Today, I want to tell you about kinds of Videos format. It just for knowledge. Here it is :


3ivx: not a file format, but only a codec (like Divx, WMV and Xvid) developed by 3ivx Technologies (www.3ivx.com). Core technology is optimized for a wide range of processor architectures, including the accompanying platforms. 3ivx allows for the preparation of the data stream and MP4 MPEG-4 and can also be used to make steam AAC audio. By using the 3ivx can store more than two hours of DVD-quality movies into a single CD, or to stream DVD-quality video quality via cable modem or DSL modem. To open a file 3ivx, required plug-in for Quicktime, for video for windows and for Directshow Decoder or the 3ivx.

ASF (Advanced Streaming Format / Advanced Systems Format) is a format developed by Microsoft that is used for audio digital video. Designed for streaming and form part of the Windows Media framework. ASF can use a variety of codecs. But in practice that is used is WMV or WMA codecs also from Microsoft.
AVI (Audio Video Interleaved): introduced by Microsoft in 1992 as part of Video for Windows technology hers. AVI files store audio and video data on the structure of the interleaved. This file is just a container-video and audio data can be compressed using different codecs. The quality and capacity depending on the particular codec and the codec used is MPEG, DivX or WMV.
Divx: the codec, not the file format. Divx first edition (3.11 and earlier) is a hacked version of Microsoft's MPEG4 codecvideo.Rota Jeroma developer Divx, Divx Networks set up and create Divx 4, the latest version of codecs to avoid copyright issues with Microsoft. Divx at the time of version 5.2.1 is an MPEG-4 codec layer 2. Known for its high compression rate, so it is allowed to use codectersebut to duplicate a DVD movie. A DVD movie is generally a size of 5 GB to 6 GB, and Divx capable of compressing up to 700 MB, with a very minimal loss of quality.Thus the film can be accommodated in a CD. Some devices use DVD ripping codecDivx. To play Divx files, plug-ins required for the Divx player software. Version includes a free Divx player is available at www.divx.com and this includes plug-ins for video editing software.

