Hey ddoi, I just want to thank you so much for the hours worth of work you create for us. And hope you really earn great things for it in the future! :D
Thanks :) I do have a video on how 3D zoetropes work, and also a video on how the fish animation story is more than 3 seconds long and the animation loop is less than 1 second if you really want to bend your noggin :) I have a question for you though - where did you come from? I haven't figured out youtube tracking yet - but I can see a bunch of mobile traffic, you come from an instagram post?
This is mind-bending. Congrats on doing such a fantastic job with all the pieces. There should be a full TV documentary on this artform. Zoetropes have been around for over 100 years, but nothing remotely as awesome as this. Bravo!
Thanks! you're too kind :) I mean there are a few other zoetropes out there that I think look really good. The Toy Story and Studio Ghibli ones for example. They're obviously large machines with big budgets, and there's other big ones too, although none of them lean into the multiplied-loop technique like me. Maybe I'll get a chance to one-up them one day with a big-budget client ;)
hey thanks! there are more on my channel :) also Fish has been significantly updated since this video, and there's been glimpses of most of the changes, but look out for proper FishV2 coming soon :)
Here a desirable visual artifact associated with the frame rate of the videography. The frame rate is near the Nyquist limit of the rotating platform. Very cool to say the least.
Since they didn't reply I'll take a shot at it.. I'm pretty sure it has to do with the frame rate of the camera (i.e. how many frames per second captured), along with a spinning rpm that nearly matches the frame rate. Similar to how wheels on cars can look like they are nearly motionless or even spinning backwards when filmed if the rpm of the wheel is close to the frame rate of the camera.
For naked eye viewing without the camera: The wooden cross up top has LEDs on the underside that strobe flash in synch with the 20 sectors of animation going past. 20 flashes / rev, 75 rpm = 25 "frames" per second.
It works IRL too with strobes, but strobes do not film well. So for filming I turn the strobes off, set the shutter speed to 1/2000 and adjust the carousel rpm so that the camera sees 24 carousel segments per second. I'll be posting more videos including some with a colleagues camera that minimises the artefacts caused when filming with strobes.
@Adam Hickam - Heh, there's been quite a few changes since then to make them work in 3D - so no - when I was filming above the animation was not visible except on the camera.
try my "how 3D zoetropes work" video 😁 ruclips.net/video/V8nXkthtYPc/видео.html and if you're feeling like stretching your mind a bit more, this one ruclips.net/video/U8ZHJwjGL5s/видео.html
Yes in this video - but also for human eyes when the strobes are on, eg: ruclips.net/video/EBMwX6BTRHA/видео.html in that video the camera is configured to be like human eyes and it's filmed with with the strobes. Off at the beginning, then on, and off again at the end - the main difference against the human eye is that it's better than the camera at handling the colour and light range when the strobes are off or on.
Due to the heat index of your central nervous system in relation to the gravitation of our 4th ozone layer you are seeing a fish eat another fish when really they are starving.
Thank you! - it's actually been improved a lot since 2018, but I haven't had a chance to make a proper video. You can see a short of the new version here though: ruclips.net/user/shortsxYgqy68A-PI
"nuked eyes" 🤣🤣 - not sure if that's a typo or not - since for "naked eyes" strobes create the effect - see here: ruclips.net/video/idemWAE6Jjo/видео.html if it wasn't a typo, then note that the strobes don't nuke the eyes at default frame rate of 28fps, but if you go down below 25fps it can get uncomfortable!
@@alexabadi7458 ahh - I wasn't sure, because if you take the strobe rate down to like 15 strobes per second or lower- and have the brightness up high - then it does Nuke your eyes! I mean it's quite uncomfortable and most people instantly their head turn away and complain ...
Yup :) ruclips.net/video/V8nXkthtYPc/видео.html but it's not just physics, there's an extra mind-twisting "escheresque" ingredient: ruclips.net/video/U8ZHJwjGL5s/видео.html
In real life it uses strobes, normally strobe flashes don't film well and this video was filmed with the strobes off - however I recently upgraded the control software to allow better filming with the strobes on ruclips.net/video/J3o9QBifdrY/видео.html
With the strobes on we normally run it at 100 RPM (generating about 33 strobes per second) but when filming with rolling shutter camera we turn the strobes off and match the carousel speed to the camera frame rate which works out around 72 RPM.

