AMV video origin and history

AMV is a video file format, used by Chinese-made portable MP3 players and created to allow video playback capabilities on inexpensive without increasing the cost of those players with the license royalties (and more processor power). AMV is a video file format contain a MTV video stream and a MP3 audio stream. The Chinese MP4/MTV Player (sold as "MP4 Player" or "PMP", for Personal Media Player) that these video-files produced for are flash based digital audio players, mostly manufactured in China, capable of viewing images, videos, and text files. Although commonly called MP4 players, they are unable to play true MP4 (MPEG-4 AVC H.264) formated videos and are limited to the proprietary file formats such as MTV, DMV, MPV, ACT and AMV. They are a kind of the S1 MP3 Player. This is beginning to change however, as more and more top-branded portable players are starting to support true MP4 (MPEG-4 AVC H.264) video files.


AMV Video File Format

When playing AMV formats, there is clearly some image de/compression taking place, as can be demonstrated by a simple calculation (see the MTV Video Format article). The image compression is, however, low by modern standards (around 4 pixels/byte, compared with over 10 pixels/byte for MPEG-2). With a resolution of 128 x 96, and a frame rate of 12 fps, a 30 minute file will be around 80 MegaByte in size.
