Muse Video Prompt
Format lock: Aspect ratio 16:9 (source 1920x1080, 60 fps; generate at 1920x1080, 30 fps) — the output MUST use exactly this 16:9 horizontal ratio; no cropping, no reframing, no letterbox change.

Master (include with every clip):
Identity & costume lock: The rider — one man seen ONLY from behind or three-quarter back view, his face never visible: short brown hair, a light grey-white t-shirt, black cycling shorts, riding a slim road bicycle, pedaling posture leaned forward over the bars. He never turns around, never stops, never looks at the camera. No other people anywhere.
World & scenes: ONE impossible painterly landscape in a single unbroken vista. THE WALL CITY — a single colossal cliff, hundreds of meters tall, curving in a great arc from the left horizon along the coast to the right foreground, its entire face built into a terraced city: dense dark blue-green vegetation and stacked buildings, thousands of tiny warm orange lit windows, several white spires and temple towers standing before the cliff face, thin white waterfalls streaking down it, and a columned temple crowning the cliff top at the upper right. Below the wall: slopes of pink-lavender flowering terraces and a tiny red-roofed town. At frame left, a deep cobalt-blue bay and coastline. At mid-right, a long multi-arched stone aqueduct bridge crossing toward the wall, a small sleek blue train gliding across it. Foreground: a vivid green grassy hillside with a narrow dirt path. Everything is rendered as lush digital painting with visible soft brushwork — NOT photorealistic, NOT 3D-game render.
CAMERA — transcribed from the original: ONE continuous tracking shot, no cuts anywhere. The camera follows the rider along the hill: it pans right and pushes in as he rides past close to the lens, then settles into a steady follow-behind tracking shot as he rides away down the path. The rider's size curve is the shot: about 10 percent of frame height at the start, swelling to about 40 percent as he passes the camera at roughly one-third through, then shrinking to about 20 percent by the end. The wall city scrolls slowly leftward with parallax the whole time.
THE RHYTHM & FORCE: the wonder is SCALE and parallax — a human the size of an ant pedaling steadily beneath a city built into a single cliff. His pedaling is calm and constant, real-time speed; nothing rushes and nothing idles. If the cliff becomes ordinary buildings, if the rider ever faces the camera, if any cut appears, it is wrong.
EMOTION ARC: quiet awe — the tiny rider crosses the bottom of an impossible world and rides away into it; the film ends wider and calmer than it began.
Lighting & grade: bright midday sun from the upper left, crisp shadows, a hyper-saturated painterly grade: cobalt sea, azure sky with towering white cumulus, acid-green grass, the dark blue-green wall city punched with orange windows. Highlights bloom only in the clouds.
Music & sound: a fast, driving upbeat electronic track with a pulsing beat, synthesized; soft wind and faint rolling tire and chain sounds under it; no dialogue, no singing.

Clip 1 (source 0:00–0:07.0):
[0.0–7.0s] Shot 1 — Extreme wide becoming a follow shot, ONE continuous tracking move (pan right + push-in, then follow-behind), no cut: the rider enters small at the lower left (about 10 percent of frame height) pedaling up the grassy path from behind; the camera pans right and pushes in with him as the wall city scrolls left behind him — the blue train flashes across the aqueduct — and at about 2.5s he passes close by the camera, swelling to about 40 percent of frame height, three-quarter back view, wheels and pedaling legs clear; the camera then falls in behind him and tracks steadily as he rides away down the dirt path toward the aqueduct,
