Summary: AVI and MP4 are prominent video formats, each with unique features. AVI, introduced by Microsoft in 1992, supports various codecs, while MP4, introduced in 2001, is versatile, accommodating audio, video, subtitles, and images. Dedicated video conversion software ensures secure format conversions.

MP4 and AVI stand out as the primary video formats used for viewing content on computers and various devices. MP4 is the preferred format for online sharing, streaming, and online playback of videos. On the other hand, AVI is well-suited for both audio and video files, compatible with nearly all video and audio players. The abbreviation AVI represents Audio-Video Interleaved, underscoring its significant role in facilitating the playback of digital videos.

Microsoft introduced AVI in the early 1990s, and it initially gained widespread compatibility with media players on the Windows Operating System. As Apple’s operating systems emerged, AVI also became playable on iOS-based media players. Various codecs, such as DivX and Xvid, are available to compress audio and video files for storage within AVI containers, effectively preserving their quality and reducing file size.

Structure of the AVI File

The AVI file format exhibits a straightforward structure comprising two essential components. The first component is a header file, which stores metadata about the file, including its size, name, frame rate, and other relevant properties. This header section is labeled with the ‘hdrl’ tag. The second part encompasses information about the audio and video files and is designated by the ‘movi’ tag. Some other codecs may use a single ‘movi’ tag to encompass the compressed data file.

Although the extension of the video file remains AVI, the file format of the video-audio file is RIFF (Resource Interchange File Format).

What are the Benefits of the AVI File?
  • Because Microsoft is the maker of AVI file format, it supports all the media players supported by Windows.
