Dives of the Kingfisher in Slow Motion

Nature does its thing so quickly sometimes that you have to slow it down to appreciate the beauty and power of it. This is a video of a kingfisher plucking fish out of the water, with views from both above the water (which catches the dive and takeoff) and below the water (which shows the efficient grab of the fish). The underwater view is amazing…I’d never seen that before.


A Cheetah Running in Slow Motion

I don’t know that there’s much to say about this…it’s the world’s fastest land animal moving in slow motion, muscles rippling, legs moving in concert, etc. It’s beautiful and mesmerizing β€” time kinda stopped for me while I was watching it.


Slow Motion Helicopter Blade Rotation

Here’s what a whirring helicopter blade looks like, from the perspective of a GoPro strapped to the blade. The video is in slow motion β€” shot at 240 fps and displayed at 30 fps. Here’s what the blade looks like in flight and upside-down while doing a flip. (via clive thompson)


Fuzzy Moths Taking Flight in Super Slow Motion

In trying to explain what you’re about to see here, I cannot improve upon the Dr. Adrian Smith’s narration at the beginning of this video:

But sometimes I think the most useful thing I can do as a scientist is to point the fancy science cameras at some moths flapping their wings in front of a purple backdrop. I mean, whose day isn’t going to be better after watching a pink and purple rosy maple moth flying in super slow motion? This is a polyphemus moth, a gigantic species of silk moth. What you are seeing, like all the rest of the clips in this video, was filmed at 6,000 frames per second.

Most of the moths in the video are delightfully fuzzy and chonky β€” if these moths were birds, they’d be birbs. Shall we call them mopfs?

The rest of Smith’s AntLab videos are worth looking through β€” I’ve previously posted about his slow motion videos here. (via aeon)


Simone Biles, Mesmerizing in Slow Motion

Gymnast Simone Biles won her 7th US Gymnastics Championship this past weekend, further cementing her status as the world’s best gymnast and one of the most dominant athletes of all time in any sport. In her floor exercise routine on the first day of the competition, Biles absolutely nailed a triple double β€” that’s three twists while doing two backflips. Timothy Burke took the footage and slowed it down so that we can see exactly what’s going on in the air. And, Jesus, I was NOT prepared for what I saw. The two handsprings that set up the final move are beautiful slowed down, leisurely even. But then Biles launches herself impossibly high into the air β€” like absurdly and spectacularly high β€” and starts twisting and flipping at a speed that seems fast even for slow motion. And the landing β€” it’s like she was standing there all along, waiting for the rest of her spirit to join her. Watching the routine at regular speed makes you appreciate the move even more.

In reaction to this move, NBA head coach Stan Van Gundy, who has seen his fair share of elite athletes doing amazing things over the years, exclaimed: “How is that even humanly possible?” As if to preemptively answer him and everyone else watching, the sparkly leotard that Biles wore during her routine had a picture of a goat sown into it because she is the GOAT.

Update: Physicist David Young analyzes Biles’ triple-double:

Assuming her rotation rates around each axis remain constant, to get three full flips in would require an extra 0.65 seconds, which requires a launch speed of 22.6 miles per hour, all other things being equal. This is not possible, even if we assume her max launch speed is 18 miles per hour, which is apparently her top sprinting speed.

However, if she could do three full flips, she would also be able to get in one-and-a-half more twists at her current rotation rate! What would this even be called?! What might be more likely would be to try to gain an extra half twist so that she would take off facing left and land facing right, still only completing two full flips.

Ultra Slow-Motion Video of Insects Taking Flight

Research biologist Adrian Smith, who specializes in insects, recently filmed a number of different types of flying insects taking off and flying away at 3200 frames/sec. Before watching, I figured I’d find this interesting β€” flying and slow motion together? sign me up! β€” but this video was straight-up mesmerizing with just the right amount of informative narration from Smith. There’s such an amazing diversity in wing shape and flight styles among even this small group of insects; I had to keep rewinding it to watch for details that I’d missed. Also, don’t miss the fishfly breaking the fourth wall by looking right at the camera while taking off at 6:07. I see you, my dude.