see my reply to your other comment on the "how 3D zoetropes work" - I put a lot of effort into that video, I can't think of a better way to explain how it works. I sell the strobe+frame+motor kits that come with an App for interactive control
can i ask you a question? i singed up for the early deals but i want to know something, does this machine sound very loud or on silent? because there is music in this video we really don't know.
That's a very good question - Our kids react video uses a motor we have since changed for a much quieter one. ruclips.net/video/vnQpPiluqvg/видео.html If you listen to the parts where the kids are just watching intently rather than reacting, you'll hear the noise of the old motor. 4-Mation is now a lot quieter than that.
Well, it's true 3D zoetropes have been around a while, but not like these - the animation is "multiplexed" which means that it's several times longer than you might expect. The loop is only 20 frames long (20 distinct frames/segments on carousel) , but the life-cycle of a fish is over 60 frames long - from fish birth, through to eating fish, through to being eaten. By the way - where did you find us? I've seen an uptick in interest, but can't find out where it's from....
Kevin Holmes through an Instagram explore page suggestion, if you associate with wevolver and that British guy with the toy collection zoetropes show up
I don't understand this. It looks like the animation comes to life after the circular thing slows down instead of when it speeds up. It looks awesome! I just don't understand it. 🤔
try this video ruclips.net/video/V8nXkthtYPc/видео.html ("how a 3d zoetrope works") - and then if you're feeling adventurous try this one ruclips.net/video/U8ZHJwjGL5s/видео.html ("3s animation inside a 1s loop" - about the fish one specifically)
@@n0f8r I think I understand now. Strobe lights makes things appear to be in slow motion. So, the round platform appears to slow down when the strobe light starts, and the strobe light is what makes the animation begin, too. That's what I gathered from watching the other videos, and I've experienced the slow motion effect from strobe lights before. Am I right?
@@scootermom1791 well I won't say you're wrong :) it's a tricky thing to put into words. I will add that the effect relies on "persistence of vision" just like old Cathode Ray Tube TVs (if you remember how boxy and heavy TVs used to be?) and old school film projectors that used reels of film. When light is bright enough it creates a lasting impression on your retina (look at a window - then away from it and close your eyes). Now, because a strobe is so short (1/2 a millisecond) it captures a frozen scene on the carousel - and because it's so bright, that image sticks in your eye - until the next strobe - which is timed to show you the next frozen scene in the sequence (like a flipbook). So, because of "persistence of vision", and because the strobes are so bright - you can't see the blurry bits in between each strobe - and you see only the animation sequence. It does require a minimum speed - if the strobe rate gets slower than 24 strobes (frames) per second most people can see the strobes individually with dark bits in between - and it gets really hard to watch. This is probably why 24 frames per second is the base frame rate for all video today - even though we don't rely on persistence of vision anymore (displays are always on these days, there's no dark parts in between frames anymore).
@@n0f8r Thank you! I do understand the process better, now. I'm one who likes to understand how things work, plus I have a daughter who's into animation. So, I appreciate your taking the time to explain this. And, yes, I remember the big, boxy, heavy old TV sets with cathodes. And projected filmstrips teachers ran in classrooms. And kids arguing over whose turn it was to run the projectors. Those were the days....lol. 🙂
Heyhey, I hope you don't mind, I'm planning to use a part of this for a video in my channel concerning animation. I will be properly crediting and linking it to this video of course!
Yes - when the strobe are on, this video was filmed with strobes Off, but these videos were filmed with the strobes On and the camera configured to see what the human eye sees : ruclips.net/video/idemWAE6Jjo/видео.html ruclips.net/video/h6VtL_donnw/видео.html ruclips.net/video/EBMwX6BTRHA/видео.html
[Traducción de Google] Es un motor de tornillo sin fin de 12 voltios a 100 rpm con codificador que rastrea la rotación. El codificador se utiliza para sincronizar las luces estroboscópicas. Puede encontrar motores muy similares en ebay si busca "motor de tornillo sin fin de 12v 100rpm". La velocidad se controla con el transistor mosfet PWM.
