SDR to HDR (Inverse Tone Mapping)
Hendrik:
Inverse tone mapping is not something JRVR will ever offer, because a simple one-size-fits-all value for something like that is never going to yield any reasonable results. Converting SDR to a reasonable HDR requires a proper mastering step, not setting some value and hoping it comes out ok.
Enabling "direct mapping" would be relatively easy in comparison, but its not something i'm looking to do right this time.
jmone:
Fair enough, as I have no idea how well (or not) a general ITM approach would work for playback. My only experience with ITM is in Resolve and it certainly works well there. Also, if the "direct mapping" method is what Windows is doing, then adding it to JRVR probably not needed.
jmone:
OK... I could leave well enough alone! So here is a test of Inverse Tone Mapping to take SDR to HDR10
- It's the 1min trailer clip from the FHD BD version of Avatar
- Remuxed it to MKV and called it "Avatar SDR.mkv" - this is the "control".
- I then took "Avatar SDR.mkv" into Resolve and rendered it out as HDR10 using their "Inverse DRT for SDR to HDR" and "White point adaptation". It was also scaled to UHD resolution. No grading was done.
(woops made a mistake - will post a new link shortly)
I'd be interested in what people think of the two versions when played back on an HDR display using JRVR.
jmone:
So there are three 1min files now in this folder - you will need to download them and play in MC not in a web browser.
- SDR - The control, just as it was off the BD
- HDR - Luminance Mapping : Inverse Tone Mapping with Luminance Mapping
- HDR - Saturation Preserving : Inverse Tone Mapping with Saturation Preservation
My first sample (which I removed) used Davinci Resolve's own also which would not be available to JRVR.

Anyone had a chance to have a look yet?
