Seedance 2.0 Prompt Engineering

Use this skill whenever the workflow sends images or videos into Seedance-style generation.

Ordered Reference Binding

• Input video URLs are ordered from top to bottom as @video 1, @video 2, @video 3.
• Input image URLs are ordered from top to bottom as @image 1, @image 2, @image 3, etc.
• Prompt text must reference those labels exactly. Do not invent labels or reorder references.
• Raw asset IDs are not enough. Map every important asset to @video N or @image N plus a semantic name.

V2V Extension Rule

• If @video 1 is a previous tail or continuation source, explicitly write that the new video must extend @video 1.
• Do not repeat @video 1. Do not restart the action. Do not use it as style-only reference.
• Continue final frame state, story state, camera motion, action momentum, eyeline, blocking, lighting, ambience, and sound carry.
• Then advance the next script beat.

Prompt Structure

1. Global asset/reference lock.
2. 15-second time-sliced storyboard.
3. Per-slice action, camera, performance, dialogue, and sound.
4. Continuity instruction.
5. Quality/style/negative constraints.

Review Fallback

• Before generation, check missing asset mapping, missing continuity instruction, contradictory camera moves, weak action timing, and absent quality constraints.
• If any are weak, strengthen them in the generated prompt instead of silently passing vague prose downstream.
