The AVI multimedia file format is a proprietary format developed by Microsoft in the early 1990's as a means to store video and audio data for its Video for Windows software. The format has evolved over time to incorporate new features to match those of rival formats.

Although the AVI file format enjoys support from most popular video editing software the format does have its limitations. Other multimedia container formats such as MP4 offer better compression ratios with higher quality results and better compatibility with older players.

The MP4 video format is a standard format for video encoding and storage. In order to minimize the file sizes the format employs a lossy compression method which reduces the amount of data to store the video content without any noticeable loss in quality.

Due to their small size and efficient compression methods the MP4 format is ideally suited to online video streaming. The MP4 format may use a variety of CODECs which are usually supported by most MP4 players with additional CODECs downloadable if needed.