MJPEG (Motion JPEG): This is a video codec that compresses each frame as a separate JPEG image. Its quality depends on the movement in the footage. In contrast to MPEG video, the quality decreases when there is a lot of movement in the footage.Disadvantages of this codec is a large file sizes.
MPEG: is a compression format standardized by the Moving Picture Experts Group (MPEG), which is formed by 350 companies and organizations. The standards are: MPEG 1 is the first standard for audio and video compression. is the standard VideoCD encoded with a maximum resolution of only 352 x 288 pixel resolution, bit-rate can not be changed and the image quality is less baik.Ini also includes MP3 audio format. MPEG 2 is a series of standard transports, audio and video for television broadcast quality. MPEG 3 was developed for high-definiton television (HDTV), but later abandoned because it was considered adequate MPEG 2. MPEG 4 is the development of MPEG 1 support the Digital Rights Management (DRM) and low bit-rate encoding, and uses a video codec called H.264 which is considered more efficient. MPEG 7 is a formal system for describing multimedia content. MPEG 21 is the future standard for multimedia. MPEG codecs use lossy audio data compression on the video.Part motion video on a standard MPEG-1 obtained from the standard Joint Picture Experts Group (JPEG) lossy compression for still images (photos) MPEG-1 is used in VideoCD format. Output quality and bit-rate is smaller than a VCR. MPEG-2 the same as MPEG-1, but also provides support for interlaced video (like on TV) and also supports Transport Stream is designed to transfer digital video and audio on the media and used for broadcasting. Standard MPEG-2 level today has become the latest standard for HDTV transmission. Currently used for SVCD, DVD with a bit rate that can be changed and has exceptional image quality. DV video is a special subformat of MPEG-2 with a fixed bit rate. This format is suitable for video editing. MPEG-4 based on MPEG-1 and MPEG-2, but there are additional features such as VRML support for 3D rendering, object-oriented composite files (including audio, video and virtual reality modeling), support for DRM and various kinds of interactivity. Container for MPEG-4 content is MP4
OGM (Ogg Media File): is a container format for audio, video and subtitle. As AVI, this format also supports multiple audio tracks, even with different formats (like MP3 and WAV). OGM also allows the integration of audio Ogg Vorbis. Video codecs are often used in OGM files are Xvid. To open the OGM file in windows needed a software package called Ogg Vorbis Direct Filter and can be obtained at www.tobias.everwicked.com
Quicktime: is the multimedia technology as well as file format developed by Apple Computer and diprkenalkan first time in 1991. Quicktime is a multimedia container file that is formed on one or more tracks like audio, video, text or digital effects. Each track contains track media, be it a media stream that has been encoded or pointers to external files. codec used to compress and decompress data in Quicktime including MP3, JPEG, DivX, Cinepak, Sorensen and even MPEG-2 and MPEG-4. By sebeb it, quicktime more suitable for Internet applications compared to AVI
RealVideo and RealMedia: is a video codec developed by RealNetworks in 1997. In contrast to other video codecs, RealVideo has been optimized for streaming video over an IP network. Using PNA Real Time Streaming Protocol or Protocol.Usually paired with RealAudio is packaged in a RealMedia.RealNetworks also provides the player called RealPlayer for audio and video.
WMV (Windows Media Video): is a part of the system made by Microsoft Windows Media. Is a codec for movies and transform mengencode slide show that contains the video into a compressed bitmap format. WMV is actually a proprietary version of MPEG-4. Video Stream is often combined with Audio Stream in WMA format, with WMV video is packed into containers AVI or ASF.
Matroska is a free multimedia formats (open-source format). This format, with the file extension from '. Mkv ', based on EBML (Extensible Binary Meta Language), which allows changes to be done with ease if necessary, without violating supports long file.This is why it is said that "Matroska is designed with the future in mind". Matroska is not a video codec as is often thought to be, but a container, or an envelope that can hold many different codecs at the same time. As the name implies (egg-shaped Russian dolls contained within each other) Matroska can contain video (DivX, Xvid, RV9, etc), sound (MP3, MP2, OGG, AC3, AAC, DTS, PCM), as well as subtitles (SRT , ASS, SSA, USF, etc) in the same file. Matroska development goal is to provide a flexible and cross-platform alternative to AVI, ASF, MP4, MPG, MOV, and RM. Its main features include a quick search, high error recovery, modularly extendable, choose subtitle and audio streams, chapter entries, menus, and streamable via the internet. An example of a Matroska file is a complete video files That includes a video stream and an audio stream, as well as subtitles and a menu system. Example of a Matroska file a complete video file that includes streaming video and audio streams, as well as subtitles and menu system.
3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones. Which is used in 3G phones, but can also be played on some 2G and 4G phones.
Flash Video is a container file format used to transmit video over the Internet using Adobe Flash Player (initially produced by Macromedia) versions 6-10. Flash Video content may also be embedded within SWF files. There are two different video file format defined by Adobe Systems and are supported in Adobe Flash Player: FLV and F4V. Audio and video data within FLV files are encoded in the same way when they are in a SWF file.The latter F4V file format is based on the ISO base media file format and is supported starting with Flash Player 9 Update 3.
3G2 (3GPP2 file format) is a multimedia container format defined by 3GPP2 for CDMA2000 3G multimedia services. This is very similar to the 3GP format, but has some extensions and limitations in comparison to 3GP.
VOB (Video Object) is a container format in DVD-Video media.VOB can contain video, audio, subtitle and menu contents multiplexed together into the shape of the river. VOB is based on the MPEG program stream format, but with limitations and additional specifications on private river. MPEG program stream with the provisions of non-standard data (such as those used in the VOB files) in the form of so-called private stream. VOB files are very strict part of the standard MPEG program stream. While all of the MPEG program stream VOB files, not all of the MPEG program stream in accordance with the definition for a VOB file.
SWF (originally standing for "Small Web Format" later changed to "Shockwave Flash" by Macromedia, and then again changed back to Small Web Format when companies choose to have the phrase "Shockwave" only refers to the Director, pronounced swiff or "swoof" is partially open repository for multimedia and especially for vector graphics, originated from FutureWave Software and has come under the control of Adobe. Intended to be small enough to be published on the web, SWF files can contain animations or applets of varying degrees of interactivity and function. SWF currently functions as the dominant format for displaying "animated" vector graphics on the web, far exceeding the use of the W3C open standard SVG, which has met with problems over competing implementations. It may also be used for programs, usually a game, using Actionscript.
