Japan’s national broadcast corporation NHK has developed a large CMOS 8K sensor for Super Hi Vision. At 21.5mm x 12.1mm it is the size of Super 35mm when cropped to 16:9, and does 120fps at a resolution of 7680 x 4320.

A rumour surfaced today (which was given the 2nd highest rating of plausibility by Sony Alpha Rumors) that Sony have a new NEX video product to come before NAB. Sony have confirmed they are strengthening the NEX range more than intended this year on the back of very strong sales. So as well as new lenses on the roadmap will we see a new video camera?

Consumer 4K is on the way, it is now as inevitable as the first 1080p stickers were on your TVs and cameras of 5 years ago. In an interview with DPReview, Nikon’s Tetsuya Yamamoto says that the Nikon J1’s (Aptina produced) sensor is already capable of a 4K horizontal resolution in video mode (although he doesn’t reveal the vertical resolution which I suspect would be lower than 2K).
Canon are developing their own RAW codec for 2K and 4K video. In a patent filed in July 2010 and published yesterday, Canon describe a codec which stores raw sensor data from a 12bit high resolution RGB sensor with Bayer colour filter array.
Don’t forget to download the original videos and view full screen The G1X is the first of Canon’s large sensor cameras to use their long awaited DIGIC 5 image processor. 3 years in the making, it largely determines how the sensor is downscaled to 1080p. It also determines resolution, bitrate, encoding and how much aliasing and moire is produced in the downscaling / pixel binning process. DIGIC 5 is built…
The Alexa Studio only shoots 2K and HD but apparently the consumer world has decided it is rubbish and we should all rush out and buy 4K cameras and displays. Hence the semi-pro JVC HMQ10 which goes on sale in March is the first 4K camera to break under the $5K mark or ÂŁ4K. I’ve been keeping an eye on what JVC are doing with their quick Falconbird processor lately…
