What is an MP4 file?

An MP4 file is a multimedia file commonly used to store a movie or video clip. It may also contain subtitles or images. MP4 is short for MPEG-4 Part 14, which is a container format based on the QuickTime File Format (QTFF) used by .MOV and .QT files.

MP4 files use MPEG-4 compression, a standard developed by the Moving Picture Experts Group (MPEG). This format includes separate compression for audio and video tracks. Video is compressed with MPEG-4 video encoding and audio is compressed using AAC compression, which is the same type of audio compression used in .AAC files.

Much of the MP4 format's popularity can be attributed to Apple's iTunes Store since the format is used for distributing much of the media downloaded from the store. The MP4 format is also commonly used for streaming video on the Internet and is supported by a wide range of video programs and various hardware devices.

How do I open an MP4 file?

Most popular media players can play MP4 files. Microsoft Movies & TV (Windows), Apple QuickTime Player (Mac), MPlayer (cross-platform), and VLC media player (cross-platform) are all popular programs that PC users can use to open and play MP4s.

iOS and Android users can play MP4s in those OS's default video players by double-tapping the files. Users looking for more advanced playback options can play MP4s in VLC for iOS or VLC for Android.

Those looking to convert MP4 videos to other formats can do so using HandBrake (cross-platform).
