Seedance 2.5 prompt recipe: locking character identity for photorealistic 30s teasers

SimplyAnnisa · x · 2026-08-21

The author shares a 30-second ultra-photorealistic teaser generated with Seedance 2.5, along with the full prompt, ready to reuse:

Format control: explicit 30s duration, 16:9 aspect ratio, "ultra-photorealistic live-action blockbuster teaser" style, with physically believable transitions between four connected locations.
Character consistency trick: @image1 serves as the only character reference, with a hard checklist locking face structure, hairstyle, hair color, skin tone, body proportions, outfit and identity—while explicitly forbidding copying the reference's background, pose, text, or studio lighting.
Second-by-second storyboard: shots are written per time block (e.g. 00:00–00:06), e.g. a handheld camera closing in inside a concrete corridor, the character glancing at the camera, inserting a brass key, then noticing the shadow under the door moving the wrong way—detail-driven actions that build narrative and suspense.
