They're really nice. I didn't even notice the propellors until I read a comment about it. The guitar watermarks are a little distracting but it didn't bother me. I understand the necessity of it.
If it wasn't for the freebooters, he wouldn't have to do any of it. You have to imagine the pain he must feel when all of his awesome stuff gets freebooted.
I was so confused why a seemingly random propeller had his trademark until he cut to the head-on where I realised it was photo-shopped onto it. Definitely great work.
So happy to see the scientific community supporting each other on this platform. Ya'll are leading the way to a smarter world, keep up the amazing work!
You can count the frequency of the guitar strings using the rolling shutter! Given that you shot 30fps, it means each frame has span of 1/30s. At 4:08 you can count 7 waves on one of the strings. It means it vibrated 7 times in 1/30s -> 210 times in a second giving 210Hz which should correspond to note G#3 :) I am now interested if it would make sense to make use of it for tuning the sound.
Ah yes, I understand that. My train of thought was something like.. knowing that I can manually choose my shutter speed.. and let's assume that we can set it in such a way that we can diminish the result of the readout speed. In that situation we can calculate by the deformation of the image, and knowing the true image dimensions by design, how 'fast' something is going.
It's really smart to put watermarks on the most amazing parts of the video so it doesn't get stolen I don't think I've seen that yet but it's a great idea
videos cannot be stolen as they are not tajen from the original owner (meaning he doesn't lose it) videos can be pirated but piracy is not the same as theft personally I don't mind the watermarks if they are placed cleverly like in this video however if they are placed obnoxiously like in the channel fullmag yeah that is just annoying since the watermarks cover up what im trying to see

I tried reading about rolling shutter few months back, did not really understand it completely. But, I understood it very well after watching this video. I am amazed by the level of hard work you put in to each video and every video has so much content and crispness to it. I appreciate your effort
Venkatesh Rajendran TV and monitors do the same thing. it's refresh rate. It's how fast pixels can change. Line by line or every other line. If a camera and a screen have the same refresh rate them you have smooth recorded screens. If they do not then you can see the refresh rate. Often used in hertz or specific impulse.
If someone interested, AE effect what he was talking about is called *Time Displacement* 1. Make solid, add default Ramp effect, precompose with moving all attributes. 2. Add Time Displacement and set that precompose of ramp as map. 3. Change resolution of Displacement to height of your video (gonna render very long, but that's the best result, low this value if you wanna make faster render, 1/3 of height look pretty okay). 4. Waste a lot of time to render this on your potato.
This is also the effect that's used for the "Photo Finish" photographs of bike races and other races. The rolling shutter essentially shows a time line across the finish line. Bike spokes get distorted in those images too. Awesome video. Thanks.
Destin! You did a great job with your ad for audible at the end. Usually I just skip the end ads but since you had such funny content I stayed and watched. Great job!
Also the watermarks were not intrusive to the quality of the video, which I imagined was something you were worried about. Lastly great job on making this video interesting and not too long. You fit the content out, in other words the video seemed well paced.
Destin, could you explain why you can actually view "The wagon wheel" or "pinwheel" (The phenomenon that makes a spinning object look like it's slowing down and then it seems to change direction) happening with your bare eyes? Thanks!
If you got the speed of when the wagon wheel effect started to happen and you got the fps of a camera where the same effect happened at the same time, you could get the fps of your eye (I think). Correct me if I'm wrong.
Byte11 I'm fairly certain it happens then the spinning of whatever matches the frequency of the light you're under. So if you're in a house using a fluoro you'll see it according to the frequency of the light (which is also why broken fluoros cause headaches [their frequency is often slower] as opposed to under sun-light. I've actually heard of workers loosing fingers in the 1900s because a circular saw would spin at the same frequency of the factory lights, leading to the illusion that it wasn't on (obviously too much noise in the factory to tell its on using your ears).
Steve Young I am not sure what phenomenon is called the wagon wheel effect but what you described is exactly what happens with my LED lights that run at 50Hz (European grid) pointed at my PC case exhaust fan. it looks like it is turning slower with the LEAD lights on.
