As a bird photographer I've noticed this when photographing ducks. My Canon 80D shoots at 7fps and many ducks unfortunately flap their wings anywhere between 7-9 beats per second leading to same-position between shots.
This is not only about syncing with the frame rate. The shutter speed is a real player in this phenomenon. As we see, the video was made by a security camera or something, which means it probably uses some auto exposure method, that includes switching the shutter speed. Shutter speed influences in how much time the camera sensor captures light. This number is usually limited to a half of the frame duration (~1/24 sec, usually). In situations where there is a lot of light, the camera adjusts the shutter speed, sometimes going beyond 1/1000 sec. This explains why the fidget spinner video has the blur - low light situation - shutter speed goes somewhere near 1/50 sec, which means the movement is captured by the sensor inside a single frame.
The same thing can happen with light illuminating a room. When both your machine and the light just take the frequency of the outlet, you can get yourself a pretty dangerous situation, it really looks as if the thing you are looking at is not moving at all, when in fact, it can often have 900, 1800 or 3200 rpm (for 60Hz folk out there), it´s one of the reasons why having multiple light sources with different frequencies in such a room is pretty much a must...
Yes! actually that is a great example and a better "frame sync" effect because it doesn't produce the rolling shutter warping. I think party style strobes do it fairly well too when you crank up the frequency.
The only problem is when the birds in all these odd videos were frozen, none of them had winds to keep it flapping there and even they bird do this in the wing they are not still in a single pinpoint spot and the only thing moving is their head. You can see that everyone standing around obviously see exactly what these phones and cameras do because they are all trying to figure it out. Then the guy who startled the frozen bird with the broom and when it flew off it was obvious it was not frame rate or speed.
The can flap there wings 10-15 times a sec it's a hummingbird. The fps of the camera is 15fps. And it's sincs up. Why are they playing that past??? To be stable as you saw it stayed in one place. Or go online and look up hummingbird
I think everyone's taking this a bit too far, I believe the force of the winds hitting the sides of the house make a constant upward push over the edges of the house. He cups his wings around his body which creates drag and almost like a parachute effect. Which lifts him up or keeps him hovering with time and skill I think birds develop many different tactics of movement that aren't really widely known. Also you can see at the end his feathers get lifted by another gust that kind of spreads through them, he's controlling his body that's all
Looking through a standard chain link fence up at a passing helicopter makes the blades look like they are curved up towards the sky. Do our eyes have a frame rate? No, else helicopter blades would always look strange. So, what is it about the chain link fence that makes the blades look so strange? BTW, at least two people have seen the effect.
Cool. I have a strong feeling what you may be seeing in that situation may be a "Moiré pattern" making the blades bend up 😉 Check it out on wiki. If the blades are strobing also it could additionally be from a "zoetrope" type of effect going on? Two visual phenomena for the price of one.
No, our eyes don't have even an array of pixels - as in a typical camera sensor - so no comparable concept of "frame" let alone frame-rate. Instead our vision process is more organic (messy) eg no "full frame" gets sent, instead some bits of our retina only send signals where there is _change_ (eg motion or contrast or certain shapes) in the field of vision. After that the visual data (such as it is) gets data-compressed to fit within the limited connectivity and bandwidth of the optic nerve. At the receiving (brain) end of that, the brain synthesises and re-edits (eg so no weird effect when blinking or turning your head). The primary (not the only) end product of this messy but highly evolved (or if you prefer, as I don't, designed) data processing chain is the comfortable "virtual reality" image we innocently assume to reflect real-reality. Until we come across optical illusions etc.
Or, or did you see the multiple different footages of birds frozen, that one had to be photo shopped, but I fly macaw so this has really peaked my interest, birds have starved to death while frozen, there's a few where the birds are close to 5g WiFi, but there's also a good few with no power lines, cool I'd love you to be able to film my macaw in free flight, he has a seriously powerful wing beat , he's often hit me with the tips and all I'll say on that is ouch...
2:20 I wouldn’t say that messes with my mind, it’s just looks stupid 😂😂😂 3:08 that rolling shutter tho SuperVinlin 4:55 called it (it’s almost like I’ve gotten SmarterEveryDay ;p [which coincidentally his video on rolling shutters is in the recommend 😂😂])
I like your Love Birds I have a pair in the aviary the same colours. I have Buttercup ( the yellow female ) and Robin Hood ( the green male. I call him Errol because Errol Flynn was the best Robin Hood and he's always in like Flynn ) I have kept one of their hand raised offspring for myself. He was sitting on my shoulder as I am typing this, but is too interested in what I am doing and run's over the the keyboard making it very difficult. I put him back on my shoulder, but he jumps back on the keyboard
Ok. 4 years later, people have caught the very same thing on digital GOOD cameras. And people on the ground in the videos rating to figure out how to help the birds. All over the world. Any ideas on those?
Bird's flap-rate eqals camera's-framerate...SURE, FOOL...exactly and over some seconds...SURE, DREAM ON..."Oh im just so good, im fine....please, please, say that im good, I always can explain everything, no matter if its right...ridiculous...(matching Emoticon not available)
👨💻👍👉whats that camera hack again ? frame rate thing ?? would this frame rate work on a POLITICIAN talking about what there gunna do if elected :) mouth flapping goes still like haaa ! 😁🤳🕴
This is, hands down, the best followup video i've seen yet. Well done man. Glad you enjoyed my floating bird!
Floaty bird man! Thanks for dropping by and checking it out, and for sharing floaty bird with the world!
Wings down
GingerBeard is it you?
As a bird photographer I've noticed this when photographing ducks. My Canon 80D shoots at 7fps and many ducks unfortunately flap their wings anywhere between 7-9 beats per second leading to same-position between shots.
He put the camera at the same frames as the bird flap
Finally someone smart
Or he edited frames where he’s flapping
I believe the flaprate of a bird greatly depends on its mass, wingspan, and action - I'd expect more intense flapping at takeoff than at hover.
This is not only about syncing with the frame rate. The shutter speed is a real player in this phenomenon. As we see, the video was made by a security camera or something, which means it probably uses some auto exposure method, that includes switching the shutter speed. Shutter speed influences in how much time the camera sensor captures light. This number is usually limited to a half of the frame duration (~1/24 sec, usually).

