The BBC has recently released an article titled V-Nova streaming tech produces 4K compression ‘worth watching’ that is an important development in the adoption of all things 4K. V-Nova is stating that they can stream 4K in 7-8Mbps as compared to the 12-16Mbps that Netflix presently uses for 4K. V-Nova also has some big names behind it like Intel and Sky which is a good sign for 4K.
Crutchfield has a useful article titled HDCP 2.2 copy protection and 4K Ultra HD TV: What you need to know if you’re buying a TV or home theater receiver that provides this salient warning:
With the popularity of 4K TVs, you’ll be seeing loads of new 4K source components in the next few years: 4K Blu-ray players and media players for sure, and eventually, 4K-capable satellite and cable TV receivers, too. Every one of those components will have HDCP 2.2 copy prevention. If you attempt to connect one of them to a 4K TV that doesn’t support HDCP 2.2, you won’t see a 4K picture. That’s the sad truth whether the content is streamed or downloaded from the web, or played from a disc.
Not much is known about this new, smaller 4K camera apart from the 1 inch CMOS Sensor and the 10 times optical zoom lens (24-240mm equivalent with an aperture of f2.8 to f5.6).
The other similar cameras on the market are the Sony FDR-AX100 and the Panasonic FZ 1000, both of which also have 1 inch sensor and shoot 4K video.
Nvidia’s new Titan X is a wonderfully powerful video card that is primarily marketed at gamers who want to be able to run games at 4K with a single video card.
Unfortunately H.265 video decoding is lacking (unlike in the Nvidia GTX 960) and we haven’t heard yet about HDCP 2.2 (Digital Rights Management encoding that will effect video playback) but it does not appear to be in this card.
There is an HDMI 2.0 port on this video card, thankfully. But until the H.265 and HDCP 2.2 are included we recommending holding off unless you can’t wait.
Visit ARRI’s website for more information, but the feature that we find highly relevant is the in-camera ProRes at 4K. This camera has the same sensor as previous ALEXAs but there are other significant changes around processing and color management.
