It’s been a while since we’ve covered the fps4000 camera mainly due to development time taking longer than initially estimated. However, Graham Rowan the engineer behind the camera has now posted the first 4k 480fps footage shot in RAW on the fps4000 camera which uses a sophisticated memory arrangement on the onboard super-fast flash RAM to be able to record lengths of time unimaginable before on slow motion cameras at high resolution.
This camera is a very different kind of technology from regular high-speed cameras that record to volatile DRAM. The fps series records to flash chips that are soldered to the mainboard and allow a variety of frames rates and resolutions depending on the sensor used but all is saved on the flash memory as a non-volatile stream of data. Modern SSD chips are so good at re-allocating reading and writing bits that the life of the components is now measured in decades of regular use instead of a few years. The fps4000 is using this technology fully to enable memory bandwidth magnitudes greater at a significantly reduced cost.
