Features Overview
Provides best-in-class performance, compression, and features.
Achieves dramatic performance, encoding 4 or more 1080p streams in realtime on a single consumer-level computer.
Gives the best quality, having the most advanced psychovisual optimizations.
Support features necessary for many different applications, such as television broadcast, Blu-ray low-latency video applications, and web video.
x264 forms the core of many web video services, such as Youtube, Facebook, Vimeo, and Hulu. It is widely used by television broadcasters and ISPs.
