That was mesmerizing. I thought, "I'll only watch two minutes of this, it's going to get dull", then, "Only five minutes," then I finished it. It was almost hypnotic. I especially liked the flat-point bullet going through the paper target and taking out the perfect circle of paper along with it. Destruction is an artistic statement.

Lets do some maths to see if this is 1 million fps

1'000'000 hz, presumably played back at 30fps... though it could be played back at 24, 25 or even 60fps, I'll assume 30fps for now as a median result.

1'000'000 / 30 = 33'333

therefore bullets should will appear to be going 33'333x slower than they actually are.

Considering how thick a piece of metal these bullet penetrate, I suspect they are very high velocity so about 3500 feet/sec = 1050 meters/sec

1050m /sec = 1'050'000mm / sec

1'050'000 / 33'333 = 31mm

bullets should appear to be going 31mm per second or just over 1 inch per second. Looks to me like those bullets are travelling about 1 inch per second.

Conclusion: This probably was recorded at 1'000'000 frames per second

And when you look at the site itself (kurzzeit.com), they're manufacturers and sellers of high-speed cameras, Real Time Trigger Systems, ultra-high powered flash-lights (3,000W bulb, anyone?) and all the other paraphernalia that makes up high-speed bullet photography.

You also realise that the shots in that movie are at a range of speeds - from 250,000 fps to 1,000,000 fps. They've got a comparison on the website of a 1,000,000 fps bullet impact to a 500,000 fps one...

It's also interesting to read about the cameras that take these shots - they're of a necessity low-resolution (The Shimadzu HPV-1 is just 312x260) due to the ultra-high speed of the capture (I suspect they actually use a higher resolution CCD, and phase-read the inputs so that they capture only a percentage of the available sensor space each frame...)

OK, enough waffling - I just wanted to point out that the 1,000,000 fps is backed by facts and suchlike, not a figure that's been pulled out of someone's derrière.
1,000,000 is nothing. Specialised Imaging Limited has made a camera that can take 200,000,000 fps [http://en.wikipedia.org/wiki/High_speed_photography#CCD]

Now that is cool, though I have to say I was more impressed by their trajectory tracker app - showing bullets in flight, and tracking them (Especially when you can see the little counter ticking up the hundreds-of-thousandths of a second passing) as they fly is some awesome tech.
