# Smart Montage Planner

## Overview

The Smart Montage Planner is an AI-powered intelligent tool for automatic creation of montage plans based on uploaded content. It analyzes video and audio materials, identifies the best moments, and suggests optimal montage structure considering rhythm, emotions, and project goals.

This module integrates advanced machine learning models (YOLO for visual analysis), FFmpeg for media processing, and genetic algorithms for optimization to create professional-quality montage plans.

### Backend Integration (Rust/Tauri)
The module integrates with Rust backend services:
- **YOLO Integration** - Object detection and scene analysis
- **FFmpeg Processing** - Video/audio quality analysis  
- **Genetic Algorithm** - Plan optimization with adaptive mutation
- **Performance Optimization** - Parallel processing and caching

    bitrate: number;
    sharpness: number;      // 0-100
    stability: number;      // 0-100
    exposure: number;       // -100 to 100
    colorGrading: number;   // 0-100
  };
  content: {
    actionLevel: number;    // 0-100
    faces: FaceDetection[];

    subjectMovement: number;  // 0-100
    flowDirection: FlowDirection;
    cutFriendliness: number;  // 0-100
  };
}
```

### Moment Scoring
```typescript
interface MomentScore {
  timestamp: Timecode;
  duration: Duration;
  scores: {
    visual: number;         // Visual appeal
    technical: number;      // Technical quality
    emotional: number;      // Emotional impact
    narrative: number;      // Narrative value
    action: number;         // Action level
    composition: number;    // Frame composition
  };
  totalScore: number;       // 0-100
  category: MomentCategory;
  tags: string[];
}
```

### Montage Plan
```typescript
interface MontagePlan {
  id: string;
  metadata: PlanMetadata;
  sequences: Sequence[];
  totalDuration: Duration;
  style: MontageStyle;
  pacing: PacingProfile;
  qualityScore: number;
  engagementScore: number;
  coherenceScore: number;
}
```

## Usage

### Basic Setup
```typescript
import { MontagePlannerProvider } from '@/features/montage-planner'

function App() {
  return (
    <MontagePlannerProvider>
      <YourComponent />
    </MontagePlannerProvider>
  )
}
```

### Using the Main Hook
```typescript
import { useMontagePlanner } from '@/features/montage-planner/hooks'

function PlannerComponent() {
  const {

    analysis,
    plans,
    analyzeProject,
    generatePlan,

  }

  const handleCreateMarkers = (plan: MontagePlan) => {
    createMarkersFromPlan(plan)
    // Timeline markers created for plan structure
  }
}
```

## Available Styles
