📚 **Topic:** {topic}
📋 **Context:** {context if context else "None specified"}
🎬 **Scenes:** {max_scenes}

✅ **Demo Generation Complete!**

🎯 **Generated Educational Content:**
• Introduction to {topic}
• Fundamental concepts and definitions  
• Step-by-step mathematical derivation
• Visual demonstrations and proofs
• Real-world applications and examples
• Practice problems and solutions

📊 **Video Specifications:**
• Duration: ~{max_scenes * 0.8:.1f} minutes
• Scene count: {max_scenes}
• Style: Mathematical animations
