The AVI file is divided into blocks or chunks, each identified by a FourCC tag. Each chunk is subdivided into 3 sub-chunks. The first sub-chunk is crucial and holds data like video codec, frame rate, audio format, etc. The second chunk contains the actual video and audio data. The third chunk contains the ‘idx1’ tag, which is optional and contains the info. regarding different timestamps of the video file.
