OBS recorded HDR Footage washed out on preview

Hi, I cant seem to get my HDR footage to have proper color. It looks fine on VLC player and OBS preview, But It looks washed out on the davinci preview screen. I can't seem to find a proper turtorial on this that isnt 2 years old and actually works.

Are you using a Decklink and clean feed for your output from resolve to your HDR monitor?

V19 Removed the requirement for the decklink to monitor HDR, but I have not seen anyone discuss actually doing it. So even a year later it seems like pretty uncommon territory?

Resolve generally ignores color space tagging for non-raw clips. So I would not be surprised if you need to tell resolve these are Rec2100 clips. And then as well you want to export to Rec2100.

Telling resolve REC2100 in, 2100 out should give you an unchanged clip. Export that and watch it back and see if that is the case. This will be your first starting place.

I can confirm that it works but I haven't used it much as my deliverables aren't HDR. I guess for the OP the question to begin with is if the monitor is HDR. VLC would auto convert to SDR if not.

In Resolve, it would probably be best to use Resolve Color Managed in HDR Rec.2020 Intermediate mode with the output set to Rec.2020 ST2084 1000nits. (or the one without the nits if you have a reason to not limit it)
In the system prefs of Resolve, use 10bit and use HDR viewers need to be enabled.

That's about it.

My 2022 MacBook Pro 16 with a 1600-nit XDR screen displays Rec.2020 HLG content from an iPhone 15 Pro (HEVC or ProRes) OK in Resolve Studio 19.1.4. That's with RCM enabled, color processing mode = HDR, Output Color Space = HLG, and HDR Mastering for 1,000 nits. Preferences>General was set to "Use Mac display color profiles for viewers" and MacOS System Settings>Displays set to the 1600-bit XDR preset.

I compared it side-by-side to FCP 11.1 on the same machine, and they both looked similar.

I don't think VLC handles HDR properly (at least on MacOS). I tried various VLC settings but nothing worked.

The OP needs to provide the following info:

(1) Windows or Mac, and what version
(2) Hardware details
(3) Monitor type, including make and model
(4) Monitor interconnect, e.g, HDMI, DeckLink, etc.
(5) Full metadata on the HDR video captured by OBS. Use MediaInfo, File>Export, type=text, post that here.
(6) If Mac, what display preset or profile is listed in System Settings>Displays.

Hm yea, forgot to add, my comment is based on being on a Windows machine.
