Download x264 Video Codec for Windows 7, 8, 10, 11 - A free software library and application for encoding video streams into the H.264/MPEG-4 AVC compression format
x264 Video Codec 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.
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.
