The Switchback Trail — Drone Chase Down a Mountain Path

Eleven-second action-sports film, 16:9, 60fps, high-energy 4K. An alpine trail at 4,000 feet: the switchbacks zigzag down a scree slope, and a lone trail runner descends at full tilt with a drone chasing from behind and above. 0-3 seconds: the chase begins at the top of the switchbacks, the runner leaning into the descent, dust kicking up on each turn, marmots whistling as the pair flashes past; the drone weaves with the switchbacks, banking hard. 3-7 seconds: fast chase cam through the hairpins, occasional whip-pans as the runner cuts the corners, scree spraying from his shoes, his shadow sharp on the pale rock; he splashes through a snowmelt stream, water exploding around his ankles, hurdles a fallen log without breaking stride, and the drone dips under a leaning pine. 7-11 seconds: the trail straightens into a final plunge, the runner opening up to a full sprint with arms pumping, the valley dropping away below in a haze of blue distance; the drone pulls slightly wide to reveal the whole zigzagging path above him, dust hanging in the air. Craft: the runner wears a bright orange singlet, black shorts, and trail shoes with a bouncing hydration vest and a number bib flapping; the trail is pale scree with switchback berms, scattered pines, and marmot burrows. Camera: fast chase cam weaving with the switchbacks, whip-pans on the hairpins, ending on a wider reveal. Lighting: hard midday sun on the scree, the runner's shadow sharp, crisp motion. Atmosphere: kinetic, breathless, joyful. Style: action-sports grade, 60fps.
