AMV
is a
video
file
format, produced for use in
Chinese MP3/MP4/MTV Players; classified as
S1
MP3 Players. Note that despite the word "MP4" in
the description of several players, this
is not an
MP4 file format. Video compression ratio is low,
compared with other formats, though
as
the files are of low resolution and frame rate, file
sizes are small compared to DVD/VCD/etc.
(in
a bytes-per-minute sense). Encoding and decoding are
less processor-intensive than other
contemporary
formats (i.e. faster to encode on, say, desktop
computer, and less hard on the
batteries
of the portable device), as in fact very little
"encoding" is actually done. |
