Overview
x264 Video Codec 64-bit is a free software library and application for encoding video streams into the H.264/MPEG-4 AVC compression format and is released under the terms of the GNU GPL.
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 Video Codec 64-bit forms the core of many web video services, such as Youtube, Facebook, Vimeo, and Hulu. It is widely used by television broadcasters and ISPs.
