Been doing a few DV vs HDR10+ comparisons with Back to the Future 3. Sources are the Shield/Plex (mkv from 1.15.4), Vero 4K+/Kodi on the 4.9 test kernel for HDR10+, and a Sony X700 (m2ts from full disc backup via USB). All sources routed through a Marantz AVR to a Panny HZ980 OLED (supports DV and HDR10+).

First step was to configure settings on the TV to give as close to like for like as possible for DV vs HDR10. I had noticed from my ATV that DV out of Disney+ did not look at all good in the TV’s “IQ mode”, but found one of the other DV picture modes could be customised to match my HDR10 profile on all user-selectable settings.

For DV I have been using LLDV. This might be an issue with the Panny, but for TV-led DV there is a strong tendency to overcook the lift in shadow detail for all DV sources. So eg the saloon bar scene early on looks almost floodlit, totally unnatural. LLDV looks much more “right”. Maybe a firmware update will fix this.

On to the comparisons. First of all, regardless of DV/HDR10, the Shield, for me, does not quite produce the detail levels I see from the ATV (Infuse Pro), X700 and the Vero.

HDR10+ from the Vero is very good, and the Vero has a rock-solid user experience as a media player. The X700 DV does add some additional richness/vibrancy, eg when Marty runs out from the saloon and is chased through the town, the sunshine has a touch more punch.

The Shield is like a slightly gaudy version of the X700. In overall tone it is closer to the X700 than the Vero, but I think it’s a touch too warm and there is a slight loss of detail (this is quite noticeable when comparing Spiderman Homecoming across sources).

So my conclusion is that HDR10+ from the Vero is not quite as good as DV on the X700, but I much prefer it to DV from the Shield. Given how flaky the X700 is as a media player, I think the ATV and the Vero will be my primary sources for now, and I’ll see how things progress with the Shield.
What are your findings on the AppleTV 4K with Infuse Pro? Are you getting DV at all with it? I have tried many of the options here in this thread and haven't been able to get DV with this, if it is even possible? I have done various combinations with DVDFab, MakeMKV and TSMuxeR.

Hi.

What app options are there for Dolby Vision playback via a Nvidia Shield TV Pro (2019) on a Panasonic GZ950 OLED? I’ve read some mention Plex beta app, is that currently the only option?

Thanks.

There is no real DV from Infuse Pro on the ATV from UHD-mkv's, but you can be tricked into thinking it works. Very occasionally, my ATV will re-set its DV enabled status and invite me to "try Dolby Vision". On enabling DV, you need to be careful that the system settings have "match range" enabled for dynamic range. Otherwise, you'll get the DV logo on your display when playing an mkv, and at first I thought that meant DV is working as I was playing a DV mkv, but then found out I also got the DV logo when playing an HDR10 title. The reason for this was that match dynamic range had accidentally got disabled. When match range is enabled in system settings, I always get HDR10.

Couple of issues to consider with the ATV: no passthrough of DTS-HD/Dolby TrueHD, but Infuse will output hi-res PCM as far as I can tell. I have surround channels but not overhead, so for me I am ok with Infuse but lack of hi-res passthrough could be a dealbreaker for some. Also, I noticed that ATV/Infuse seem to use weave deinterlace on everything. So native 50i material is unwatchable on the ATV, as it throws away the 50Hz motion. It's ok with TV drama that is progressive at source but authored in a 50i stream (lots of UK TV drama is like this), but just dreadful for genuinely native interlaced material (e.g. older studio TV material). This may be a general issue with the ATV, not just with Infuse. I looked briefly at Plex, but lip-sync on the ATV with Plex is such a joke the demo did not last long.

Yes that can be tricky so I always make sure I check the HDfury web GUI to see what is being sent. I’m the one who discovered the HDFury LLDV/Dolby Vision hack for HDR only displays/projectors and shared it with the world, so I know this well and check It often.

So the answer is, Infuse Pro only plays the HDR base layer of the DV rip so I’m only getting HDR10 and no DV, correct?

I do like the results of it with Dolby Vision forced on with Match Dynamic Range set to off. The AppleTV 4K does an exemplary job of mapping it to pseudo Dolby Vision but I’d love to feed it real DV if at all possible of course!

Say I use the x700 to play dolby vision m2ts file, but I want audio from my pc since I use headphone and virtual surround software instead of speakers. Is there a way to sync the video output from the x700 and the audio output from my pc instead of manually doing so which is a PITA each time?

Unfortunately like the previous poster said, you're never going to get real DV from UHD rips on an AppleTV. The main issue is that the hardware is only capable of profile 5 DV, which is single layer and in a different color space from the profile 7 found on UHD disks. So even if you have an MEL title that you can safely convert to single layer, you're still likely to have color accuracy issues to the lack of a color space conversion between the different profiles. With tsMuxer, you can alter the source code (there are also compiled versions floating around) so that instead of spitting out profile 8 for single layer files, it would produce profile 5 files. People have used this for their ATV, but like I said, there are likely to be color issues.

DV could be only supported for Streaming apps....
I really hope it supports dual-layer FEL + lossless audio with PLEX. If it does, I think I'm going to buy one.

early reports does seem promising

YES 👍 For uhd full menu ISO’s
New it.
That’s great!!
Hopefully Now new improvements on ripping method might have to change.

oh, that is nice..
now Manix please do a small capture to verify the colors.
please also try DV MKV playback

-Hi there:

Could you provide me with the links to the latest version of
-python
-mp4muxer
and the one that brings everything incorporated including FFmpeg (The version that a user made that brings everything together.)

Thank you very much.

-Greetings to Crodiales.

Thanks. So - Latest TSMuxer release (JustDan) is the perfect way to go creating DT DL P7.
Final question - your signature refers to a .TS file from DolbyLabs (I downloaded) and you refer to it "fixing" a DL problem on the x700? I'm confused based on what you say above...
yeah, the TS/M2TS files created by tsMuxer have a bug.
When you stop playback of a DT-DL TS file, the next file you play will have a green or purple tint on it. The x700 and the Oppo somehow get locked in that mode and only(besides rebooting) playing the TS demo file in my signature will unlock the player. I think playing back an original UHD-BD should unlock the player as well.
My PUS7304 (a TV with android) has the same problem when I play a FEL movie converted to mp4 with dvdfab, but If I play a MEL movie It fixes. If you use yusesope FEL to MEL tool that doesn't happen.

Hi,
Can you create a working DTDL ISO file for this guy?

I tried to do it with tsmuxer from the dtdl mp4 file, but it only plays in lite mode on Dune.
