Backdrop and Stilt

Backdrop went first, because his move steadies the world. He drew a pencil outline around every piece of the set and returned each one to its exact mark. "The world has to stay the same, frame to frame," he said. "Bump the hill, nudge the house, and the whole background jumps around behind the story." He locked the set into its marks. "That's my half — a world that never drifts." Then he frowned at the mid-stride puppet, which was tipping slowly forward. "But look. I've got the world rock-steady, and the puppet's still about to topple. It can't hold that pose on its own — one foot off the ground, leaning. A perfectly steady world with a wobbling puppet still gives you a jittery scene. Steadying the world is only half of holding still. That's Stilt's half."

Stilt steadied the puppet. She tucked a fine hidden wire behind the mid-stride figure, and it went rock-steady, poised and unfalling. "Backdrop holds the world still — I hold the puppet still," she said. "A puppet in a real pose can't balance itself; it needs a hidden support, frame to frame, or it wobbles and topples." She checked it from the camera's side, the wire invisible. "That's my half — a puppet that doesn't move unless you move it." Then she nodded at the set. "But my steady puppet is no good in a drifting world. If Backdrop's hill were jumping around behind it, my perfectly-held bird would still be in a jittery, sliding scene. I can only make a clean shot inside a world that's already holding still. His steady set is what my steady puppet needs to stand in."

Then they did the move that is theirs — the one neither can do alone. They steadied both at once: Backdrop marked and locked the whole world so nothing drifted, and Stilt rigged and hid a support behind the puppet so it couldn't wobble — and now the entire scene held perfectly still, world and figure alike, so that when they moved the puppet a deliberate hair for the next frame, that tiny, meant-to-happen change was the only movement in the whole picture. They showed each half alone: Backdrop's steady world with an un-rigged puppet — it toppled; Stilt's rigged puppet in an unmarked world — the background jumped. Both steadied together — and the shot was clean. "My steady world with a wobbling puppet still jitters," Backdrop said. "My steady puppet in a drifting world still jumps," Stilt said. "Together — the scene holds perfectly still, and only the movement we meant moves." One little scene, between a beaver and a stilt-bird, held so steady that the story inside it felt completely real.
