what is the differnce between a mp4 and a mp3?

Question

just wondering.

Answer 1

Just like MP3s work by compressing music and audio files without affecting the audio quality, MP4 files are compressed video files. MP4 is also known as MPEG-4 AVC, or advanced video coding. This new technology is going to make video files decrease in size so that they are easier to work with and support. What used to be massive video files of motion and audio are now compressed versions of the same material, called MP4s.



MP4 is the global file extension for the official container format defined in the MPEG-4 standard (ISO 14496-14)

MP4 is streamable and supports all kinds of multimedia content (multiple audio-, video-, subtitlestreams, pictures, variable-framerates, -bitrates, -samplerates...) and advanced content (officially called "Rich Media" or "BIFS") like 2D and 3D animated graphics, user interactivity, DVD-like menus... - next to nothing handled by the often used AVI



MP4 files work through compression; similar to how MP3 audio files are compressed, except these are more complex. The way these videos are compressed into very small files without affecting the quality is through dealing with specific coding issues, minimizing certain aspects, such temporal and spatial redundancies, transforming motion estimation and intra estimation into the frequency domain, and generally through compression and decompression, commonly referred to as codec.



The MP4 player works in a very simple manner. You simply purchase the “sold separately” electronic device and attach it to your computer, notebook, or TV. It’s that easy.

MP4s produce videos of DVD-quality at less than 1 Mbps through a broadband connection. This means that with an MP4 player, you can retrieve videos through an Internet connection and watch them with your MP4 player. MP4 players can also play lower MP versions, such as audio MP3s.

It looks like the same piracy issues that MP3s dealt with will arise with the MP4 technology. There are already pirated versions of movies available on the Internet. These licensing and piracy problems are bound to get out of hand as MP4 technology develops and gains popularity.

Although MP4 files are much smaller than regular video files, they will still take time to download with a broadband connection because they are still generally large files.

Answer 2

Like MP3, MP4 is simply the name of a type of computer file, but for video rather than music. MP4 players diverge from MP3 players because they have the ability to play video.



Although not quite as popular as digital music players, portable video players are becoming a more common sight.



MP4 players differ from portable DVD players in that they play computer files (in the same way that MP3 players play music in digital format) rather than discs. Size is another difference, a portable DVD player will only ever be as small as the size of a DVD disc, and you'll have to carry discs around with you.



Although many portable DVD and MP4 players can play music, MP4 players often boast more features like a radio and in some cases a microphone, clock and alarm.



MP4 players can store music and movies. Like an MP3 player, you will need a computer to use an MP4 player, and ideally access to the internet. You can watch everything from video clips to TV programmes to full length films on an MP4 player.

Answer 3

The mp4 is an mp3 with a colored screen and plays different types of file formats.

Answer 4

mp3 for songs and mp4 for videos
