About MP4 Format

MPEG-4 Video (.mp4)

MP4 (MPEG-4 Part 14) is the world's most widely used video container format, standardized as ISO/IEC 14496-14. MP4 can contain video (H.264, H.265/HEVC, AV1), audio (AAC, MP3, AC-3), subtitles (SRT, ASS), and metadata in a single file. H.264/AVC is the most common video codec in MP4 files, providing excellent quality at reasonable file sizes. MP4 supports 4K, 8K, HDR (HDR10, Dolby Vision), 360° video, and multiple audio tracks. It's the default video format for smartphones, digital cameras, streaming services (YouTube, Netflix), social media platforms, and web browsers. MP4 files are natively playable on virtually every device and operating system without additional software. The format supports fast seeking, progressive download, and adaptive streaming (DASH). For web video, MP4 with H.264 video and AAC audio provides the widest compatibility.
