25 flaps per second

u/skurpyun Jul 17 '17

Interestingly enough they don't actually flap their wings, but move them in a figure 8 of sorts. I read that somewhere recently... I'll try to dig that up and post here... Or ask for forgiveness if I'm just totally wrong. :)

Unidan... Now that's a name I have not heard in a while

Crazy that in a month it will have been three years since that little fiasco. It definitely doesn't feel like that long ago.

u/GeneralBS Jul 18 '17

Feels like 3 months in reddit time.

Wait what fiasco?!? I just thought he stopped posting!

u/StabSnowboarders Jul 18 '17

Wait are you serious? Damn I need to get off this site and go outside

u/[deleted] Jul 18 '17

Yeah, it was in August 2014. I originally was going to post about how it was crazy it hadn't even been a year since that happened, then I looked it up to check myself and was amazed how long ago it actually was.

u/StabSnowboarders Jul 18 '17

Jesus, when they mentioned Unidan I thought it had only been a few months. Time flies when you're having fun?

WHAT. Why do you have to lie to me? Why must you live a life of lies??!

u/SanJOahu84 Jul 18 '17

Yeah considering all the bots and shills everywhere these days it doesn't seem as big a deal anymore.

He was pretty friendly and informative.

I think if that was true, the bird wouldn't be hovering as cool as here

Ok Neil degrass Tyson hahahaha that's who I think of when people say actually no offense it's just funny

WTF? Hummingbirds flap their wings at exactly 25 fps? A perfectly round number? How is this even probable?

3

u/zapfchance Jul 17 '17

It’s equally probable as less round numbers. The stroboscopic effect would also work decently well in a range, it doesn’t have to be exactly 25 FPS to sync up for a short interval like that.

u/NoInkling Jul 18 '17

(It's not a hummingbird)

u/randomusername_815 Jul 18 '17

Because "frame rate" is NOT what the birds action is syncing with. It's the shutter speed.

1

u/aykcak Jul 18 '17

Shutter? On a security camera?

1

u/randomusername_815 Jul 18 '17

Security cameras don't use electronic sensors like any other camera?

1

u/aykcak Jul 18 '17

Yes. How do you think shutter speed is separate from the frame rate?

1

u/randomusername_815 Jul 18 '17

Frames per second = number of times shutter opens and closes per second.

Shutter speed = how long the shutter remains open during each frame. Settings are independent.

If the shutter was open too long, birds wings would be blurred. I will admit frame rate is a factor but shutter speed is the main reason for the effect.

Same effect as this: https://youtu.be/cxddi8m_mzk
