this makes DVDFab with DV SL, can´t be set.

the MEL movies can also be re-encoded. Thank's to @quietvoid rpu extractor.
did you try with profile 8 ?

How can I create Profile 8 with reencoded FEL ?

Of course you can´t see any difference between a empty (M)EL and no EL.

Private Ryan´s FEL is pumping when you look only the FEL on Media Player Classic, looks very strange
The quality is bad + brightness pumping if you watch it without FEL. The FEL is necassary.
I tried to watch, but after 20min i switched to HDR10.

Today I could convince myself from the real DV Version of Ryan its very nice.

* Tutorial on how to convert an .iso movie with HDR10 and Dolby Vision to .m2ts *

* This tutorial is primarily intended for all novice users who don't want to read all these forum pages. you will get a good result. Without having to do a lot of tests and trials until you get it. *

(This is something that I miss a lot, that from minute one you start reading this new and very tedious thing. So now that I know how to do it; so that you don't spend hours and hours I have decided to do my personal tutorial with the aim of help them.)

The first thing you need is to have all these programs updated in their latest version, otherwise it will not work !:

MakeMKV
tsMuxeR:
on page 259 the user "RESET_9999" offers us the link to the latest versions of tsMuxeR.
ffmpeg
Unzip this program to C: \ and rename the folder (call it) ffmpeg | In Windows environment variables (you can search for it in search box) open it
Give Environment Variables, double click on Patch, click again and type the path C: \ ffmpeg \ bin OK, OK and OK. This tells the CMD that you know the ffmpeg commands for easier access.

Once these programs are installed or updated:

1º Use MakeMKV open the UHD iso with Dolby Vision and extract the video track. (Check only the video track, uncheck all other audio subtitles, etc.) In short uncheck everything so that you only save the video track.
2º Open the "cmd" (Command Prompt) as administrator and write> ffmpeg -i Rings.mkv -map 0: 0 -c copy T: \ BL_EL_RPU.hevc * With this I manage to merge the 2 layers in a single file with the possibility to disjoin *
Rings.mkv is the name of the mkv that contains only the video obtained from the MakeMKV program, I write the correct name in my case, I change the name to make it easier for me. T: \ (I'm telling you to save the result in that directory.) BL_EL_RPU.hevc is the name that the final file should have.

3º Use tsMuxeR and open "BL_EL_RPU.hevc" To put the audios and subtitles that you mount in a virtual unit, the FULL-UHD Dolby Vision.iso adds 00073.m2ts unchecks the two video tracks (only adds the audio tracks and subtitles) or previously with tsMuxeR you make a DEMUX to simply add the audio tracks and subtitles to the "BL_EL_RPU.hevc" and give it to create a .ts or .m2ts video file (I recommend .m2ts because it is the purest).
and ready.

Step 1 creates a video file with HDR10 and Dolby Vison but most televisions do not open it, so you have to do step 2 and 3 that I mention.
I hope it will be very helpful to new users. I spent many hours reading and testing. It gave me a lot of mistakes. But with this method everything works perfectly.

You will get a .m2ts or .ts file with HDR10 and Dolby Vision valid for the vast majority of televisions.

Hello from Spain Rober.
Please can you tell me how to do if I have two disc for example of hobbx or LOTR???
How I can merge the two disk to do your tutorial?

you have to use yusesope tools or demux your dvdfab mp4 file and then remux with the mp4muxer to profile 8.

How can I create Profile 8 with reencoded FEL ?

you can't ''properly'' re-encode and preserve FEL.

You could re-encode to mel with @quietvoid rpu extractor + x265.exe

Unless something changed, I believe DVDFAB strips away the EL in their DV MP4 conversion. You can verify this with mediainfo if you see only one video track that's labeled BL+RPU.

you can set it in dvdfap:

if you choose EL+RPU than you get it:

i just tested it with Saving Private Ryan, it has an FEL.

If I choose DV Single Layer for playback on my LG CX9 i get brightness pumping.
If I choose DV Dual Layer, the CX9 doesn´t play, but the LG UBK90 plays it correct.

I think all movies with empty EL (MEL) can be ripped in DV SL.

Ah that's interesting. I didn't know that dvdfab can now produce the same results as mp4muxer and that the ubk90 can actually play these dual track files. Wonder if it can do the same with TS files

[agneva]

Didn't try .TS yet, just m2ts.
Do you think ts could work with DV DL too?

Not sure if anyone's tested, but the x700 can. If the ubk90 can as well, then that potentially adds another device to the list that can play real FEL DV w/lossless audio.

[agneva]

Do you have a small test *.ts for me ? I would like to test it on UBK90.
edit: I tried myself a *.ts - its been played in HDR

[Manixx2020beyound]

thanks. so how do you convert the png file to SDR ? ffmpeg as well or madvr ? can you share your process ?

I use madVR because I consider it the best HDR to SDR tone mapping but it probably can be done with ffmpeg. I don't know how though.
So just open the png in MPC-BE/HC/madVR. it needs ''transfer=hdr'' in the filename.

The CX is rumored to have lost dual track mp4 support.

Can confirm that, no more Dual track/dual layer mp4 files with CX.

LG's dynamic tonemapping is garbage (at least on the C8).

Ouch, i thougth the lack of Dolby Vision support could be offset with Dynamic Tonemmaping and it seems its still garbage on CX according to HDTVTest:

I also have a TV
LG OLED55B6V.

For the movie The Lord of the Rings.
Which Dolby Vision profile is best suited for my TV? 5, 7, 8 or 8.1

Thanks in advance.

-Hello:

I have found this information:

Profile 5 single layer with exclusive support for Dolby Vision
Single layer 8.1 profile with HDR10 + Dolby Vision compatibility
Profile 8.2 single layer with SDR compatibility

From what i can read Profile 8.1 would be the best as it has HDR10 + Dolby Vision.

But I am a newbie at this.
If someone clears it up.

I would be very grateful, it is also of my interest since I have the same television.

B6 are (or were if firmaware did not change that ) play Dual track/dual layer DV MP4 files, so he betters keeps just using the Dolby muxer tool, profile 7, and get a Dual track/dual layer MP4 DV file.

''transfer=hdr'' is only to tell madVR: hey this file is in PQ.
it has nothing to do with ffmpeg.

is this parameter for ffmpeg or madvr ?

[RESET_9999]

I just answered that one post above.. that parameter is only for madVR...

if you want SDR screenshots, no need of FFmpeg. just tone map your HDR video straight in madvr.

[Manixx2020beyound]

This is an interesting read
According to this article dv-rgb8 is the old dv & LLDV is now mandatory on all doblyvision regular dv is not required
LLDV has it own profile as well.

yeah, your post was a bit unclear, but this one cleared it up. Thanks.

I gotta dig into madvr, still no idea how to display an image with it...
