Use the input urban cycling video as a strict reference for both action and camera work. Retain all character movements, riding cadence, pedaling frequency, forward lean angle, hand positions, the black helmet, the dark gray cycling jacket, the black long pants, the black road bike, the wheel‑turning pattern, the rider’s position on the left side of the frame, the direction in which the road extends toward the right front, as well as the steady tracking shot and motion trajectory at waist height on the left rear—right down to the very first 0 seconds through the full 8 seconds of the original footage.
Do not alter the characters, clothing, bicycle, lens distance, framing, speed of movement, or duration; do not add edits, transitions, slow motion, additional people, vehicles, or props.
Simply replace the modern urban elevated‑bridge setting with a bright‑afternoon red sandstone canyon road: swap the light‑gray concrete guardrails and distant office buildings for towering, distinctly layered ochre‑red sandstone cliffs, scattered patches of pale desert grasses, and a dark asphalt road that winds deeper into the canyon. Keep the sky a saturated, pristine cobalt blue, with bright, penetrating sunlight, creating a sharp contrast between the red rock walls and the deep blue sky; the image should feature high contrast, rich detail, no haze, and no low‑saturation filters.
The final result should resemble the original cycling footage precisely re‑created within the canyon world: with actions and camera angles entirely unchanged, only the scene itself undergoing a seamless, coherent transformation.
