Do you suggest me to search for a proof for your statement? Really?
I would rather not spend time on this misconception.

The EL is a 10-bit video bitstream that carries the residual between the source and the BL and the “dynamic” metadata for DV. An enhancement layer that carries a residual signal is = 0 (zero), that is, the decoder does not need to process the residual signal, is called minimum enhancement layer (MEL). If the residual signal is > 0, it is called full enhancement layer (FEL)Pacer wrote: ↑Mon Dec 21, 2020 5:28 pmHello everyone,
first I wanted to say a big THANK YOU to everyone so dedicated to get the DV playback riddle solved, first of all to yusesope, whose tool I've tried to use.
I've just had one UDH Bluray Disc (MI: Fallout), which I tried to get to run in DV after ripping it. With the help of yusesope's tool I was able to create an mp4 file which my LG OLED65GX9LA liked to play. I used the software and procedure described on p199 in this forum:
- ffmpeg to demux from BD m2ts file
- MUX_AND_CONVERT_TO_PROFILE_81.bat
- mp4muxer to get an .mp4 file
The file triggered DV on my LG TV, but I am not sure if it displayed the content correctly. That's why I would like to ask you more experienced people to take a look at my photo comparison (DSLR in manual mode). From left to right you see:
- MKV ripped with 1.15.3 from BD disc, played on my HiMedia Q10 Pro (which plays the file only in HDR10)
- same file, but played from my LG OLED65GX9LA with internal player via DLNA (which also plays it in HDR10)
- mp4-File created with the above procedure, played from my LG's internal player with active DV

To me, the colors look quite different compared to the HDR10 variants of the movie. I do not have a hardware BD-UHD player to see how the movie would look like when played from there :-/
What are your thoughts on this?
In my expectation the colors should not differ between HDR10 and DV, right?
you don't seriously think anybody here will spend more time educating about something that you've not done your research for.

but you can always "believe" what you want
like I said, this is years old. You spread misinformation, I'm sure not on purpose.
two main things about DV that are the reasons it is the premiere HDR format:
(1) ability to fully re-create the 12bit 422 master at home in FEL dual layer releases
(2) dynamic metadata
No where is there a mention that the output video is actually 12 bit 422.
first off, nobody said 420 is "wrong" - that is your wording. 420 simply has less color resolution, hence 422 is more desirable.
you make it sound like that "explains" a 12bit 420 final output. no, the metadata allows to reconstruct the full 12bit 422 master, which is why it is a 12bit 422 signal.
you want more ? here is an encore...DaMacFunkin wrote: ↑Wed Dec 23, 2020 6:58 amI’m off to get some popcorn for round 2, this is freakin’ awesome
Interesting.

MI Fallout is a FEL Dolby Vision movie. (BL + EL (>0) + RPU)
Making DV files in single layer profile works only with MEL (EL=0).
The only correct method to have dual layers files (or dual tracks of single layer) is with mp4muxer with Dolby Vision in profile 7.
From network? The oppo and that's it.MastaG wrote: ↑Wed Dec 23, 2020 9:12 amSo which players are capable of playing FEL remuxes from network sources (Plex/Emby/SMB), e.g. the full deal retaining the 12bit 4000nits final picture like when playing the original disc?
e.g. remuxed into a TS or MKV container so I can add a high def audio track?
Oppo with (free) Russian firmware hack can do all of that. And you can mux to m2ts or BDMV folder structure and it'll play it (and keep HD audio). As long as you don't trim the movie, tsmuxer creates a perfect DV mux.MastaG wrote: ↑Wed Dec 23, 2020 9:12 amSo which players are capable of playing FEL remuxes from network sources (Plex/Emby/SMB), e.g. the full deal retaining the 12bit 4000nits final picture like when playing the original disc?

If instead I choose to play my files with the profiles dvhe.05 and dvhe.08 ..., the hardware decoder will try to process the Base Layer (BL) and to improve it through RPU metadata by discarding the EL layer.
however, the Base Layer is non-standard (it has a different color space than the IPTPQc2/IPT one) as extracted from a Bluray disk.
It should appear better than an HDR stream (since metadata is dynamic and non-static) but will not reach its maximum splendor due to the lack of data contained in the EL layer.
The lack of this information, however, could lead, in some cases, to evident chromatic aberrations.
