German scientists have been awarded a Guinness World Record for “fastest movie” after successfully capturing two images of an X-ray laser beam 50 femtoseconds apart. One femtosecond is equal to one quadrillionth (or one millionth of one billionth) of a second. Here’s some science talk explaining it:
[…] the scientists split the X-ray laser beam into two flashes and sent one of them via a detour of only 0.015 millimetres, making it arrive 50 femtoseconds later than the first one. Since no detector can be read out so fast, the scientists stored both images as superimposed holograms, allowing the subsequent reconstruction of the single images.
With these experiments, the scientists showed that this record slow motion is achievable. However, they did not only take the world’s fastest but probably also the shortest film – with just two images. Thus, additional development work is necessary for the use of this method in practice. [#]
Here’s an interesting look at the amazing camera being developed at MIT that shoots a staggering one trillion frames per second — fast enough to create footage of light traveling:
[…] the researchers were able to create slow-motion movies, showing what appears to be a bullet of light that moves from one end of the bottle to the other […] Each horizontal line is exposed for just 1.71 picoseconds, or trillionths of a second, Dr. Raskar said — enough time for the laser beam to travel less than half a millimeter through the fluid inside the bottle.
To create a movie of the event, the researchers record about 500 frames in just under a nanosecond, or a billionth of a second. Because each individual movie has a very narrow field of view, they repeat the process a number of times, scanning it vertically to build a complete scene that shows the beam moving from one end of the bottle, bouncing off the cap and then scattering back through the fluid. If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years. [#]
They believe that the technology may one day be useful for medicine, industry, science, or even consumer photography.
Fast Burst Camera is a best-selling Android app that upgrades your phone camera’s FPS to 5 to 10 frames per second, allowing you to capture action shots by spraying, praying, and selecting the best image afterward. On high end phones, the FPS can even go up to a crazy 30FPS. Like with the burst mode on DSLRs, holding down the shutter will fill up your buffer, and you’ll need to wait for it to clear before continuing. The app can be purchased from the Android Market for $3.63.
Warco — short for War Correspondent — is an upcoming video game in which the player takes on the role of a journalist named Jesse DeMarco. Despite being classified as a first person shooter, the objective is to shoot people with a camera rather than a gun. After venturing into dangerous conflicts and risking your life to snag some footage, you’re given the task of editing the video into a compelling news story. It almost seems like a Pokemon Snap game for adults. If they went a step further and made an online multiplayer mode, that’d certainly be… interesting.
Shooting 4.5 million frames per second of molecules using an x-ray flash is impressive, but can non-scientific cameras come anywhere close? The answer is yes: Vision Research has a new Phantom high speed camera called the v1610 that can capture footage at a whopping 1,000,000fps. Granted, the resolution needs to be a paltry 128×16 for that fps, but at a full 1280×800 it still shoots at 16,000fps. To give you an idea of what 1 million fps is like, consider this: 1 second of the footage will provide you with 9.25 hours of uber-slow motion 30fps video.
Having a camera that shoots 5000 frames per second is enough to capture slow motion footage of a bullet flying through the air, but scientists at the Science and Technology Facilities Council have now announced a camera that shoots a staggering 4.5 million frames per second. Rather than bullets, the camera is designed to capture 3D images of individual molecules using powerful x-ray flashes that last one hundred million billionth of a second. The £3 million camera will land in scientists hands in 2015.
We often share cool slow motion or time-lapse videos here on PetaPixel, but this video is a bit different. YouTube user brusspup uses a turntable spinning at 45RPM to create amazing optical illusion animations. To a human eye look at the turntable, everything looks like a blur, but record it at 24 frames per second, and amazing animations appear!

The images of the guy jumping is me. I recorded myself jumping in the living room then took 30 frames from that footage and traced the images in photoshop and filled with black. Then printed out the 30 images and cut each one out. I used 30 wooden blocks and glued them to a piece of construction paper then taped the images of the jumping guy to the clear sheet and aligned them with the blocks.
Google just released the latest beta version of its Chrome browser, and created a pretty amazing video to demonstrate how fast pages load. Using a Phantom v640 high speed camera, they film the browser racing random Rube Goldberg-style contraptions at up to 2700 frames per second. For example, in one test Chrome races a potato gun. Sweet.
They also have a cool behind-the-scenes video showing how the tests were done. I can’t believe it took 51 takes to get the potato gun shot to come out right.
