- Ever wondered how they film a tank shell in flight for over 100m meters like it was travelling at walking speed or the instant of a nuclear explosion.
In this video, I look at the super high-speed cameras that can run at millions of frames per second that were made well before the modern electronic ones of today as well have the amazing flight follower systems and the fastest real-time tracker in the world.

4:26 Pushing the most expensive and sensitive high speed camera with one hand, smoking a cigarette with the other while wearing a formal suit. The 1950s were something else.
Yeah relaxed
And they look stylish in 90° temperatur
The more I see the 50’s, the more I know I was born in the wrong time :-P
If you were black, it was just another bad decade as you awaited reparations. Or so they say. For those of you who ask why I have to crap on this with that observation, I'd submit to you it happens every day more and more and most of you say and do nothing and probably vote democrat.
@@Chris971. Your lack of sentence structure disturbs me.
Absolutely fascinating! I've watched tank and missile flights in the past without even thinking about what went into being able to get the shot. Pure genius!

If you had to look at all 25 million frames that high speed camera takes in one second and you looked at every frame for just one second it would take you 289 days to complete that task.
Or 4.82 days if viewed at 60FPS

LOL
“Solids and liquids are incompressible”
Shockwave: Hold my beer.
" . . . it would take you 289 days to complete that task."
Hell, I can't even seem to do a load of laundry or clean the house in 289 days. Forget about strolling through 25 million frames of footage.
It would be a bit boring though, to say the least. I imagine It would take several days to see any change in the image.
00:40 the “projectile” shows a full armour piercing round (APDSFS) WITH the propellant charge (the bulky part at the rear). In reality only the pointy black part would fly towards the target and deliver the kinetic energy. The sabots would discard a few hundred meters from the muzzle.
Fascinating video! It's surprising to me to not only track a shell like that, but keep it all in focus too since HS cameras normally have to use very large apertures to get enough light in which makes for a very shallow depth of field.
TAOFLEDERMAUS since you know ahead of time where the bullet will travel, that should not be a problem.
Yes just a matter of the lens refocusing at a predetermined rate... All you need to know to keep it in focus is where it starts, where it ends, and how fast it's going to get there. The lenses don't have to move nearly as much (in terms of mass/inertia/momentum) and can keep up much easier than an entire camera assembly
I'm wondering about the triggering of them too. I guess light beams or other triggers can be used, as long as you can synchronise them, but if you only had the firing button of a gun to trigger, it would need careful delay adjustment before the camera starts its tracking run.
How is it impossible to see anything especially with film??? I mean exposure time is so short I can't imagine how high of an ISO film it must have been to see anything. I mean all you should see is grain right?
When shooting explosions, a mirror is often used to protect the camera from explosion and shrapnel. The camera is located behind a reliable barrier and watches the scene through a mirror, when an explosion occurs, the mirror is often destroyed, and the camera does not receive any damage. It's a simple way, but judging by many videos, many bloggers don't know about it and as a result their cameras (often an expensive smartphone) get damaged or completely destroyed.
Wow, Lord Varys sure does know everything

Im glad you did a video on This, I have used a BOLT but the the Tracker FFS is a simple genius idea, first time i saw one i was very intrigued. love you man !
You are king on youtube love your show
Loaded 22 that's very nice of you, thanks.
Why don't you use these types of cameras on your show instead of phantoms? 1mil frames per sec. Isn't faster better ?
Curious Droid deep thanks, I literally watch every single one of your videos, every one gives me that feeling i had as a child (7yrs old) and started studying aircraft, space and Aeronautical Engineering. My eyes and brain are "locked on" , you cover all of the subjects that I wish I had time myself to research and read about myself.
Warped Perception I just realized I’ve watched your videos before. I gave you subscribe.
As always you’re content is well thought out, clearly presented, and interesting. To add the cherry to this information sundae, your shirt game is epic. Well done.
Having worked in precision optics, I can tell you the tolerance of the surface of those mirrors is just as impressive.
The reconnaissance aircraft cameras work the same way.
I remember on early mirror tracking setup where the mirror was made of polished beryllium, maybe in the late 80's.
How is it impossible to see anything especially with film??? I mean exposure time is so short I can't imagine how high of an ISO film it must have been to see anything. I mean all you should see is grain right?
Always a great quality vid sir! Ended up binge-watching and rewatching your channel.
This filiming technique had perplexed me for years!
Jake Fuller , i believe the mirror trick was borrowed from Hollywood. They used to use a similar technique for filming a train coming head on at the camera, like in the old silent films about a damsel tied to the track,lol. place the mirror on the train track and the camera off to the side and it looks just like its gonna run you over
It didn't even cross my mind that, yeah, a projectile definitely flies faster than any conventional camera could pan. Amazing to learn about these mirror cameras.
was surprised in artillery school that you can watch shells coming out of the gun and going down range
First, I wouldn't say any of those are conventional cameras. Second, the use of the mirror to track the object allowing the camera to remain stationary simply grasps the physical laws of inertia and mass. The use of the mirror simply minimizes the mass involved in the 'panning' meaning that while it is possible that a camera could 'pan' the projectile, it would be comparatively stupid to do so given the costs of constructing a contraption capable of doing so.
I trained as an Aerospace Engineer. How did I now know about the "mirrors to follow fast-moving objects" before now?
Thank you for this wonderful video! Enlightened someone who thought he knew about this topic already!
"Reader Service Cards" in the back of industry trade pubs?
Ask me how I know ...
This is one of the coolest and most incredible video I’ve seen in a looooong time here on YT! Really impressive I’m into video and crazy images and never heard any of this, thanks for the awesome information and footage!
0:22 Who fires 155mm artillery rounds with the lifting plug still in the nose?
That's what I was just wondering
Noobs, that's who.
Yeah, no personal knowledge but it seemed really odd. Doesn't a detonator of some sort screw into that hole?
@@denniswalsh8476 I was artillery in the Army. Yes. A fuse screws into the nose.
Maybe it was part of a test to determine how it acted if that was the case? Be useful to know how a round might look to an observer or a targeting computer if some derp doesn't put a fuse in. If you didn't know it was aerodynamically different you might "correct" for a bad round and screw up your next good one.
Finally someone answered this question thank you!

