Although P5 can’t do 10,000nits.
why not? there are a couple of HDR10 movies on streaming services that have maxcll of 10 000nits.
why would it be different in p5 DV ?

HDR10 is max 4000 nits

https://www.rtings.com/tv/learn/hdr10-vs-dolby-vision
not true. HDR10 is max 10 000nits

spears and munsil:
Maximum Content Light Level : 10000 cd/m2
Maximum Frame-Average Light Level : 1676 cd/m2


Mad max (one of the first HDR movie):

Maximum Content Light Level : 9918 cd/m2
Maximum Frame-Average Light Level : 3241 cd/m2

there are also a lot of movies with maxcll higher than the mastering display luminance. (maxcll is not always accurate though).
there is also Blade runner 2049 that was mastered on a 10k nits monitor but only have a maxcll of 181 nits

mmm... I just got my Ugoos and very bad news: there's no 23.976 mode, only 24hz.
99% of movies are 23.976, so this device is useless. I hope I can return it...

FYI, playing 23.976 content in 24hz = dropped/repeated frames every 42seconds.

Trying 1 last time
Set timer came back tv was off lol
Strange thing doe if I force LLDV from the device it plays the whole movie but NO fel
Trying when it triggers naturally is the issuse .
But I’ll keep trying seeing that the ugoos is no go.
Sonyx700 or streaming platform still the best option for fel movies.

this is not UGOOS related but I just learned that if you remux DV to bluray folder structure with tsMuxer and you put the files in the root of an USB drive, the Sony x700 is able to play it in dolby vision with chapters, working FF RW for long movies and no more green screen bug when you stop playback.

Wow, that's fantastic! I need to try that too! BTW, I see you got a Ugoos delivered. Are you able to confirm that it in fact supports the FEL titles and plays it correctly?

It's definitely processing the FEL as @mattmarsden confirmed. The Power Rangers ending credits is bright white and because I fast-forwarded, it kind of froze and it caused ghosting. I clearly saw the grey HDR10 BL and the EL on top of it.
At first, playback was not very stable but now Power rangers is playing for an hour and everything looks stable.

I'll have a deeper look at the colors on my OLED tomorrow. it looks very promising.

What if the movie is already in bdmv structure, then which files do we put in tsmuxer?
you drag and drop the correct mpls file into tsmuxer and create a new bluray structure.
