What is an AVI file?

An AVI file is a file saved in a multimedia container format created by Microsoft. It stores video and audio data that may be encoded in a variety of codecs such as DivX and XviD. AVI files typically use less compression than similar formats such as .MPEG and .MOV.

More Information

The AVI format is based on the Resource Interchange File Format (RIFF) which is a container format that was originally released in 1991 to store multimedia. The AVI format was introduced a year later in 1992 by Microsoft and is supported by various video players. However, the player must support the codec used to encode the video data.
