Are There Any Dolby Atmos True HD 7.1.4 Movies

[Richx200]

I've been looking around and haven't been able to find any movies in Dolby Atmos True HD 7.1.4, so I can check my ceiling speakers. The best I've been able to find is Atmos True HD 5.1
Are there any available?

I've been looking around and haven't been able to find any movies in Dolby Atmos True HD 7.1.4, so I can check my ceiling speakers. The best I've been able to find is Atmos True HD 5.1
Are there any available?

As it happens I have the Dune 2 4k UHD Blu-Ray on the table infront of me. (Not watched it yet). I had a look at the tiny writing of the specifications and it says:

2160p Ultra High Definition 16x9 2.4:1

Dolby Atmos TrueHD: English

Dolby Digital: Canadian French 5.1, Latin Spanish 5.1, English 5.1, Audio Description Service

The Dolby Atmos TrueHD part should mean that it will play in 7.1.4 (if you have an Atmos capable receiver and the necessary speakers). I think they omit the speaker configuration as Atmos can use a variety of different ones.

Could you perhaps be reading 5.1 in relation to the Dolby Digital content?

AFAIK, there are no Dolby True HD tracks encoded in fixed 7.1.4 audio channels.

Instead, Dolby Atmos encodes channel-less object-based audio and it's the job of your Atmos decoder to render that into distinct audio channels, from basic 2.1 all the way up to 11.1.8

To test 7.1.4 functionality, you can download a variety of Atmos encoded showcase clips from here: https://www.demolandia.net/cinema/dolby-demo-trailers-hd/page-9.html

Or directly from Dolby: https://www.dolby.com/ja/about/support/guide/downloadable-dolby-atmos-trailers/

I did check out the demos and everything sounds good but, these are Dolby demos finely tuned to sound good. I haven't heard any Blu-ray or streaming that sounds as good as the demos. @-Matt- his insert of the Blu-ray label shows 5.1 if all Atmos is 7.1 or better why the 5,1?

Atmos itself is channel-less and can be rendered as anything between 2.1 and 11.1.8 channels.

The "5.1" in Matt's screenshot refers to the compressed Dolby Digital tracks that are included alongside the Atmos track.

So this, movie's audio would be Atmos 5.1 ?

This movie's audio would be anything from Atmos 2.1 to Atmos 11.1.8, depending on the capabilities of your Atmos renderer and playback system.

5.1 is the maximum that you can get if you have no Atmos-compatible hardware.

Isn't some channels baked? For like music and speech?

To date, the only height-channel audio I've noticed in Atmos soundtracks (Amazon TV / Apple TV+ / 4K UHD disks) is a faint bit of ambient sound. But while I haven't been wowed by the height channels per se, the typical Atmos mix does seem more seamless, and less like multiple mono channels.

You're right, I should've been more precise.

Atmos is based on a few traditional channel-based channels with numerous object-based channels on top.

Dolby then provide logic to up/downmix that into a variety of playback formats.

At the extreme end, JBL's "Boombox 3 WiFi" has two coax drivers and one woofer, yet supports Atmos playback:
