We're presently working on a demo of an 80 camera digital system which streams uncompressed high definition images (1600 x 1200) direct to disk. In this system each camera is out of sync with its neighbor by exactly 1/80th of the frame rate (so each frame-cycle is divided evenly amongst the 80 cameras). The result will be a constant circular virtual camera move which does a complete 360 approximately every three seconds (80 frames) at an effective frame rate of up to 1200 frames per second.
The maximum frame rate that we can currently achieve in sequential mode (without interpolation) is 24,500 fps. (This frame rate is achieved by switching from camera-to-camera and is not achieved in each individual camera.)
