Casio EX-F1 ... does up to 1,200 fps ... but at increasingly smaller file sizes.

Too bad these aren't more common... You can see the driving mistakes (or lack thereof) so much more easily.

$700 ... the next high speed camera up from that is the Phantom ... which cost's about a 100 times more.

Actually ... Casio has a newer, cheaper model that isn't quite as capable ... besides their pocketable point and shoot slo mo varieties ... that might not have long enough lenses?

Hmm... may have to put that on the purchase list for work. I can see many reasons to have it... but then again, it's only a matter of time for Canon to catch up....

Awesome! Reminds me of when they were showing the F1 cars in slow motion, there was what seemed like a ton of flex as they were going over the curbing. But then you realize how small of a time frame is shown haha. Vid (scroll down a bit):

Canon COULD do it ... I would welcome being able to use my lenses on a hi-speed Canon DSLR motion capture device, but it's pretty specialized. Like you say ... just a matter of time.

This Casio will do 1,200 fps ... but produces a pretty small format. I should try to do some shots just because we can.

Here's Karen releasing an arrow at 1,200 frames per second ... see how the arrow whips around. A properly stiff arrow will bend around the raiser so that the feather fletches barely touch the raiser. Here the vanes are whacking the raiser pretty hard ... causing the arrow to land far right at 20 yards.

Wow, those videos are great. I can see how the Evo schools could make great use of that - especially the bit when Tom Berry is going through the slalom.

Watching the video... watch his hands on the wheel and the amount of delay there is in the steering when the steering rack actually catches up....

*yikes*

They have a viscous in the center and rear. All Subarus from the last 20 or so years have at least a viscous center, mind you, so that's nothing special. And the rear viscous diff is pretty weak and would have no effect on the front and rear axle speed differences.

I suspect that this video shows all four tires spinning at the same time because of a suspension/tire difference from your car. If you're on stock struts and less sticky tires, you're going to have a lot more front wheel lift that makes it much easier to spin them as the rear squats down more quickly. Also, once the fronts start to break free, they'll be able to continue much more readily, but if they don't get a chance, then all tires should spin about evenly.
