Hyper-realistic 15-second 16:9 continuous ice action. Sound ON. OPENING: Frame 1 is already ON THE ICE, mid-stride. Never a studio portrait or grey still. The person is exactly the attached portrait. Blue-white-red vertical skating suit, white blades. No other people. No on-screen text. PHYSICS — MANDATORY (this failed last time): Sea ice is heavy, thick, slow. Plates do not teleport, stretch, or explode into CGI shards for no reason. A crack opens from a real stress line and widens at a believable speed. When they step on a floe it tilts under their WEIGHT, then they recover. Jumps need a visible crouch, takeoff, flight, and a heavy landing that shakes the plate. No sliding through solid ice. No ice appearing from nowhere. Gravity always down. Camera can move, but the world stays physically consistent. 0–5s: They skate a flat sheet. ONE crack races under the blades. They hop it. The ridge behind them lifts slowly, not a firework. 5–10s: The sheet splits into TWO or THREE large floes. They commit to one plate; it rotates slowly. They skate across it. 10–15s: They jump a dark-water gap onto the next floe, land hard, then a last push onto the snowy bank. Ice behind them is a few big tilting plates — not confetti. AUDIO: blades, ice groan, crack, splash, wind. No voiceover. Duration 15s. Aspect 16:9.
