Slow Motion Rebounding Test

Well, I have my new Casio EX-F1, and I just *love* it, especially the high speed video (which makes slow motion playback possible).
I'm still experimenting with how to work it best. One thing I learned is if you are going to do slow motion, you need strong, steady light. In any case, I took the following rebounding video two days ago, May 7th, at 300 frames per second.
Obviously, many things could be improved here: it would be nice to lose the vignette, but I needed the wide-angle; the light is still intermittent; the focus could be a little better; and somebody get me a gorgeous and enthusiastic model so I'm not always the focus here. ;-)
But still, I think the kind of "time microscopy" made possible here will enable me to further understand and breakdown the mechanics and energetics of rebounding. For example, I think this video helps make somewhat clearer how the arms and shoulders come into play on the downward trajectory on a medium-high bounce like this one.
Do let me know if you have any questions or comments. I'm still hoping to get a much simplified rebounding manual out this year.

That was COOL! It's amazing to see the whole thing so slowed down. I especially enjoyed how the springs stretch!

Hi Susan. Thanks so much for your comment. Just a quick correction: this top-of-the-line imported unit uses bungy-bands, not springs, which makes it even nicer in terms of the quality of the bounce!
