Cool new slow motion video technique.

    Combining 'Bullet time" from the matrix movies with relatively inexpensive Chronos Slow Motion Cameras a new version of high definition slow motion photography is now possible. Here is the second video by a group using this novel set up:

    Please note, that just like in the Matrix the camera does not rotate around what is being shot. They have a ring of high speed video cameras and by taking one frame from each one sequentially they are able to create an even higher artificial frame rate. The result is that the object being photographed looks like it is spinning. In this video they chose an object that was already spinning and synced the sequence of camera shots to the speed of the rotating object. As a result the spinning object appears to be roughly stationary.

    I like these folks. That's a clever setup.

    Thanks for explaining that-- I was wondering how on earth they could "spin" such a large array of cameras, and of course-- they are not. It's a sequential triggering of the "shutters". Brilliant and clever use of tech. I love that they need 72 gig networking... ;)

    I have always liked the Hydraulic Press channel, and their spin-off, Beyond The Press. Many interesting videos by that couple.

    I'm unfamiliar with the other guys, but I'll be checking out their videos too.

    Okay, they have started a new channel with 72 chronos slow motion cameras. They explain a bit more in this one, which is also an amazing photo analysis of how a flame front propagates in self-oxygenated flammable gas. I could easily see a scientific paper on the subject myself. Even though this is just for fun? Imagine with measuring instruments and whatnot. I doubt humans have seen this before.

    I know, quite the accomplishment for amateurs. And yes, a whole new channel devoted to this tech. It was not a cheap investment. And I guess the light, at least for the indoor one, is so strong that they need to wear very dark glasses and the heat from even LED's builds up at very quickly. Could you imagine attempting that with old fashioned incandescent lamps?

    The two water balloons looked-- for an instant-- like two colliding planets. (as I would imagine what that might look like).

    Reality is always more interesting than imaginary. :)