I probably could've explained it a little better, but the phenomenon that makes a spinning object look like it's slowing down and then it seems to change directions. Going to add this to my main post as well.
Here is something cool and (somewhat) similar you can do easily at home: Take a fidget spinner and view it being spun under different light sources such as LED, incandescent, fluorescent and natural light. These all have different frequencies the light is flickering at (short of natural light) which causes different visible patterns among the rotating fidget spinner. Since vision is only light reflecting off of an object and being interpreted by our eyes, changing the light source, or differing frequencies, will create a different pattern on the fidget spinner (or other similarly moving objects).
Absolutely outstanding video! I wrote an article eight years ago, so I wouldn't have to answer the question about photos of golf swings with ridiculously bent shafts. If your video were around back then, I would not have needed to write it. Thanks.
Destin, I was watching a couple of your older space videos and I would like to inform you that my grandpa work on the landing module for Apollo 11. He helped design the legs of the module so when it hit the moon it didn't bounce up into the air, I just wanted to tell you, thanks for reading
I subscribed just because you said "no big deal" my subconscious told me to subscribe because you look like a nice guy and make these videos for people to enjoy.
The easiest ones to spot are on the close up footage of the screen. Notice that there's "Smarter Every Day" written in a mostly transparent font? That's watermarking. It protects images/video from being stolen.
Ariq Fauzan idk, but i think a single shot is better because phone cameras now adays are shooting at a faster fps , try doing it with an older camera, i took mine with nokia 5800 express music
I always wondered what kind of RUclipsr would be the one saying it wouldn't be a big deal not subscribing to his channel.... Now I know, those are the ones who already have tons of subscribers and their content is so interesting that it keeps you glued to the screen no matter how long the video is. This channel fits that profile and I've watched every single video without being subscribed to it....
+SmarterEveryDay Destin, the section of this video where you were showing the rolling shutter effect of the guitar strings, were we actually seeing the "notes" in sound wave form of those strings as they were vibrating? Can you show that same footage side by side with an Oscilloscope so we can compare it to "video" of sound waves? (I hope this makes sense 🤔)
Pub x Stompa you can see the vibration of the string, the sound waves are obviously invisible^^ i guess the string is passing the vibration on to the air...but on the other hand low noises have a wavelength of up to like 20m, so that can't work like that^^
I'm pretty sure it's just an artifact of the shutter frequency combined with the strings' vibration frequencies. There's math behind it, but the picture doesn't represent anything meaningful other than looking funky I don't think. As a side note, a perfect sine wave sounds like a ringing noise. You can get apps that will produce it for you. Different instruments sound different because the noises they produce are actually a combination of frequencies overlaid together. Different materials resonate in different ways producing distinct combinations. I took a signals class and only scratched the surface, it's really fascinating stuff.
Which is why there is no such thing as real time. All things have delays in processing a continuous moving image. During the delay for processing no more data is being processed from the sensor (eye or CCD for that matter). The data can be stored (if the storage process is fast enough) and analyzed later (sometimes within microseconds). Great video!
4:53 Notice variations from sin wave forms; subharmonics & interplay from other strings transmitted through the bridge may explain this. Two possible uses of this rolling shutter are better design of string instruments, and better tuning. Sometimes the best tools are those for which they're not intended! Creative people should pay attention to the value of trying out the weird approaches! That's how one gets SmarterEveryDay!
IKR This footage also helped me to explain wave properties to my friends. Like how you can see the amplitude and timbre. Heck this could be set up a quiz question if my physics teacher wants to torture us
Why is it that when you look at an accelerating wheel (like a car's after a light turns green) it starts looking like it is going forward, but then starts looking like it's going backward? I imagine there's no rolling shutter on the human eye, so why does that happen? If anyone knows I'd love to share in your knowledge
i have no clue how we see it like we do. but im pretty sure its caused by accelerating and when your at your steady speed it will start going backwards. i imagine this would happen whenever ever your accelerate and decelerate during your journey. just a mechanics view of watching wheels spin while balancing and servicing cars.
