I think this might be a re-release with the Dolby Atmos remix (it's already available on Vudu)

In 2014 this did not have Atmos for sure

Warners announced a tie-up with Dolby to remaster their stuff in Dolby Vision a year ago so I'm not surprised that Atmos was part of the deal for those movies which didn't have Atmos already.

Sony announced their own tie-up with Dolby for HDR mastering in September 2015 and several Atmos-remixed 4K-remastered Blu-rays followed after that (in North America, anyways) though Sony are more reticent about adopting Dolby Vision as a HDR delivery system for their movies either theatrically or on 4K OTT/UHD Blu, although Pixels was indeed released in Dolby Cinema (Vision/Atmos)).

2012. Brave was the first.

IMDB is as reliable for Atmos as it is for 4K.
In other words, not really. But in this case I believe The Lego Movie was not released that way, at least not initially.

I find it unlikely and that these are cover mockups. DTS-MA on the BD, Atmos TrueHD 7.1 (with Dolby Digital 5.1 companion track) on the UHD.


Remember the convincing Atmos label on Warner's re-release of Interstellar? Turned out to be bunk.

Can one of you who has a grip on all of this (Penton-Man, Geoff D, Peter THX, etc....) comment once again on the benefits of using a 4K display with standard Blu-ray playback? I will be purchasing a Sony 65" XBR-65X930D later this year but I will be using a Sony Blu-ray player re-configured as region free. This is exciting stuff! I purchased a 60" E series Vizio two years ago and it was the nicest TV my family ever had. Within weeks of setting it up my wife started her final battle with cancer and was to sick to enjoy it with me. Now that it's just me and my daughter' I don't have that voice of reason to guide me anymore....(I swear it was like being married to Spock...lol). I think putting a good investment into PQ and letting things develop in the UHD player department is a reasonable approach.

Dolby site doesn't have Lego Movie on his list for 2014, so Imdb is correct.....

The original mix is the 5.1 DTS-HD MA and I think it's only right to have it ported on the UHD disc as this is the only way to preserve it....

UHD Blu-ray seems to work different when in comes to layers and bitrates. On Blu-ray the maximum bitrate is 48Mbit for audio/video no matter if it's a BD25 or a BD50.
On UHD Blu-ray the maximum bitrate depends on the disc type. BD100 supports higher bitrates than BD66.

So if you want to put a 20 minute short film on UHD Blu-ray in the highest quality possible you would have to use a BD100 even if the encoded movie is only 20GB in size.

Will UHD Blu-ray's have special features for movies ?

Well if that's true that makes absolutely no sense whatsoever

It's NOT true.

Both 66GB and 100GB discs support the exact same bitrates: up to 127.9 Mb/s for the High Transfer Rate (outer) zone of a disc and 109 Mb/s for the Low Transfer Rate (inner) zone. There is also a Default Transfer Rate of 109 Mb/s for those discs, with 81.7 Mb/s also listed in the July 2015 white paper. 50GB UHD discs will have 64 Mb/s for LTR and 81.7 Mb/s for DTR.

What exactly are the outer and inner zones?

As far as I can understand it, they quite literally relate to the radius of the disc's surface. Because proper 66/100GB discs have a greater data density than 50GB (33GB layer vs 25GB layer) they can spit out more data, [edit] naturally this means you need a faster speed to read the discs. 5000 rpm was decided upon for the higher transfer rates of UHD Blu.

However at the very inner portion of the disc (about 8%) the speed would exceed 5000 rpm when using the highest bitrate (think of how a runner in the inside lane is generally held to have an advantage) and could create more audible noise, so the bitrate of that 'LTR' zone is curtailed slightly to 'only' 109 Mb/s until the 'HTR' zone is able to take over. Make sense?

Yes that makes sense, I'd not considered that before.

Think CLV (Constant Linear Velocity).

With the LaserDisc format we had CLV and CAV (Constant Angular Velocity) disc types. CAV allowed for stills, slow-mo, reverse play, etc.

First, very sorry for your loss.


For your question, a good 4K display will wring every last ounce of picture out of your blu-rays. On your particular choice of display, black levels are outstanding. When I got my first HD display, I saw details in my DVDs (and flaws) I had never seen before. I got similar results when I got my UHD display (a Sony XBR-X900B). You may find yourself going through your BD collection to give your favorite movies another look.

So some of the film will have less bitrate? I hope they reserve the LTR part for extras then.

^ Wot he said.

Fritz, don't be put off by all the bullshit people spout about upscaling, it's *superb* on the Sony though @ 65" you might start noticing the seams a bit more (depends on your seating distance).

Remember, the bitrate is NOT constant, it's variable. Blu-ray goes up to 48 Mb/s (or about 54 Mb/s for actual user data rate) but it doesn't max it out for every second of every movie, that belies the whole point of the compression that they use! So just because the very first portion of a UHD layer is capped at 109 Mb/s (about 122 Mb/s) doesn't mean it will use every last bit of it anyway.

Thanks guys!
