Digital File Descriptions

3GPP Logo3GPP 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.


AVI LogoAVI means Audio Video Interleave, 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 file container that allows synchronous audio-with-video playback.  The AVI file type is primarily associated with 'Audio Video Interleave File'.

  • Uncompressed AVI: AVI files can be created with no compression, resulting in extremely large file sizes, but with no loss of quality from the input video to the saved file.
  • Compressed AVI: AVI video files can be compressed with codecs like DivX and XviD.


DivX LogoDivX is a video format created by DivX, Inc. DivX became quite popular due to the ability to compress videos to almost 15% of the original size (i.e. 2Gb down to 700Mb).  That means that a full film can be fitted into a CD.  What is important, the .divx files retain much of the original quality of the DVD, sometimes the result is even indistinguishable from the source.  Small size and high quality has made DivX the most popular format of online video and there are a lot of hardware DVD players that support DivX now.


Divx Plus HD LogoDivX Plus HD files uses the H.264 video codec in an MKV container with AAC audio.  Okay, great… but why?  Well, the compression capability of H.264 video combined with the flexibility of the MKV container and the 5.1 channel surround sound of AAC audio make it the preferred formats for HD video on the Internet.


Flash Video LogoFlash video is a relative newcomer to the digital video scene.  Up until version 6, Flash did not handle full-motion video well enough to be useful.  As of version 7, true streaming video is supported by Flash and anyone with the latest player can see Flash video clips.  The Flash player is very common — around 95% of browsers have it installed but in order to manipulate and edit the Flash Video I give you, you'll need Macromedia Flash and that's a fairly expensive piece of software!


MOV Video LogoMOV video file is a common multimedia format often used for saving movies and other video files, using a proprietary compression algorithm developed by Apple Computer, compatible with both Macintosh and Windows platforms.  The International Organization for Standardization approved the QuickTime (.mov) file format as the basis of the MPEG-4 file format.  The MPEG-4 file format specification was created on the basis of the QuickTime format specification.


MPEG1 LogoMPEG-1 - the Moving Picture Experts Group (MPEG) is a working group of experts that was formed by ISO and IEC to set standards for audio and video compression and transmission.  MPEG1 is a standard for lossy compression of video and audio.  It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible.


MPEG2 LogoMPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial, cable, and direct broadcast satellite TV systems.  It also specifies the format of movies and other programs that are distributed on DVD and similar discs.  As such, TV stations, TV receivers, DVD players, and other equipment are often designed to this standard.  MPEG2 succeeded the MPEG1 to address some of the older standard's weaknesses such as quality.


MP4 LogoMPEG-4 is one of the latest (audio and video) compression method standardized by MPEG group, designed especially for low-bandwidth (less than 1.5 MBit/sec bitrate) video/audio encoding purposes.  Probably the best-known MPEG-4 video encoders are called DivX and XviD, which both are nowadays fully standard-compliant MPEG-4 encoders.


Real Media LogoReal Media Video is supported on many platforms, including Windows, Mac, Linux, Solaris, and several mobile phones.  RealVideo is usually paired with RealAudio and packaged in a RealMedia (.rm) container.  RealMedia is suitable for use as a streaming media format, that is one which is viewed while it is being sent over the network.  Streaming video can be used to watch live television, since it does not require downloading the entire video in advance.


MT2S LogoMTS and M2TS are both file extensions for the high definition digital video camera recorder format, AVCHD (Advanced Video Codec High Definition).  AVCHD was jointly established by Sony Corporation and Panasonic Corporation in 2006 for use in their digital tapeless camcorders using the MPEG-4 AVC/H.264 video codec and audio in Dolby AC-3.  In order to view and/or edit this file type both the MTS and the M2TS files can be played on Cyber Link Power DVD, Cyber Link Power Director, Sony Picture Motion Browser or Sony Vegas Movie Studio Platinum.


Windows Media LogoWindows Media (WMV) is a compressed video compression format for several proprietary codecs developed by Microsoft.  The original video format, known as WMV, was originally designed for internet streaming applications.  Microsoft claims that WMV 9 provides a compression ratio that is 2x better than MPEG-4, and 3x better than MPEG-2 but, one test report showed that WMV 9 had worse compression efficiency than WMV 8, and many 3rd party WMV compilers have had worse performance than Windows Movie Maker.
