MP4, or MPEG-4 Part 14, is a common media format used to digital video files and streaming audio. You can add or delete basic files properties--such as "album", "artist", or "subtitles"--using your computer's operating system (specifically, Windows Explorer). Using a third-party program (such as File Property Edit), you can edit more advanced settings such as the "File Creation Date."
