What is it?
MP4 (MPEG-4 Part 14) - это контейнерный формат, стандартизированный MPEG в 2001 году. Контейнерный формат - это оболочка, которая содержит различные типы данных - обычно видео, закодированное с помощью H.264 или H.265, и аудио, закодированное с помощью AAC, вместе с метаданными, такими как субтитры и маркеры глав.
MP4 является доминирующим видеоформатом в интернете, используемым YouTube, Netflix, Instagram и практически каждым современным устройством. Его сочетание широкой совместимости и отличной компрессии делает его стандартным выбором для распространения видео.

Pros & Cons
Advantages
Plays on every device - phones, TVs, computers, gaming consoles - without conversion.
H.264 and H.265 codecs produce high-quality video at small file sizes.
Supports progressive download and HTTP streaming for smooth online playback.
Stores subtitles, chapters, thumbnails, and multiple audio tracks in one file.
Disadvantages
Quality depends heavily on which codec was used - not all MP4 files are equal.
Standard codecs are lossy. For professional editing workflows, use ProRes or DNxHD.
The more efficient H.265 codec involves licensing fees, limiting some open-source use.
Not ideal for video editing - use intermediate codecs during production, export to MP4 for delivery.
When to Use It
MP4 - правильный выбор для почти всех сценариев распространения и обмена видео.
Video Sharing
YouTube, Vimeo, Instagram, and TikTok all accept and prefer MP4 uploads.
Streaming
Netflix, Amazon Prime, and most streaming platforms distribute content in MP4 containers.
Mobile Video
Smartphones record and play MP4 natively - the default format for recorded video.
Web Embedding
HTML5 video elements support MP4/H.264 natively in all modern browsers.

What is the difference between MP4 and H.264?
MP4 is the container format (the wrapper), while H.264 is the video codec (the compression method). Most MP4 files use H.264 video, but MP4 can also contain H.265, VP9, or other codecs.
Why is my MP4 file so large?
File size depends on video resolution, frame rate, bitrate, and length. Use a video compressor to reduce size - lowering bitrate or resolution significantly reduces file size.
Can I play MP4 on any device?
Yes. MP4 with H.264 video and AAC audio is the most universally compatible video format in existence. If a device plays video, it almost certainly plays MP4.
Is MP4 good for editing?
MP4 works for basic editing, but professional workflows use intermediate formats like ProRes. Re-encoding MP4 multiple times reduces quality. Edit in a lossless format and export to MP4 for delivery.
What is the difference between MP4 and MKV?
Both are container formats, but MKV is open-source and more flexible - supporting more codecs and unlimited audio/subtitle tracks. MP4 has broader device compatibility. MKV is preferred for archiving, MP4 for sharing.