Noah Whiteman I think Michael Stevens on Vsauce mentioned and explain this in one of his videos...can't remember the name neither the explanation...stupid me!
If I had to guess, it is the lag time in our own nerves. We like to think that what we perceive with our senses is instant, but that isn't remotely true. There's also the fact that we constantly take a bunch of still images like an actual camera subconsciously. We blink and our brain "turns off" our sight even when we move it a fraction of a degree. Lastly, we know that the brain loves to take shortcuts, evidenced by visual illusions. So in a way we do have an fps cap on our sight. But I'm not an expert, so take it with a grain of salt.
This shouldn't happen when you LOOK at a wheel, but rather when you RECORD a wheel - if you're talking about seeing this on TV, then yes, this does happen. This is what he mentioned at the very end of the video; the 'wagon wheel effect'. Just Google that. Remember, you don't have to rely on Destin to make you smarter every day. Google is just a click away, and you'll learn way more through doing and researching things yourself. You'll be able to find loads more resources just like Destin's videos.
I love your videos Destin, but this has to be one of the coolest...I know all about shutter speed and persistence of vision but this just brings it on...awesome!
that's why this is one of the best contents in youtube.. omg man. youtube sould treat channels like your different. like monetizing you more or offering more support i don't know. just imagine the awesome things you would do with even more resources to to on those crazy ideas
Destin: Hey its me Destin, get your phone out" Me: Yup, done. Destin: You see the camera right there? Me: Yup, I do. Destin: Now take it out like this. Me: wait, what?
*@SmarterEveryDay* 4:45 Hay! *That is Space-Time!* (right half of the video) Sideways represent space (1D?) Down-ways represents a progression of time. And WE are a multidimensional creature that can see the whole "history" at the same time. (after the green line has "frozen" the time.) And the green line itself is The *Now* "time-point".
Awesome! THAT explains the string theory, man! The strings vibrate so fast, that our sense and measurement instruments perceive these movements as wave!
Vikings488 even better, he put up some python code to achieve the same effect as minutephysics did, without the need for expensive after effects! Python is free, after all :)
This translation is not technically wrong but its connotations are wrong. Priceless implies it is beyond the value of which people can pay, whereas "free" implies it has no value.
2:10 "I happened to have a high speed camera... I also happened to have spent hours heavily watermarking the propellers prior to this very organised film-shoot..."
At 0:40 with the printer, does anyone else think of it as general relativity? The patch is the space ship and scanner's movement your movement inside the ship.
No this video did not earn my subscription!!!! It was your video on binaural audio you did on the Falcon Heavy launch a year ago that got my subscription!! Keep up the awesome work man!!!! Ps: Laminar flow.....
Totally Legit Gaming [TLEG] at the very least, he did a really good job with the propellers. I almost though he actually had them painted on at first XD
Copy / paste from a random website: In very brief, a turbojet is a jet engine, a turboprop is a jet engine with a propeller atached to the front, and a turbofan is a jet engine with a fan attached to the front.
You'd be surprised what 3d software can do. He just tracked the propeller rotating in a program (like Blender), and then added the text. Not saying that it is simple, just easier than ever before...
Do our eyes also have some type of "rolling-shutter" functionality? How do we explain seeing fans spinning clockwise when they are actually spinning counter-clockwise?
@@Xilog Well our brains run on electricity, and have a limited capacity to interpret and process information received from our eyes. So technically speaking we do have a certain "frame rate" just not limited by the photons reaching our eyes but our brains processing the images. A fan's blades will match a certain frequency our brains operate on, and the edge of one rotor blade will be on almost the same place where the edge of another blade was when our brains processed the last time, thus our brain will instantly think it moved "back a little bit" rather than it moved a whole 359 degrees and landed almost on a same place. Thus we think the rotating element simply rotates counter clockwise although we actually know it not to be true.
@@MrDox90 though our ability to interpret "frames" is very dynamic depending on what the movement is and our focus. We can see a single white frame inserted in black for 1/1000 of a second but not a black frame in white at that speed.
