What Is AVI?

What is AVI? AVI is also known as Audio Video Interleaved. It is a file format that combines audio and video data into a file for simultaneous playback. The AVI format was developed by Microsoft in November 1992 and it is now commonly used for file transfers and storage of video and audio tracks.

Due to its high compatibility, AVI files are supported not only on Windows systems but also on many other major platforms such as Mac, Linux, and Unix. Similarly, most media players can recognize it.

A complete AVI file can be composed of three parts. The first is the header section, which displays general information like file size, frame rate, and parameters about the compression algorithm used. The second part is the data part, which includes graphics and sound sequence data. The last part is an index section on file locations and allowed access functions.

What Is MP4?

What Is MP4? It is created by ISO/IEC and the Moving Picture Experts Group (MPEG) according to the ISO/IEC 14496-12: 2001 standard. Therefore, MP4 is an international standard for audiovisual coding.

MP4 is regarded as a digital multimedia container format, which is essentially a file containing a bunch of compressed data. The standard specifies how to store data in the container itself, but not how the data is encoded.

With the high compression used in MP4 videos, this makes the file size much smaller than other video formats. Reducing the file size does not immediately affect the file’s quality. Almost all original quality is preserved. This makes MP4 a portable and network-friendly video format.
