I'm still learning, but I thought I read you can convert FEL to MEL without any visual loss of quality? (ie. no TV panels can display 12-bit FEL anyways?)
No, convert FEL to MEL will cause visible quality lose in FEL capable device.
See https://www.avsforum.com/threads/dune-p ... t-60582530
MEL image is 10-bit 4:2:0 subsampling, while FEL is 12-bit 4:2:2, I think.
Real 10-bit RGB or 4:4:4 panel can use dithering algorithm to imitate 12-bit color, so there will be a visible quality lose.

If I don’t care about FEL, the would the Zidoo be a better choice than the x800m2? (you can convert FEL to MEL anyways, right?)
I think most DV compatible TV support MEL mp4 through their internal player.
If you really don't care about FEL, Apple TV or any iOS device is capable of MEL playback.
See around viewtopic.php?p=123899#p123899
I personally use iPad to watch MEL, since its portable and I can watch it on bed. (Yes Im very lazy)

Some people here would disaprove this, but by now, iOS devices can play MEL (iPad pro 12.9 1600-nit) and dolby atmos 7.1 audio (eac3 through AirPods pro spatio audio). See https://developer.dolby.com/platforms/a ... e-support/. If you are as lazy as I am and don't want to spend extra money, this should meet your expectation. But still I would recommend proper FEL capable device and physical 7.1.4 sound system for the most prime watching experience.

Sorry to jump in like this.

I am very very new here and I just started using the tools generously provided by RESET_9999. I just wanted to know what is the workflow I should use to convert a MKV, dual layer P7 with TrueHD 7.1 audio, to something that can run natively of my LG C1 (or through Plex to my LG C1), with both Dolby Vision and Atmos. An example would be spider-man NWH.

To my understanding, I need to convert the P7 to a P5 or P8, and convert the TrueHD audio to something like EAC3. I am simply unsure how to get there using the Dovi_tools RESET_9999 put together.

Also, I see these terms fairly often, but I have no clue what ST-DL and DT-DL mean.

Thank you!!

Thanks again so much for the help.

Any advice regarding the Oppo 203 clone (M2910) instead of the X800M2?

They are command line tools.
See recommendation CX or newer at https://docs.google.com/spreadsheets/d/ ... jymVo/edit
I think almost no tv’s internal player is capable of DV MKV playback.
Do the P7->P8.1 conversion with any tool you like.
I wouldn't recommend converting trueHD, use the ac3 core in the file instead, it’s converted by the filmmaker and keeps director’s intention.

ST-DL refers to single track dual layer FEL file and DT-DL to dual track dual layer FEL.
Dolby Vision is very complicated, you may want to read more post to learn more of this.

first, edit the bat file with notepad and set tsmuxer.popup=YES and mkvtoolnix.popup=NO
then: 1 - 7 - 2 - 2

I've never used the Oppo clone so I will let others comment.

The nice thing about the X800M2 is that in a pinch you can always throw the disc in and play if you needed to. Say you just received a movie and wanted to watch before ripping.

Maybe update the Playback-Devices list?
It's been confirmed Apple TV and iOS devices can play BL+RPU with some conversion.
Or not, if that is considered conflicting to Dolby standards and rules

Apple TV can only play Dolby Vision P5 properly.

Infuse used to trigger Dolby Vision on TVs for some other profiles but it was only ever using the HDR10 base layer. They fixed it awhile back to stop triggering Dolby Vision on the display for those profiles.

If there is new information please link the source.

One little question guys. I have a movie in FULLUHD with dolby vision that comes on 2 discs, and I want to create a single disc with a profile 8, how is this usually done, I create two profiles 8 with the Dovi_Scripts tool as if they were different movies and then join them, or one and then I create profile 8?
I have previously joined movies that came in 2 discs with HDR, and I also do my profiles 8 with the Dovi_Scripts tool, but until now I had not come across this case of joining a movie from 2 discs to 1 with dolby vision.
Thank you very much and greetings

yes, I think you can use tsmuxer or mkvtoolnix to join the two parts together

I'm wondering, using Sony A80J Internal Player ( via USB ) does not play mp4 profile 8 DV files converted by ffmpeg to mp4 ( it includes DV metadata ) though player says "File can't be opened"
Are you sure ffmpeg can configure the DV box correctly?
Im using ffmpeg 4.4, it seems it ignores DV when generating mp4.
Maybe try mp4muxer for proper DV mp4 generation?
Most TV internal player don't support DV in MKV.
Yes, upon checking mediainfo it shows Dolby Vision metadata but the file fails to play, same happened on a Hisense U7G so looks like ffmpeg breaks video with DV. TSMuxer with ts worked perfectly.