We can see a single white frame inserted in black for 1/1000 of a second but not a black frame in white at that speed. it's because humans are better at distinguishing darker colors, that's why that standard 0 to 255 scale is not actually linear but sRGB

Definitely not practical, but very interesting.
Yep... Physics is like lifting weight but for brain. Not practical but will make it stronger.
Yeah exactly what I was thinking, can be a fun way to inspect e.g. the performance of a motor as well... in a weird cumbersome way
Ah yes, I understand that.

I was thinking the same thing. I wonder if the abnormality of the waveform from a pure sin wave correlates to the "cleanliness" of the musical note.
Pub x Stompa no I thought that at first
thats just the wire going back and forth faster than what the cmos can capture
it's a neat thought (had it too :) but no, it's an artifact of sampling, check out "Nyquist rate" for more
I'm pretty sure it's just an artifact of the shutter frequency combined with the strings' vibration frequencies. There's math behind it, but the picture doesn't represent anything meaningful other than looking funky I don't think.

Remember, you don't have to rely on Destin to make you smarter every day. Google is just a click away, and you'll learn way more through doing and researching things yourself. You'll be able to find loads more resources just like Destin's videos.
it's really awesome, especially the simulation. it is convincing.
Your explanations and general level of "interesting" are second to none. From grain bins to this : loved all your films that I've watched.
I love your videos Destin, but this has to be one of the coolest...I know all about shutter speed and persistence of vision but this just brings it on...awesome!
this is beautiful, love it destin! one of my favorite teachers, keep getting smarter everyday!
What a remarkable and engaging video - brilliant explanation of what is occurring. Thank you.
that's why this is one of the best contents in youtube.. omg man. youtube sould treat channels like your different. like monetizing you more or offering more support i don't know. just imagine the awesome things you would do with even more resources to to on those crazy ideas
You earned my subscription bro...spot on...👌
Finally found someone on youtube talking sensible, with practical example.
🙌
i wonder if its possible to create a slinky which can run forever on an escalator. to see the process would be very interesting.
Ninolicious yea put it on loop
Make a slinky gif ;)
Nice explanation & so satisfying 😌
Love the background music!
I wish I could like the video more than once! You are awesome!!!
I Highly recommend you go and watch The Slow Mo Guys video "Inside a Camera at 10,000fps" after you've watched this video
I don't know what to say but I watched that video a while and now i think this video was 2nd part of it with some practical examples.
Editing is fantastic in this. Nice job
Destin: Hey its me Destin, get your phone out"
Me: Yup, done.
Destin: You see the camera right there?
Me: Yup, I do.
Destin: Now take it out like this.
Me: wait, what?
*@SmarterEveryDay*
4:45 Hay! *That is Space-Time!* (right half of the video)
Sideways represent space (1D?)
Down-ways represents a progression of time. And WE are a multidimensional creature that can see the whole "history" at the same time. (after the green line has "frozen" the time.)
And the green line itself is The *Now* "time-point".
The vibration on the guitar strings from the rolling shutter effect is very similar to the waveforms produced by sound waves.
Awesome! THAT explains the string theory, man! The strings vibrate so fast, that our sense and measurement instruments perceive these movements as wave!
Stand up maths did an amazing cheap version that did everything you did with about 10 minutes of effort :)
Vikings488 even better, he put up some python code to achieve the same effect as minutephysics did, without the need for expensive after effects! Python is free, after all :)
“Assuming his time is priceless “ :D
This translation is not technically wrong but its connotations are wrong. Priceless implies it is beyond the value of which people can pay, whereas "free" implies it has no value.
You just appreciate for what it is instead whing that simpsons did it first
Does he have his own plane? Notice the name on the props 2:15
no its edited
2:10 "I happened to have a high speed camera... I also happened to have spent hours heavily watermarking the propellers prior to this very organised film-shoot..."
Excellent video. You can see the guitar string vibrating at their designated frequency. something you cannot see with your eye. remarkable work!
