MP4 is a video file type that is widely used both on the Internet and on portable media devices. SMV files are video files created through VideoLink Pro. These files are highly compressed and are therefore ideal for transmitting video through e-mail. Some MP3 players, such as the Global Sources Direct player and TRIO Onyx Portable Media Player, can also recognize SMV files. If you would like to convert an MP4 video to SMV, the file must first be converted into AVI.
