    Ah. Unfortunately this seems to result in a file with dropped HDR info:
    Code:
    "NVEncC64.exe" --avsw -i "HDR-HEVC-TEST.ts" -o "HDR-HEVC-TEST.ts.nvencc.hevc.mp4" --output-depth 10 --preset quality --vbrhq 0 --vbr-quality 0 --lookahead 32 --aq --aq-temporal --aq-strength 0 --mv-precision q-pel --profile main10 --level 6 --tier high --chapter-copy --sub-copy --data-copy --audio-copy
    I couldn't find any examples for usage of the option "--dhdr10-info <string>"

    Thank you!

    I had done some small experiments last year with obtaining source settings via ffprobe and mediainfo and re-applying them on a commandline as you kindly showed.

    I was interested to learn more recently that nvencc and ffmpeg, using nvidia's nvenc, also omit things apparently called SEI messages et al which I gather may contain dynamic hdr10 related metadata or something like that.
    I note there is some scheme to obtain that data from the source (not certain, along something along the lines of piping ffmpeg generated raw stream to a metadata extractor and saving the result as a file) and then somehow re-apply that extracted into into the transcoded file. Issues apparently arise if re-sizing or other filtering (perhaps not when more strongly compressing?), so it's not perfect. AFAIK Neither ffmpeg nor nvencc do this automatically, and neither (AFAIK) do they pass through the HDR settings as you showed in the commandline.

    A question could also be, if you can't filter or re-size then why not just copy the source file as-is or copy streams to another container if that's the reason for this (assuming the rest of the HDR metadata comes with a copy).

    I'd hoped to be corrected, and maybe someone could show the sequence of commandlines for the process of dealing with the SEI stuff

    If by pass thru the HDR you mean does it show up in the final output?
    The answer is yes, I usually use MKV container and when I use NVEncC the final result retains the HDR metadata and it makes my tv switch to HDR mode automatically.
    Many, many moons ago I did have to use hdr patcher to implant the metadata but that was long ago in a galaxy far away

    Use the -h option (help) on NVEncC64 (32)
    avs /vpy input is allowed
    Use a script for preprocessing if you wish, best of both worlds
    See options for cropping and resizing

    When I use NVEncC I use a vpy script with all the pre processing and let NVEncC encode, no extra stuff

    Ah, I may try with mkv.
    This log shows it doesn't seem to work for me
    Code:

    Nothing personal but I am going to get a little nasty (in order to help you)
    In your script where is the master display info, please look at my sample
    Why are you using PAL as the format (I realize you are in PAL land) >> UHD like BD has no PAL or NTSC
    enter the proper BT numbers, look at my sample
    Consider using a script

    That's fair.
    Thankyou gonca.
    I had wondered that circa 1 minute before I saw your (good, fair) post.
    Cheers!

    Here is a simple cheat system I use when in doubt
    Create the script with all your preprocessing
    Use a GUI like StaxRip to load your script and start the process
    Copy the command line
    Abort process and study the command line
    I know its tacky but it helps to figure things out

    Thanks !

    I retried without the PAL bit, still no HDR info carried through into output. Oh well.

    I had an old roughy script to parse outputs of ffprobe and mediainfo and use those in commandline settings, and was hoping for something "better" possibly including processing of "SEI" type stuff which I'd seen a few posts about including over on ncencc's github issues list.

    OK, that's it from me.

    Did you include (corrected for your clip)
    --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15 635, 16450)L(10000000,1)" --colormatrix bt2020nc --colorprim bt2020 --transfer smpte2084 --max-cll "1351,384"
    I know it works, I did over 100 UHD discs with NVEncC
    Try loading a script into StaxRip and see the command line it generates

    apologies, I had cross-wires with you, ... I was testing to see if HDR metadata "auto passthrough" was a thing, which it isn't.
    manual command-line options/values are doable as you very correctly point out.

