This is basically a whole bunch of photos of the same thing done over and over and then each frame is stitched together computationally to give the appearance of a single video at a trillion frames per second. It makes me wonder how much time it actually takes to get a single video.

The presenter didn't say how many times it took to get enough datapoints to computationally establish each frame for the video, but keep in mind the laser that is turning on and off is doing so in a picosecond (I think?) so conceivably after a second, you could have up to 10^12 (1 trillion) individual "shots".

Yeah, but I was mostly wondering about how long it takes for the computer to decipher, sort and compile all of the appropriate shots. If it's a few seconds then that's pretty cool, but if it's like a week, then bleh.
