What are MP4 files and how to open them

What is a MP4 file?

MP4 files have multiple uses, and MPEG-4 Video is one of them. Read more about the other uses further down the page.

MPEG-4 Video

The MP4 is short for MPEG-4, and is one of the most common formats for audio and video. The MP4 file format is often thought of as the evolution of the MP3 file format, with the MP4 format providing more functionality and flexibility - and support for video, which the MP3 format lacks.

MP4 is a so-called "container format", which means that you can store different data streams inside a single MP4 file. Such data streams can contain e.g. video, audio, images, and subtitles.

The format also allows MP4 files to be streamed over the internet, so when you watch a video online, it is highly likely that it is an MP4 file.

Native Instruments Stems audio

The Stem file format (.stem.mp4) is a variation of MPEG-4 audio files invented by Native Instruments.

A Stem file consists of 5 separate tracks: 4 stems (the individual parts of the song such as drums, bass, melodies, and vocals) and a master file which is the mastered mix of all stems.

Supporting software can playback the individual tracks (stems) within a single file.

A Stem file can be played as a regular MP4 audio file, provided that the software supports the Apple Lossless Audio Codec.
