- gus_massa 12y agoI'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.
- Gracana 12y agoThe first set of demos in the video, anyway. At the end they show the results of a special technique that uses 60fps video.
- GuiA 12y agoA standard mobile phone today can do 240fps. We're only a few years away from 1000+ for in everyday devices.
- Potando 12y agoReally? Isn't speed limited by the amount of light that can be received in a small lens like on a phone?
- wyager 12y ago>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.
- sp332 12y agoThe 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.
