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...

Regarding show2 offsets, yes, that is a current limitation. If you make a strong argument, I can try to change it, but it would be low priority.
Ah, now I understand why it behaves that way. No, this is no issue. There's no need for any changes. :)

Re: Indexing Issue

Umm, I think I know where I messed up the overlay. I renamed the x64 dgindex .exe file so that it's easier for me to use in commandline (since both x86 and x64 version have the same file name.) I changed the name back to its original and now the overlay info works perfectly. I am so sorry for the tr...

Re: Indexing Issue

Thank you.

Here's the info:
- 1st: same path in dgi file
- 2nd: verBufferSize: 0
- 3rd -> 5th: nothing happened. It just repeated what shown in 1st and 2nd.
