Re: Dolby Vision now possible through MP4 Mux.

I'm referring to whatever model @dmdreview tested in his video. You can ask him, I don't have this device. I looked closer and he says in the video description (not in the video itself) that it is the Homatics Box R 4K Plus. That's the latest Amlogic S905X4-K that's being used in all the current SE...

homatics etc..), they are completely broken.
Is the Homatics Box R 4K Plus definitely one of these that is completely broken when the MDL >1000-nits?
If not, which Homatics device are you referring to?
Asking because I thought the Homatics S905X4-K devices were CMv4 devices.

Re: Dolby Vision now possible through MP4 Mux.

This Dolby Vision "affair" is becoming more and more complicated and difficult for us common people. Yeah feels like we need a completely new thread with more organized instructions. Do we even consistently get better image with dolby vision compared to hdr10 at this point? I honestly hav...

Re: Dolby Vision now possible through MP4 Mux.

because the C2 original DV configuration was broken and brightened everything. When they fixed the C2, my C8 was already sold so I couldn't test that anymore. That part answers my question. I was wondering if the C2 was ever fixed and it sounds like you're saying that it was. I have a C8, C9, and C...

Re: Dolby Vision now possible through MP4 Mux.

I literally gave my latest update on different rpu responses on players like 3 posts ago... That's why I went searching for that old post... the correlation wasn't clear to me. I'll re-read though and try to understand. Thanks for all your research; I'm just nowhere near your level of understanding...

Re: Dolby Vision now possible through MP4 Mux.

I think I found a huge bug on the x700/ x800m2 / C2, even worse than the red push or the lack of FEL support :( The L1 brightness changes are totally different than the C2 internal plex and the Shield(which have newer DV engine) but L2 looks exactly the same on all the devices. By different I mean ...

Re: Dolby Vision now possible through MP4 Mux.

yes, I always remove cmv4.0 when it doesnt have L8 but has proper L2 trims. The bluray Wierd Science Is a good example. It's two times brighter in cmv4.0 because the very strong L2 trims are not used. https://i.ibb.co/7XfqgKg/Weird-Science-1985-BD-MEL-Do-Vi-L2-PLOT-600nits-trim.png https://i.ibb.co...

Re: Dolby Vision now possible through MP4 Mux.

Now the problem is that most of the CMv4.0 movies only have a 100nits L8 trim pass which is obviously not used in DV playback but they do have proper L2 trims that are ignored on cmv4.0 devices (shield/firestick/appletv/internal tv ). So you get inferior quality on those devices unless you remove t...

i dont know, try to remove or duplicate the last frame in 2-1-1
The problem is that the BL is 203759 frames and the EL & RPU are both only 203758 frames. I can't do that with 2-1-1 though since it'll only effect the RPU, right? Any ideas on how to remove 1 frame just from the BL in the AVS?

Re: Dolby Vision now possible through MP4 Mux.

you can use the ''trim'' function in avisynth something like that: bl2 = Trim(bl, 0, -206370) el2 = Trim(el, 0, -206370) I'm getting the error message "DoViBaker: Clip length does not match length indicated by RPU file" in StaxRip after using 7-1. It seems like the EL & RPU are 1 fram...

I'm getting the error message "DoViBaker: Clip length does not match length indicated by RPU file" in StaxRip after using 7-1. It seems like the EL & RPU are 1 frame shorter at the end than the BL. How can I fix this?

Re: Dolby Vision now possible through MP4 Mux.

I haven't tested Apple/Amazon/Google devices with a capture card, but I have hooked them all up to a calibrated screen, compared, and the differences were significant. They all appeared to be doing their own tone mapping. I haven't tested this in a long time though so it's possible some/all have im...

Re: Dolby Vision now possible through MP4 Mux.

Does anyone know why more playback devices aren't capable of utilizing the 100-nit L2 trim for playback on SDR devices? I've noticed that Apple, Google, and Amazon devices don't use the 100-nit L2 trim for playback on an SDR device even though all of them are Dolby Vision compatible. I'm following ...
