Audio Video Interleave (AVI) is a means of digitally storing multimedia audio and video content in a file for playback. Introduced in the early 1990s, the AVI format is a built-in feature of the Windows computer operating system (OS). AVI format files use the .avi file extension and consist of a header tag followed by a series of information blocks. The header part of the AVI format file provides details about the content of the file, such as width, height, and frame rate, while the information blocks store the actual audio and video data. One of the main advantages of the AVI format is its ability to be played on most computers in the world.

To play a media file of any format, including AVI format, compatible software that understands the details of the file content is required. When the appropriate software program is not available to open and play a media file, the user is presented with a message box stating that Windows can open the file. Options are provided to allow the user to select the program from a list of available programs or use the web to locate the program. The AVI format usually eliminates the need to select a program.

In the years after the AVI format began, many video techniques were introduced that were not conceived during the definition of the AVI specification. Also, the compression systems used to optimize space requirements when writing AVI files are not as effective as the techniques used in developing newer multimedia formats. As such, the AVI format requires approximately 5 megabytes (MB) of storage space per hour of video and does not support the ability to specify media details such as aspect ratios, time codes, or audio sample rates below. 32 kilohertz (kHz).

Many new media file formats are making their way onto the Internet, including Ogg, MOV, and NUT. Motion Picture Experts Group (MPEG), however, is emerging as a default standard and its popularity is growing. Software programs to support the creation and playback of MPEG media files are included in Windows and Mac operating systems.

What is AVI format

Digital videos can be saved in many formats, each of which corresponds to a specific extension of the file that contains it. Today we are talking about the AVI format, detailing its characteristics and how it works.

AVI (Audio Video Interleave) is a container video and audio format that Microsoft launched in 1992. Despite being the leading format for years, lately it has been losing popularity by leaps and bounds as it has not been able to adapt to high resolutions they have the vast majority of televisions today. Therefore, competitors who for years had tried to catch up with AVI have overtaken him.

Characteristics of the AVI format

It contains video with very good quality.
One of its biggest disadvantages is that the weight of the files is always very high, which means that videos in this format are not suitable for hanging on the Internet.
It can be viewed with most players on a Windows or Mac computer, as long as the video and audio codecs for each type of player are installed.
Generally, the codecs that have a higher compression capacity and a fairly good quality are DivX and XviD; They are often used for long-length videos such as movies.
It is a format that is widely used to save original videos that have been captured with a digital camera.

How does the AVI format work?

This format allows a single video data stream and multiple audio streams to be stored simultaneously. One of the main characteristics that distinguishes AVI from other formats is that audio and video can be in any other format such as MP3 for audio and DivX for video. It is precisely for this reason that AVI is a container format.

We have commented that the AVI format supports various audio streams. Why? Because it can contain several soundtracks in different languages. Thus, depending on the user’s preferences, the multimedia player is in charge of deciding which of the audio streams it plays.

How is the AVI format formed?

This container audio and video format is divided into a series of fragments, which are called chunks, each of which has a certain identifier, which is known as the Four CC tag. Generally, the AVI format is divided into two chunks, although sometimes there is an optional third:

First Chunk: Also known as a header, its function is to describe meta information about the file, such as the dimensions of the video image.
Second chunk: Contains the audio streams and the video stream.
Third chunk: It is optional and if it exists, it plays the role of acting as an index for the first and second chunk.
