Dolby Vision now possible through MP4 Mux.

[Manixx2020beyound]

you need to use p7 with FEL in order to see differences - because the "problem" occurs when the EL is merged with the BL, and in LLDV this is done by the player/source and it won't be as accurate as tv-led
p5 does not have EL

Ok,
but the Shield is not capable of displaying p7 properly (or any other format than p5), so that comparison between the Shield and the x700 cannot be done (well it wouldn't mean anything).
Also, are you saying that MEL would look identical in player-led and tv-led ?

U would have to do x700 fel LLDV vs x700 fel rgb dv8 to see if that’s true.

I believe I am getting a Python issue while trying to run any of the V0.0.4 Beta files. Please, I truly appreciate any feedback anybody may have:

D:\Dolby_Vision\v0.0.4_BETA>python-3.7.6.amd64\python.exe src\app.py -demux -fel_to_mel


Please, drag and drop here the Single Track Dual Layer HEVC file and press ENTER:
D:\TestFileDV.mkv

You did not specify an output.
The BL.hevc file and the EL_RPU.hevc file will be created in the program folder.
(D:\Dolby_Vision\v0.0.4_BETA)

I believe you have to demux the STDL video track from the mkv into a *.hevc file first using for example tsMuxer (check the video track only and output as demux), and then use that with the bat file.

[AndreasT]

Here is what I'm doing today to convert from FEL to MEL: (using a 4k disc that is mastered as FEL) (e.g. Sum of All Fears)

1. Using MakeMKV 1.15.4, creating an MKV file with main movie and AC3 (e.g. english 5.1) audio of my choosing. "Sum of All Fears.MKV"
2. Making a backup of the same disc. After backup is done, find the .m2ts file representing the main movie. (00067.m2ts)
3. ffmpeg -i path\to\the\00067.m2ts -ss 0 -t 120 -map 0:0 -c copy path\to\00067.m2ts.BL.hevc
4. ffmpeg -i path\to\the\00067.m2ts -ss 0 -t 120 -map 0:1 -c copy path\to\00067.m2ts.EL.hevc
5. Create my BL_EL_RPU.hevc file by running MUX_AND_CONVERT_TO_MEL.bat, specify path\to\00067.m2ts.BL.hevc as my base profile and path\to\00067.m2ts.EL.hevc as my enhanced profile.
6. Open TsMuxeR, add BL_EL_RPU.hevc as my first file, and add "Sum of All Fears.MKV" as my second file. I then create my .ts file (e.g. BL_EL_RPU.ts), delete the old "Sum of All Fears.MKV" file, and rename the BL_EL_RPU.ts file to "Sum of All Fears.MKV"
7. That's it.

I copy the new "Sum of All Fears.MKV" to my plex server, open the Amazon Firestick 4k on my Sony Bravia A8H tv, and watch it. I not only see the movie but have DV picture control options available. I could not see the movie before (just a blank screen) this FEL to MEL conversion.

In steps 3 and 4, you do realize that you are just creating 120 seconds long files right? At least that's what I understood from the original post, the commands are to generate sample files to test the process before applying to a whole movie. Or maybe I misunderstood something.

In step 6, my understanding is that BL_EL_RPU.hevc is supposed to be your complete video track, for the whole movie. After adding both this and your original mkv to tsMuxer do you uncheck the video track before creating the .ts file? The last renaming step I don't understand, why do you do this? Regardless the name I assume the player will interpret it as a TS file.

U would have to do x700 fel LLDV vs x700 fel rgb dv8 to see if that’s true.

How're you getting DV to begin with on Tenet? The UHD Disc is HDR10 only.

Vudu,appletv4k once u own the disc u have a digital 4K copy as well.

The maker's of this film never did a DV grade (only HDR10). That means these streaming providers are doing some sort of conversion. That alone makes this comparison suspect to me (never mind that the comparison is being done on the streamed version rather than full BR disc version).

Hey I’m not going to dispute the legitimacy of the streaming providers doblyvision
That’s why I do comparisons & use uhd as source standard quality wise,
There are some movies that only appeared
In doblyvision on streaming platform eg

163DBA8D-827A-4C4C-ADC4-32A77DFF9D2F.jpeg

This has bin out in doblyvision for years
Official uhd realese in a few weeks
Which I will be able to compare as well.
2012 is another uhd that has bin in doblyvision stream for some time.( soon to be realesed)

[Manixx2020beyound]

Shield plays p7 STDL (mkv or ts) BL and RPU (metadata). It is 100%
FEL is unclear. There is no test patterns to tell for sure.
Probaly new SM UHD Benchmark disk will have one. Will see in Q2'21

But after numerous viewings of "Shuttle scene" in Total Recall I tend to belive Shield just skip FEL and plays BL+RPU only. At least in LLDV mode.
This scene has extremely poorly encoded HDR10 layer and all film grain remains in FEL. So difference BL vs BL+FEL is noticeable.

@ lexyz
What’s the time duration on the shuttle scene?
I would like to try a fel comparison in rgb8 & LLDV for total recall using the x700.

Again, If the studio never released a film in DV then the streaming providers don't actually have a DV version. They are just converting it, so what's the point of comparing something that was never released by the movie studio anyway? And a UHD stream is no comparison to a UHD BR disc/rip.

That’s like saying maldorian,soul web rip dl,
Is a conversion.
5 to 6gigs at that & plays like a uhd some web rips are not far off from the uhd Visually,
bitrate yea, I understand that,
& yes I would like to see the difference in 2012 vs the stream,
Streaming wise there is some great movies on Netflix not on uhd disc, I understand this is about uhd disc, movie shot in 6k 8k 12k cameras then streamed @16mb,14mb,24mb
Looks just as good. Not better yet.
More to your point I have no idea if it’s a conversion vs graded even so I’m still curious about the variety of 1 tittle produce from the masters & eventually it will be all streaming sorry.
A conversion using doblyvision algorithm
Still curious.
There are devices they use in post to view raw hdr in doblyvision using the same algorithm visual as reference.

Could anyone please provide specific instructions for getting Dolby Vision to work on the LG C7 via USB player? I had it working with LG CX using Yosupe's profile 8 conversion tool, now I'm housesitting with a C7 and I can't get anything to work at all including a bunch of random test files I'd downloaded from this thread previously. I also tried the instructions in the very first post but no dice. Anyone have any tips at all? I'm sure I've seen people with success with this TV in previous posts but it's hard to search and find step by step instructions.

I think I have the final webos software version in my region, it's 05.80.55.

LG C7 is able to play mp4 files in dvhe.07.06 (FEL or MEL dual layer DV).
You can play those files from a nas in dlna or from usb.

Here's the method i use to make the mp4 files : https://www.makemkv.com/forum/viewtopic ... 820#p76820

[agneva]

that's a bit unfair, the CX9 can neither dvhe.07.06 nor DTS