Oui, ruclips.net/video/h6VtL_donnw/видео.html et ruclips.net/video/3I4X7ahv0sI/видео.html Ceux-ci ont été conçus pour une vitesse de rotation de 78 tr/min, avec une taille de boucle de 23 images. Vous pouvez obtenir des disques avec des animations 2D qui tournent à 33 tr/min, mais la boucle est grande, quelque chose comme 54 images, ce qui rend l'animation très petite. À une vitesse inférieure, une boucle plus grande est nécessaire, ce qui signifie une animation plus petite. 78 tr/min est la vitesse de rotation la plus lente possible pour une bonne animation.
@@n0f8r I saw your other videos, it's more complex than I imagined, my record player is 78 rpm, I have to study the strobe lighting system, I'm going to do some tests thx 😊
@@snoufy1 some specifications for you: My strobes are 216 watts in total (although that's RGB which has less visible output than pure white, so pure white equivalent power something like 180watts.) Each strobe flash is 500 µ seconds (half a millisecond) and adjusting the strobe length between 0 and 1 millisecond gives you varying levels of brightness, although at 1 millisecond the animation starts to become blurry - since the animation rotates a noticeable amount in 1ms. The strobes are backed by a bank of capacitors with 1510 µ Farads to make sure the LEDs are supplied with enough instantaneous current At 78rpm with a 23 frame animation loop the strobe rate is 29.9 strobes per second which is comfortable viewing for nearly everyone. A 20 frame loop like frogs or fish at 78rpom is 26 strobes per second - and that is starting to get a bit too slow for some people. At slower rates individual strobe flashes become noticeable as the persistence of vision effect stretches and breaks, and the resulting extreme contrast is hard on the eyes.
I'm wondering. Normally a zoetrope requires a strobe light to see the effect. Our eyesight doesn't flicker. So the fact we see this, I'm assuming is more due to the flickering of the camera filming the rotation. Like when filming the blades of a helicopter, at certain speeds the blades seem to be frozen still. How will we see this with our naked eyes? Also, this was published on Oct 2017. But your page still has a form to be notified of the kickstarter. Will there be a kickstarter?
See the video description - strobes do not film well without a global shutter, so we turn them off for filming. You could also check out our video explaining how 3D zoetropes work, filmed with a hired Sony F55 that does have a global shutter.
Thanks. My question was not so much about how you filmed it, but more about how it will actually work for someone who owns the 3d zoetrope. Nevertheless, you said "we turn them off for filming", which tells me the zoetrope comes with strobes. Which answers my first question. Now the second question I had: when?
I pointed you at the "how zoetropes work" video because in that video the strobes are on. We hired a sony F55 for a weekend to film it. The F55 can film the strobes because it has a global shutter. Kickstarter launches very soon - 14th August.

This is the same as the comics, which will play each frame in rapid succession. However, this can be a good gift.
Do you need a camera to view it like this? Is viewing with naked eye the same?
Since they didn't reply I'll take a shot at it.. I'm pretty sure it has to do with the frame rate of the camera (i.e. how many frames per second captured), along with a spinning rpm that nearly matches the frame rate.

20 flashes / rev, 75 rpm = 25 "frames" per second.

So, I appreciate your taking the time to explain this. And, yes, I remember the big, boxy, heavy old TV sets with cathodes. And projected filmstrips teachers ran in classrooms. And kids arguing over whose turn it was to run the projectors. Those were the days....lol. 🙂
This is amazing!!!
Gorgeous
That's so cool.
"There's always a bigger fish."
there might be some even bigger fish later this year - I have a new large zoetrope machine ....
@@n0f8r You don't get the reference?
Heyhey, I hope you don't mind, I'm planning to use a part of this for a video in my channel concerning animation. I will be properly crediting and linking it to this video of course!
with credit and linking, very happy for you to use - thanks!
@@n0f8r thank you!
@@n0f8r Heyy! I just finished the video! Thank you once again! Here's the link: ruclips.net/video/jT_9nEKHumo/видео.html
Awesome! But, can I see this effect whitout a camera?
Yes - when the strobe are on, this video was filmed with strobes Off, but these videos were filmed with the strobes On and the camera configured to see what the human eye sees : ruclips.net/video/idemWAE6Jjo/видео.html ruclips.net/video/h6VtL_donnw/видео.html ruclips.net/video/EBMwX6BTRHA/видео.html
Bellissimo!@@n0f8r I saw the cost, unfortunately I don't have enough money otherwise it would be a fantastic gift.
Complimenti ancora!!!
it would be great with a nightmare before christmas theme@@n0f8r
That is insane
Ah! The endless circle of life.
