File header and metadata of video(like height, width and frame rate) are identified by ‘hdrl tag' which is sub-chunk and it is mandatory. There is one another chunk which is also obligatory that is ‘movi tag' and it has actual audio or video data. The last sub-chunk is ‘idx1 tag' and it records the offsets of the data chunks. This ‘idx1 tag' is completely optional. There is one limitation of this format that it does not contain variable bitrate data.
