Audio Video Interleave (better known as AVI) is a very popular multimedia container created by Microsoft.
AVI files enable synchronous audio-with-video playback because they contain both video and audio data.
AVI editors allow their users to perform a wide range of actions, including trimming, cutting, and cropping videos.
Furthermore, users may also resort to such apps for applying effects onto their videos or for adding watermarks in order to claim ownership.
Additionally, AVI editors may be used for adding subtitles or to export video files to other formats.
