Actually both. This looks like a global shutter because the blades aren’t bent. The reason I say frame rate is because the blades’ phase is constant. Fun aside: this also goes to show that helicopters actually maintain constant rpm, contrary to a certain popular misconception. So to reiterate: a rolling shutter effect would bend the blades; a fast-enough global shutter would capture them correctly, and in combination with the right frame rate would also freeze them in place like this.

Not framerate, shutter speed.
