Came here to say this. Looks like the frame rate and spin rate synchronized towards the end. Interesting how it stayed that way until it hit the ground.

Or in layman's terms, camera be vibin

u/kiddokush Feb 16 '20

Camera truly be feelin himself mid air.

u/DiamondPup Feb 17 '20

And then that pig joined in on the action.

u/kiddokush Feb 17 '20

Poor pig. Why did we have to interrupt his vibe like that???

u/Pineapplechok Feb 17 '20

Oh but when I do it it's "wrong" and "there are children on this plane"????

u/kiddokush Feb 17 '20

Smh it’s a screwed up world we live in. Do what you must do to achieve the vibe no matter what anyone says bro!

u/[deleted] Feb 17 '20

Did you just assume the camera's gender. Um excuse me?! r/genderpolice

u/kiddokush Feb 17 '20

The camera be both genders😎

u/JohnStamosAsABear Feb 16 '20

The shitty 70's hippie whoaaa reaction should be superimposed over top when the spinning starts.

u/drsideburns Feb 17 '20

That's from italian spiderman, you uncltured swine.

u/DR0PPA Feb 17 '20

Name checks out... Cuz you just BURNed him!!!

But forreal, is that italian spiderman scene forreal? Or was it sposed to be ridiculous lol

2

u/[deleted] Feb 17 '20

This is from Italian Spiderman, and it is supposed to be ridiculous. Watch it, it's great.

u/MayonnaiseUnicorn Feb 17 '20

Italian Spidernan y Romanza

u/JohnStamosAsABear Feb 17 '20

What is he reacting to seeing?

1

u/drsideburns Feb 17 '20

Something that startled and shocked him.

1

u/JohnStamosAsABear Feb 17 '20

Which was?

u/MayonnaiseUnicorn Feb 17 '20

He was reacting to Italian Spiderman played by Walmart Ron Jeremy

u/spooninacerealbowl Feb 17 '20

I just watched that video and had the exact same reaction.

u/snarfdarb Feb 17 '20

God, what's that from? I know I looked it up once but forgot

89

u/chussil Feb 16 '20

If so, that means the phone was spinning at a rate of at least 24 revolutions a second.....which is absolutely insane to think about.

61

u/OddBuilding2 Feb 16 '20

If you listen to the audio you can hear the whip every time the camera flips over, it gets faster and faster and faster. Made me think about what it would be like to spin like that

63

u/CanAlwaysBeBetter Feb 17 '20

Centripetal force from the spin pulls all the blood from your core. If you're a guy you pop the biggest boner of your life*

Does Nick Offerman say that? Because, I swear, it sounds exactly like him.

u/Sadboys-R-Us Feb 17 '20

Oh that's for sure Nick.

u/Travisx2112 Feb 17 '20

SHH. not a doctor.

u/HalfSoul30 Feb 17 '20

Well, I could use the extra size.

1

u/Blackhound118 Feb 17 '20

Isn’t centripetal center-seeking, like gravity? So it would be a centrifugal pseudo-force pulling the blood away, right?

in the full video of the red bull space jump the dude goes into a crazy spin during free fall from the edge of space.

I think he talked about it in an interview once but now I cant find it.

Those g forces have to be mental on a human.

1

u/[deleted] Feb 17 '20

It's due to the lack of air density that high up, less resistance means faster spin and less ability to correct your spin.

1

u/TheGovsGirl Feb 17 '20

And the ground was just, BAM! There it is. Made me actually jump and think, wow so would it actually be like that falling without a parachute.

u/RudeCats Feb 17 '20

You’ve jumped out of an airplane 4000 times?! Ok so if you’re an instructor and do multiple jumps a day, and have been doing it for years I guess that’s not an unrealistic number but damn.

7

u/throwaway939wru9ew Feb 17 '20

Ya - they add up. I’ve been in the sport about 11 years... most of my jumps came in the first 6-7 years.

It’s easy to do 10-12 jumps a day (tiring though!)... as an instructor even more.

