CORRECTIONS

- We did also mess around with multiples of the required frame rate (53.5 fps being twice 26.75 fps) which gives a ‘choppy’ version of the stroboscopic effect with twice as many rotors appearing. But I should have taken this out of the edit as I present it as a valid solution. Sorry! First noticed by Alnakar.

- Let me know if you spot anything else!
