Since I did not find any HLG sources, I determined that just reducing the value for white to 30 gives already nice results, but they tend to look "cold". Your params fix this, and so far I have not found a source where they look bad. So I will use your params as my new defaults until I hit a source where the conversion result looks terrible... And NO, I still do not want to tweak the params separately for each source using preview and a color picker. Especially since I have no way to compare the conversion results with the original. None of my software and hardware players supports HDR, and this won't change in the forseeable future. So thanks for sharing your params, much appreciated... |

You're welcome manolito. I didn't find any HLG source either.
You can compare the output to one of players that do that conversion. I know of mpv or Stax76's mpv.net. Although mpv (.net) tends to give a slightly bluish result, it is good as a guide. @ to anyone who wants to know how I got those params: those parameters were obtaines by adjusting on a source with the help of a color picker. It took me a couple of minutes only to find them. First calibrate the brightest area you find in the whole feature, then calibrate the blacks. Then adjust gamma and roll to get the desired "contrast". Then adjust colors (r, g,b, values). Then re-tweak them all. With practice, it becomes easy.

After a lot more tests I think I know which settings I will use for PQ and HLG sources (until someone else comes up with much better settings)...
My results are in no way scientific, I just took some available sources, converted them to SDR (and SD with REC.601) and watched the results. What really helped me was the LG_Cymatic_Jazz clip which is available at Andy Tather's site as PQ (original LG) and HLG (from Astra satellite test broadcast). Both originate from the same master, and while I do not know how accurately the Astra engineers converted the PQ source to HLG I just assume they did a good job. Download here: https://andytather.net/Panda/VideoGalleryPage.aspx I converted the PQ source using the 44vince44 parameters which resulted in a nice looking SD clip. Then I tried to match this result using the HLG source, and the closest result I could get was using the HDRtoSDR default parameters with the exception of the "white" parameter which needed to be raised to 2000 (from the default of 400). To sum it up my DGHDRtoSDR parameters are as follows: HLG sources: DGHDRtoSDR(mode="hlg", white=2000) PQ sources: DGHDRtoSDR(mode="pq", white=30, gamma=0.5, r=1.05, g=1.06, b=1.08, roll=0.7) The results are here: https://we.tl/t-LhX0RzobLJ Far from perfect I guess, but at least for my needs this is a very good starting point.

Ok it has been accidentally deleted 19 days ago.
@Jkyle, it appears (if I'm not mistaken) it was deleted after your commit here, please confirm there is no reason (read explanation below) ? @Atlantis, it appears JKyle was cleaning up the page, at the exact same time you were editing. When someone edits a Wiki page, and stays long in edit mode, the page does not get refreshed, so they have no idea someone else has made a new addition. I think that's what happened 19 days ago. A sync problem: 2 people editing at the same time... Will be included in next release. |

I have no idea what happened. I didn't mean to delete anything intentionally.
Like @44vince44 said, maybe the document was opened almost at the same time, but it's highly possible that I opened it first and @Atlantis opened it just a little bit later before I finished editing. And I guess I saved it later than @Atlantis. That's why I couldn't see @Atlantis's edit when I opened the document, and his edit was overwritten when I saved it. Hmm... |

I unpacked the same ffmpeg.exe file (27.48 MiB) by running the following command: Code:
upx -d ffmpeg.exe I uploaded it to VirusTotal and here's the scanning result: see this. This false detection issue comes up pretty often. Hmm... Quote:
