HDR on SDR TV, MadVR default settings

(1/2) > >>

flac.rules:
Are the MadVR-settings for red october HQ reasonable for watching HDR content on a SDR display? (thinking about tonemapping and such), or should I change any of the MadVR-settings?

BryanC:
I think that new tonemapping code is only available in the beta madVR versions. I would love to see this as a setting as well. There's been a lot of good work recently on creating HQ tonemapping curves and any of the popular options would be good candidates for ROHQ HDR->SDR mode. I think madVR does a pretty good job of HDR detection but maybe it should also be possible to create a Zone based on an [HDR} tag or automatically based on bitdepth (I'm not sure if all 10-bit sources are HDR or not).

My set is technically HDR but it does such a poor job of rendering it I just leave it off. As more and more of my sources are 10-bit HDR, it would be great to have the tonemapping functions built into MC's madVR.

Elvis, technically you can accomplish this right now by using a beta madVR version as a custom filter, using a madVR profile rule to separate your HDR and non-HDR content:

--- Code: ---if (HDR==true) and (bitdepth==10) "HDR"
else "SDR"
--- End code ---

...and then entering your preferred tonemapping curve/settings for the HDR profile.

You'll probably need to modify your other profile quality rules too because tonemapping pegs my GPU.

I'm using the latest madVR Beta and the Tone Mapping from HDR --> SDR looks fantastic on a variety of UHD displays (including a 125" JVC PJ, 65" Sony OLED, and even a 43" LCD I'm using as my PC Monitor).  Couple of things to note:
- It's a beta.  It's not part of MC and I'm sure the JR'ers will explain it is not supported
- If you wanted to "play", then head over to AVS - https://www.avsforum.com/forum/24-digital-hi-end-projectors-3-000-usd-msrp/2954506-improving-madvr-hdr-sdr-mapping-projector-281.html to get the latest beta (search backwards from the end of the thread)
- It's a beta and alot of options are fully expanded and not yet settled.  You are going to need to read and understand what the thread is on about.  It is not a support thread either.  You need to be pretty self sufficient.
- If you are still keen, then all you need to do is download the correct beta version (32 or 64 bit) and overwrite the madVR files in "C:\Users\[USERNAME]\AppData\Roaming\J River\Media Center 26\Plugins\madvr".  You may want to make a copy of this folder first if you have made any madVR changes and want to roll-back.... otherwise just delete the madvr folder and MC will download the latest supported version.

Other option is just to wait.  I'm sure Hendrik is all over this, and will look at upgrading the version of madVR and the correct point in time.

MadVR shipped with MC does have tone mapping hdr to sdr ... not much options to tweak it except target nits

Sure about this? I tried running HDR in MC vs VLC, and the difference is dramatic.
