I can't get hard technical details on this but I suspect it relies pulsed laser technology to create pictures as if they were taken with a trillion fps camera. By strobing a time ramped laser over several seconds (minutes, hours?), accumulating images, and then running them at a tv frame rate could create the appearance. The world press is agog but offers no substantive information.

The fundamental problem with ultra high frame rates is collecting enough photons. People forget that the frame rate is also the shutter speed! The amount of light that one would have to pour onto a subject to permit a shutter speed as short as a trillionth of a second is enormous. So enormous in fact that any material substance would be instantly incinerated. My experience with ultra high frame rates is limited to very bright self luminous phenomema such as electric arcs and explosions.
