    3 H.265 (also known as HEVC) can offer 50–75% more compression efficiency compared to H.264 video, while retaining the same visual quality. ffmpeg has support for HEVC encoding using the [http://x265.org/ x265 encoder].

     5`libx265` can offer around 25–50% bitrate savings compared to H.264 video encoded with `libx264`, while retaining the same visual quality. These gains will be most pronounced at resolutions of 1080p and higher.
