Dolby Vision now possible through MP4 Mux.

Tested the mp4 version:
On CX it works perfectly
On x700 L2 trim_offset does not work.

L1 works well in CX
Much less well in x700 (you can barely see the changes).
Same results in x800m2

[RESET_9999]

You also mentioned FEL, what about it? I guess you mean internal players, just checked the Spartacus-Gladiator mix FEL on the Oppo and it works fine.

Fel works but I meant I can't use my x800m2 anymore now that I know about this bug. L1 has a much bigger impact on the picture quality than FEL.
So for me, it will be the internal plex player of my C2 for everything. I thought maybe I can live with the red push so I gave a try to the Shield and checked the Dr. Sleep little girl scene and Oh boy, because the colors are a lot more saturated on the C2 than the C8, the red push is even more noticeable and it looked horrible.

Thanks for testing, but does the L1 works on Sony+C1?

Hmm, I'm not happy either about L1. Do you know if it is used frequently on UHD BD discs?
And yes, Shiled is only usable with profile 5 mkv, nothing else.

o yeah, L1 is mandatory for DV. L2 trims are optional and a lot of movies have only a 600nits trim pass and I'm pretty sure our 900nits TVs are not getting it so in this case it totally rely only on L1.
plus L2 is only really useful when the content is brighter than your TV capabilities.

sure, here are videos showing exactly what I'm talking about. There's clearly something wrong.
I'm curious about your firestick...

Both of the FireTV sticks are the same.
Only "L1 higher contrast" does not clip like the C2 internal player, "L1 lower contrast" is just dimming the sky.

It's not really clear which is correct behaviour.
As the C2 player makes it clip out detail while external devices seem to tone map to a minimum peak limit.
It would have to be tested with a higher and lower brightness clip, to see if it reacts differently.

The Sony still seems to not work for "L1 lower contrast" either, but the sticks do.

Is the sky clipping all the time with the Sony? It looks like that in the video.
The sticks never clip.

I see a slight change for every L1 but it's almost unnoticeable if I'm not 1 feet close to the TV. I was more focussed on the brightness changes but IIRCC both sony dont clip at all.
I think the C2 internal player clip more than the C8 internal player though.

I dont know about the firestick but In my mind, there's no doubt the x800/x700/oppo are wrong. It's quite obvious in the madvr out sync version of SM clip i did.
theres a lot more clipping on the x800 than with the C2 internal player.

Yeah that doesn't look right at all.

I confirm your findings. there is a lot more clipping on the x700 than on CX internal player.

[RESET_9999]

I confirm your findings. there is a lot more clipping on the x700 than on C1 internal player.

thanks so it's not only a C2 issue and it very much looks like an issue with V2.9 vs v4.0 since the shield happens to have the newer DV engine too and behave properly.

Is this only an issue with player-led Dolby Vision? Can the C2 perform TV-led Dolby Vision while still using the x700 to avoid the issues with L1?

those video are TV-led

it's also an issue with LLDV and it's actually a lot worse because not even L2 works with player-led TV.

My Oppo was set to TV-led specifically.

yes

dolby vision is great on my lg oled e8 but i don t see subtitles ?

subtitles must be external SRT and filename the same as the TS.
example:
Movie.Name.ts
Movie.Name.ENG.FORCED.srt

I dont know about the native LG player but it works in PLEX

[sofakng]

Can anybody with an oppo (or clone) test this?

Does it also have the bug?
