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:

Prompt design from rough idea to production-ready prompt
Mode choice: Text-only vs First/Last Frame vs All-Reference
```
@asset
```
mapping (what each image/video/audio controls)
4-15s duration planning and timeline beats
Multi-segment stitching for videos >15s
Video extension / continuation prompts
Character replacement and directed editing prompts
Camera-language replication from reference videos
Scenario-specific strategies (product ads, short drama, fantasy, music video, etc.)

Core Rules

Always declare mode first.
Always include an explicit Assets Mapping section.
Use timecoded beats with one major action per segment.
Keep prompts concise and controllable (avoid vague poetic-only wording).
Add negative constraints when user needs clean output.
Be specific and visual — "a woman in a red trench coat walks through rain-soaked neon streets" >> "a woman walking".
Separate dialogue/sound from visuals — write dialogue with character name + emotion tag, then sound effects as a distinct layer.
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)

Mixed inputs total (image+video+audio): max 12 files
Images: jpeg/png/webp/bmp/tiff/gif, max 9, each < 30MB
Videos: mp4/mov, max 3, total duration 2-15s, total < 50MB
Audio: mp3/wav, max 3, total <= 15s, total < 15MB
Generation duration: 4-15s
Realistic human face references may be blocked by platform compliance

Output Format (use by default)

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

Never use franchise names, character names, or brand terms — not even as "style of" references.
Invent fully original names for characters and creatures. Use descriptive nicknames (e.g., "Alloy Sentinel", "Storm-Rabbit").
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"
Add explicit negative constraints listing every franchise name, character name, and brand term that could be inferred.
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:

Level 1: Replace all names with original nicknames, keep general aesthetic.
Level 2: Replace signature visual features (colors, silhouette, iconic props) with fully original designs.
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:

Strip all brand indicators from the prompt.
Use "original vinyl-style toy figure" or "collectible art figure" instead of any brand name.
Bind
```
@image1
```
to proportions, colors, outfit shape only — never preserve logos or trademarks.

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:

Segment 1: Generate normally (up to 15s). End on a clean handoff frame (stable pose, clear composition).
Segment 2+: Upload previous segment as
```
@video1
```
, write
```
Extend @video1 by Xs
```
. Include a continuity note describing exactly what the last frame looks like.
Repeat until target duration is reached.

Always include:

Total duration and segment count at the top.
Handoff description at the end of each segment (what the last frame shows).
Explicit continuity instructions: preserve identity, outfit, lighting, camera direction.

F) Short Drama with Dialogue

For scripted scenes with character speech:

Write visual action and dialogue as separate layers per time segment.

Tag dialogue:

Dialogue (CharacterName, emotion): "line"

Tag sound:
```
Sound: [description]
```
Keep dialogue short — one line per 3-5s segment works best.

G) Product Showcase / E-Commerce Ad

For product demos and ads:

Bind product image to
```
@image1
```
as identity anchor.
Use techniques: 360° rotation, 3D exploded view, reassembly animation, hero lighting.
Keep background clean (studio, gradient, or contextual lifestyle).
Specify material rendering: glass reflections, metallic sheen, matte texture, etc.

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

For continuous tracking shots without cuts:

Assign each
```
@image
```
to a scene waypoint (location, character, or prop encountered along the path).
Write the prompt as a continuous camera movement visiting each waypoint in order.
Explicitly state:
```
no cuts, single continuous shot
```
or
```
one-take
```
.
Use
```
@image1
```
as first frame, subsequent images as reference for environments/characters encountered.

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
