NHK 8K Super HiVision camera captures native 120Hz footage, we go eyeson 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.

NVIDIA GeForce GTX 670 review round-up: ‘just get here if you can’

NVIDIA GeForce GTX 670 review round-up: 'just get here if you can'

While the world still waits for the GTX 680 to reach Newegg, NVIDIA has pushed ahead with the next card down in its stack: the $399 GTX 670. This more affordable option keeps most of the main Kepler credentials intact, but it necessarily makes a few compromises on the computational side, with fewer processing cores (1344 instead of 1536) and texture units (112 instead of 128) as well as slower base clock speed (915MHz instead of 1006MHz). Is that likely to be a problem? Judging from reviewers' responses published today, which cover cards from a range of vendors, probably not. In fact, as TechSpot puts it, "there's very little to critique," because the GTX 670 matches the performance of AMD's flagship Radeon HD 7970 at a much lower price. AnandTech's benchmarks put the reference board only ten percent (or a handful of fps) behind the GTX 680 in many recent games, leaving it "nipping at the 7970's heels," but it was still plenty powerful enough to play Arkham City or Battlefield 3 at 5760 x 1200 with high settings. PCPer's stats put the new card 15 to 20 percent behind the 680, but found good scaling in SLI mode. The Tech Report found the the GTX 670's cheap stock cooler let it down slightly, with a "friction-filled" idle noise well above the top-end Radeons and even above the dual-GPU GTX 690 -- but under load it conducted itself relatively well. We could go on, but ultimately if you're looking to buy this card then you'll want to do your own research at the links below, and then do a raindance.
