4K video has just begin to become a standard for the future. They are testing 8K displays and cameras in Japan. John Fingas:
TV broadcasters are still wrapping their heads around 8K, but that isn’t stopping NHK from pushing the technology forward. The Japanese industry giant is coming to the annual NAB trade show with a slew of 8K inventions, headlined by a high-speed camera.
240 frames per second at 8K. Fret not. New iPhones already shoot 4K video and 4K HDR video TVs are nearing the $500 mark. The future is coming.
