This suggests that the video accompanying that quote shows 300k fps footage, but that can't be right.
If you film at 300k fps and play back at a (generous) 60 fps, that is a slow-down factor of 5000. The footage of the tennis racket and the bursting balloon is slowed down, but not 5000x. Perhaps 50x, perhaps even 500x (doubtful) but definitely not 5000x.
Say the pool jump or the racket swing each takes only 0.1s real time. At 5000x that would mean 500s, or about 8 minutes. Clearly, the slow footage isn't _that_ slow.
This being said, the Nvidia results do look very impressive, I'm not trying to take away from that.
- slivym 8y agoThe tennis racket jello shot is 2500 FPS and then played at 30 FPS and interpolated to 120 FPS. The 300k number is just pure screw up in the article. The actual paper states it is 300k frames total generated not frames per second.
