Audio Video Interleave, known by its acronym AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI files can contain both audio and video data in a standard container that allows synchronous audio-with-video playback. Like DVDs, AVI files support multiple streaming audio and video, although these features are seldom used.

RMVB is a variable bitrate extension of the RealMedia multimedia container format.
As opposed to the RealMedia container, which holds streaming media encoded at a constant bit rate, RMVB is normally used for multimedia content stored locally.
RMVB files are usually much smaller in size than MPEG4-part2 formats, such as DivX and XviD.

.mp4 is the filename extension for the multimedia container format standard MPEG-4 Part 14. This format is often referred to simply as MP4.
MP4 is similar to the MOV format, but specifies support for IOD and some other MPEG features.
MP4 files may contain any number of digital audio, digital video, and subtitle streams. MP4 allows streaming over the Internet.
Audio-only MP4 files generally have a .m4a extension; MP4 files with audio and video generally use the .mp4 and .m4v extensions.

3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones.
3GP is a simplified version of the MPEG-4 Part 14 (MP4) container format, designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. It stores video streams as MPEG-4 or H.263 or H.264, and audio streams as AMR-NB or AAC-LC. A 3GP file is always big-endian, storing and transferring the most significant bytes first. It also contains descriptions of image sizes and bitrate.
The largest mobile phone manufacturers are Nokia, Samsung, Motorola, Sony Ericsson and LG.

How to convert mpg to mp3

How to convert mpg to mp3? See the list of converters mpg2mp3.

.mpg is one of file extension for MPEG-1 files.
MPEG-1 is a group of Audio and Video coding and compression standards agreed upon by Moving Picture Experts Group (MPEG).
MPEG1 includes compression codecs for non-interlaced video signals and
for perceptual coding of audio signals.
The standard defines 3 layers, or levels of complexity, of MPEG audio coding:
- MPEG-1 Part 3 Layer 1, or MP1;
- MPEG-1 Part 3 Layer 2, or MP2;
- MPEG-1 Part 3 Layer 3, or MP3.
While MPEG1 applications are often low resolution and low bitrate, this standard allows resolution less than 4095×4095.
Now MPEG1 is the most compatible format in the MPEG family. It is used in almost all computers and VCD/DVD players.

MP3, or MPEG-1 Audio Layer 3 is a digital audio encoding, lossy compression format, and algorithm, designed to reduce the amount of data required for representing audio, but to most listeners sound like original uncompressed audio.
MP3 is an audio-specific compression format which provides representation of pulse-code modulation-encoded audio in less space than straightforward methods. It uses psychoacoustic models to discard components less audible to human hearing, and records the remaining information in an efficient manner. Similar principles are used by JPEG, a lossy image compression format.
MP3 has considerably superseded MP2 for PC and Internet applications.
Each MP3 file is made up of multiple MP3 frames which consist of the MP3 header and the MP3 data. These frames are independent items: it is possible to cut them from a file and an MP3 player would be able to play it.

How to convert flv to wmv

How to convert flv to wmv? See the list of converters flv2wmv.

FLV is a proprietary file format used to deliver video over the Internet using Adobe Flash Player version 6, 7, 8, or 9. FLV content may also be embedded within SWF files.
Flash Video is viewable on most operating systems, via the Adobe Flash Player and web browser plugin, or one of several third-party programs such as Media Player Classic, MPlayer, or VLC media player.
Usually FLV files contain video bit streams which are a variant of the H.263 video standard.
The FLV file format supports two versions of a so called ’screenshare’ codec which is an encoding format designed for screencasts. Both these formats are bitmap tile based, can be lossy by reducing color depths and are compressed using zlib.
Audio in FLV files is usually encoded as MP3.

WMV (Windows Media Video) is a name for the set of video codec technologies developed by Microsoft.
WMV files use ASF container format. These files can be played by MPlayer or Windows Media Player.
The .wmv file extension usually describes ASF files using Windows Media Video codecs. The audio codec used with WMV is normally a version of WMA.
Besides ASF, WMV can be put into the AVI or MKV container formats as well.
Originally the WMV codec was designed for Internet streaming applications. Two other codecs – WMV Screen and WMV Image – are a screencast codec and a video slideshow codec respectively.

How to convert doc to swf

How to convert doc to swf? See the list of converters doc2swf.

.doc is a file extension for word processing documents.
DOC files often contain more text formatting information (as well as scripts and undo information) than files using other document file formats like RTF and HTML, but are less widely compatible.

DOC is the standard document format of MS Word.

SWF (Small Web Format) is a proprietary vector graphics file format produced by the Flash software.
SWF files can contain animations or applets of varying degrees of interactivity and function. SWF is also used for creating animated display graphics and menus for DVD movies, and TV commercials.
The Flash program produces SWF files as a compressed and uneditable final product, whereas it uses the FLA format for its editable working files.
SWF is now the main format to display animated vector graphics on the web.

How to convert DivX to avi

How to convert DivX to avi? Please see the list of converters divx2avi.

DivX is a brand name of products created by DivX, Inc. including the DivX Codec which is popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression where quality is balanced against file size for utility. It is one of several codecs commonly associated with ripping, where audio and video multimedia are transferred to a hard disk and transcoded.
An open source version of the codec was released by DivX in 2001, and this version served as the basis for the open source Xvid codec.

MPEG is a working group of ISO/IEC creating standards for digital video and audio compression. MPEG file formats are used to encode audio, video, text, and graphical data within a single, synchronized data stream.
MPEG has standardized the following compression formats and ancillary standards:
- MPEG-1: Initial video and audio compression standard;
- MPEG-2: Transport, video and audio standards for broadcast-quality television;
- MPEG-3: Originally designed for HDTV, but abandoned as MPEG-2 was sufficient for HDTV;
- MPEG-4: Expands MPEG-1 to support video/audio “objects”, 3D content, low bitrate encoding and support for Digital Rights Management.
