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 WMA?
A WMA file is in most circumstances encapsulated, or contained, in the Advanced Systems Format (ASF) container format, featuring a single audio track in one of following codecs: WMA, WMA Pro, WMA Lossless, or WMA Voice. These codecs are technically distinct and mutually incompatible. The ASF container format specifies how metadata about the file is to be encoded, similar to the ID3 tags used by MP3 files. Metadata may include song name, track number, artist name, and also audio normalization values.