25 Million FPS, my god.
That's normal, I play games at 25M FPS
What has science done?!
You haven't seen MIT's 1 trillion FPS camera. It can take the photo of moving light itself.
MIT's camera cant do moving objects
MIT's camera shoots stills at a resolution of 1x300 or something. They den shoot hundreds of those to compose each frame in the height direction, and then shoot multiple frames by running the light again and again.
That shot at 0:19 was awesome! You can see the distortion the projectile causes in the air, that's so cool. Very interesting video, good work.
I bought a camera in 2008 which could record in 1200 fps. So fun! I'm still waiting for something better to come out on the consumer market. Mobile phones are getting pretty close with their 960 fps in high resolution, but they are always very limited in recording time.
Great video!
what camera is that?
Watching this video made me realize how incredibly stupid I am compared to the minds that created these inventions.
Same here
Never doubt yourself.
But same.
White people are amazing
Inventor of the mirror was AMAZING genius !!!
And never realize HOW BIG the invention was! XD
At some point they were stupid before they got to those inventions, so we're all techically on an even playing field, but just a matter of our choices brotha.
When I think Curious Droid can’t educate me anymore I’m proven wrong.
Always something to learn
I was about to write something similar but perhaps more humble. I enjoy feeling uneducated in this company.
Gettin' learnt.
Even his shirt talks about mirrors and projectile
And to think I'm happy with my Panasonic DVX200 at 24 FPS... Would absolutely love a Phantom, but it costs about the same as my house -- don't think the wife would be happy to come home to that surprise. "Hey honey, now we can record the cats at 160,000 FPS!" -- Yeah, she'd be pissed. :)
pmgodfrey hmmm not so sure...maybe you should try at least once...she loves you anyway! :P
I'll let you know what happens if I buy one. Got any room at your place? I'll bring the Phantom. :)
You could film her reaction at 160kfps and share...
Haha maybe you should buy two, just in case she takes one away from you.
That's actually a good idea...lol Double the pleasure, double the divorce!
I just blink my eyes real fast and you get the same effect.
25M blinks per second
@@MAGNETO-i1i hes pretty good
@@cursedcliff7562 she
Forget it
Who else tried to blink as fast as they could when They read that
The way we use to capture high speed pictures of aircraft was to have a few hundred cameras lined up next to the flight path, shows some very interesting images of aircraft skins and control control surfaces.
when i watch those videos i always think:"damn there are some smart ass humans out there"
White people. 👌👌
And then you look around you at the shops and see plenty of examples of the complete opposite.
Aliens did it

That shirt is definitely created with some kind of mirrors!
USWaterRockets suspect no mirrors at all were involved...
it is very loud, though... i had to turn the sound off or risk hurting my eyes..
Baaa!
jimmy playinghardball2 Can you remember all the drugs you have done?

The "tank round" at the 0:22 mark is actually an artillery shell...and an unfused one at that. The eyebolt lifting ring is still attached. Probably wouldn't detonate on impact.
Curious Droid And a full bore proyectile wouldn't travel at 1500 m/s, only subcalibrated ones.
And another very important thing, cartridges don't fly still attached to the projectile like the APFSDS at 0:39 haha
Anyway good videos, even when a bit sloppy :)
With or without an eyebolt on the front, it hits you, you will know it.
actually, you won't :P
Just plane super WOW. Fantastic. I have always been fascinated by high speed videos. Thanks a lot for posting this.

