MPEG-4 (MP4) is a container video format that can store multimedia data, usually audio and video. It is compatible with a wide range of devices and operating systems, using a codec to compress file size, resulting in a file that is easy to manage and store. It is also a popular video format for streaming over the Internet, such as on YouTube. Many consider MP4 to be one of the best video formats available today.
MP4 files open in the operating system's default video player. Simply double-clicking the file opens it. There is no need for third-party software. On Windows, it opens in Windows Media Player. On Mac, it opens in QuickTime.
On some devices, particularly mobile, opening this file type can be problematic. MP4 is a container that contains various kinds of data, so when there is a problem opening the file, it usually means that data in the container (an audio or video codec) is not compatible with the device’s OS. To resolve this issue, try VLC media player.
