Graeme Taylor pointed his inexpensive, high-speed Casio Exilim FH20 out a train window, then slowed down the results:
He writes,
The ‘trick’ is the camera collects images at a rate of 210 per second – but the film is played back at 30 frames per second. So, every seven seconds of footage that you watch corresponds to 1 real second. At least at the start, one real second is plenty of time for someone to move into, then out of, the camera’s field of view, but isn’t enough time for them to really do much: hence, the frozen effect. It breaks down towards the end not because I’m doing something clever with the frame rates (captured or replayed), but simply because the train was stopping!

Mesmerizing indeed. I find myself seeing an almost 3D effect. Fascinating.
I’m also amazed that the Casio can handle 210 fps with motion and not produce any rolling shutter effects.
Incredible! I will definitely get one for our sports analysis videos. Wonder about the video container format though (AVI)
Either you are being sarcastic calling that $350 camera inexpensive or I have to get you my Christmas wishlist.
That is really cool, but for a truly viral video he should’ve added cool music or something to add to the great visuals. Don’t discount the importance of good audio; look at the Blair Witch Project, Cops or any reality show, people have been trained to watch crappy shaky video, or in this case cool visual images, but with bad or no audio people turn it off. Or not, what do you think?
some peole have added music: http://www.youtube.com/watch?v=dbK2tAjx-4c, http://youtubedoubler.com/?video1=-oMUE1OWvcI&start1=0&video2=az_2oiccZNo&start2=0&authorName=nightanddayman.com, http://youtubedoubler.com/?video1=m1xSa7gcYmU&start1=0&video2=-UJX0QpkhhU&start2=0&authorName=Not+Sure, http://bit.ly/eAUu9r
