| Description | Audio Video Interleaved (also Audio Video Interleave), known by its initials AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows software. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. | H.264 is a video compression standard based on block-oriented, motion-compensated coding. It is by far the most commonly used format for the recording, compressing, and distributing of video content, used by 91% of video industry developers as of September 2019. It supports resolutions up to 8K UHD. The H.264 video format has a broad application range covering all forms of digitally compressed video, from low-bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding. |
| Technical details | AVI is a derivative of the Resource Interchange File Format (RIFF), which divides a file's data into blocks, or 'chunks.' A FourCC tag identifies each 'chunk'. An AVI file takes the form of a single chunk in a RIFF formatted file, which is then subdivided into two mandatory 'chunks' and one optional 'chunk'. | |
