Seedance 2.5 demo: full prompt behind a 30-second photorealistic travel-fashion film

AravPhi · x · 2026-09-04

The author shares the complete prompt used to generate a 30-second, photorealistic travel-fashion film with Seedance 2.5.

Key techniques in the prompt:

Identity locking: opens by fixing the same woman's facial identity, hair, makeup, body proportions and jewelry, explicitly banning identity drift, face morphing and plastic CGI skin.
Cinematic parameters: 24fps, 180° shutter, natural motion blur, subtle film grain; only 24mm environmental, 35/50mm portrait and 85mm detail lenses with physically achievable camera moves.
Timed wardrobe control: three outfits bound precisely to 0-7s (New York), 7-16s (farmers market), 16-30s (California coast), switching only at 7s and 16s.
Realism constraint list: demands correct walking mechanics, hands, hair and clothing physics while forbidding duplicated people, teleporting, warped architecture, random logos and watermarks.
Audio policy: location sound only — traffic, footsteps, ocean, laughter — no dialogue, score or artificial SFX.

The prompt is a reusable template for controlling character consistency, storyboard pacing and realism in video generation.
