Bare feet on the ledge, RED floral shorts at the bottom of frame. Hands at sides. Toes curl. Right hand tosses the pink-and-white tube; it falls to a speck on the water. 2–4s Nervous tilt down, exhale, two steps back. Spoken, hyped: "Three, two, one!" 4–7s Slow-mo takeoff. Two running steps, last foot leaves the ledge. Arms out. Canyon opens below. 7–13s Real-time fall. Frame wobbles. "Woooooo!" Walls streak. Water rushes up. Pencil dive. 13–14s Feet-first splash. Bubbles swallow the lens. 14–17s Underwater, sun shafts, logs, one breaststroke, kick up. 17–19s Surface. Grabs the tube. 19–22s Bobbing, tilt up at the cliff. Spoken: "Yeah, dude! That was insane!" 22–30s Still in the water, he TURNS the camera around to himself, holding it like a selfie. WILLIAM's face now in frame, wet, excited, same energy. He looks into the lens.
