It never gets old. When a helicopter's propeller is perfectly synced with the camera frame rate, the result is always astounding [why it happens: [source:

The number of rotations per second matches the multiplier of the camera frame rate.

I wonder if UFO 🛸 acts the same. 🤔🤣

It does get old that you keep calling a helicopter rotor a "propeller". It's still #NotAPropeller!

It never hurts to say blades not propellers

@Loll9_val

Synced or an exact multiple of the frame rate

@Brimstone8471

Oh yes shutter speed

@g_knapp This is a seagull.

@g_knapp No no that just magic.

@rawlimark

@RhonddaBryant Brilliant ! [It's all in the Tweet - really not much reason to click on 'why it happens'...]

Amazing

as the wise Elon Musk hast stated before, nowadays, if it looks fake it’s prob real

amazing visually 🙂

very cool

Holy shit man !!

So ur saying ufos have propellers but we can't see them bc they are synced to our eyes frame rate. I think I just figured out ufos tell the government lmao

@TheTrueAmerica5 So cool.

Propeller??? Lol.

Interesting :)

This is a quantum helicopter.

Floating through the air with the greatest of ease!

@DownVideoBot

Makes for incredible viewing

That is not a propeller, it is a rotor.

Witchcraft! Be gone satan!✝️🧄
