About MP4 file
.mp4 is the filename extension for the multimedia container format standard MPEG-4 Part 14. This format is often referred to simply as MP4.
MP4 is similar to the MOV format, but specifies support for IOD and some other MPEG features. MP4 files may contain any number of digital audio, digital video, and subtitle streams. MP4 allows streaming over the Internet. Audio-only MP4 files generally have a .m4a extension; MP4 files with audio and video generally use the .mp4 and .m4v extensions. |
