AMV VIDEO FORMAT

'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,^[1].