The red leg artillery shells we sent down range in viet nam were cluster munnitions with timed fuse , usually set 20 28 sec. to explode over a target. the other were W-P , high explosive, illumitation , to bring light on a target. 155MM / 175MM/ 8" and toy 105 cannon 4th inf div. LZ. Blackhawk. LZ oasis. LZ Mederith, Lz. Schular/ LZ X-Ray. 10th armored cavlery
This is almost beyond belief. Projecting an image on a bouncing ball? This is AMAZING!
As a professional photographer I find this extremely interesting.
Pretty sure I'll be sticking to stills though. I can only imagine the cost of one of those cameras.
Thanks for taking the time to share. High Speed photography has always interested me and now I know how it's done
That's some mindblowing numbers!
Is there some sort of super fast camera that can record how fast my wages go after i've been paid?
I'm buggered if i know where it goes...but it must be nearly instant!
One test you can try is: how big is your right arm compared to your left. If there's a > 10% deviation, this may suggest that a portion of your wages are going towards internet porn. If you have a burning sensation between your legs and have difficulty walking in the morning then porn is to be suspected with a high degree of confidence. If you feel dehydrated in the morning and have headaches and memory loss, this would suggest that a portion of your wages have been spent on alcohol. For a more accurate diagnosis please send all your wages to wheredidmywagesgo@thepornbar.com
strange lee *Its very simple really... just ask your wife.😉*
I hear ya strange lee. And no, not porn. Possibly alcohol, knives and fishing shit for me. But not porn because I have a healthy imagination...
Casey....No way! It can't be my lovely wife (who is standing behind me).

Great video its amazing what is being done with high speed cameras today. For thirty five years I worked at White Sands Missile Range and we worked with mostly Redlake cameras Hycams and Locams. The mirrored shutter of the Hycam always fascinated me.
There was a piece of film in the late 1960s early 1970s called the world’s fastest pan. High speed cameras had rotating prisms in the 1950s. Great stuff.
How is it impossible to see anything especially with film??? I mean exposure time is so short I can't imagine how high of an ISO film it must have been to see anything. I mean all you should see is grain right?
A pinhole camera is the only kind of camera I could make.
How much for an aircraft carrier Mister Asselineau ?

You want me to do some Macron ? Think Spring my friends !
That projection on the pingpong ball is awesome, ill take 2 😃
I remember when that rail gun video first came out on YT and all the comments and speculation as to how it could have been filmed. Thank you for solving that little mystery.

25Million frames still wont be enough to see me last in bed
your hand would be just a blur.
A frame exposure of every 20 minutes would allow me to appear like any normal human getting out of bed for any sort of work 🐌 PS: A snail is mugged by a gang of slugs, and while being interviewed by the mollusc police, he was asked what happened. His reply was “I don’t really know. It all happened so fast!“
@@Johnny-sj9sj top tier joke
I liked the way the camera showed the pressure wave off the nose of the tank shell at the beginning of it’s flight. I believe it to be the supersonic shockwave. Very cool, thank you!
TH-cam must allow only people like the curious droid to hold channels , usefull, interesting content and ASMR voice, thanks for your work
A GOOD INFORMATIVE AND ENTERTAINING VIDEO, Thanks.
Amazing. How about a video on the fastest modern cameras?
This basically covers it - if you're thinking about conventional cameras that shoot to RAM, look at the iX Cameras i726. That's the fastest camera in the world by both throughput and specs.
You've seen it perhaps, if not, Paul also did a great video on "5 Most Amazing Cameras in the World" th-cam.com/video/cm0KJC3b3UQ/w-d-xo.html
I saw a video where scientists filmed a photon. That's the speed of light the fastest moving visible thing in the known universe i believe they had multiple computer controlled cameras.
The worlds fastest camera at this time is can the STAMP, “sequentially timed all-optical mapping photography” it can shot a a frame rate of believe it or not, 4.4 Trillion frames per sec, google it and watch the youtube videos on it and tell me you are not impressed with a camera that can slow the individual light pulses of a laser beam ( though a coke bottle lying on its side.

