Audio Video Interleave (AVI)
Both of AVI and WMV were developed by Microsoft in the 1990's. AVI is the Audio Video Interleave, a multimedia container format (.avi). AVI files can contain both audio and video data in a file container that allows synchronous audio with video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used.
Uncompressed AVI files are huge. AVI codecs (COmpressor - DECompressor) greatly reduce file sizes while maintaining optimum quality. AVI's popularity and extensibility depend on the fact that you can freely select different video and audio codecs, these compression methods include: CINEPAK, Microsoft MPEG4 Video, Microsoft Video 1, MJPEG (Motion JPEG), DivX and XviD.
Compression reduces the file size, but reduces the quality by an amount that varies depend the settings chosen. While different codecs provide different compression ratios, a lot depends on the specific settings that you select when creating your files. Windows Media Video is one good choice for distributing to a wide people, since it has the widest compatibility.
Windows Media Video (WMV)
Windows Media Video (WMV) is another compressed video file format for several proprietary codecs developed by Microsoft. The original codec, known as WMV, it is very popular also. Usage of the term WMV often refers to this codec only. Its main competitors are MPEG-4 AVC, Real Video, DivX, and Xvid. This codec also supports professional-quality downloadable video with two-pass and variable bit rate (VBR) encoding.
Microsoft claims that WMV 9 provides a compression ratio that is two times better than MPEG-4, and three times better than MPEG-2; Microsoft also claims that WMV 9 is 15-50% better than WMV 8 in terms of compression efficiency. Transport independence also enables the delivery of Windows Media Video 9 Advanced Profile over systems that are not Windows Media-based, such as standards-based broadcast infrastructures (through native MPEG-2 transport streams), wireless infrastructures (using real-time transfer protocol [RTP]), or even DVDs.