This explains why the fidget spinner video has the blur - low light situation - shutter speed goes somewhere near 1/50 sec, which means the movement is captured by the sensor inside a single frame.
It would have an effect on the appearance of the bird's wing being blurry or not, the position would not be affected because the frame rate is fixed.
The same thing can happen with light illuminating a room. When both your machine and the light just take the frequency of the outlet, you can get yourself a pretty dangerous situation, it really looks as if the thing you are looking at is not moving at all, when in fact, it can often have 900, 1800 or 3200 rpm (for 60Hz folk out there), it´s one of the reasons why having multiple light sources with different frequencies in such a room is pretty much a must...

Birds ride the wind just like fish swim the water.
how do you explaine the dead birds in Air floating??
There one problem, not only are the. It’s wings not flapping but it’s body isn’t moving at all either. I’m still trying to understand this
It’s real just the camera could not keep up with the birds pace of its wings so it looks like it’s not even flying at all
Good to see another video dude! Always enjoy them
Thanks man!
That was really interesting!
Love your sense of humour, and love your wife's laugh! 😅😅
Yeah he really needs to can her laugh, or at least get a sampling of it... it's gold!
It’s real bc I saw one when I was going home my mom did not believe me tho😢

It's called quantum locking.

sparky x
I thought it was 75 times a second
a humming bird can flap its wing 70 times per second
I think everyone's taking this a bit too far, I believe the force of the winds hitting the sides of the house make a constant upward push over the edges of the house.

I think hes Flapping his wings as fast as a like humming bird idk the name
and the camera is just in sync as the bird flapping
I can't wait to see the new content!
You can and will!
It is like the pressure cleaner on spiral,looks like wiggle water.
I was traveling to my cousins birthday when I saw a bird stuck in mid air it was an eagle and an aeroplane
Me and my friend saw a bird today floating in mid air
I mean, it’s obviously not fake because the shutter speed is the same as the wings flapping
Note to self: when faking a video don't forget to add warping.
😆

Looks like somebody forgot to put an animated texture over the helicopter's blades
I guess if we do live in a simulation that could happen.

You guys are cool. Thanks for sharing.
make more debunking videos like this, you're voice is perfect for it!
Also check out "smartereveryday" that guy does some great science stuff, well worth a look.
2:20 I wouldn’t say that messes with my mind, it’s just looks stupid 😂😂😂
3:08 that rolling shutter tho SuperVinlin
4:55 called it (it’s almost like I’ve gotten SmarterEveryDay ;p [which coincidentally his video on rolling shutters is in the recommend 😂😂])
The only bird in the world that can hover in one spot i the humming bird
The bird is just in creative mode.
bahaha
Which camera do you use? Minute 3:00. In your house
Canon 5Dmk4 :)
excellent and entertaining
Ima YEET that bird
Making videos from the car, is that still a thing. [SIGH]
Lovebirds! 💓
Priscilla Graeff their stumpy tail and goofy break is the best.
I like your Love Birds I have a pair in the aviary the same colours. I have Buttercup ( the yellow female ) and Robin Hood ( the green male.

I was goin with a glitch in the matrix
Square up is the term
REAL LIFE
hummingbird? cant tell
Yeah maybe?? Curious though.
I have saw that video
4th dimension
I jave seem a lot fake pnes for sure. I am not crazy
Ok. 4 years later, people have caught the very same thing on digital GOOD cameras. And people on the ground in the videos rating to figure out how to help the birds. All over the world. Any ideas on those?

Somwtjmes they desapair and show from anywhere. Real
This dude is hacking
Itsweird and you can't explain it
First. Forgot about this guy.
Cheers for checking it out.
Sup
yo
Bravo.
OFC ITS FAKE
Im not that famus he said so this wont blow up :)
30 fps (flaps per seconds)
15 actually, same as a House Sparrow's wingbeat rate
@@fylphotography9269 thx for the facts I was just makin a joke .p.
Those moments when your wife tries to match your humor and it's a little cringy :P
I feel you bro. But her laugh is nice.
Boice
Why isn't the girl driving or is there another person driving?
cuz the guy is driving but its hard to tell i found it hard to tell if it was her driving or the guy
If you notice the guy has an accent so they're probably in Europe and Europe has right hand drive vehicles... Where the fuck have you been?
They're in Australia, not Europe. Also, most of Europe uses left-hand drive vehicles, with the exception of UK and Ireland.
the PORNOCHRIST it’s cuz his hands are practically on his lap
👨💻👍👉whats that camera hack again ? frame rate thing ?? would this frame rate work on a POLITICIAN talking about what there gunna do if elected :) mouth flapping goes still like haaa ! 😁🤳🕴
WTF!??!?!!? Is your car a tesla or an bmw or so or why she can tip on her mobile when she is drifing!?!?!?!?
