Gabriel Guedes Balogo Well actually I have never realised that his channel grew so fast. It was like 100K last year and it tripled. I'm sure Destin may have already watched this video.
OK I thought along "use Lego motor plus rubber wheel to rotate cardboard at more constant rate"... seems simpler improvement. Most slowly-discharging windup things would also work.
Excellent video Matt. I love your "teach a man to fish..." style when it comes to educational material. You try to make things accessible to everyone, and I appreciate the effort you put forth.
You could of course make some out of paper and some tape for about 0.003 cents. At least he has a drill for free, from somewhere, somehow... Makes you wonder... :p
I don't care that this is the second video on rolling shutter i've watched in the last week, at 3:10 i'm literally LOLing at the simplicity of this method. Great work Matt!
lol, yes. Also a lot of things is possible with hust a few lines of code, but when you are not familiar with coding that much it may take few hours or days to research how those lines should look like.
NetAndyCz You always write these few lines of code in few seconds. And then you spend days adding clustering, remote control, GUI, a hidden game, capability of piloting Star Destroyer. Just because a utility with just one function is boring.
Matt, this is the most perfect explanation of rolling shutter i have ever seen, my 12 year old grandson had no trouble understanding the phenomenon after watching it happen in REAL TIME. It truly is a gift to be able to explain complicated things simply, I wish I had that.
I love that all the great science folk on youtube work together and/or mention each other's work. You all rock and I'm glad I'm subscribed to all of you. :)
I was about to type: "So many cool things you can do in Patreon!". Your not so subliminal subliminal message really worked Matt, good job! I meant Python by the way.
This had so many genuinely funny moments, I can't be more happy to watch your videos whenever they come online. Here's to hoping you come to Ottawa sometime. *Fingers Crossed*
I've come up with a simple Python Graphical User Interface implementation of the code in question (with some additions): github.com/alexd3rsan/rollingshutterpy It's written in Python 3.x and has been successfully tested under Windows 10 and Arch Linux. You'll still need Pillow (PIL) in order for it to run (just like the original code does). It additionally checks for 'missing areas' caused by lacking frame count, or too low shutter speed. It's still a rapid prototype though, so be aware of that! I'm happy to try to fix some potential errors though. :) The most important thing missing IMHO, is the lack of the infamous 'parker square' symbol as application icon. But there is always room for improvements like that (and any other critical error, ofc). Hope it helps! Have a nice day! :D
I'm surprised you haven't talked about the Quadratrix of Hippias! It's a curve generated by rolling shutter which trisects angles and squares circles :)
Marcos Vinícius Petri Just like a "rogue" mathematician turned programmer to generalize an idea to the point of absurd comedy! My favorite bit, by far. Especially because he ignored it, as if it were no big deal.
This scientific community is golden, big plus for Stand-up Maths, Smarter Everyday, Practical Engineering, and all of you guys (there too many good scientific content youtube channels to list all of them, ps. love Diana #PhysicsGirl) for doing whatever you're doing, but also for cooperating or competing with each other to make us, your audition, smiled and knowledge full all the way down. Cheers
Epic budget build for the win by showing us all how time and its measurements are relevant only to the observers time frame that they are familiar with.
Yeah he was taking the piss at Destin for going above and beyond for his video. with the branding of his page everywhere as a watermark to stop freebooting pages from reusing it. Destin thought it was great fun. He's a swell fellow. He can take the piss like no other.
I just stumbled upon your presentation and I would certainly say that your pure British humour was worth gold to make the other person curious enough to understand that nowadays we really live in a fool's paradise in the endless vast digital ocean. The only rescue boats are the ones you made for others! A fan and an admirer from Pakistan!
I came to this video expecting to hate it thinking it was a clickbait / rip-off of smartereveryday's video, but well done, great video adding valuable information and further insight! I usually never comment on videos but you've gained a new subscriber ;)
The collegiality of the Science TH-cam community is the best thing since the British Royal Society was founded. Seriously, you all make me proud to be a curious human being.
I had not looked up the channel for a couple months (I had forgot about it, how could I D: ), and I come back and see this video It's pure gold!!! :D Laughed during most of it :D Good job Matt! :)
I found Destin’s video annoying to watch. Then again, I'm not a fan of his channel, like the content, don't much like his style. (Still subscribed as the content is normally good.) Yours has a better scene of humor and is much less pretentious. So you get the thumbs up instead. :)
I saw Destin's video first and I really enjoyed it, but I must admit - I did loved how simply you were able to recreate his effects (and your explenations were quite funny too). The only problem I had was how simple you made it sound to write that Python code. I don't think a lot of people could have just done that. It would be cool of you to make the last method with the scanner more smooth and show that! Granted you own a scanner or have access to one, I think that most of us could then recreate the effect our selves. Anyway, great video!
This is the difference between math (and science) and engineering. Engineering just wants something to work but math needs the elegance and simplicity to make the core idea obvious! Great video!
For propellers you can use a filter to remove them from video. Lots of aviation GoPro kits come with a filter to help remove the prop distortion. Not exactly sure how they work, but it’s something with the filter lowering the light level which slows down the shutter I believe.
I see the error of my ways. Please forgive me. The branding bit was hilarious... a highlight for me personally. Also, big fan. Been following you on twitter for years.

