x265 HEVC Encoder / H.265 Video Codec

x265 is a H.265 / HEVC video encoder application library, designed to encode video or images into an H.265 / HEVC encoded bitstream.

x265 Project Goals

x265 best overall HEVC encoding efficiency

x265 demonstrates best overall HEVC encoding efficiency in Moscow State University’s Codec Comparison

  • Develop the best HEVC (H.265) video encoder in the world
    – Offer the highest possible quality at any given bit rate
    – Offer the lowest possible bit rate for a given quality level
  • Deliver the world’s fastest and most computationally efficient HEVC encoder
    – Highest encoding speed on any hardware configuration
    – Highest visual quality, whether you are doing high quality offline encoding or high speed real-time encoding
  • Deliver industry-leading HEVC codec features, supporting the full HEVC standard including range extensions
  • Achieve wide adoption from the open source community, leading web video services, broadcast encoder developers, independent software developers, video hardware and software developers, device OEMs, semiconductor manufacturers and academics.
  • Provide the best possible support to developers, licensees and adopters

Try it

  • The x265 Encoder application combines a user-friendly interface with the x265 encoder library, making it easy for anyone to convert MP4 files to HEVC.
