AVI Format and Video Compression
AVI is the Microsoft-specified format for saving digital videos. (AVI = Audio-Video Interleaved)
AVI video files are very large and this can lead to storage difficulties. In order to reduce the amount of memory needed to save AVI files, compression methods have been developed, otherwise known as Codecs (Compressor Decompressor).
To be able to play an AVI video, the PC has to have access to the same decompression Codec that was used to compress the file originally.
Unfortunately, however, the number of Codecs available in the market has been mushrooming recently, meaning that an AVI created on one PC will only work on another provided the same Codec happens to have been installed.
