All this talk of 4K, high frame rate, 3D, and ever more precision and information in video signals is a good thing, right? Well, yes, but at some point, an engineering solution has to be designed to let it happen, and there’s reason to believe we might be getting a bit ahead of ourselves

 

NHK’s Super Hi-Vision 8K camera prototypes need an armload of SDI cables to deal with the torrent of data produced by such a high-resolution device, and until recently, 4K was just as difficult. Postprocessing and storing camera data at beyond-2K resolutions can still make for cumbersome workflows. At NAB, Blackmagic released a whole load of 4K-capable gear using the new 6-gigabit SDI standard that had, at the time, not quite been finalised. And finally, right at the end of its press conference, Sony announced its new 4K TVs. Early-adopter prices are no surprise at this point, but they’re still quite a lot cheaper than most of the 4K displays – such as Astro Design’s DM-3410 series – that have existed to date.”
