A: MP4, a container format that can combine different multimedia tracks into a single file, was developed by MPEG (Motion Pictures Experts Group), an international organization that develops and manages publishing standards for digital audio and video. MP4 files support text and graphics. More advanced MP4 files will contain streams for 2D and 3D animation and user interactivity (such as DVD menus) MPEG-4, the video compression standard behind MP4 files, is an open standard that is publicly available for developing software or hardware. All files encoded in an MPEG-4 standard are associated with the extension ".mp4".
A: MP3 format, short for MPEG-1 Audio Layer 3, a revolutionary digital audio format, is developed by Fraunhofer-Gesellschaft and Thompson Multimedia in the late 1980s and brought to the mainstream through the Internet in 1997. It is a common audio format for consumer audio storage, as well as a standard encoding for the transfer and playback of music on digital audio players. MP3 is a near-CD quality file format for sound files and is very popular for music on the web. As an audio-specific format, MP3 becomes more popular when people use it to swap music online because of its powerful compression.
A: People convert MP4 files to MP3 format for various purpose, however, most of them convert MP4 for the two common ones, first they want to extract audio stream from the MP4 video files and save as MP3 format; second their portable devices do not recognize MP4 format at all, but these devices are capable of playing MP3 files without any compatible issues.
A: This is a good question, but unfortunately, the short answer is YES. Since MP3 is a lossy audio format, converting any audio formats (e.g. MP4) to MP3 is a quality-loss process, but with the build-in Lame MP3 encoder, the encoded MP3 files sound like a faithful reproduction of the original MP4 music collections to most listeners.
