Re: HDR -> SDR tonemapping

No rush, hehe. Btw, I thought you were going to say "... after the World cup match." :D

Re: HDR -> SDR tonemapping

What do y'all think of this result? If you like it I'll make a release. I think it looks really good. But, please allow me to be a bit nitpicking :) There seems to be little artifact exists along the contour if you look closely (literally). Well, either that, or the saturation makes me think it's a...

@dmcs

Is this sample known to be Dolby Vision?
I'm not sure what you meant. m2ts has Dolby Vision metadata. mkv sample file doesn't.
Here's the full mediainfo of the m2ts file.

Re: HDR -> SDR tonemapping

@dmcs Can you tell me how that bigger sample came to be? Is it from a UHD bluray? How was it processed? If it is from a UHD bluray, it would be much better for me to get the m2ts file. One problem with the mkv is that we don't know for sure all the metadata is being preserved. Yeah, I used MKVToolN...

Re: HDR -> SDR tonemapping

Hi, I hope a 3 minute sample would suffice. Let me know. https://mega.nz/#!oYNFQaTS!fruexcgJYX_BtlfXzTnDEhjgibgdHoqhT0762v_l7Kg I think I've jumped into the "overblown" conclusion too early. My apology. Here are some screenshots that I took, using Mobius, with light=250 and 500 respectively (other p...

Re: HDR -> SDR tonemapping

Lowering gamma does help with DGHDRtoSDR to restore the darks for that scene, but I assume when you say "brings back the issue", you mean the clipping of the bright spot, such that it shows a clear outline of a brighter area. Is that correct? If so, I can implement a compression style gamut mapping...

Re: HDR -> SDR tonemapping

Hi, I am having an issue with highlight being overblown in this particular scene. If I set light=500, it seems to alleviate the problem, although not entirely. However, every thing else will be too dark. And adjusting gamma brings back the issue. HDR No tonemapping https://malzo.com/i/2018/07/02/xBG...
