Just for clarification, it was the 'equivalent' of a trillion fps, i.e. lots of regular high speed videos composited with very accurate timing. IIRC he said they'd need > 500 laser pulses per video but they actually used millions.
It was very cool though watching things like subsurface scattering in fruit leaving glows after the light pulse had left the object. There's something very strange about watching light 'ripple' around a scene and there being a lag/delay between a pulse travelling by and moments later it's glow reaching the objects around it.

(The videos at the conference were much better than that but can't find a link).
