An AVI file, which stands for Audio Video Interleave, is a widely used multimedia container format that was introduced by Microsoft in 1992. This format is designed to store both audio and video data, making it a popular choice for storing movies, video clips, and other multimedia content. AVI files use a lossy compression method to reduce file size while maintaining reasonable quality, making them suitable for various applications, including video editing and playback on different media players.

The AVI file format is based on the Resource Interchange File Format (RIFF) architecture, which organizes data into chunks. Each chunk contains a specific type of information, such as video frames, audio samples, or metadata. One of the notable advantages of AVI files is their ability to support multiple codecs, allowing users to choose from a wide range of video and audio compression methods. However, the flexibility in codec selection can lead to compatibility issues, as not all media players or devices may support the same set of codecs.

Over the years, other container formats like MP4 and MKV have gained popularity due to their more efficient compression algorithms and broader compatibility across devices and platforms. Nevertheless, AVI remains a significant format in the world of multimedia, especially in legacy systems and certain niche applications that still rely on its characteristics and backward compatibility with older software and hardware.

An MP4 file, short for MPEG-4 Part 14, is a widely used digital multimedia container format. It was developed by the Moving Picture Experts Group (MPEG) and is designed to store various types of multimedia content, such as video, audio, subtitles, and images, all within a single file. MP4 files are known for their efficient compression, which allows for high-quality media representation while keeping file sizes relatively small. This makes them ideal for streaming and sharing media over the internet or other digital platforms.

MP4 files are compatible with a wide range of devices and media players, including computers, smartphones, tablets, and smart TVs. The format's versatility and widespread support have contributed to its popularity in both personal and professional contexts. Many online platforms, such as YouTube and social media networks, utilize MP4 as their default video format due to its efficient streaming capabilities and broad compatibility.

Due to its flexibility, MP4 has become the standard format for storing video content in various applications, from capturing home videos on smartphones to distributing high-definition movies. Additionally, its ability to include multiple data streams, like audio tracks, subtitles, and chapter information, makes it a valuable choice for content creators and multimedia enthusiasts seeking a unified solution to store and share their creations.
