Features of MP4:
The advantage of the MP4 technology is that the video files are played in DVD quality at less than 1 Mbps (through a broadband connection). With a MP4 player, one can take videos through an Internet connection and watch them immediately in perfect quality. Lower MP versions can be played in the player, such as audio MP3 files.
Disadvantages, though not many, exist through the realms of MP4 technology. Piracy concerns in the MP3s still continue with MP4. Licensing and piracy problems continue and become even greater as long as MP4 gains its popularity. Despite the small size of a MP4 file, it still takes a while to download the file in a broadband connection. In a nut shell, the file is generally still large, even if it is compressed.
