It is hard to overestimate the role that the internet has played in recent years for multimedia and entertainment, including downloading MP4 files. There was a time when the only kind of audio you could download was minuscule midi files. And that was about the limit of what you could carry from one computer to another, because all the removable medium you had in those days was the measly floppy disk. At that time, if you told anyone they would be able to download and carry hundreds of music files of the highest quality and with stereo sound, it would have sounded like science fiction. But then came the MP3.
Now, something similar is happening with the MP4. Only this time it is about video, and not audio & data.
Imagine waking up in the morning and wanting to watch some latest Hollywood box office hit. You go to your favorite site for MP4 downloading, perhaps make an online payment with your credit card, and in a few minutes you have it on your hard disk. Then you upload it to your portable MP4 player, and take it with you on your way to work. Watch it on the bus or train, watch it during the lunch break, or even watch it during work hours on a particularly slow day. Back home, take it to bed with you. If it's romantic stuff, watch it with your spouse in bed, lying side by side, your heads close together. Sounds like a pretty good thing to me; what's your feeling?
Yes, this has now become possible, thanks to MP4 technology. MP4 uses high-class codecs for encoding and decoding (incidentally, that's where the name comes from) video data into compressed format (thus reducing file size) while not compromising on visual quality too much. This results in high quality movies which are nevertheless so small that they can be distributed over the internet, mainly through MP4 download sites and services, and also carried easily on recordable media or lightweight personal players.
There has been a great expansion in storage media capacity and bandwidth in recent times, and this has certainly helped the online multimedia boom. But surely a larger part is played by modern high-quality movie encoding technology, which makes MP4 downloading possible.
