What is a multimedia container format?
A multimedia container format is a file format that can hold various types of multimedia data such as audio, video, images, and subtitles. It acts as a container or wrapper for these different types of data, allowing them to be stored together and played back as a single file.

Key Features of AVI format:
- AVI files are capable of storing both audio and video data, making them suitable for movies, video clips, and other multimedia content.
- They support various audio and video codecs, which are used to encode and decode the data within the file. This allows for flexibility in terms of the types of audio and video formats that can be used.
- AVI files can also contain additional data such as subtitles, metadata, and interactive menus.
- They are platform-independent, meaning they can be played back on different operating systems and devices.

These chunks are then interleaved or placed in a specific order within the file, allowing for synchronized playback of the audio and video.

Advantages of AVI format:
- AVI files are widely supported by various media players and video editing software.
- They have relatively good video and audio quality, depending on the codecs used.
- AVI files can be easily converted to other video formats if needed.
