MPEG-4 Video
| Data type | Video |
| MIME type | video/mp4 |
| Developer | Moving Picture Experts Group (MPEG), ISO/IEC JTC 1/SC 29 |
| Primary use cases | Online video streaming (YouTube, Netflix, TikTok, Instagram); video sharing on social media; mobile video recording and playback; video-on-demand delivery via HLS and DASH; general-purpose video distribution across web and desktop applications. |
What is the MP4 file format?
MP4 is a widely used multimedia container format designed for storing video, audio, subtitles, and metadata. It is the de facto standard for online video distribution due to its high compatibility and efficient compression.
MP4 file characteristics
| Data type | Video |
| MIME type | video/mp4 |
| Container format | MP4 (MPEG-4 Part 14), based on ISO Base Media File Format (ISOBMFF) |
| Video codec | H.264/AVC (most common), H.265/HEVC, AV1, MPEG-4 Part 2, H.263, VP9 (limited support) |
| Audio codec | AAC (most common), MP3, AC-3, EAC-3, ALAC, Opus |
| Resolution support | Up to 8K (7680×4320) and beyond, depending on the enclosed video codec and its profile/level |
| Frame rates | Any frame rate supported by the enclosed video codec; common values: 23.976, 24, 25, 29.97, 30, 50, 59.94, 60, 120 fps |
| Color depth | 8-bit standard; 10-bit and 12-bit supported when using H.265/HEVC or AV1 |
| Color space | YUV (YCbCr 4:2:0 standard); BT.601, BT.709, BT.2020 depending on codec and profile |
| Bitrates | Variable; typically 500 Kbps – 50 Mbps for video depending on resolution and codec |
| Metadata | Supports extensive metadata via iTunes-style atoms (title, artist, album, year, description, cover art) and MPEG-7 descriptors; GPS location, creation date, device info commonly stored by smartphones |
| Structure type | Multimedia container (hierarchical atom/box structure) |
| Standard / Specification | ISO/IEC 14496-14:2020 (MPEG-4 Part 14); built on ISO Base Media File Format ISO/IEC 14496-12 |
| Typical file size | Highly variable: ~1 MB per minute at low quality (360p, ~500 Kbps) up to ~1.5 GB per minute for uncompressed 4K RAW; typical 1080p H.264 video runs ~1–3 GB per hour |
| Max file size | No inherent file size limit in the specification; practical limits depend on storage and the 32-bit atom size field (files over ~4 GB require 64-bit atom sizes, which is widely supported) |
| Year introduced | 2001 |
Advantages
The MP4 file format offers several advantages that make it suitable for common use cases.
- Excellent compatibility across virtually all devices, browsers, and operating systems;
- Efficient lossy compression keeps file sizes manageable without severe quality loss;
- Native streaming support (progressive download and adaptive streaming via fragmented MP4);
- Supports subtitles, chapters, and rich metadata;
- Hardware-accelerated decoding available on almost all modern chipsets, including mobile SoCs.
Limitations
The MP4 file format has certain limitations that may affect its use in specific scenarios.
- Cannot natively store lossless video without using a lossless codec profile (e.g., H.264 lossless), which significantly increases file size. Limited support for uncommon codec combinations compared to MKV. Error recovery in partially corrupted files is weaker than in MKV. No native support for ordered chapters or linked segment files.
Compatibility
MP4 video files are supported by most modern devices, players, and platforms.
- Supported platforms: Windows, macOS, Linux, iOS, Android, Web (all major browsers)
- Supported devices: Smartphones (iOS, Android), smart TVs, web browsers, desktop computers, game consoles (PlayStation, Xbox), digital cameras, drones, action cameras
- Browser support: Yes
- Mobile support: Yes
- Cloud support: Yes
- Streaming support: Yes
Security considerations
Malformed or specially crafted MP4 files have historically exploited vulnerabilities in media parsers (e.g., integer overflow in atom size parsing). Always use up-to-date media libraries (FFmpeg, libavcodec). Treat MP4 files from untrusted sources with caution. DRM-protected MP4 files may silently fail on unsupported players.
License
Open standard (ISO/IEC); some enclosed codecs (H.264, H.265) are patent-encumbered
MP4 (MPEG-4 Part 14) is an international standard multimedia container format defined by ISO/IEC 14496-14. It is designed to store compressed video and audio streams, subtitles, and metadata in a single file. MP4 is not a codec itself — it supports a variety of codecs, most commonly H.264 or H.265 for video and AAC for audio. Thanks to its efficient compression, streaming support, and universal compatibility across browsers, operating systems, mobile devices, and smart TVs, MP4 has become the dominant format for video delivery on the web, social media platforms, and mobile applications.
