A mirror ball spun twenty-five times too fast, shot at 400 frames a second

The rig needed reinforcing after testing because the torque was, in the DP's words, "really quite something". Then it needed a custom snoot so the light beam stayed narrower than the ball.

Billy Abbott shot "Little Bit Brighter" for director Charlotte Meling, and the set piece is a mirror ball driven far past its normal speed.

Technical lead at Window Zebra Media, Sam Kemp, custom-rigged a mirror ball to spin 25x its usual speed. In our testing the torque of this construction was really quite something, and it went in for another round of reinforcements.

The snoot is the detail that makes it work. A standard beam wider than the ball spills past it and lights the room; a beam narrower than the ball keeps the source contained so only the reflections travel. At 400fps those reflections stop being a disco shimmer and become discrete moving points.

On the economics

It's the type of video a label with a new artist or a prod-co would usually very quickly raise eyebrows at on such a small budget, but the production team at Window Zebra were on board to make this as dynamic as possible.

No figure was given, so we are not printing one.
