As our original video format, it is necessary for us to have some basic knowledge of MP4 video format. Here are some brief introductions of MP4.
MP4 (MPEG-4): MPEG-4 uses further coding tools with additional complexity to achieve higher compression factors than MPEG-2. In addition to more efficient coding of video, MPEG-4 moves closer to computer graphics applications. In more complex profiles, the MPEG-4 decoder effectively becomes a rendering processor and the compressed bit stream describes three-dimensional shapes and surface texture. MPEG-4 supports Intellectual Property Management and Protection (IPMP), which provides the facility to use proprietary technologies to manage and protect content like digital rights management. What's more, MP4 is widely used in the portable media player, it contains smaller files and better quality in comparison, it is convenient for inter-transmit. MP4 is a real popular video format.
As our target audio format, we need know more about MP3 so that we can clear what we can get by converting MP4 into MP3.
The General Concept of MP3: MP3 is an audio-specific format that was designed by the Moving Picture Experts Group as part of its MPEG-1 standard and later extended in MPEG-2 standard. The first MPEG subgroup - Audio group was formed by several teams of engineers at Fraunhofer IIS, University of Hannover, AT&T-Bell Labs, Thomson-Brandt, CCETT, and others. MPEG-1 Audio (MPEG-1 Part 3), which included MPEG-1 Audio Layer I, II and III was approved as a committee draft of ISO/IEC standard in 1991, finalized in 1992 and published in 1993. Backwards compatible MPEG-2 Audio (MPEG-2 Part 3) with additional bit rates and sample rates was published in 1995.
Main Advantages of MP3: The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 11 times smaller than the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. As we can see, MP3 has a lot of advantages, so convert MP4 into MP3 is not a bad choice.
