What is AMV?
Compressed video format produced by MTV for use in Chinese MP3/MP4/MTV Players.
Usually saved in low resolutions from 94x64 to 160x120 pixels.
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 M4R?
M4R is the standard file format for Apple iPhone ringtones. The M4R is encoded
with Advanced Audio Coding (AAC). The AAC is a standardized, lossy compression
and encoding scheme for digital audio. AAC has been standardized by ISO and IEC,
as part of the MPEG-2 and MPEG-4 specifications.
