Chronos 1.4 is the brainchild of engineer David Kronstein, who first demonstrated the camera’s hardware and recording capabilities with a production-level prototype under his YouTube handle ‘tesla500.’ The camera can record 1,057 fps at 1280 x 1024, and up to 21,650 fps at lower resolutions.The math pencils out as follows:
When viewed at the standard video frame rate of 30 frames per second (fps), 21,650 frames would take about 722 seconds, or 12 minutes to watch.
The iPhone can natively capture 240 fps, which slows 1 second of action into (240/30) 8 seconds of viewing.
DPReview has an article on the Chronos 1.4, and there's a demo video as well.
Chronos High Speed Sneak Peek
UPDATE: Watching the sneak peek makes me think the native playback rate on this camera's files is 60 fps, in which case 1 second of action will blow by in a mere 6 minutes at the highest frame rate.
UPDATE 11/25/16: The Kickstarter campaign goal was achieved in five hours.