    I still prefer to generate my own scripts and using that as input, so if I have to enter HDR metadata manually, so be it.
    Not the end of the world

    I'm with you on that, especially given the current state of play.

    Ah, to summarise the settings changes from various posts:

    1. just came across this: https://forum.doom9.org/showthread.php?p=1709584#post1709584
    madVR Options Explained

    2. Ensured 64-bit registration of the madVR .ax (for win10x64)

    3. Changed these madVR options:
    Chroma Scaling to Bilinear (processing done by GPU Texture Units)
    Image Downscaling to DXVA2 (processing done by GPU video logic)
    Image Upscaling to DXVA2
    under devices, properties, set "the native display bitdepth is" to "10 bit (or higher)"
    under devices, hdr, set "hdr" to "passthrough HDR to display"
    under devices, hdr, ensure ticked checkbox "send HDR metadata to the display"
    and the OSD changed to look like this:

    4. Changed these Win10x64 options:
    Display, Play HDR games and apps to On
    Display, Windows HD Colour Settings, Play HDR games and apps to On
    Display, Windows HD Colour Settings, Stream HDR Video to On

    And the resulting on-screen display changed to look like in this post:

    bye.

    Where was it ?
    Were you taking about a madvr setting or a Win10 setting ?
    Thanks

    Ah.

    How does this appear to you (watch all 2 mins) https://4kmedia.org/lg-chess-hdr-demo/
    (control J in MPC-HC to see stats including HDR and 10-bit)

    Or even this in Chrome browser https://www.youtube.com/watch?v=2RIDhA9c8qw
    (right click in the video area and choose stats for nerds)

    Both appear BEAUTIFUL on my rig, so perhaps consider double-checking your madvr and Win10 options ?

    ( hint https://forum.videohelp.com/threads/394116-New-PC-pls-recommend-me-a-media-player-etc-...ck#post2558325 and https://forum.doom9.org/showthread.php?p=1709584#post1709584 )

    Can you please try the .mp4 from https://4kmedia.org/lg-chess-hdr-demo/ ?

    It is a known-good source. Particularly, the opening scene with the princess, does it get very colourful ?

    A screenshot would be great.

    Hmmm, clicking on the "download file" button and then the "download anyway" button works every time here.

    Pls try again, so we know what a known good source looks like on your rig.

    Also, your madVR and Windows settings also reflect those in the attachment ?

    Can't explain that, it works with a known good source.

    Try some other known good sources downloadable at that website, just to check.

    Given that known good sources work OK, suspect perhaps your movies may be flagged as encoded 10-bit however during the "capture" process (whatever it was) the colours may have undergone an "unfortunate" conversion resulting in what you see when playing those movies. Can only really tell by playing some more known good sources so as to prove it is related to the source rather than the software.

    Sorry to hijack this thread, but I am trying to get HDR content to play with MadVR and whenever I try to play HDR content, it will only play in windowed mode (fullscreen turns the screen black) I can get the video to show in full screen if I right click to bring up the right click menu in MPC-BE but closing the menu makes the screen go dark again.

    Screen is 49" Samsung CRG90 it automatically switches to HDR mode when a HDR video file is opened and MadVR renderer is selected. If I set Windows HDR to on first then the picture is gray/washed out.. it looks better if MadVR auto switches the screen displayport to HDR mode so I leave the Windows setting alone.

    I did this:

    1. Ensured 64-bit registration of the madVR .ax (for win10x64)

    2. Changed these madVR options:
    Chroma Scaling to Bilinear (processing done by GPU Texture Units)
    Image Downscaling to DXVA2 (processing done by GPU video logic)
    Image Upscaling to DXVA2
    under devices, properties, set "the native display bitdepth is" to "10 bit (or higher)" (I tried 8-bit too which is what my screen switches to)
    under devices, hdr, set "hdr" to "passthrough HDR to display"
    under devices, hdr, ensure ticked checkbox "send HDR metadata to the display"
