Your video is missing the framerate at the bitstream level. You can fix it in 9-2
This used to be the case with all the Apple WEB-DL, but now, all the reputable groups fix it.

Hi RESET_9999 ,
Karate Kid Legends has got both DV8 and HDR10+
I want to remove HDR10+ and use your scripts workflow 2-2
Everyhting was done and the resulting file is "Karate Kid Legends_HDR10plus_removed". But why his framerate is 25.000 fps whilst the original movie is 23.976 fps?
Thanks

@RESET_9999
Usually, with the full uhd bluray disc (bdmv folder), I just find the main playlist with BDInfo, put it in mkvtoolnix and convert it to mkv to watch the movie on the ugoos, but now if I want to watch Special Features/Bonus Contents as well, what should I do?

I dont know...

But FYI, mkvtoolnix can find the correct playlist by itself, no need for bdinfo.

oh cool thanks for letting me know.

Btw do you have the cmv4.0 rpu for Dune Prophecy? Can't find P5 version anywhere to do the transfer, only P8.

Do these plots look normal (it's Dune Prophecy)? :

bluray's madvr plot:

web's madvr plot:

web's DoVi plot:

What is the point of generating DoVi plot if it always looks different from the other two?

The colorist can choose a tuning parameter that controls the aggressiveness of Dolby Vision tone mapping. Lower values result in less tone mapping and a brighter image, while higher values apply more aggressive tone mapping, resulting in a darker image.

You've uploaded the web dovi plot twice.

If you are wondering why the madvr plot looks different to the Dovi plot, it's because DV (& HDR10+) metadata are meant to be used during playback for tone mapping. They don't always represent the actual brightness (1:1) of the shots. madmeasureHDR.exe will always be more representative of the actual brightness.