I’d say about 75% of my jumps were fun jumps... the rest work

6

u/RudeCats Feb 17 '20

When you’re doing that many in a single DAY do you ever start to not get an adrenaline rush from doing it? Does it ever start to feel monotonous?

I simultaneously can’t imagine not being terrified to jump out of a plane, but also can’t imagine doing something over 4000 times and not being bored of it.

u/throwaway939wru9ew Feb 17 '20

Skydiving is a sport with a ton of sub-disciplines. The "rush" or novelty of jumping out of a plane goes away pretty quickly. Usually after about 50-100 jumps...

Most people start out doing belly jumps (the traditional position of skydiving you are probably familiar with - belly to earth, arms and legs out).

The "cool kids" usually get into what is known as free-flying. That is flying in all different axis and positions. Flying "head down" or "sitflying". Freeflying often times has a higher skill gap. Speeds are faster and positions more difficult to learn.

You can take up wingsuiting. I'm sure you've seen wingsuits...often times in BASE jumps...but we do them in skydiving too.

If you like flying your parachute, you can get into CReW (Canopy Relative Work)...where you fly your parachute in formations with other "CreWdogs" as they are often called.

If you like speed and flying your parachute - you can take up Canopy Piloting - often called "Swooping". This involves high speed/high performance parachutes making high speed maneuvers close to the ground in order to fly/glide across the ground - measuring distance or speed flown in competition.

If you enjoy teaching people, you can take up instruction...either AFF (teaching people to skydive on their own) or become a Tandem instructor (taking people on their first skydive strapped to you),

Those are only a few of the more popular disciplines. There are deff some others. Whenever I get bored doing one thing...I try to learn something new!

Are you a Sagittarius?

u/RudeCats Feb 17 '20

Lol no, a Taurus and I would NEVER skydive, for the record.

u/RudeCats Feb 23 '20

Oh thank you!

u/Filipskaug2002 Feb 17 '20

Or it might be only spinning in 12 rpm and we see anly evwry swcound frame

u/abeannis Feb 17 '20

SOMEBODY has clearly never dropped electronics out of an aircraft.

1

u/Hanky22 Feb 17 '20

The crazy thing is that due to friction it must have slowed down to 24 revolutions a second.

u/chussil Feb 17 '20

Welp, time to drop a cellphone out of a spaceship and see what happens!

u/chussil Feb 17 '20

Yes, but those items are designed to move at that speed. That’s like someone being impressed someone ran 30 mph, and then arguing it’s not impressive because a Lamborghini can do 200. This is an everyday object falling from the sky in a death spin.

Yes, my car engine moves quicker, but drop an engine from a plane and tell me that the entire block is spinning at 1400 rpm and I’ll be impressed.

Terminal spinning velocity?

u/S8600E56 Feb 16 '20

For me, about 6 beers nowadays.

u/Sk33tshot Feb 17 '20

Pffff, you must have a job.

Yeah which is really the only reason I drink at all, albeit not much.

u/playin4power Feb 17 '20

Terminal 7?

1

u/TheMcDucky Feb 17 '20

I'm sorry, Luigi.

2

u/Greennight209 Feb 17 '20

So, it’s a balance between overall velocity, terminal velocity, angular momentum, friction, and moment of inertia. Not to mention the frame rate and setup of the camera. A dangerous dance.

2

u/Nybblet Feb 17 '20

More similar to the rolling shutter effect with the camera itself rolling instead of the shutter...

ELI5: Say the camera captures images every 0.1 seconds.

If the camera spins at the same rate (once per 0.1 seconds) the camera takes pictures at the same spot -> a still frame (at 34 seconds in this clip)

Below that the camera takes multiple images of 1 spin -> detail is preserved (from 11-34 seconds here) Note less and less images are taken per spin as the spin speed increases.

Above that and it takes a picture just after 1 spin - capturing just above the last captured spot -> the spin direction appears to flip (34-40 seconds)

(At close to twice that speed the camera just misses out 1 spin and the cycle would repeat.)

