AVI The AVI file format is one of the most widely used multimedia containers ever devised. AVI, which stands for audio video interleaved, was first introduced to the public by Microsoft in 1992 as part of their 'video for windows' multimedia framework. Being a container format, an AVI file with the .avi filename extension can exist with both video and audio content synchronized for playback. The format can thus be used by authors to edit and encode audio video sequences or just video sequences. The Digital video AVI format exists in two forms, Type 1 and Type 2.
WEBM The WebM extension is an HTML5 standard for distributing and viewing videos over the web. WebM is primarily designed for use on the web using the HTML5 tags . Its design is based on the Matroska container, video compression in the WebM file format is often done with VP8-enabled technology. WebM is a high quality, open-source, standard video format which lets users play videos on the web. It is specifically catered for video playback on the web and in web browsers. A unique aspect about the WebM extension is that it adapts to various bandwidths, processing environments, and is used over a wide range of media playing devices. The audio compression technology used in the WebM file extension is known as the OGG Vorbis Compression.

The AVI format was derived from the RIFF or resource interchange file format which is a generic container format. Digital video that is interleaved can be stored natively as a single stream conforming to the type-1 specification of the AVI file format. This has the disadvantage however of not being compatible with the video for windows framework. In general, the number of blocks in .avi files determine the amount of overhead. Overhead associated with the audio stream is determined by which codec is used to encode the stream for example AC3 or MP3-VBR.