Alright,
Ultra High Speed Camera: Check
Tank Shell and Barrel:
Nuclear Bomb:
I remember back in the 60's in high school, in our science class they talked about what they pronounced "Fast-AX" cameras. They did not use a mechanical shutter but a revolving mirror to catch the action.
High Speed/Slow Motion/Time Lapse cameras/photography are truly amazing inventions, seeing realities never seen.
Theres like no doubt in my blown away eyes and mind that what we are actually seeing here is the temporary creation of another universe of stars and galaxies, cosmic dust clouds, merging bubble verses and super nova, so freeze frame, enlarge, zoom inwards and take a provocative look > 3:53 > 4:06
Who came from The Slow Mo guys and said "Mirrors"? 0:34
Njowo opo rupamu wike
Nope
Yeah . It is how TH-cam recommendation engine works
We need to know about your shirt though! :p
Its easy. Tank "shells" dont fly very fast. The projectile might, but the shell rarely does.
Really appreciate you adding in the info about the part about the legs of the tower being sorta visible in the atom bomb explosion. I was genuinely curious about that and getting closure was awesome.
Those pictures of those shells in flight are remarkable!!!!!
WHAT ARE YOU DOING DOWN HERE?!? It's dangerous... this is where they live, you know?
They want attention, likes, and sometimes, even your money...
Quickly now, get back to the video, i'll hold them back
Hype Ninja
Not all heroes wear capes.
Not the hero we deserve but the hero we need.
Thanks Paul, now that's something that I have wondered about for a while.
it's hard to image how the camera reach the velocity,25million fps per second
My impression is that it is a unit of measurement to a common frame of reference so that we can understand it. There is no "film" but an electronically saved image on a CCD.
The double mirror idea is brilliant !
Yes war robats can use that very well
This isn’t the stuff I’m usually interested in on this channel but I really liked this video.
if helium is the answer to reduce the drag in the camera, why couldn't a vacuum work better?
Curious Droid, wow! thanks for taking the time to reply😊
I guess two reasons:
1. Thermodynamics: Vacuum is not capable ofconvecting heat .. things would get really hot at these speeds;
2. Operation safety Vacuum pulls in (dirty) air in case of an unnoticed leak, Helium would just vent of that leak and would easyly be replenished from the helium tank
Another possibly is helium would still be a better match for the index of refraction for delicate optics.
they are using sealed helium instead of atmospheric air in newest high quality hard drives. It's all they need to reduce the friction they need.
Groxu, I thought about that, too. I guess it would be doable, but at least end up being impractical / very heavy.
MIT Labs built a camera that does 1 trillion FPS.
The latest Frame Rates are 1 Trillion X10th power. A light particle actually seeing itself. Well, sort of?...As for the Electron, It is still not known if it is a Particle, Wave, or Photon..
Do you know UPR ?

We did something like this back in 1978. Primitive but state of the art back then. Modern cameras and digital has really improved.
As a baseball fan… I deeply appreciate you having an idea of the size of a baseball and using that as the comparison.
what is being shown is not the nuk 1st explosion within but the after explosion which is conciderably slower then the actual initional / first

Actually its the third. The ignition for the ignition was faster hur dur

Great shirt :)
How do you get a proper exposure with such short "shutter time"?
By aiming the camera at something very very bright, like a nuclear blast :P
Holy cow absolutely astonishing and unbelievable. Just when you thought you've seen it all. How in the hell you get any thumbs-down is beyond me but thank you so much for uploading and taking the time to explain in the video.
In the Royal Artillery we had EVA electronic velocity analyser . We had them with the pack howitzer then the 105 light gun. periodically it would turn up on an exercise to film the shells with a view of keeping an eye on the effectiveness of the barrels after so many shells fired over the year.
That shirt! !!
When it's about war, mankind made extreme efforts and progress and spent huge amounts of money to destroy other humans better and faster. We are a bunch of psychopaths.
We ?
All that's left is for word to get around how good we taste.
And unthinkable things never happened in the past?
Simple rule of probability: Any event of non-zero probablilty will happen eventually if you just wait long enough.
Mutually assured destruction is not a threat. It is a prediction.
Waging war is wrong but losing a war worse...
we also made some big technological advances during war such as improved flight.

Brilliant posting. I've seen of few of your videos and I've enjoy them and learned from them. Thank you!
Great video! Never actually give it much thought how they could get so much FPS before the digital age. I actually thought it was a present day computer morph type of thing. As in you get 2 images and morph the two and get say 10 in between (or what ever number you want). Amazing stuff, you learn something new everyday!

wow, incredible idea
This just popped into my feed and got my attention because the title reads “tank” shell but the still photo is an artillery shell. Not the point of the video but there is a difference. If you know that difference than you know what this means too, KOB!
I'm glad you did a video on nothing to do with what the description said. As far as making it seem you'd show a video of the title.
The footage at 0:22 is so beautiful. What fantastic precision and resolution. I got tingly just watching it. Another shoutout to Doc Eggerton, my photo imaging hero, who was an immortal wizard of this sort of thing decades ago.
Fantastic video very informative. You shirts are always interesting as well. keep up the good work.
Wild. That last part makes the eye/face/subject tracking in modern consumer DSLRs and mirrorless cameras seem way less impressive.
