description	Expert Cinema Director skill for Seedance 2.0 (ByteDance) — high-fidelity video generation using technical camera grammar and multimodal references. Supports text-to-video, image-to-video, and video extension.

🎬 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. Text-to-Video (t2v): Generate cinematic video from a Director Brief using seedance-v2.0-t2v.
2. Image-to-Video (i2v): Animate 1–9 reference images into a video using seedance-v2.0-i2v.
3. Video Extension (extend): Seamlessly continue an existing Seedance 2.0 video using seedance-v2.0-extend.
4. Multimodal Referencing: Utilize @tag system (@image1, @video1) for style, motion, and rhythm locking.
5. Audio-Visual Sync: Native high-fidelity sound generation synchronized with visual motion.
6. Temporal Consistency: Maintain character, clothing, and environment stability across shots.

🏗️ 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

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: Use "caustic patterns," "volumetric rays," or "subsurface scattering" instead of "good lighting."
3. Timecode Notation: For multi-beat scenes, use [00:00-00:05s] format to specify timing.
4. Tag References: If files provided, use: "Replicate the camera movement of @video1 while maintaining the visual style of @image1."
5. ORDER MATTERS: Tokens at the start define composition; tokens at the end define texture and micro-motion.
6. Multi-Image i2v: Provide up to 9 reference images. The model blends aspects (style, identity, environment) across all inputs.

🚀 Protocol: Using Seedance 2

Mode 1: Text-to-Video (t2v)

# Epic reveal shot
bash scripts/generate-seedance.sh \
  --subject "a hidden temple in the Andes, mist rolling through the canopy" \
  --intent "epic" \
  --aspect "16:9" \
  --duration 10 \
  --quality high \
  --view

# Tense close-up, vertical for social
bash scripts/generate-seedance.sh \
  --subject "a detective examines a cryptic clue under harsh lamp light" \
  --intent "tense" \
  --aspect "9:16" \
  --duration 5

Mode 2: Image-to-Video (i2v)

Animate one or more reference images. Up to 9 images can be supplied — the model synthesizes motion across all of them.

# Animate a single local image
bash scripts/generate-seedance.sh \
  --mode i2v \
  --file hero.jpg \
  --subject "hero strides forward, coat billowing in slow motion" \
  --intent "epic" \
  --aspect "16:9" \
  --view

# Animate from a URL
bash scripts/generate-seedance.sh \
  --mode i2v \
  --image "https://example.com/scene.jpg" \
  --subject "camera slowly pulls back to reveal the full landscape" \
  --intent "reveal" \
  --duration 10

# Multi-image blending (character + environment + style reference)
bash scripts/generate-seedance.sh \
  --mode i2v \
  --file character.jpg \
  --file environment.jpg \
  --image "https://example.com/style.jpg" \
  --subject "character walks through the environment in cinematic style" \
  --quality high

Mode 3: Extend Video

Continue an existing Seedance 2.0 video seamlessly, preserving visual style, motion, and audio.

# Extend with no new prompt (model continues naturally)
bash scripts/generate-seedance.sh \
  --mode extend \
  --request-id "abc-123-def-456" \
  --duration 10

# Extend with directional prompt
bash scripts/generate-seedance.sh \
  --mode extend \
  --request-id "abc-123-def-456" \
  --subject "camera continues to pull back, revealing the vast city below" \
  --intent "reveal" \
  --duration 10 \
  --quality high \
  --view

Async Pattern (for long jobs)

# Submit and get request_id immediately
RESULT=$(bash scripts/generate-seedance.sh --mode i2v --file photo.jpg --async --json)
REQUEST_ID=$(echo "$RESULT" | jq -r '.request_id')

# Check later
bash ../../../../core/media/generate-video.sh --result "$REQUEST_ID"

⚠️ 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." Use "The man gradually transitions from a sprint to a sudden stop, chest heaving."
• Face Stability: For consistent characters: "Maintain high character consistency, zero facial flicker, persistent clothing details."
• Extension Only Works on v2.0: --mode extend requires a request_id from a previous seedance-v2.0-t2v or seedance-v2.0-i2v job.
• Aspect Ratios: 16:9, 9:16, 4:3, 3:4 (Seedance 2.0 supports all four).
• Duration: 5, 10, or 15 seconds.
• Quality: basic (faster) or high (higher fidelity).
