Seedance 2.5 Image to Video Guide — References, Motion & Continuity
A practical Seedance 2.5 image-to-video workflow: reference preparation, motion direction, camera movement, continuity locks and model-ready prompting.
Reference preparation
- Use a clean image where the subject is unambiguous.
- Decide what must remain locked: identity/product, environment, framing and lighting.
- Describe motion separately from the visible starting frame.
- Use one clear camera move instead of several conflicting moves.
- Describe the desired final state when continuity matters.
Seedance 2.5 prompt focus
Use concise action beats and clear timing. Avoid overloading one shot with unrelated transformations.
Reference frame is the exact start. 0–3s: subject stands up naturally. 3–6s: she turns toward the window. 6–8s: she takes one slow step forward. Preserve face, wardrobe, room layout and light direction.
