NAB2014-ARRI Developing a 6K 65mm Digital Cinema Camera?
ARRI Developing a 6K 65mm Digital Cinema Camera?While the 6K market may start to get crowded over the next few years, what’s so special about that resolution? As an acquisition format, 6K gives you all sorts of options for better-looking 4K with the ability to reframe and stabilize. That’s why it comes as no surprise that ARRI looks to be developing their own 6K camera, but instead of squeezing those pixels onto a Super 35mm sensor like the RED DRAGON or the new Kinefinity 6K cameras are, the company is letting them breathe on a gigantic 65mm sensor.While this has to be classified as a rumor, the sources confirming the existence of the camera are as legitimate as they come (and if they are just joking, some confirmation would be fantastic). It looks to be in testing right now on Tarzan, and another feature I can’t quite decipher (maybe you guys can help):

65mm sensor, 中片幅的攝影機了.
The data rates of an uncompressed RAW 6K camera would also be tremendous, coming in somewhere around 650MB per second at 24fps and 12-bit (multiple terabytes per hour).
一秒鐘650MB的資料量...真是可怕...
一般120底片實際寬度不過56mm，現有的數位機背大部份僅能達到645規格，還遠小於65mm。
另外錄影時650MB/S的資料量恐怕要用SSD RAID才能達到穩定的存取，但是容量又是另一個問題。
