Slow Motion W/water

And follow up question, does and why would using a shutter speed above 1/24 give you any crisper a still than shooting at 1/24 when shooting 24p. Wouldn't that just mean the shutter opened for precisely that frame? Or does the shutter open once per frame (so 24x shooting 24p no matter what the shutter speed), but the shutter speed simply determines how long the shutter stays open per its one opening per frame? I think that sounds right?

Do video cameras exist that can handle, for example 500 fps or more? How much do they cost and who makes them?

Check back on page two of this thread, Kevin Brigg's has a link to one (HD).
 
and with a little help from Google, here's the realm of the scientific and BIG budgets:

If you want to get real freaky, how about 5 million frames per second!

..and perhaps more "practical" is the Photron Ultima APX-RS: "..full mega pixel resolution as fast as 3,000 frames per second (fps), a staggering 10,000 fps at 512 by 512 pixels, and the fastest top speed in the industry of 250,000 fps."

You gotta see their video clips, especially the one of a water filled balloon being pierced by an exacto knife at 4,000 fps!

The shutter speed has to match the speed of the action you are filming. I am filming a dance competition this Sunday at 1/120-1/250 shutter 30p. Most sporting events should be filmed in this range. If you were to film NASCAR and get good footage you’re probably looking at closer to 1/2000 or higher. The downside is how dark your exposure will be. With the shutter only open for 1/2000 sec the amount of light is decreased quite a bit. It's better to film footage that is on the dark side rather than too bright, because you can always pull more information from a dark frame, but with a blown out exposure all the information is gone forever. When I film weddings in dark reception halls, rather than getting footage that is too dark I turn down my shutter speed to 1/15 sec. This brightens the footage up a lot, but as a result any quick movements are really blurry. The only solution is more light via an onboard camera light, or shooting in 60i, but I hate interlaced footage. Some times the extreme motion blur is a good thing if you have a shot planned that can utilize it. I am always fiddling with my exposure to find the most pleasing image.

Here is a short basketball clip I posted a while back that has some extreme motion blur that works. I did a manual zoom using the zoom ring 1/4 shutter at 30fps. I had to close the iris more to let less light in to compensate for the extra light coming in from the long 0.25 sec exposure.

Thanks Shawn, I just checked this post today. I have a music video coming up that I might need your help on. I'll PM you when it gets closer to the shoot date.
