    The container is a modified version of AVI. [1] The video format is a variant of Motion JPEG, with fixed rather than variable quantisation tables. [2] The audio format is a variant of IMA ADPCM, where the first 8 bytes of each frame are origin (16 bits), index (16 bits) and number of encoded 16-bit samples (32 bits); all known AMV files run sound at 22050 samples/second.
