.MKV conversion leave Dolby vision and ATMOS intact ,please

[ian curtis]

I have an MKV file with Dolby Vision and ATMOS 7.1

My TV does not support MKV, so i need to convert it to something that my TV does support IE .MP4/HEVC or whatever you advise is best

I need to leave all the Dolby Vision and ATMOS intact

i tried many things since last night that claimed to work. They do not

Is there a dummy step-by-step guide for melon heads like myself on how to do this

i was hoping for a GUI 1 stop solution for melon heads, but that likely won't be the case

TIA mates

You could try https://www.videohelp.com/software/MkvToMp4 but I'm not sure if it leaves DV intact

It does look like a one-app/stop solution. Is that correct?

My head hurts trying to suss 2 or more programs,and one program loads another,etc

It all goes over my head(I wish,and maybe there is) there was a pictorial guide of how tp perform this momentous task

There are many ways to keep DV and ATMOS intact,i get tone of advice on what programs to use,but sussing them all out is way over my head

If the pic guide was done well for melon heads,i could follow it

But for now i am in dark

I hope this is the ticket,as i need to keep DV and atmos intact

My guess is it wont,cuz my life is not that easy lol

I have no idea if it will work with your files, but AVIDemux has a copy copy>MP4 function.

Just open your file with it, then for both Video and Audio Output, leave both as "Copy"

For Output format, from the droplist choose "MP4 Muxer" and then save your file.

You never know...

Alternatively, you could attach one of your files here (max 500mb) and we can play with it to come up with a solution.

PS: I feel ProWo lurking...

Thank you

is "ffmpeg" now a stand alone?

I will try

[Ennio]

I don't know if ffmpeg handles Dolby Vision mkv to mp4 correctly. In case your mkv contains DoVi with two layers, there's two options to create a mp4: so-called "dualtrack duallayer" or "singletrack duallayer". Where I can imagine a TV being picky, should two-layer DoVi be supported in the first place.
Another thing to consider is what type of Atmos there is in your mkv. It comes with lossless TrueHD or lossy EAC3 (often named with JOC). I wonder if the TrueHD type is supported in mp4 and if your TV can handle it.
Btw you can use clever FFmpeg-GUI as a frontend to ffmpeg.

I have no idea what a "front end" so something else is

Is there a step by step pictorial of all this?

[Ennio]

A frontend means a graphical interface. In this case to ffmpeg.exe which on itself works with command lines. I don't know if there is a step-by-step tutorial to DoVi mkv with Atmos to mp4.

But in short:
Download clever FFmpeg-GUI and ffmpeg. Run the "clever FFmpeg GUI.exe". A graphical interface will show and will ask you to point to the bin folder where you have ffmpeg.exe. It then will ask you to choose an output folder.

After this you can "Select Source". Then click on "Main". Click on "Multiplex". At "Container" choose mp4. Click on "Multiplex".

There will be when ProWo arrives. They are the author of Clever FFMPEG GUI.

As Ennio said, start the app and follow the instructions.

btw
You can remux your mkv to mp4 with clever FFmpeg-GUI. All streams are copied as they are.
But I've no idea if the mp4 container can handle Dolby Vision and ATMOS 7.1.
So the best way is to try it.

But I've no idea if the mp4 container can handle Dolby Vision and ATMOS 7.1.

Since Dolby itself did provide links to mp4 files with Dolby Vision and Dolby Atmos streams in an mp4 container, see: https://developer.dolby.com/tools-media/sample-media/video-streams/dolby-vision-streams/
I think it is fair to assume it is possible with mp4.
(afaik both mp4box and ffmpeg should be able to mux those files)

Thx Selur for the info.

It is indeed common practice to mux Dolby Vision in mp4. About Atmos I'm still not sure if TrueHD Atmos can be muxed in mp4 nowadays. I know EAC3 JOC can.

But as for DoVi, last time I remuxed a P7 mkv to mp4 with clever FFMpeg, the singletrack-duallayer hevc-stream was copied to mp4. Which is valid of course, but it may be possible that if P7 is supported by OP's TV, it's only for dualtrack duallayer. Which would not surprise me because it's a similar way to how it's constructed in m2ts on a DoVi bluray.

I always interleave/de-interleave BL and EL with quietvoids's dovitool before processing further, but I don't know whether (Clever-)FFMpeg can also create these intermediates during a remux process.

If your tv can't handle mkv format i doubt it will support dv and atmos.

I have the LG G3

It certainly does support that

What i am on about is "Via a USB"

[johns0]

I would have to say that lg is a brand i would never buy,not making mkv as a not recognized video is weird since i have played mkv on lots of tvs in the last 10 years

[usually_quiet]

I downloaded a Zip archive containing the online manual for the LG G3. Link to download archive - https://gscs-b2c.lge.com/downloadFile?fileId=T5lQdqdfBmDD01KG6IDhnQ

The manual seems to have been written to apply to more than one LG TV but according to the Supported Video File Formats section (pages 146 to 148 of the English language version of the manual), playback of MKV files with HEVC video is supported. The manual mentions Dolby Vision support for media files, in a general way on page 146. It is apparently supported if the TV itself supports Dolby Vision. The manual doesn't provide any specific details regarding support for Dolby Atmos in media files. It discusses what the technology does and how to access it, but does not mention compatibility with specific types of container files or video codecs.
