In this short but interesting video a bird appears to float across this guy’s security cam because the bird’s flapping wings happened to perfectly sync with the camera’s frame rate. In his video description on YouTube he also added a brief FAQ:

 

– Camera: HIKVISION’s DS-2CD2342WD-I. 2688×1520 @ 20fps
– Yes it is a real bird. No I did not use strings
– No the footage is not edited. Yes I have YouTube slowing it down to make it easier to see
– Yes it is happening due to the capture frame rate matching the flap speed of the bird. No I did not adjust the camera for the bird