This is awesome!
hola quisiera pedir un favor si me puedes brindar información sobre el tipo de motor que utiliza en este proyecto
[Traducción de Google] Es un motor de tornillo sin fin de 12 voltios a 100 rpm con codificador que rastrea la rotación. El codificador se utiliza para sincronizar las luces estroboscópicas. Puede encontrar motores muy similares en ebay si busca "motor de tornillo sin fin de 12v 100rpm". La velocidad se controla con el transistor mosfet PWM.
Est-ce possible de faire un zootrope avec un tourne disque ? La vitesse sera suffisante ?
Oui, ruclips.net/video/h6VtL_donnw/видео.html et ruclips.net/video/3I4X7ahv0sI/видео.html
Ceux-ci ont été conçus pour une vitesse de rotation de 78 tr/min, avec une taille de boucle de 23 images.
Vous pouvez obtenir des disques avec des animations 2D qui tournent à 33 tr/min, mais la boucle est grande, quelque chose comme 54 images, ce qui rend l'animation très petite.
À une vitesse inférieure, une boucle plus grande est nécessaire, ce qui signifie une animation plus petite. 78 tr/min est la vitesse de rotation la plus lente possible pour une bonne animation.
@@n0f8r I saw your other videos, it's more complex than I imagined, my record player is 78 rpm, I have to study the strobe lighting system, I'm going to do some tests thx 😊
@@snoufy1 some specifications for you:
My strobes are 216 watts in total (although that's RGB which has less visible output than pure white, so pure white equivalent power something like 180watts.) Each strobe flash is 500 µ seconds (half a millisecond) and adjusting the strobe length between 0 and 1 millisecond gives you varying levels of brightness, although at 1 millisecond the animation starts to become blurry - since the animation rotates a noticeable amount in 1ms. The strobes are backed by a bank of capacitors with 1510 µ Farads to make sure the LEDs are supplied with enough instantaneous current
At 78rpm with a 23 frame animation loop the strobe rate is 29.9 strobes per second which is comfortable viewing for nearly everyone. A 20 frame loop like frogs or fish at 78rpom is 26 strobes per second - and that is starting to get a bit too slow for some people. At slower rates individual strobe flashes become noticeable as the persistence of vision effect stretches and breaks, and the resulting extreme contrast is hard on the eyes.
I'm wondering. Normally a zoetrope requires a strobe light to see the effect. Our eyesight doesn't flicker.
So the fact we see this, I'm assuming is more due to the flickering of the camera filming the rotation. Like when filming the blades of a helicopter, at certain speeds the blades seem to be frozen still.
How will we see this with our naked eyes?
Also, this was published on Oct 2017. But your page still has a form to be notified of the kickstarter. Will there be a kickstarter?
See the video description - strobes do not film well without a global shutter, so we turn them off for filming. You could also check out our video explaining how 3D zoetropes work, filmed with a hired Sony F55 that does have a global shutter.
Thanks. My question was not so much about how you filmed it, but more about how it will actually work for someone who owns the 3d zoetrope. Nevertheless, you said "we turn them off for filming", which tells me the zoetrope comes with strobes. Which answers my first question.
Now the second question I had: when?
I pointed you at the "how zoetropes work" video because in that video the strobes are on. We hired a sony F55 for a weekend to film it. The F55 can film the strobes because it has a global shutter.
Kickstarter launches very soon - 14th August. Sign up on the website for reminder email 4-mation.co.uk - or follow our facebook facebook.com/4dashmation
The very limited Early Bird rewards will ship in time for Christmas and have discounts of 20% or more.
Thanks. signed up and also joined the forum :)
Вот чудеса! Интересно то, что когда это волшебство прекращается (остановка круга), то мозг не может поймать этот момент.
Это другое, но лучше лично со вспышками. Это видео снято без вспышек, поэтому переход странный - но со вспышками переход мгновенный - посмотрите это видео, камера настроена на приближение к человеческому зрению: ruclips.net/video/idemWAE6Jjo/видео.html (это не так хорошо, но примерно так это выглядит)
@@n0f8r ааа.... Вон оно что .... Как необычно меняется восприятие 😳
Wow so cool
Is this effect visible to open eyes
see the description - strobes create the effect IRL. Also see our other video on how 3D zoetropes work.
Kevin Holmes thank you Kevin
