Avi is a video format proposed by Microsoft back in 1992. Currently avi is supported by most of the existing players and video players.
Turntables
There are hundreds of avi players. Some are multi-format, others only support one avi format. KMPlayer is a popular utility for viewing wmv, flv, mp4, mpeg and avi files. KMPlayer supports professional subtitling and high definition video.
Another multi-format player that supports the avi format is Windows Media Player (standard for Windows). In general, the Microsoft player copes well with its own format, but there are problems with playing "heavy" large HD files. Also, users often complain about the "mixing" of audio tracks (translation and original) when watching movies in avi format in Windows Media Player.
Free Avi Player only supports avi format. But it takes up little disk space and uses RAM economically. Thanks to this, video files are easy to watch, films and clips do not "slow down". However, the simplicity of the player baffles some users - they complain about low functionality and poorly thought out design.
Converters
There are specialized tools for translating from various formats to avi. One of the most popular is Movavi shareware. Conversion speed is high, the number of input formats exceeds 40. Also, the converter offers a rare (for such utilities) function "Screen Capture". Movavi also allows you to make professional subtitles.
Most of the existing video converters allow you to convert the video of each input format to another output in the library. In other words, avi is the same peer-to-peer format as mkv, wmv, or mpeg.
The Format Factory video converter has an unassuming design that frightens off lovers of "interface beauty". Nevertheless, this free program has amazing functionality (over 25 input and output formats) and high speed. What's more, in addition to converting files to avi format, Format Factory can convert videos to animated.
Codecs
For high-quality playback of avi-files, you may need special encoding utilities - codecs. They are installed on top of the operating system and "come to the rescue" only when it is really required. Packages of codecs CCCP and K-Lite Pack allow you to watch videos in avi format without unnecessary problems.
