The majority of 4K movies (75%) I tested have bitrates over 100 Mbps and many seconds where bitrates spiked over 100 Mbps. Some have 100s of seconds where bitrate spikes over 100 Mbps, and will most certainly cause problems if played with bandwidths less than 100 Mbps on devices that don't buffer well such as the LG TV or Roku TV .

Also for a 2160p60 10-bit 4:2:2 signal. This is a constant signal. It doesn’t matter if you’re only displaying a static UI, native 480p 720p, 1080p or 4K content. Even USB 2.0 is MORE than enough to stream 4K HDR remuxes. That’s because USB 2.0 has a theoretical 480 Mbps max speed while 4K Blu-rays won’t go over 90-100 Mbps.

The preliminary spec for 4K discs was revealed at CES 2015, after which the Blu-ray Disc Association made the Ultra HD Blu-ray spec official(along with the name and the logo). This format supports a resolution of 3840 x 2160, and while the specification is no guarantee that a film was actually shot and edited in 4K it does also offer additional tec...
The UHD Blu-ray specification also includes object-based immersive soundtracks such as Dolby Atmos and DTS:X. Some Blu-ray discs already support these formats, so it's not unique to UHD Blu-ray, but the next-gen audio soundtracks are more prevalent on Ultra HD Blu-ray discs. So far Dolby Atmos has been the prevalent format on 4K disc releases, but ...
4K discs also support an optional digital bridge feature, allowing you to copy Ultra HD Blu-ray content to an external hard disk drive and portable devices such as smartphones and tablets. The spec also mandates all Ultra HD Blu-ray players be able to play legacy Blu-ray discs. Sadly, 3D isn't featured in the Ultra HD Blu-ray spec – but with the ma...
Current UHD Blu-ray players can be sorted into two categories: the under-£400 (affordable) models and the £600-and-above (high-end) players. The Panasonic DP-UB9000 is the high-end Blu-ray player of choice these days (we're also big fans of the Pioneer UDP-LX500 and Oppo UDP-203, but both have now been discontinued), and it's a serious bit of kit t...
Ultra HD Blu-ray discs are now on sale worldwide, with major studios such as 20th Century Fox, Sony Pictures and Warner Bros all in on the action. Disney joined the ranks in 2017 with Guardians of the Galaxy Vol. 2 as its first 4K disc release (and still one of our most-used test discs) before following up with Thor: Ragnarokin 2018. The likes of A...
Yes, Ultra HD Blu-ray players are fully backwards-compatible with existing Blu-rays. Ultra HD Blu-ray discs won't play on old players, though, and you can't upgrade old decks, so you will need a 4K Blu-ray player in order to play 4K Blu-ray discs. When it comes to regional restrictions, the good news is 4K Blu-ray discs have just one region code: w...
An Ultra HD Blu-ray player will work with pretty much any TV, but unless it's a 4K Ultra HD TVyou won't see the disc's full-fat 4K resolution on screen. If your TV doesn't support it, the player will downscale the disc's content accordingly. Any 4K TV should deliver a 4K picture, but only TVs with more recent specs will be able to take full advanta...
Yes and no. If your system currently uses an AV receiver to do the HDMI switching, and carry audio/video over HDMI around your system, then this won't work with 4K Blu-ray unless your AV receiver is 4K-compatible. The good news is most, if not all home cinema amplifiers in the market now are 4K compatible, including the excellent Denon AVR-X2700H a...
We certainly think so. It may be an increasingly niche market but 4K Blu-ray continues to impress us with its incredibly detailed picture quality, and better hardware and advances in HDR technology have improved performance even further. Ron Martin, VP of Panasonic's Hollywood Lab and a crucial player in the development of Ultra HD Blu-ray, told Wh...
You shouldn't hold your breath for 8KBlu-ray players or 8K Blu-ray discs. While 4K Blu-ray has proven fairly popular and will likely stick around for a long time to come, it's still a drop in the ocean compared to the popularity of streaming and we can't see a future in which any company is prepared to invest the huge sums of money into a new physi...

Feb 25, 2016 · Allegiant was shot digitally on Arri Alexa XT and 65 cameras at a resolution of 3.4K and 6.5K and the filmmakers used a 4K digital intermediate, which means that the UHD Blu-ray will be able to take full advantage of the higher resolution of the format. In addition the transfer uses a wider colour gamut and HDR10; whilst the soundtrack is in Dolby Atmos, which the film was mixed in for its ...
