I'll partially copy two interesting comments from that thread:

> [A video with] 60 frames per second only allowed to identify the speaker and the number of people in the room.

> The demo in the video is based on a high-speed (1000+fps) recording by a special camera, not on 'normal' video.

The first set of demos in the video, anyway. At the end they show the results of a special technique that uses 60fps video.

A standard mobile phone today can do 240fps. We're only a few years away from 1000+ for in everyday devices.

Really? Isn't speed limited by the amount of light that can be received in a small lens like on a phone?

>Isn't speed limited by the amount of light that can be received in a small lens like on a phone?

It's also limited by sensor noise and efficiency.

Presumably, we'll push all three of these limits over the next few years.

The trick is to add the signal of many pixels together, forming a larger effective sample. The output video is very low-resolution and has a low dynamic range after noise removal, but can get hundreds of FPS in decent lighting.
