+description: Expert Cinema Director skill for Seedance 2.0 (ByteDance) — high-fidelity video generation using technical camera grammar and multimodal references.
+---
+
+# 🎬 Seedance 2.0 Cinema Expert
+
+**The definitive skill for "Director-Level" AI video orchestration.**
+Seedance 2.0 is not a descriptive model; it is an *instructional* model. It responds best to technical cinematography, physics directives, and precise camera grammar.
+
+## Core Competencies
+
+1.  **Instructional Framework**: Moving away from "what it looks like" to "how to shoot it."
+2.  **Multimodal Referencing**: Utilizing the `@tag` system (`@image1`, `@video1`, `@audio1`) for style, motion, and rhythm locking.
+3.  **Temporal Consistency**: Maintaining character, clothing, and environment stability through instructional "persistence" prompts.
+4.  **Audio-Visual Sync**: Native high-fidelity sound generation synchronized with visual motion.
+
+---
+
+## 🏗️ Technical Specification: The Director Brief
+
+To get professional results, ALWAYS structure the prompt using this hierarchy:
+
+| Component | Instruction Type | Example |
+| :--- | :--- | :--- |
+| **Scene** | Environment + Lighting | "A rain-soaked cyberpunk street, magenta neon reflections on wet asphalt." |
+| **Subject** | Identity + Detail | "A woman in a black trenchcoat, determined focus, cinematic skin textures." |
+| **Action** | Fluid Interaction | "Walking forward through the crowd, coat billowing slightly in the wind." |
+| **Camera** | Movement + Lens | "Medium tracking shot, 35mm lens, slow dolly backward. Subtle handheld jitter." |
+| **Style** | Mood + Intent | "Cinematic epic, warm color grade, shallow DOF, rack focus to subject's face." |
+
+---
+
+## 🧠 Prompt Optimization Protocol (Agent Instruction)
+
+**The Agent MUST transform user intent into a technical "Director Brief" before execution.**
+
+1.  **Technical Grammar**: Use camera terms: *Dolly In/Out, Crane Shot, Whip Pan, Tracking Shot, Anamorphic Lens, Shallow Depth of Field*.
+2.  **Physics Directives**: Describe light behavior: Use "caustic patterns," "volumetric rays," or "subsurface scattering" instead of "good lighting."
+3.  **注文 references (Tags)**: If files are provided, refer to them explicitly: *"Replicate the camera movement trajectory of @video1 while maintaining the visual style of @image1."*
+4.  **ORDER MATTERS**: Tokens at the start define composition; tokens at the end define texture and micro-motion.
+
+---
+
+## 🚀 Protocol: Using Seedance 2
+
+### Step 1: Initialize the Brief
+Identify the cinematography style (e.g., *Epic Reveal*, *Tense Close-up*, *Slow Narrative*).
+
+### Step 2: Invoke the Expert Script
+Use the specialized script to ensure all technical metadata is passed correctly.
+
+```bash
+# Example: Generating an 'Epic Reveal' for a concept
+bash scripts/generate-seedance.sh \
+  --subject "a hidden temple in the Andes" \
+  --intent "epic" \
+  --aspect "16:9" \
+  --view
+```
+
+---
+
+## ⚠️ Constraints & Guardrails
+
+-   **No Keyword Soup**: DO NOT use "8k, masterpiece, trending." Use technical descriptions: "High-fidelity production grade, 24fps, cinematic grain."
+-   **Continuous Action**: Describe *one fluid motion*. Avoid "The man runs and then he stops and then he eats." Use "The man gradually transitions from a sprint to a sudden stop, chest heaving."
+-   **Face Stability**: If consistency is critical, include: *"Maintain high character consistency, zero facial flicker, persistent clothing details."*
+
+---
+
+## ⚙️ Implementation Details
+This skill acts as a **Cinematographic Wrapper** for the `seedance-v2.0-t2v` model via the `muapi` core. It translates low-level creative intent into high-fidelity technical instructions.
