Re: HDR -> SDR conversion

Guys, I have added a 'HDR' field to the HEVC Info dialog. This will show "PQ" for HDR10, "HLG" for HLG, and is blank for SDR. I also figured out how to properly detect HDR. There are two ways to signal it: 1) through the transfer_characteristics (16 is PQ, 18 is HLG), and 2) through SEI messages. Pr...

Re: HDR -> SDR conversion

This is interesting: https://www.youtube.com/watch?v=yGSjun9gsbs It shows that, compared to a proper conversion to SDR 709, playing HLG 2020 directly is "OK" but it is much darker and there are color shifts. Probably your clips will perform similarly. Seems to me there is indeed a good justification...

Re: HDR -> SDR conversion

Thank you very much. I will make a proper HLG to SDR filter and see how it compares.

Re: Binaries Update Notification Thread

DGDecNV slipstream 185:

* Added __h2s__ macro to pass HDR to SDR parameters to DGHDRtoSDR(__h2s__). [gonca]

* Fixed regression of 184. H2S settings were being read as the Default Save Project Path. :facepalm:

* Updated the DGIndeNV user manual.

Re: HDR -> SDR conversion

Any chance you could give me a link to one of those transport streams? You can use DGSplit to cut the first 50MB. Only you can decide if it looks "good enough" with no special processing. With one of your streams I can try it both ways and we'll see how they compare.

Re: [RESOLVED] Displaying HDR in DGIndexNV GUI

We can do gonca's idea of adding a template expansion.

Re: Displaying HDR in DGIndexNV GUI

I released this as slipstream 184. Note that the hue parameter is not supported.

Re: Binaries Update Notification Thread

DGDecNV slipstream 184: * Added 'HDR to SDR' under the Video menu. Selection brings up a dialog box that controls a HDR to SDR conversion for display in the DGIndexNV GUI. The display is updated in real-time as the dialog sliders are manipulated. Refer to the DGIndexNV user manual for details. [torm...

Re: Displaying HDR in DGIndexNV GUI

Everything is working except the bonus template stuff. May decide to pass on that. Just have to do some regression testing and then make a slipstream. The sliders have 0.01 resolution. Interestingly, it was not so easy to update the display on a slider change. There was no existing code or entry poi...
