    How to achieve the quality of X264 "2pass slow" with NVENC HEVC? I used the Nvidia Card's picture quality enhancer (sharpening), and the results were fantastic.

    I used the latest version of Staxrip, updated only some files manually.

    Here is the sample file, I cut it out from blu-ray without re-encoding: 1080p@23.97 (600 Mbyte)

    You can download it here (until a week) https://wsi.li/BEAWwFwfV7wQ
    and you can repeat the test too.

    REMEMBER: the file sharing service will delete automatically the files after 7days.

    X264 2pass Slow option with the basic settings ("factory settings") proved to be similar or a bit worse than NVENC HEVC at the same bitrate with its built-in HARDWARE supported picture enhancer/sharpener.

    I encoded both material with 2000 Kbit/sec, and later with 3800 kbit/s (average Youtube bitrate)

    You can download the results here:

    I worked two days for the perfect option of the best settings for the enhancer.

    X265 2pass SLOW (factory settings) WAS humiliated by NVENC h265 with this settings:

    NVENC HEVC (88 Mbyte)

    It is shocking good!!!!!!

    I used only my GPU for image enhancement process and compress, and I achieved the quality of the X265 2pass SLOW.

    So a video card with clever settings can create very very very good quality.
