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: email@example.com (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:
X264 2pass SLOW 2000 Kbps (48 Mbyte)
NVENC HEVC 2000 Kbps (49 Mbyte)
The most important tests:
X264 2pass SLOW 3800 Kbps (88 Mbyte)
NVENC HEVC 3800 Kbps (88 Mbyte)

NVENC HEVC STAXRIP settings:
THE MOST IMPORTANT SETTING of the enhancer:
Results in pictures: Save the images to watch them in full resolution, or copy the "image url" and open them in new tabs.
X264 (3800 kbps)
NVENC HEVC 3800
I worked two days for the perfect option of the best settings for the enhancer.

Is this undeclared advertizing?
X265 2pass SLOW (factory settings) WAS humiliated by NVENC h265 with this settings:
X265 2pass SLOW video (88Mbyte)
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.
