While we are on a showreel run it would be remiss of us not to point you in the direction of The Marmalade 2012 showreel.
See how The Marmalade got those shots with their custom made Spike camera rig:
Our groundbreaking High Speed Motion Control System ‘Spike’ brings the creative freedom of a moving camera to the world of high speed filming and so enables us to create shots that would be impossible to achieve otherwise.
‘Spike’ can freely move the camera with unparalleled speed and precision, thereby removing the previously existing creative limitation of having to shoot high speed sequences with a locked camera.
