Seedance 2.0 JiMeng Skill (OpenClaw / ClawHub)

# Seedance 2.0 JiMeng Skill (OpenClaw / ClawHub)

Purpose

Create high-control English prompts for **Seedance 2.0** and **Seedance 2.0 Fast** using multimodal references (image/video/audio/text).

This skill is for:

---

Core Rules

1. Always declare mode first.

2. Always include an explicit **Assets Mapping** section.

3. Use timecoded beats with one major action per segment.

4. Keep prompts concise and controllable (avoid vague poetic-only wording).

5. Add negative constraints when user needs clean output.

6. **Be specific and visual** — "a woman in a red trench coat walks through rain-soaked neon streets" >> "a woman walking".

7. **Separate dialogue/sound from visuals** — write dialogue with character name + emotion tag, then sound effects as a distinct layer.

8. **Match reference image style to video theme** — e.g., ink-wash style images for historical themes, neon renders for cyberpunk.

Platform Limits (Seedance 2.0)

Output Format (use by default)

1. **Mode**

2. **Assets Mapping**

3. **Final Prompt**

4. **Negative Constraints**

5. **Generation Settings**

Example skeleton:

Mode: All-Reference
Assets Mapping:
- @image1: first frame / identity anchor
- @video1: camera language + motion rhythm
- @audio1: optional soundtrack pacing

Final Prompt:
[ratio], [duration], [style].
0-3s: [action + camera].
3-7s: [action + transition].
7-10s: [reveal/climax + end frame].
Preserve identity and scene continuity. Use physically plausible motion and coherent lighting.

Negative Constraints:
no watermark, no logo, no subtitles, no on-screen text.

Generation Settings:
Duration: 10s
Aspect Ratio: 9:16

IP / Copyright Avoidance (Moderation-Safe Prompting)

Seedance 2.0 has platform-side content moderation. Prompts referencing recognizable franchises, characters, or brand aesthetics will be **rejected** even if no name is used. Follow these rules:

Core Principles

1. **Never use franchise names, character names, or brand terms** — not even as "style of" references.

2. **Invent fully original names** for characters and creatures. Use descriptive nicknames (e.g., "Alloy Sentinel", "Storm-Rabbit").

3. **Describe aesthetics generically** — replace recognizable signature features with original alternatives:

- ❌ "arc reactor" → ✅ "hex-light energy core"

- ❌ "yellow lightning mouse" → ✅ "tiny storm-rabbit with glowing cyan antlers"

- ❌ "red-gold armored suit" → ✅ "custom exo-suit with smooth ceramic panels"

4. **Add explicit negative constraints** listing every franchise name, character name, and brand term that could be inferred.

5. **Use family-friendly / PG-13 tone markers** — they help pass moderation.

Progressive Fallback Strategy

If a prompt is rejected, escalate distance from the source IP:

1. **Level 1**: Replace all names with original nicknames, keep general aesthetic.

2. **Level 2**: Replace signature visual features (colors, silhouette, iconic props) with fully original designs.

3. **Level 3**: Change character type entirely (e.g., humanoid hero → autonomous mech + drone; creature battle → abstract elemental spirits).

Toy / Figure Animation

When animating toy or doll references from images:

---

Special Cases

A) Extend Video

Explicitly write: `Extend @video1 by Xs`.

Use generation duration equal to the **newly added segment**, not the full final length.

B) Replace Character

Bind base motion/camera to `@video1`, bind replacement identity to `@image1`, and request strict choreography/timing preservation.

C) Beat Sync

Use `@video`/`@audio` rhythm references and lock beats by time range.

D) Text-Only Generation

Use when no reference assets are provided. Prompt must carry all visual direction: style, color palette, character descriptions, camera, and timeline beats. Especially useful for original creature/character concepts and IP-safe scenes.

E) Multi-Segment Stitching (Videos > 15s)

Seedance 2.0 max generation is **15s per segment**. For longer videos, split into chained segments:

1. **Segment 1**: Generate normally (up to 15s). End on a **clean handoff frame** (stable pose, clear composition).

2. **Segment 2+**: Upload previous segment as `@video1`, write `Extend @video1 by Xs`. Include a **continuity note** describing exactly what the last frame looks like.

3. Repeat until target duration is reached.

Always include:

F) Short Drama with Dialogue

For scripted scenes with character speech:

G) Product Showcase / E-Commerce Ad

For product demos and ads:

H) One-Take Long Shot (Multi-Image Waypoints)

For continuous tracking shots without cuts:

Scenario-Specific Strategies

| Scenario | Key Techniques | Typical Mode |

|---|---|---|

| **E-commerce / Product Ad** | 360° spin, 3D exploded view, hero lighting, clean studio BG | All-Reference |

| **Short Drama / Dialogue** | Dialogue tags with emotion, sound FX layer, actor blocking | All-Reference or First Frame |

| **Fantasy / Xianxia Animation** | Spell FX particles, martial arts choreography, energy auras | Text-only or All-Reference |

| **Science / Education** | 4K CGI, transparent anatomy, labeled zoom sequences | Text-only |

| **Music Video / Beat Sync** | Beat-locked cuts, widescreen 16:9, multi-image montage | All-Reference with @audio |

| **One-Take Tracking Shot** | Multi-image waypoints, continuous camera, no cuts | All-Reference |

| **IP-Safe Original Characters** | Invented names, unique features, explicit negative constraints | Text-only |
