## Definition

H.264 (also called AVC) is the most widely used video compression codec, delivering good quality at relatively low bitrates with near-universal device and platform compatibility.

## Extended Definition

H.264 (Advanced Video Coding) was standardized in 2003 and remains the default codec for web video, streaming, and social media uploads. It balances compression efficiency with decoding speed, making it playable on virtually every device from smartphones to smart TVs. YouTube, TikTok, Instagram, and all major platforms accept H.264 encoded MP4 files. The codec supports resolutions up to 8K and frame rates up to 300fps. While newer codecs like H.265 (HEVC) and AV1 offer better compression ratios, H.264 remains the safest choice for maximum compatibility. BlitzReels exports video using H.264 by default for universal playback support.
