AVI, full name is Audio Video Interleave. It is technically stand known as a multimedia container format and was introduced by Microsoft in 1992. Being a multimedia container format, AVI files can include both video and audio, allowing synchronous playback.Most AVI files also use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called "AVI 2.0". Files of this type have a .avi file extension name.
AVI files can be found online as movies, music videos, TV shows, streaming video and can even be downloaded as a full length motion picture.

WMV, full name is Windows Media Video. It was developed by Microsoft specifically for streaming, however, it can also be saved to a hard drive or disc media for playback with Windows Media Player and other types of players such as Winamp, DivX and VLC player, or edit in windows movie maker. A WMV file is in most circumstances encapsulated in the Advanced Systems Format (ASF) container format. The file extension name .WMV typically describes ASF files that use Windows Media Video codecs. The audio codec used in conjunction with Windows Media Video is typically some version of Windows Media Audio, or in rarer cases, the deprecated Sipro ACELP.net audio codec. Microsoft recommends that ASF files containing non-Windows Media codecs use the generic .ASF file extension name. Although WMV is generally packed into the ASF container format, it can also be put into the AVI or Matroska container format. The resulting files claim the .AVI, or .MKV file extensions, respectively. WMV can be stored in an AVI file when using the WMV 9 Video Compression Manager (VCM) codec implementation. The current version of WMV is WMV9 which includes the feature of a high compression rate in order to fit large videos into a small amount of storage space, making it a great format for transferring over the internet.
