It is a compressed multimedia container format that can hold both video and audio file with a smaller file size without too much loss in quality. MPEG-4 can make distinctions among different objects in the video (such as people and background) intelligently, then isolated them and compressed one by one. And the video and audio tracks are compressed separately. Video is compressed with MPEG-4 video encoding while audio is compressed as AAC. That’s why MPEG-4 can reduce the file size essentially. With this way, the transmission for audio / video also speed up to a large extent.
