MP4 stands for MPEG-4 Part 14, which is a digital multimedia container format that is used to store video, audio, and other data, such as subtitles and still images. MP4 files use lossy compression to reduce the file size while retaining a high-quality video and audio output.
MP4 files are widely used for video playback on a variety of devices, such as smartphones, computers, and tablets. They are supported by many media players and video editing software, making them a versatile and widely used format.
In addition to storing video and audio data, MP4 files can also contain metadata, which provides information about the file, such as title, artist, and genre. They can also be encrypted for digital rights management purposes.
MP4 is a popular format for online video streaming, and is used by many video sharing platforms such as YouTube and Vimeo. It is also commonly used for video podcasts and online courses.
