Intel H265 QSV 10-bit Color is Washed Out

[paulrbeers]

Description of problem or question:
Trying to convert 4K H265 Blu-Ray Rip from Full Bitrate to something more manageable for storage. After Conversion using the Intel QSV 10-Bit Encdoer, color is washed out (especially reds). It is as if it is being down-converted to 8bit or something. Size is still UHD.



Steps to reproduce the problem (If Applicable):
I've selected the H265 Intel QSV 10-bit encoder and Main 10 instead of Auto. Quality left on default of 24.



HandBrake version (e.g., 1.0.0):

Nightly build from this month (not at computer to look, but at the oldest, it would be the 3/2, but more than likely sooner.


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Windows 10 with all major updates


HandBrake Activity Log ***required*** (see How-to get an activity log)

Will provide tomorrow. My guess is that I am just missing some setting......

Maybe you can point me to a post about washes out colors using the Intel 10-but encoder? I can only find posts about using x265. Which begs the question if it going to be washed out, why even bother to offer it. Apparently my skills is inferior, your worship.

HDR color video is going to be "washed out" when converted to Standard definition. Using 10 or even 12 bits doesn't fix that.

You didn't post a log so this is just an educated guess. I'm thinking you are keeping the same resolution and just lowering the bitrate. If you are steaming it, the device as well as the player on the device as well as your streaming program has to support HDR. I've found one such connection, thats it. With an HDR file thru plex to my HDR capable OLED, only Plex's LG WebOS app supports the HDR file. If I should play that file anywhere else like plex on my XBOX One on the same tv, I have washed out colors with you. Plex is a play Anywhere solution, but can't properly convert HDR colors on all devices even if the devices support HDR. For now, I recommend keeping an HDR file off an HDR source as well as a 8 bit file off an 8 bit source for proper compatibility.

Correct me if I'm wrong.

What you mean is...... HDR color video is going to be washed out when converted to the 8 bit color space of standard definition. It should (I'm learning) be possible to downconvert the resolution and maintain the hdr color space provided all links in the chain support hdr color. (TV and player application.) it's when they don't support the 10 bit color space that the video is washed out.
