Subject locked to silver-haired warrior, intense blue eyes, scarred face, red high-collar military jacket, wielding a katana that crackles with electric-blue lightning. World rendered in high-contrast black-and-white (misty forest, shallow water floor) — ONLY the blade and its lightning stay vivid electric-blue. SECTION 1 — SHOT-BY-SHOT EFFECTS TIMELINE SHOT 1 (00:00–00:02) — Ritual Master / 24mm wide EFFECT: long-exposure light trail + slow orbit Warrior plants feet, sweeps the blue blade in a wide horizontal arc; the lightning leaves a continuous glowing ribbon orbiting the body 24mm wide, slow clockwise orbit around subject, low angle Normal speed → exits on ribbon completing the loop SHOT 2 (00:02–00:04) — Saber Ignite / 50mm profile EFFECT: bloom flash + double light-circle Blade snaps vertical; two concentric blue rings of light spin around the warrior's profile 50mm push-in, slight Dutch tilt Exits on white bloom flash SHOT 3 (00:04–00:06) — First Weave / Wrist Snap EFFECT: motion-blur whip + speed ramp (decel) Macro insert of wrist flicking the hilt; blade streaks a figure-eight blue trail, decelerating into clarity low-24mm whip, then 85mm macro on the hilt isolation Whip-pan smear connects the two SHOT 4 (00:06–00:08) — Butterfly Spin / overhead EFFECT: SIGNATURE — orbital light-ribbon halo Overhead 24mm; warrior spins, the blue blade carves a full butterfly/atom-orbit halo of crossing light rings around the body — the hero visual Camera slow descent, top-down Holds, then drops to water level SHOT 5 (00:08–00:10) — Water Trail / 50mm reflection EFFECT: reflection mirror + slow-motion (~30%) Blade tip skims the shallow water; blue light reflects and ripples, doubling the trail 50mm low, skimming water surface Slow-mo emphasizes spray SHOT 6 (00:10–00:11) — Breath Hold / 85mm portrait EFFECT: rack focus + stillness Tight portrait, eyes lower, blue glow lighting the face from below; everything quiet 85mm, shallow DOF Clean hold — contrast beat SHOT 7 (00:11–00:13) — Shore Resolve / Airborne Descent EFFECT: speed ramp (accel) + water burst Warrior leaps, lands blade-down into water; massive blue-lit spray erupts upward in a column low-24mm, fast push, slight shake on impact Burst fills frame SHOT 8 (00:13–00:15) — Lake Current / crane wide EFFECT: digital zoom-out + concentric ripple rings Crane pulls up and back; glowing blue ripple rings expand outward across the black water around the lone figure 24mm crane wide, ascending Energy resolves into stillness — final frame

How this prompt compares
The techniques this prompt uses are more common in fantasy prompts than in the library overall:
| Technique | In fantasy | Library average | Lift |
|---|---|---|---|
| orbit | 22% | 14% | 1.59x |
| volumetric | 51% | 23% | 2.23x |
| backlight | 28% | 16% | 1.72x |
Across all 5,926 prompts, the techniques used here appear at: volumetric 23%, low-key 17%, backlight 16%, orbit 14%.
The 15s duration is not arbitrary: 71% of the prompts in this library that state a duration ask for exactly 15 seconds — Seedance 2.0 accepts clips up to 15 seconds, so 15s is the model's ceiling and the most common choice.
