Don’t hold your breath for 5K video from a Nikon DSLR as 12 bit 1664 x 1100 resolution is what is provided right now. But the live-view stream is 4992 x 3280 pixels and it should be available to be captured. Even if live-view is captured, it would likely be at a lower frame rate than 24fps.
When the Magic Lantern team first started capturing live-view on Canon cameras they were not sure what they could do with it but they quickly made it into very useable frame rates. So it will be interesting to see how this development goes.
You can view the thread about this raw video hack on the Nikon Hackers forum and below is a raw frame example of what they have done so far.
Microsoft’s PlayReady 3.0 DRM, which is set to be released with Windows 10, is raising some red flags about restrictive and invasive digital rights management.
It seems like the impetus is to provide “secure” 4K streaming and increase the market for 4K streaming services on computers running Windows.
The biggest concern is that users will be compelled to use this technology if they want to stream in 4K. This has not been confirmed yet.
If a movie is playing in a movie theater right now, and you would like to have access to it on your Windows PC, they might make it available on some Windows PCs that have the higher bar for content protection [PlayReady 3.0 DRM]. — Nishanth Lingamneni (Microsoft)
Resource Online has an article titled Why Canon Needs to Rethink Their Ridiculous Pricing on the C300 Mark II where they compare the Canon C300 Mark II against the Blackmagic Ursa, Sony FS7, and the Red Scarlet. An interesting read and comparison of these more costly video cameras.
See Nvidia’s webpage on the Shield for more information, but some of the interesting claims are that it’s components are twice as powerful as the Xbox 360, and that it can stream 4K video. The Shield runs off a Tegra X1 processor, has 3GB of memory and has a 256-core Nvidia Maxell GPU.
The OneRiver Media Blog has posted a thoughtful article about the Blackmagic Ursa Mini titled Insight Into The Blackmagic URSA MINI.
This is the most poignant discussion on the subject we have seen so far and it does a good job covering the value of this camera and whom it might make sense for.
Although it may appear that Blackmagic may have built the URSA Mini as a direct competitor to the Sony FS7 (a camera which I really like), this is actually not the case. In truth, Blackmagic had an obvious “hole” in their camera product lineup with regards to size, ergonomics, and features, and the URSA Mini was their answer to that missing product void, whether it’s a close competitor to the FS7 or not. In reality, the Sony FS7 and the URSA Mini are somewhat different types of tools.
Eh Daily has an article titled What is HDR and Why is it Important in 4K TVs?.
This article provides an important overview of why one should be considering the dynamic range of TV and not only its resolution.
All other things being equal, we would rather have a 1080P TV with a high dynamic range than a 4K TV with a mediocre dynamic range. However, there is no reason why we can’t have both 4K and HDR other than the currently prohibitive pricing.
