Chinese MP4/MTV Player is a class of flash based Digital audio player, mostly manufactured in China, capable of displaying images, videos, and text files. Although commonly called MP4 players, they are usually unable to play MP4 format videos and are limited to proprietary file formats such as MTV, DMV, MPV and AMV. This is beginning to change however, as more players are starting to support MP4 files. They are a variety of S1 MP3 Player.Most players include a viewer for image files, such as JPG and BMP. They also play MP3 and other audio files. Conversion software is usually included on a CD-ROM. Videos are playable in the AMV or MTV format, and are convertible from other common formats such as SMV using the conversion software. They also normally include an ASCII text viewer, so that e-books can be read, such as those downloaded from Project Gutenberg. Some units include a phone book application, a voice recorder, and an FM radio, making it possible to record FM broadcasts. Finally, some units include video games in the firmware.

MP4 players arent all that great. They dont have really good image quality. nothing no point to brag they break in 1 - 5 mounths mp4 is better then an mp3 next year it will be mp5 just a little better quality that's all I'm not totally sure, although I know that a mp4 sound file exists.... it may just be a hightech- clearer sounding mp3 player. I don't even think there is even a mp4! Sounds impossible! Don't believe what ever one says! You believe them every once and a while! im no expert but its basically a device that plays videos like the ipod video its just the format in which its in have no clue windows media player and real player have mp4. last i saw an mp4 file it was a video file. other than that i dont know except these two media players have it. Mp4 is itunes (apple's) way of protecting it's music that you bought from them. MP3 is an antiquated audio-only format that is, by virtue of having been around so long, universal to every digital music player out there.

MP4 is a "container" format that can combine any combination of compatible audio, video, still image, and text files into one file. The audio portion of this format is identified by the .M4A file extension (video is .M4V, if you hadn't guessed), sometimes also known as the AAC format. M4A sounds much better than MP3 at the same compression rate, which is why it's the default format for iPods.
