What is AMV?
AMV is a proprietary video file format, produced for MP4 players, as well as S1 MP3 players with video playback. There are now two different MTV formats: the older one for the Actions chip, and a newer one for ALi's M5661 chip. This format for ALi one was ALIAVI.
The container is a modified version of AVI. The video format is a variant of motion JPEG, with fixed rather than variable quantisation tables. 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.
Low decoder overhead is paramount as the S1 MP3 players have very low-end processors (a Z80 variant). Video compression ratio is low ¡ª around 4 pixels/byte, compared with over 10 pixels/byte for MPEG-2 -- though as the files are of low resolution (96¡Á96 up to 208¡Á176) and frame rate (10, 12, or 16 frame/s), file sizes are small in bytes per second. With a resolution of 128¡Á96 pixels and a framerate of 12 frame/s, a 30-minute video will be compressed into 80 MB.
What is M4A?
Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.