Smith has previously captured flying ants in slow motion and this globular springtail bug that spins through the air at more than 22,000 rpm. (via moss & fog)


Watch Popcorn Popping in Super Slow Motion (100,000 fps)

Popped popcorn kernels are like snowflakes: no two are alike. If you watch popcorn popping at the ludicrously slow speed of 100,000 fps, you can see these individualized forms flowering into existence. Pro tip: turn off the upbeat music on the video and supply a mellower soundtrack of your own β€” slow motion video requires meditative music.

How Slow Motion Works

The kids and I were talking about how slow motion video works the other day, so I was happy to see this new video from Phil Edwards detailing how the technique works and its history in cinema, from Eadweard Muybridge to Wes Anderson and from Seven Samurai to The Matrix.

I am an unabashed fan of slow motion; you can check out dozens of slow motion videos I have posted over the years, including this video of Alan Rickman dramatically drinking tea.


Dinnerware Smashing in Slow Motion Accompanied by Bach

Optical Arts conceived this video as a “live action musical animation” of cups, plates, and glasses smashing and un-smashing accompanied by the toccata section of Johann Sebastian Bach’s famous organ piece, Toccata and Fugue in D Minor. I thought it was fully CGI at first (as The Morning News reported), but then I found the making of video on the project page and it’s not β€” they filmed all the glasses and dished smashing at extremely high speeds between 1000 and 5000 frames/second on Phantom cameras.

I don’t know about you, but this video is what it looks like inside my head lately. Smash smash smash! (via the morning news)


Slow Motion Ocean

MOCEAN is a mesmerizing short film by cinematographer Chris Bryan of ocean waves crashing and surging in slow motion.

The feeling of jumping off the rocks in the dark by myself just to capture the very first rays of light hitting the ocean without another sole in sight is unexplainable, its one of the most amazing feelings ever, its like my own personal therapy.

Bryan worked as a cinematographer on the BBC’s Blue Planet II. Distracting URL watermark aside, I could have watched footage like this for another hour, especially of waves from underneath the water.


The Surprising Grace & Power of a Slow Motion Pigeon Take-off

In this slow motion video clip from a BBC program called Secrets of Bones, you can see how a pigeon takes off so quickly. Pigeons can accelerate from 0 to 60 mph in about 2 seconds, straight up from the ground. A look at its skeleton reveals short, thick bones, an absolute necessity for an animal generating that much power in such a short time. (via the kid should see this, back from its summer hiatus)


This AI Makes High-Quality Slow Motion Videos from Regular 30 fps Video

NVIDIA trained a deep learning framework to take videos filmed at 30 fps and turn them into slow motion videos at the equivalent of 240 or even 480 fps. Even though the system is guessing on the content in the extra frames, the final results look amazingly sharp and lifelike.

“There are many memorable moments in your life that you might want to record with a camera in slow-motion because they are hard to see clearly with your eyes: the first time a baby walks, a difficult skateboard trick, a dog catching a ball,” the researchers wrote in the research paper. “While it is possible to take 240-frame-per-second videos with a cell phone, recording everything at high frame rates is impractical, as it requires large memories and is power-intensive for mobile devices,” the team explained.

With this new research, users can slow down their recordings after taking them.

Using this technique and what Peter Jackson’s team is doing with WWI footage, it would be interesting to clean up and slow down all sorts of archival footage (like the Zapruder film, just to choose one obvious example).


A powerful video of every concussion in the NFL this year

Data artist Josh Begley edited together a 5m30s video of every concussion suffered in an NFL game this year. I was barely able to get through this…I had to pause a couple of times. From an article about the video at The Intercept:

The NFL has done a masterful job at mainstreaming the violence of the game, so that fans and spectators don’t feel too bad about what’s actually happening out there. No single word has protected the NFL from the true costs of this violence more than “concussion.” That word puts a protective barrier between us and what’s really going on out on the field.

It’s not a headache. It’s not “getting your bell rung.” You don’t have a bell. It’s a traumatic brain injury. Every single concussion is a new traumatic brain injury. In addition to the torn ACLs and MCLs, in addition to all of the horrible broken bones, the NFL diagnosed at least 281 traumatic brain injuries this season. And no document has ever quite displayed the horror of it all like “Concussion Protocol,” a film by Josh Begley and Field of Vision.