At 0:40 with the printer, does anyone else think of it as general relativity? The patch is the space ship and scanner's movement your movement inside the ship.
uchihasurvival yes, my mind turns there when I'm standing over the work photocopier playing the fool.
No this video did not earn my subscription!!!!
It was your video on binaural audio you did on the Falcon Heavy launch a year ago that got my subscription!! Keep up the awesome work man!!!!
Ps: Laminar flow.....
Not another laminar flow fan... Haha, Iove it too 😁
5:18 how Pringles were made XD
What the I was eating pringles then I saw this comment
@@myearsburn4826 lmao
Can we expand this reply section?
@@myearsburn4826 why not

Brilliant simulation! Best rolling shutter explanation video I've ever seen.
You are Awesome
4:00 now that's what you call a SOUND WAVES
Hands down the best explanation of rolling shutter I have seen. You most certainly earned by subscription.
1:10 similar to the speed of light
This is so stinkin cool
It's a sad thing that you have to watermark your footage these days. Goodamn freebooters!
Totally Legit Gaming [TLEG] at the very least, he did a really good job with the propellers. I almost though he actually had them painted on at first XD
Probably the most informative vid I’ve seen on RUclips. Thanks!
Didn't know you had your own private jet 😉
Ikr
Not really a jet
It actually is a jet engine, but with the propeller attached to the front. Turboprop
So it is a turboprop
Copy / paste from a random website:
In very brief, a turbojet is a jet engine, a turboprop is a jet engine with a propeller atached to the front, and a turbofan is a jet engine with a fan attached to the front.

4:43 Ok, Dustin... bout to become a musician
Who's "Dustin"?
@@HelloKittyFanMan. a friend of Destin, I believe.
@@mark-ish: Haha, Destin and Dustin. I guess that works. One was applying lotion while the other was cleaning the furniture.
Bro I seriously love your enthusiasm. You seem to have kept your child-like wonder and that is wonderful. Stay awesome man!
Wait a second, how does he have his channel name on all these propellers?
After effects.
alex joseph it's his watermark so no one can steal the footage
TheDragonfly256 Please dont misinform, Destin obviously purchased them
You'd be surprised what 3d software can do. He just tracked the propeller rotating in a program (like Blender), and then added the text. Not saying that it is simple, just easier than ever before...
Editing?
Can you read sound from picture of string frequency in 4:42?
3:07 *T A R M A C*
Btw I learned a lot from this video and I understood its message
..beautiful effort guys. You've made such a complicated scientific topic into such an interesting tutorial. Loved it immensely. Thankyou..
I can proudly say that I subscribed before this video went live
As subscribing after this video is pretty obvious. Awesome work man👍
Do our eyes also have some type of "rolling-shutter" functionality? How do we explain seeing fans spinning clockwise when they are actually spinning counter-clockwise?
@@Xilog Well our brains run on electricity, and have a limited capacity to interpret and process information received from our eyes. So technically speaking we do have a certain "frame rate" just not limited by the photons reaching our eyes but our brains processing the images. A fan's blades will match a certain frequency our brains operate on, and the edge of one rotor blade will be on almost the same place where the edge of another blade was when our brains processed the last time, thus our brain will instantly think it moved "back a little bit" rather than it moved a whole 359 degrees and landed almost on a same place. Thus we think the rotating element simply rotates counter clockwise although we actually know it not to be true.
@@MrDox90 though our ability to interpret "frames" is very dynamic depending on what the movement is and our focus.
We can see a single white frame inserted in black for 1/1000 of a second but not a black frame in white at that speed.

it's because humans are better at distinguishing darker colors, that's why that standard 0 to 255 scale is not actually linear but sRGB
3:12 Seems Like the Propellor is Bent for Real.
Wonderful visualization of rolling shutter. True educational material.

Cool! Is there a SmarterEveryDay video for Aliasing/Wagon Wheel effect?
ye look it up
Ok got my subscription. Came from standupmaths
This channel is rapidly becoming my number one RUclips channel. Enjoy every video so far GW
Hes about to DAB!!!(3:19)
