Resource-intensive - MP4 processing needs lots of computing resources because a single MP4 file can contain various media data and metadata.navigation options, menus, 3D graphics, VR videos, etc. Extensible Application – Support for metadata means that the MP4 file can be integrated with many other user interaction features, e.g.Flexible Modification – Each data is kept independently so that users are allowed to extract audio and subtitles from MP4, remux MKV to MP4, etc.And it's expected to get further development along with future compression methods. Less Quality Loss - MP4 can collaborate with many efficient codecs that achieve less quality loss and smaller file size.Versatility – MP4 is suitable for HTTP streaming, broadcasting, and editing.But it's not perfect and comes with both excellent features and some drawbacks. It gets widely native support on TVs, mobile phones, computers, multimedia software, and web browsers. In the era where many file formats co-exist, MP4 hits a home run with its high compatibility. Unknown boxes can be skipped syntactically and media data can be stored unstructured either in boxes (usually mdat or idat) under the corresponding root or in a separate file. That's because, as opposed to defining a strict structure for media files, MP4 allows custom structure and hierarchy for media of different types. Note: After parsing an MP4 file, you might find some atoms are missing, compared to the lists above. udta: Holds the user and track information.

mvhd: Holds the video header information with full details of the video.stsc: Indicates the sample-to-chunk table.stts: Indicates the sample-to-time table.mfra: Contains random access to video fragments.

pdin: Stores progressive video loading/downloading information.

ftyp: Stores information about the file type, description, and the common data structures used.

While metadata indicates the flags for timestamps, random access, and so forth.Įach data in MP4 is stored in a basic structure called atom or box and no data is outside a box. The media data includes streams of video, audio, and subtitles. The data in an MP4 file is mainly divided into two segments – media data and metadata. As a result, it becomes the basis of many file formats from the MPEG-4 family, like say, 3GP.

In 2004, MP4 was generalized into the ISO Base Media File Format (ISO BMFF) and used for defining the structure for time-based media files. In 2003, it was revised into MPEG-4 Part 14 (ISO/IEC 14496-14:2003) and is commonly known as MP4 file format version 2. In 2001, the first version of the MP4 file format was created based on the QuickTime format specification and published as a revision of the MPEG-4 Part 1: Systems. And it has gone through several revisions since its birth. It was initially developed to hold low-data video and audio files for streaming over the internet. MP4 was standardized by the Motion Picture Experts Group (MPEG), an alliance of working groups established jointly by ISO and IEC. m4b: MPEG-4 audio format container for audiobooks and podcasts. m4v: MPEG-4 Visual bitstreams and sometimes standing for the video stream in MP4 file.

m4p: MPEG-4 audio with copyright protection like Apple DRM. m4r: MPEG-4 audio used as Apple Ringtone. m4a: MPEG-4 files with audio only and often found in Apple devices, e.g. mp4: The general MPEG-4 files that contain both video and audio. But since it can hold different types of multimedia files, it could come with various filename extensions as below: The official and the most common file extension for MP4 is. But note that, MP4 stores data instead of compressing them, so it has to work with other codecs, for example, H.264/AVC and HEVC for video, AAC, and MP3 for audio, and 3GPP Timed Text for subtitles. Simply put, MP4 acts like a wrapper around multimedia files and associated data that's necessary for playing the file correctly.

In addition to video and audio, the MP4 format container also holds still images and subtitles. MP4, aka MPEG-4 Part 14 (or ISO/IEC 14496-14), is the 14th part of the MPEG-4 standard that defines the container format for compressed digital audio and visual data. With a better understanding of MP4 file format, you can play, edit, and share MP4 files without any trouble. In this post, we will introduce MP4 file format from its features, specifications, history, advantages, disadvantages, and the differences between MP4 and other formats. But do you know what MP4 is on earth? Why it is so popular? mp4 files from digital cameras, smartphones, online video platforms, and so forth. MP4 seems like the most popular video format used everywhere in our digital life.
