NHK 8K Super Hi-Vision camera captures native 120Hz footage, we go eyes-on at IBC (video)
We've seen plenty of 4K cameras, and we've even heard a whisper or two about 8K, but the quality of a viewing experience isn't tied only to resolution -- frame rate also comes into play, especially with fast-moving subjects. NHK's prototype Super Hi-Vision camera doubles the capture rate from the standard 60Hz to a much speedier 120Hz, yielding sharper motion. While the difference isn't noticeable with static or slow-moving scenes, it certainly comes into play when filming rapid-motion sporting events or panning the camera. The Japan Broadcasting Corporation's latest model was on hand at IBC in Amsterdam, and the advantages of a 120Hz cam were immediately crystal clear. Filming a rotating image that paired ordinary objects and cityscapes with letters and numbers, you could see the difference instantly, with the 120Hz image on the right side yielding far shaper details, while the left side was often a blurry mess. There's no software smoothing on hand here -- because the higher frequency comes directly from the source, it appears perfectly natural, and much more pleasant. We captured a video demonstrating the expo floor rig, but because our camera doesn't sport the same spec, you won't notice a difference in the hands-on clip after the break. You can see the difference in our stills gallery below, however, and you can take us on our word -- the improvement is quite dramatic.%Gallery-164700%
NHK develops ultra high-def camcorder with single 33 megapixel sensor (video)
As still cameras go, a 33MP sensor is rather insignificant, considering you may already be walking around with 200 megapixels on your shoulder. When it comes to camcorders, however, this is the real deal, especially when each and every one of those 33 million pixels is captured by a single, ultra high-def sensor. NHK's research arm, which developed the cam, unveiled it at the company's technology open house in Tokyo. This seems like the perfect imaging device to show off Sharp's 33MP Super Hi-Vision TV, but that display must have been on duty at another booth. Also, the Sigma DSLR lens was focused on a still life, without any mention of frame rate, so we're a bit skeptical as to whether this thing is fully functional at this point. Either way, it's still just a prototype, so you won't be shooting your home videos in quasi-IMAX resolution just yet. In the mean time, jump past the break for that motionless video demo.
