thanks. so how do you convert the png file to SDR ? ffmpeg as well or madvr ? can you share your process ?
So just open the png in MPC-BE/HC/madVR. it needs ''transfer=hdr'' in the filename.
Can confirm that, no more Dual track/dual layer mp4 files with CX.
Ouch, i thougth the lack of Dolby Vision support could be offset with Dynamic Tonemmaping and it seems its still garbage on CX according to HDTVTest:
B6 are (or were if firmaware did not change that ) play Dual track/dual layer DV MP4 files, so he betters keeps just using the Dolby muxer tool, profile 7, and get a Dual track/dual layer MP4 DV file.Roberespa wrote: Sat Dec 12, 2020 4:24 pm-Hello:Maikel777 wrote: Sat Dec 12, 2020 3:55 pm I also have a TV
LG OLED55B6V.
For the movie The Lord of the Rings.
Which Dolby Vision profile is best suited for my TV? 5, 7, 8 or 8.1
Thanks in advance.
I have found this information:
Profile 5 single layer with exclusive support for Dolby Vision
Single layer 8.1 profile with HDR10 + Dolby Vision compatibility
Profile 8.2 single layer with SDR compatibility
From what i can read Profile 8.1 would be the best as it has HDR10 + Dolby Vision.
But I am a newbie at this.
If someone clears it up.
I would be very grateful, it is also of my interest since I have the same television.
''transfer=hdr'' is only to tell madVR: hey this file is in PQ.Manixx2020beyound wrote: Wed Dec 16, 2020 2:33 pm

yeah, your post was a bit unclear, but this one cleared it up. Thanks.RESET_9999 wrote: Thu Dec 17, 2020 4:06 pm????
I just answered that one post above.. that parameter is only for madVR...
if you want SDR screenshots, no need of FFmpeg. just tone map your HDR video straight in madvr.
problem is that player-led LLDV is often less accurate than tv-led full STD DVManixx2020beyound wrote: Thu Dec 17, 2020 10:57 pm This is an interesting read
According to this article dv-rgb8 is the old dv & LLDV is now mandatory on all doblyvision regular dv is not required
LLDV has it own profile as well.

the problem is the approach, in player-led LLDV the TV/sink must pass over all calibration parameters and current settings/values (whatever can be passed via HDMI, EDID etc), and based off that the player must decode the Dolby stream accordingly.DaMacFunkin wrote: Fri Dec 18, 2020 9:05 am Blame Sony.
Dolby set out with good intentions and now hardware manufacturers are calling the shots.
So the dolby vision files created using the method in the OP can't be played using the tv internal media player anymore? What is the alternative?Wanderlust3K wrote: Wed Dec 16, 2020 3:32 pmCan confirm that, no more Dual track/dual layer mp4 files with CX.
Totally agree, had this argument with many a LLDV evangelist, with the Oppo clone you can switch between Tv led and player led, there’s is a difference, on some content it is very noticeable.pete19 wrote: Fri Dec 18, 2020 9:38 amthe problem is the approach, in player-led LLDV the TV/sink must pass over all calibration parameters and current settings/values (whatever can be passed via HDMI, EDID etc), and based off that the player must decode the Dolby stream accordingly.DaMacFunkin wrote: Fri Dec 18, 2020 9:05 am Blame Sony.

This will most likely never be as accurate as decoding full tv-led DV in the TV hardware itself with all of those parameters plus additional data that cannot or wasn't transmitted...
in a perfect world it is, but practical tests have often shown the difference