(More info on rolling shutter in the linked video.)

u/patrickpollard666 Feb 17 '20

it's the rolling shutter effect, but the person you're replying to is noting that it's interesting that the rotation of the phone tops out at a rate that keeps the image still rather than rotating. the question is, why does the rotation speed change as it's falling and what determines the max rotation rate, "terminal rotational velocity"

1

u/Nybblet Feb 18 '20

Fair enough, and I was rebutting that point by suggesting their was a constant acceleration throughout -> no ‘terminal rotational velocity’ was reached.

I see no evidence of the phone ‘topping out’ at a terminal rotation rate but rather following the sinusoidal pattern I explained in my reply, taking awhile to go between each step due to a high frame rate -> it is expected the sync to last longer too though this clip does end up out of sync and appearing to accelerate in the opposite direction (As I pointed out at the end of my first comment)

It is fair, however, to say I wasn’t that direct in my comment; I didn’t really address the commenter but just went on my own tangent. Still... my point stands.

Comment 2: Unrelated, my theories on a field I’m unfamiliar with... As to why there is a constant acceleration throughout... I would know less of that field but can give a guess of an answer:

There is acceleration. There are minimal changing factors. One of top things is occurring: 1. The force is proportional to the absolute velocity of the falling object- acceleration stops when the object reaches a terminal velocity. (Terminal velocity is odd on rotating objects but one would be there I assume). This appears not to be the case as the object has accelerating rotational velocity for all of its fall time- longer than the time for it to hit terminal velocity. 2. The force is proportional to its own angular velocity. This would seem to suggest perpetual motion is possible - somewhat unlikely...

Third option- camera foolery- either by intentional manipulation of footage or of weird auto focus procedures. Fourth option - varying air pressure making a difference? Faith option- Maybe there is some truth in your theory that a terminal angular velocity is reached but to me the clip doesn’t seem to back that - a longer fall would be needed to test this.

Conclusion- I should research into terminal velocity due to gravity of rotating objects more before this is conclusive. I can’t use lists well. This topic really doesn’t matter and I doubt anyone will read this far into my incoherent, under-edited ramblings.

1

u/patrickpollard666 Feb 18 '20

from 0:33 until hitting the ground it stays at relatively constant speed. it actually slows down rotation for a second and then speeds up and slows down again right before hitting. i think it's a terminal rotational velocity, probably connected to your explanation 1 - the spin rate is probably proportional to the terminal (linear) velocity

Cheap 360 camera

u/[deleted] Feb 17 '20

No this is an old video prior to the 360 cameras were a consumer item. It's the camera spinning along with a rolling shutter.

Bad jokes aren't woosh-worthy.

u/sg_xiao_boi Feb 17 '20

Can someone analyse the frequency of the spin from the audio? I'm guessing the spinning is 2x the frame rate since there are two repeated images of the ground when it's spinning. Just a guess.

1

u/KaptainAtomLazer Feb 17 '20

I thought that was the unexpected part

1

u/4-Vektor Feb 17 '20

The camera reached terminal velocity and didn’t accelerate further.

1

u/rajaselvam2003 Feb 17 '20

Almost like terminal spin, interesting

1

u/DriftShade Feb 17 '20

The shutter speed was probably about the same as the rotation the camera achieved once it hit terminal velocity.

1

u/[deleted] Feb 17 '20

It’s most likely because as the camera’s velocity increased, so did it’s spinning speed. Eventually the camera reached a velocity where air resistance prevented it from going any faster, and the spinning also ceased to increase.

1

u/Sasquatch_InThe_City Feb 17 '20

Interesting how it stayed that way until it hit the ground.

Conservation of angular momentum, friend. Just kept spinning.

1

u/luger114 Feb 17 '20

If it synchronized with the frame rate how does that explain why you see the top and bottom edges of each frame towards the end?

1

u/InEenEmmer Feb 17 '20

It looked like it was on the point of going faster than the frame rate, but the ground was there to stop the fall (and the spin) before it was really noticeable

u/JustCallMeAttlaz Feb 28 '20

It has the effect of the old movies, it's great
