Spent a Few Days with the Phantom Camera

[iacas]

The Phantom camera can record at 40,000 frames per second (the model we had), but we recorded virtually everything at 11,000 frames per second because the resolution (1024 x 512) was pretty good.

We were mostly using it to verify the Flightscope's measurements (freaking spot on man, no shots outside of 0.5° off, and 90% within 0.25°), but we had some time to "goof around" a bit later on... ;)

Here are two flop shots (three to five frames apart, I think) that I thought you might like. Yes, the ball is levitating. :)

P.S. The club is a frame or two or three away from making contact with the ball in the second and fourth images, BTW.

We use the yellow balls to denote the ones we have the little stickers on. The little metallic stickers help radar machines more accurately measure spin when they have only 35 feet or so to measure it.

The phantom is such a cool camera. Will you be sharing more details about what you learned later on?

I would love to see some full videos, close-up and full shots. Looking forward to the day those kind of specs become affordable.

We didn't have the lighting for that. Shutter speeds of 1/20,000 require a heck of a lot of light, especially if you want an aperture smaller than f/1.8. :)

And the files would be about a hundred GB and it would take almost 14 minutes to watch a full swing. :)

We didn't really do anything to learn, we just wanted to shoot some cool video. Nothing we didn't already know.

We shot videos to re-do the ball flight laws video in higher speeds and higher resolution, but the camera wasn't directly overhead on the left-path-right-face ones so as the ball gains altitude it looks like it's going closer to the path than is accurate. :P

Here's a still from the video of a putt:

This is totally awesome

How much light did you have to you have for these videos?  They seem dark, but I assume you had a lot of light?  I did a similar video last winter with my Casio Ex-FC100 and 210 fps and I needed a really bright photography light.  It was still grainy.

Did you film anything goofy like a glass breaking or egg cracking?

It's an f/1.8 lens at about 1/20,000 shutter speed...

Just a little work light. But really pretty close to the filmed subject area...

Nerds unite! We want the 14 minute full swing video MEOW!!! :D

For Beachcomer, Nerd analysis:  "At time point 11:37.003 notice how Dave's left index finger knuckle rotates 0.113 mm to the left as impact is initiated."

LOL can you imagine the discussions?!?
