Re: Dolby Vision now possible through MP4 Mux.

The AM8 has the successor chip to the AM6B+ that everybody is boasting about. And like I said in my post, since the AM6B+ is sold almost everywhere in my country and beyond (Europe) the AM8 is actually cheaper with a more direct availability. So I don't necassarily want it because it's 'better' but...

Re: Dolby Vision now possible through MP4 Mux.

Found them! Thank you and also @RESET_9999 for making the files available. I recently got an am6b+ and I'm very satisfied with the device, hope to get another soon. This prompt me to sell my Zidoos Z9X Pro and question whether to keep my Oppo clones. Wasn't aware but realize now that the Ugoos can'...

1- Yes
2- Yes, the Ugoos is more accurate than the ATV and more practical than the x800m2.
3- 100% stable so far and already watched over 10 movies (FEL P7 & P8)
Thank you!

Re: Dolby Vision now possible through MP4 Mux.

@RESET_9999, thank you for the good findings. I have a few questions regarding AM6B+.
1. AM6B+ is CMv4.0 device, right?
2. Can older CMv2.9 TVs benefit from AM6B+ overall?
3. How stable is the experience AM6B+ plus coreelec?
I am wondering if it is worth the update from x800m2 + AppleTV setup.

Re: Dolby Vision now possible through MP4 Mux.

Does the effect ever phase out on higher nits TV? I guess and it depends on how strong the L2 trim is and a 4000nits RPU probably has a bigger effect. I only tested 1000nits RPU and in TV-LED on C2 810nits, Vizio 600nits and Samsung 400nits. I'll check with higher edid in LLDV this weekend. This is...

I tested the AppleTV , Shield and x700, the behavior was the same:

100nits L2 or L8 has an effect if no 600-1000trims exist and the effect is much more pronounced with lower nits TV.

Re: Dolby Vision now possible through MP4 Mux.

The logical leap, if any, is that if only the 100-nit L2 (or L8) trim exists, the engine still uses that to interpolate/interpret and adjust the image for higher-nits and variety of displays. yep, I think that is what's happening. The 100nits trim response is clearly different on my 400 and 800 mon...

Re: Dolby Vision now possible through MP4 Mux.

yes. i know it can do stuff other than diming pictures. my question is why a 1000nits tv need to use trim that target to 100nits display? the trim is created by referencing 100nits target. it does not make sense to use it on a 1000nits tv. I hate to do this, but please see Interpolation . This is l...

Re: Dolby Vision now possible through MP4 Mux.

Well if TV-LEd works the same as LLDV for the target brightness, an internal TV config or an edid of 1000+nits with a 1000nits RPU would make the trims to be ignored which makes less sense to me because then the intentional positive lift would be ignored by brighter TV? I know the trims are ignored...

Re: Dolby Vision now possible through MP4 Mux.

trims are not just for diming the picture to the TV target brightness... They can use the trims to lift the brightness and they do that very often. I literally made a bunch of test file with real content that show exactly that. sorry but It sounds to me that you only read stuff online and you don't...

Re: Dolby Vision now possible through MP4 Mux.

Let's say one makes a content with 1000nits master display and does 100nits trim for SDR. When the content gets playback on a 1000nits display, it will need to use 100nits trim? This does not make sense to me.

It is strange that it only works when L2 100nits is alone without any other trims on the C2.. It might be different on other TVs because as I mentioned, on windows Energy player, the 100nits trim is always used regardless of the other trims.
isn't 100nits trim intended for SDR target display?

Re: Dolby Vision now possible through MP4 Mux.

Not only should we ask Dolby, but also ask LG, Sony, etc. Current behaviors of playback devices and display devices does not make sense to me. Well, unless you are new to this DV thing, we found out quite early that DV is a total mess filled with bugs. yeah. I have been following the thread. maybe ...

Re: Dolby Vision now possible through MP4 Mux.

PS: I just asked Dolby and sent them a bunch of test files about CMV4.0 missing level 8 and L2 trim offset ignored in tv-led. Let see what they say. Thank You! Its super weird that something like this escapes in testing. Is there actually any way to correctly play CMV4.0 files? The internal player ...