Bam. A place for corrections pre laid out despite there being none, and an encouragement to viewers to notify him of any problems.
More a sign of humility. And experience.
Franz Luggin lots of experience with corrections. Almost like a Parker square needed some corrections :p
That is just a standard maths thing :)
I'd say a standard science thing.

And you already own a drill.
Fun fact, this is Linux's official motto.
actually in recent years microsoft mastered that to perfection
Would you buy a car if you couldn't open the hood? Ironically though, most cars these days are probably running proprietary software.
If Stallman made a car, would it constantly stall?
Yay for doing science without all the fancy equipment!
Can do it for £0 if you find an image of a propellor and spin it with python code
Wouldn't it be nice if someone programmed this and shared it?
Just steal the electricity from the neighborhood
Zutaca Libraries.
Aexerus did you watch the whole vid ?
@@valeforedark you don't understand what he meant. No physical objects, just an image of a propeller put in the program and coded to spin.
Gotta admit, I prefer the DIY approach and humor here over the SED video.
Amazing! The budget version, not quite perfect but its a Parker square of a technique. :)
jonlottgaming and the return of the fidget spinner... remember that parker gyroscopic procession from last time
Speaking of which, you could totally substitute a fidget spinner for a propeller.
Just set, spin, scan, DONE.
You know, at least he gave it a go!

"Assuming my time is worthless."
I can relate.
ITV: Matt roasts destin over their different budgets for videos.
The most elegant way would be to get the pilot to rev the propeller down to 6 rpm.
... in the name of science.
That will be an easy way to DEATH!
Elegant way to die as well.

0:49 "The bottom is the future."
Now here's something I can agree with.
@palmomki why not both? :D
But he misspoke. The bottom is not the future. It's just the more recent past.
Shhhhh.. It the future
As Obi-Wan might say: It _was_ the future, from a certain point of view.
Your icon says it all dude.
So that's how AT&T's logo was created
I think you overpaid for that propeller.
He's a Parker square of an employer.

Be smarter, not harder? Idk man, hardness is kinda important, too.

Ah, yes, the Linux paradigm: anything is possible if you can code and your time is free!
lol, yes.
Also a lot of things is possible with hust a few lines of code, but when you are not familiar with coding that much it may take few hours or days to research how those lines should look like.

Damn he started the tiktok trend before tiktok even existed
It started in September 2016
Super cool! You could also simulate the prop slowing down or filming at a higher framerate by having your code pull 2 lines from each frame.
Can you also make a video calculating the graph you get ? Also Patreon changed their logo.

For propellers you can use a filter to remove them from video. Lots of aviation GoPro kits come with a filter to help remove the prop distortion. Not exactly sure how they work, but it’s something with the filter lowering the light level which slows down the shutter I believe.
