Challenge film · Opening sequence · Seedance 2.5
One rider crosses the desert, draws a circle in the sand — and from a single bronze filament the monumental Horizon Gate rises. Eighteen linked shots become a thirty-second architectural opener.
Original / visual reference
Below are the same eighteen frames, cropped one by one from this sheet, in the original left-to-right, top-to-bottom order. Prompts and timing are preserved from the Seedance production bible.
Seedance 2.5 · Reference pack
Every prompt shares the same LOCKS: one traveler, one horse, one Horizon Gate, one desert hour. Prepare these masters once, then feed the matching start frame + masters into each Seedance 2.5 run so continuity survives the eighteen cuts.
Shots 02–06 · 11 · 15–18
Adult male in a simple dark hooded cloak and headscarf. Face partly concealed. Lock fabric length, wrap and silhouette — no costume drift between wide gallops and human-scale shots.
Deliver · 3–4 stills: front, ¾, side, rear silhouette against desert.
Shots 02–06 · 11 · 15–18
One dark horse with fixed proportions, mane and tack. Hoof / dust contact must read as the same animal as the wide gallops. No second horse, no modern gear.
Deliver · Side profile · low hoof detail · full body with rider mounted.
Shots 14–18
ONE monument: two asymmetrical interlocking wing shells in warm sandstone / limestone over brushed-bronze ribs; one vast OPEN central portal. No towers, glass, neon or second building.
Deliver · Hero front elevation · ¾ low angle · view through the portal · aerial footprint.
Shots 10–16
Same coordinates and compass lock. Progressive assembly only: bronze ground plan → rising ribs → ribbon weave → sand-to-stone cladding → final seam. Never redesign the silhouette mid-sequence.
Deliver · 4–5 stills matching stages 10, 11, 12, 13, 16.
Shots All 18
One Arabian basin: layered dunes, distant hazy mountains, soft pale-amber late afternoon. Fixed sun direction and color balance. No blue-sky swap, fog, rain or harsh red sunset.
Deliver · Empty valley plate (shot 05 geography) + dune ridge plate.
Shots 01 · 07–09 · 13
Tactile sand grains, fingertip groove, bronze filament, stone cladding on bronze rib, leather / cloth with sand. Stops Seedance inventing sparks, neon or glass facades.
Deliver · Sand macro · hand-in-sand · bronze thread · stone/bronze junction.
Shots 01–18
Use each mood-board crop as the image-to-video start frame. Generate slightly longer takes if the model cannot hit 1.2–2.5s, then trim in the edit to the listed cut times.
Deliver · Eighteen previz frames — one upload per Seedance generation.
Shots All 18
No second rider or horse, no cars, cities or neon towers, no on-screen title, no sci-fi glass, no floating blocks, no weather or time-of-day jump. Title LINE OF HORIZONS only in post.
Deliver · Keep the LOCKS block verbatim in every Seedance run.
Workflow tip. Generate in act order: Arrival → Mark → Build → Reveal. Keep the finished Gate master out of shots 01–09. From shot 10 onward, pin the same portal orientation. Prefer longer clean takes; trim to editorial duration in the timeline. One color grade and one sun direction for the full 30 seconds.

The first light of a warm desert afternoon grazes a shallow crest of fine sand. Individual grains flicker in restrained backlight. A soft breeze moves a thin veil of grains from left to right, exposing an otherwise untouched ripple. Do not reveal a person, horse or architecture yet. Hold a quiet, tactile opening image.
