What is an AVI file?

An AVI file (Audio Video Interleave) represents one of the pioneering multimedia container formats, introduced by Microsoft in November 1992 as part of the Video for Windows technology. Built on the Resource Interchange File Format (RIFF) specification, AVI was designed to provide a simple yet flexible container for storing synchronized audio and video streams, revolutionizing how digital video content was captured, edited, and distributed on personal computers.

As a container format rather than a codec, AVI serves as a wrapper that can hold video and audio data compressed with virtually any codec, from uncompressed RGB to modern H.264 streams. This flexibility, combined with its chunk-based structure that allows efficient seeking and editing, made AVI the foundation for desktop video editing and the standard format for digital video capture, establishing it as a cornerstone of the digital video revolution throughout the 1990s and 2000s.

Technical Foundation

  • RIFF (Resource Interchange File Format)
  • Chunk-based file structure
  • OpenDML extensions (AVI 2.0)
  • Interleaved audio/video streams

Container Specifications

  • .avi (standard extension)
  • MIME type: video/x-msvideo
  • Multiple codec support
  • Little-endian byte ordering

Why Choose AVI Files?

AVI remains the cornerstone of digital video production, offering unmatched universal compatibility, flexible codec support, and professional editing capabilities that have powered the video industry for over three decades. While newer formats excel in specific areas, AVI's simplicity, reliability, and broad software support make it indispensable for professional workflows, legacy content preservation, and applications requiring maximum compatibility.
