True. He records the same repeatable event (firing a laser) one pixel at a time. Due to the 1 pixel resolution of each event, he's able to record at insanely high FPS, and through recording that event for each pixel in an HD format, he splices together all the data into a single video.
It's not technically a single video of a single event, but it's still really cool.

no, it's recording a 4k picture which is 8,294,400 pixels per frame and removing each 1 pixel frame that he cares about, then mashing it back together again, to produce the 2 billion frames per second. He's not recording at 2 billion fps, he's taking image and mashing it together to make supposedly 2 billion fps. there aren't have enough hard drives on the planet to make a 2 billion fps video that long.
The video is only as many frames as necessary for light to go like ..30 meters. So, no its not that much data. I think you're mistaken about how he does this. He's not capturing in HD. He records only 1 pixel per laser shot. He then does this thousands of times scanning the whole frame to produce a 2D video.
Edit: In fact. You must not have watched the video, because he explains this in detail. Thats one of the awesome things about this guy, he doesn't gloss over the technical stuff.
You didn't even watch the video. He is sampling a PMT at 2 ghz. There are no CCDs or traditional cameras involved. He made a scientific instrument in the manner a the true scientist before 1900.

You should watch the video. The guy explains exactly how he records and makes the video, along with all the equipment he made and uses, and how it works.
I explained exactly how he did it in my previous comment. What you explained was incorrect. But yes, it's not technically a single 2 billion fps video.
It's not technically a single video of a single event, but it's still really cool.
