Umm, OK.

I fixed a small bug in DGIndexNV in the test package, so please re-download and update for testing.

OK, hlg_test.rar is back online so re-download and update DGIndexNV. Have at it!

I've tuned Meari sample to match mpv's output (slightly brighter, but looks better for me)

Ah, good to hear. Thank you.

You probably noticed most of the goodness for PQ is at the top end of the range for white and it is nonlinear. HLG in contrast works much better and feels linear. I'm going to try linearizing the PQ parameter range, it's a GUI issue and a functional one, because we are lacking granularity at the top end.

Gonna tonemap the white parameter space, eh, Rock? Whoop.

Everything released in slipstream 188. Note that the PQ white range is now 1-3000 to give some more granularity at the top end (PQ white range not yet linearized).

Cool!!!!

I have tested my HLG sources, the result is pretty perfect by now.

I will try more samples, this is very exciting!

btw, new 'Enable HDR to SDR' GUI is easy to use ;-)

Hey Rocky, are you sure you are implementing the BT.2390 EETF correctly (see Figure 20)? That's how we should scale for target brightness in PQ, not just change the multiplier for the EOTF. Perhaps that would give a more linear feel. People say I have that linear feel. Meese rule, and, you know, hoomans drool! You know it's true.

Out of curiosity, DGHDRtoSDR uses Reinhard, right?

Where can I find DGHDRtoSDR latest release?

On main site I can download 1.13 only.

Do you plan to integrate the plugin into DGDecodeNV dll?

Fixed the main web page menu for 1.14. Thank you for pointing that out.

Haven't any plans to incorporate it into DGDecodeNV.dll as I want to keep it free.

Re-thinking may be in order.

Now you need storage for that speed (indexing and demuxing)

Is there any way to have chroma 4k 4:2:0 to chroma 1080p 4:4:4 done in CUDA?

It would be nice to have when resizing from DGSource.