The backwards slow-mo technique is a bit off-putting at first, but as Greg Dorsainville noted in the video’s thread:

If it was in forwards it would be like any big hits package you see in an espn highlight show where we celebrate the football and hit and not mourn the result of the moment: a human in pain, disorientation, and slowly killing themselves.

Having big second thoughts on watching the Super Bowl this weekend, karma offsets or no. (via @harmancipants)


Hummingbirds flying in slow motion

Slow Mo Hummingbird

National Geographic photographer Anand Varma recently took some slow motion videos of hummingbirds in flight. Incredible footage. It always amazes me how still their heads and bodies are while their wings beat furiously. Here’s National Geographic’s feature on using high-speed cameras to uncover the secrets of hummingbird flight.

World’s smallest birds is just one of several distinctions that hummingbird species claim. They’re the only birds that can hover in still air for 30 seconds or more. They’re the only birds with a “reverse gear”-that is, they can truly fly backward. And they’re the record holders for the fastest metabolic rate of any vertebrate on the planet: A 2013 University of Toronto study concluded that if hummingbirds were the size of an average human, they’d need to drink more than one 12-ounce can of soda for every minute they’re hovering, because they burn sugar so fast. Small wonder that these birds will wage aerial dogfights to control a prime patch of nectar-laden flowers.

Fun facts: some hummingbirds can beat their wings 100 times in a second and can sip nectar 15 times per second. I also like the locals’ name for the Cuban bee hummingbird, the world’s smallest bird: zunzuncito (little buzz buzz).


The rolling shutter effect explained

When your phone takes a photo of something, it scans the frame of view line-by-line from top to bottom quickly. But, if you’re photographing an object like a fan or plane’s propellor that’s moving very quickly, the scanning exposure can warp the final image. That’s the rolling shutter effect. Using high-speed camera footage to simulate the warping, Smarter Everyday shows us exactly how the rolling shutter effect occurs. The guitar strings are the coolest; more of that in this video:

P.S. Here’s the behind-the-scenes for Smarter Everyday’s rolling shutter video.


The swirling beauty of colored ink in water

Macro Room, which has previously brought you close-up shots of melting ice cream and pills dissolving in water, recently filled an aquarium with water, shot various colors of ink into it, and filmed the swirling beauty in close-up slow motion.

P.S. It’s worth sitting though the bro-y thanks portion of the video to get a glimpse of their lo-fi rooftop setup. Did they shoot all that on a phone?


How the BBC made Planet Earth II

In the first of a three-part video series, Vox’s Joss Fong looks at how the technology used to film nature documentaries has changed over the past 50 years and how the producers of Planet Earth II used contemporary image stabilization techniques to make the series with a more cinematic style.

In the 1970s and ’80s, it was enough for the NHU to show people a creature they’d never seen before and provide the details in the narration. The films were illustrated zoology lectures. Since then, the producers have become sticklers for capturing specific behaviors, and in Planet Earth II, they showcase the drama of those behaviors. Each scene sets up the characters to perform something - something brave, something brutal, something bizarre. They’ve made room for our emotions; that’s what cinematic storytelling means.

And visually, the cinematic approach means the camera is often moving.

Hollywood filmmakers have kept the camera in motion for decades, but for obvious reasons, it’s much more difficult when your subject is wildlife. As we explain in the video at the top of this post, NHU producers used new stabilization tools throughout the production of Planet Earth II to move the camera alongside the animals.

The program doesn’t make you wait long to showcase this new approach. The tracking shot of a lemur jumping from tree to tree is one of the first things you see in the first episode and it put my jaw right on the floor. It’s so close and fluid, how did they do that? Going into the series, I thought it was going to be more of the same β€” Planet Earth but with new stories, different animals, etc. β€” but this is really some next-level shit. The kids were more excited after watching it than any movie they’ve seen in the past 6 months (aside from possibly Rogue One). The Blu-ray will be out at the end of March1 but there’s also a 4K “ultra HD” version that had me researching new ultra HD TVs I don’t really need.

Oh, and remember that thrilling sequence of the snakes chasing the newly hatched iguanas? Here’s a short clip on how they filmed it.

Update: The second video in the series is an ode to the BBC’s pioneering use of slow motion and time lapse photography in their nature programs.

Fong also explains one of my favorite things to come out of the first Planet Earth show, the slow motion buffer capture system used by the crew to catch great white sharks leaping out of the water.

