Dolby Vision support .ts/.mkv files

Do these steps and as I just found out thanks to James pointing this out it’s almost certainly NOT the case.
It’s simply triggering Dolby Vision UI when it plays media back. Even SD will trigger DV with those settings.
It seems that Plex is just fooling us. That said it does still look pretty nice.
Even if only for eliminating the dazzling white forced subtitles on HDR10, I would still be happy to see it as an option in Infuse.

With regard to subtitles, you might give the ‘light gray’ color option a try.

This can be adjusted in the Subtitles section of the Playback Menu (swipe down while a video is playing).

Hi! I believe my question is relevant to this post, if not please correct me. I am trying to play an mkv file with DV although I am getting only the HDR mark on my LG B7. There is a post saying “It is DV but since its the new single layer version mkv it only plays on Nvidia Shields & Plex. On everything else it will say HDR10 instead of DV.”

Since I am not using neither a Shield (ATV 4K here) nor Plex (playing my files directly from my PC via a NFS server) is there a way to see the file in DV? Thanks!

Can you post up the specs?

It sounds like it may be a single-layer with fallback.

You’d like the MediaInfo details? Or something more? MediaInfo states the file as HDR10 whereas it is stated in the filename that the file is a DV one.

MediaInfo should be enough.

Also make sure you have the latest version of mediainfo. They added support for DV in mkvs not too long ago

Can you select the 3rd tab, and copy/paste the specs?

This appears to be profile 7, which is similar to the examples from earlier in this thread.

This type of DV is not supported on the Apple TV, and these will play in HDR10.

Ah ic… OK then thanks for clarifying, hoping for future support then!

Hello,

Isn’t AppleTV able to play Profile 8 too, as someone said in another thread ? Or maybe it’s different with .TS files ?
For example would the aTV be able to play this rlz WITH DoVI ?

The Lord of the Rings - The Two Towers (2002) Extended (2160p UHD BluRay x265 DV HDR DDP 7 1 English - Weasley HONE)
Video Format    : HEVC / Main 10@L5.1@Main               
HDR Format      : Dolby Vision / MEL / Profile 8.1 / BL+EL+RPU / SMPTE ST 2086 / HDR10 compatible
This is an x265-encoded Dolby Vision Profile 8.1 MEL as a Cropped MKV release with complete HDR10 fallback and a single merged video stream created with MakeMKV

Sorry if I’m a bit off topic.
I’m loving my AppleTV4k and we’re full Apple ecosystem at home. But I’d like to know if I need to invest in a ShieldPro to get DoVi on my LGCX.
Each time I’m about to download a video (and often it’s a huge file of course), I wonder if it will play the DoVi. And the nfo is not of much help, most of the time, because of this complicated story of Profiles layers.
It’d be nice if someone could sum up the situation regarding the profiles, the containers (mp4, mkv), and the TS files.

Thank you

AppleTV website says profile 5 only. Others have said profile 8 is used for videos recorded with the iPhone 12. Not sure if profile 8.1 is over and above that.

As for Dolby vision support for infuse I always go by the rule “if it came from a bluray it probably won’t work. If it came from a streaming service it probably will”.

Although unrelated to the topic, there is a way to “process” to single layer DV. Here’s a link to a single layer DV dvhe.05.06 in mp4 container that plays in InfusePro->ATV4K (without audio bcoz of this )

I processed that file from my UHD DV rip using tools and methods well documented in makemkv forum. (can’t post link in case cross forum posting is disallowed)

InfusePro detects correctly as DV and ATV as well my LG OLED65E7. LG picture mode setting defaults to DV. Quality compared with other DV P5 may be open to interpretation …

Hello!!! Finally, mkv can be played with Dolby Vision on our Apple TV! And for now, it is only possible through Plex.

Infuse is based on the Plex system, so I think we are very close to being able to see mkv on Infuse with Dolby Vision !!

Hopefully they will soon release the new Apple TV and we can play lossless audio, Atmos and DTS-HD, but in the meantime it would be amazing to play our double layer Dolby Vision movies on Infuse!

Infuse can play certain DV video also. It was recently added but there is a ton of hocus pocus going on with many players. Apple holds the key and it’s not easy to deal with their framework.

I think you’ll find some info in the below post that may show that what you’re seeing is not really DV.

Hello!! The new Dolby Vision files in mkv are not single layer, it is double layer, since what they have achieved is to put the two video files necessary to reproduce Dolby Vision in the same mkv file, so it is an improvement that Infuse has not yet implemented and Plex has.

No, it really can’t.
Look at the posts between me and James in December when I also made false assumptions.

Do This.

  1. Set Apple TV to Dolby Vision output
  2. Disable Match Dynamic Range (you can keep match frame rate enabled)

Then playback and file that isn’t even HDR and watch it trigger Dolby Vision.
Plex is simply triggering Dolby Vision mode on the ATV 4K when detecting Dolby Vision in the file. It’s a hack and nothing more.
The exact same steps can be used to make DV icon trigger on playback start in Infuse, again even for non-HDR.

Spot on. The only way a person will be able to play back the file is to go through the long conversion process of turning the dual layer into single layer. These files include the dynamic HDR metadata but any of the extra metadata that is sometimes included with Dolby vision (higher bit depth etc) is discarded.

What a lot of people don’t realize is I order for plex to properly do this the plex server would need to do this conversion on the fly and then send out as a new stream to the client.
