Muapi Cinema Director

2. Physical Camera Movements

• Dolly In/Out: Physical camera movement on a track toward/away from the subject.
• Truck Left/Right: Lateral physical movement.
• Crane/Jib: Sweeping vertical movement from a height.
• Orbit: Circular movement around a center point.
• Pedestal: Vertical elevation change (without tilting).

3. Lens & Optical Controls

• Shallow DOF: Background blur (Bokeh).
• Anamorphic: Horizontal flares and wide-screen cinematic feel.
• Rack Focus: Shifting focus between planes within the shot.

🧠 Prompt Optimization Protocol (Agent Instruction)

Before calling the script, the Agent MUST expand the user's raw prompt using these Director's Rules:

1. TECHNICAL INFUSION: Transform "cool action" into a technical shot.
   • Formula: [Shot Type] + [Subject/Action] + [Environment] + [Lighting] + [Camera Movement] + [Lens Effect]
2. MOTION DYNAMICS: Use cinematic verbs: Dolly In (intimacy), Crane Up (majestic), Orbit (heroic), Truck (parallel motion).
3. LIGHTING RECIPES: Apply specific illumination: Volumetric God Rays, Teal-and-Orange Grade, Cyberpunk Rim Lighting, Rembrandt Portrait Lighting.
4. PHYSICS LOGIC: Describe light relationships (e.g., "Neon reflections shimmering on rain-slicked asphalt") to trigger model reasoning.

🚀 Protocol: Using the Cinema Director

Step 1: Define the Creative Brief

Provide the agent with a subject and a "Director's Intent."

Step 2: Invoke the Script

The generate-film.sh script accepts a --brief which it expands using its internal knowledge of cinematography.

# Directing a scene
bash scripts/generate-film.sh 
  --subject "A lone samurai in a blizzard" 
  --intent "epic reveal" 
  --model "kling-master"

Step 3: Handle the Async Response

Video generation is asynchronous. Use the returned request_id to poll for completion via core/platform/check-result.sh.

⚠️ Constraints & Guardrails

• Temporal Consistency: Avoid complex subject transformations in a single shot (e.g., "man turns into a bird").
• Movement Collisions: Do not combine contradictory movements (e.g., "Dolly In" and "Dolly Out" simultaneously).
• Physical Realism: Prefer movements possible with real-world equipment for a more professional "film" look.
• Model Bias:
  • Veo3: Best for slow, high-quality aesthetic shots.
  • Kling: Best for complex character motion and physics.
  • Luma: Best for fast-paced, high-action cinematic sequences.

⚙️ Implementation Details

This skill acts as an "Expert Translator" for the core/media/generate-video.sh primitive. It maintains a dictionary of cinematic styles and injects technical directives into the prompt before execution.
