The data in it is encoded by various codecs such as DivX and XviD. There is a variety of software that support these files. For instance- Microsoft Movies & TV, Windows Media Player and Apple QuickTime player; etc. Due to its low compression ability, it is widely used to make short movies, promos and advertisements; etc. It should be noted that AVI format result in large files that is why it is rarely used for video streaming.
Technical descriptionIn AVI extension, file's data is divided into blocks or chunks as it is a sub-format of RIFF(Resource Interchange file format). An identification of each chunk is done by FourCC tag. File header and metadata of video(like height, width and frame rate) are identified by ‘hdrl tag' which is sub-chunk and it is mandatory. There is one another chunk which is also obligatory that is ‘movi tag' and it has actual audio or video data. The last sub-chunk is ‘idx1 tag' and it records the offsets of the data chunks. This ‘idx1 tag' is completely optional. There is one limitation of this format that it does not contain variable bitrate data.

Actual WMA compression technique was developed only for internet streaming applications and it gave tough competition to RealVideo. The other compression techniques include WMV screen and WMV image which are designed for specialized content. These files are compatible with both Mac and Personal computers ;etc. This format attracts companies those want to sell audios and videos online due to DRM technology. This is the most popular among its family members. Interlaced videos can also be played using this video extension. There is an advanced version named WMA 9 which automatically comes into play when video resolution exceeds 300,000 pixels and the bitrate 1000 kbit/sec.
Technical descriptionIt is based on DRM(Direct Rights Management), thereby, it restricts users from making unauthorized copies that are often bought online from stores. HD DVD and Blu-ray Disc are formats for physical delivery which were adapted when WMV version was standardized by the SMPTE(Society of Motion picture and Television Engineers). It is now termed as VC-1. MPEG-4 AVC, AVS and MPEG-4 ASP are other competitors against this format. Furthermore, it can also provide support to the variable bit rate, average bit rate and constant bit rate. It enables makers to use non-square pixels as well.