But also, digital high-speed cameras came with a continuous recording feature. Instead of pressing a button to start recording and then pressing it again to stop, they could press the button as soon as they saw some action, and the camera would save the seconds that happened before the button was pressed. That’s how the cameraman captured this great white shark coming out of the water, not just in the air, for this sequence in the 2006 Planet Earth series.

I hope the third program is on sound, which has been bugging me while watching Planet Earth II. I could be wrong, but they seem to be using extensive foley effects for the sounds the animals make β€” not their cries necessarily, but the sounds they make as they move. Once you notice, it feels deceptive.

Update: The concluding video in the series shows how the filmmakers use thermal and infrared cameras to capture scenes at night.

The bit at the end about the Sony a7S is interesting β€” as cameras go, this one is much cheaper than the professional high-def cameras used for most of the scenes but is way better in low light.

  1. I still have a Blu-ray player than I barely use and only buy 1-2 BR discs a year, but Planet Earth II is one of those increasingly rare programs you want to see in full HD without compression or streaming artifacts.↩


The chemistry of matches (in super slow motion)

With amazing super slow-motion footage of a match head starting to burn as a backdrop, this video explains the chemical reactions involved in lighting a match.

When the match is struck, a small amount of the red phosphorus on the striking surface is converted into white phosphorus, which then ignites. The heat from this ignites the potassium chlorate, and the match head bursts into flame. During manufacture, the match stick itself is soaked in ammonium phosphate, which prevents ‘afterglow’ once the flame has gone out, and paraffin, which ensures that it burns easily.

Fire tornado in super slow motion

The Slow Mo Guys lit a bucket of kerosene on fire, surrounded it with 12 box fans, whipped the fire into a tornado, and filmed it with slow motion cameras at up to 2500 fps. I don’t know about you, but I want quit my job, say goodbye to my family, give this mesmerizing rotating fire all of my money, and follow it around the world, doing its bidding. (via colossal)


How bow-tie pasta is made…in slow motion

From Zerega Pasta, a video that shows, in slow motion, how farfalle (aka bow-tie pasta) is made at their factory.

Incredible combination of precision and quickness.


Slow motion lightning

Slow motion video of a South Dakota lightning storm shot at 2000 fps.

I love the little tendrils “sent out” by the clouds before a big strike happens. It’s like nature is searching for the optimal path for the energy to travel and then BAM!


Tennis serve in slow motion

At 6000 fps, you can see just how much the racquet flattens a tennis ball on the serve.

Slow motion candle magic

If you hold a lit match an inch or two over the smoking wick of a recently extinguished candle, the candle will light again. If you record that happening with a high speed camera and then slow it way down, it gives you some clues to how that happens:

Hint: wax is a candle’s fuel and smoke is wax vapor… (via digg)


4K dreamtime

Technically, what you’re looking at here is a video shot in 4K resolution (basically 2x regular HD) and at 1000 frames/sec by a Phantom Flex 4K camera which retails for $100,000+. Skateboarders ollie. Dirt bikes spray dirt. Gymnasts contort. Make this as fullscreen as possible and just sit back and enjoy.

My favorite bits were of the gymnasts. In super slow motion, you can see how aerial flips are all about getting your head down as quickly as possible, then snapping your legs around as your head stays almost completely motionless β€” like a chicken’s! Mesmerizing.


Slow motion CD spinning

From the Slow Mo Guys, a video shot at 170,000 frames/sec of a CD shattering after being spun at 23,000 RPM. Worth watching until (or skipping to) the end to see exactly how the disc fractures.

Slow Motion Surfing

You know what’s pretty? Big waves and surfing in slow motion. Take a break and relax at 1000 fps with this mesmerizing video.

The Hans Zimmer soundtrack only adds to the effect. (via β˜…interesting)


New York streets in beautiful slow motion

This starts out ordinarily, but give it some time…it gets really good around 90 seconds in. The combination of panning and slow motion creates a powerful sense of energy around almost-still imagery; it’s a trippy effect. See also James Nares’ Street. (via subtraction)


Slow-mo skateboard tricks

It turns out that this close-up video of slow motion skateboard tricks is all I’ve ever wanted out of life.

I had no idea that’s what they were doing down there. It’s a symphony of footwork!
