Really liking those integrated watermarks

@ThatDonovanKid 7 лет назад

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.

@Lezenda 7 лет назад

definitely necessary thing, and made in smart way)

@mwbgaming28 7 лет назад

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

@mwbgaming28 7 лет назад

@kurtu5 7 лет назад

As easy as it is to put them there, its easy enough to take them away.

@LukasDolezal 7 лет назад

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.

@kumowarihtrisno 7 лет назад

Wow. Thats amazing

@HoratioAccel 6 лет назад

@zwep 6 лет назад

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

@zwep 6 лет назад

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.

@vnkyvnkt 7 лет назад

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

@Darkerfoxtech 7 лет назад

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.

@johnsagebiel7261 3 года назад

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.

@3DMEMES 7 лет назад

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.

@bradymcbride284 7 лет назад

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).

@davecrupel2817 7 лет назад

Ive been familiar with that trick of light for decades. Didnt think anyone else was interested in it though. :)

@865MusicByHavoc 7 лет назад

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!

@hackerofawesomeness 7 лет назад

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.

@Majerkellous 7 лет назад

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).

@Majerkellous 7 лет назад

Byte11 that's a long explanation to say that I don't think (I could be wrong) your eye has an fps :)

@t4iga121 7 лет назад

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.

@865MusicByHavoc 7 лет назад

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.

@SIMKINETICS 7 лет назад

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!

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

@InMyZen 7 лет назад

always wondered about this

@ImTheKwaaD 7 лет назад

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!

@ketsuekikumori9145 7 лет назад

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.

@OhSoUnicornly 7 лет назад

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.

+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 🤔)

@johnuferbach9166 7 лет назад

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^^

@rydaddy2867 7 лет назад

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.

@HappySlappyFace 7 лет назад

Pub x Stompa no I thought that at first thats just the wire going back and forth faster than what the cmos can capture

@noliver7913 7 лет назад

it's a neat thought (had it too :) but no, it's an artifact of sampling, check out "Nyquist rate" for more

@wheffle1331 7 лет назад

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.

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.

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?

@MrDox90 5 лет назад

@@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.

@Jaker788 5 лет назад

@@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.

@groszak1 5 лет назад

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

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.
