What is an AVI file?
An AVI file is a video file saved in the Audio Video Interleave (AVI) multimedia container format created by Microsoft. It stores video and audio data that may be encoded in various codecs, including DivX and XviD.
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 still commonly used today.
The AVI video format can be used to store high-quality video and audio and typically uses less compression than other similar video formats such as .MPEG and .MOV. This results in very large AVI file sizes, which can be problematic for users with limited space.
How do I open an AVI file?
You can open AVI files with various video players, such as Microsoft Movies & TV (Windows), Microsoft Windows Media Player (Windows), Apple QuickTime Player (macOS), Adobe Premiere Pro (multiplatform), and VLC media player (multiplatform).
NOTE: Although many video players support AVI files, the player must support the codec used to encode the video data in order to correctly play the video. For additional information, view the FileInfo.com Playing AVI Files help article.
