatile than DV type I software because most programs that use AVI files want to use a separate audio track.
10	MKV (. MKV)	Matroska is a new multimedia package format that encapsulates a variety of different encoded videos and 16 or more different formats of audio and language subtitles into a Matroska media file. It is also one of the open source multimedia encapsulation formats. Matroska also provides very good interactivity, and is more convenient and powerful than MPEG.
11	OGG (. OGG)	Ogg Media is a fully open multimedia system program, OGM (Ogg media File) is its container format. OGM can support multiple tracks such as multi-video, audio, subtitles (text subtitles), and more.
12	MOD	The MoD format is the name of the storage format used by JVC to produce the hard disk camcorder.
