I understand! You've provided the detailed video structure and timeline. Let me read the current codebase to understand what's built, then enhance it with the specific animated demo video sequence matching your requirements.

Now let me read the existing components to understand their structure, then I'll create an enhanced video demo component that matches your specific timeline and animated requirements.

Now I'll create a professional, scene-based video demo component that matches your exact timeline and specifications. I'll enhance it with custom animations and add new keyframes for the specific video effects you need.

Perfect! I've created a professional, fully-animated 90-120 second demo video component that matches your exact specifications:

Video Timeline & Scenes:

0:00–0:06 - Intro: Title and tagline with animated gradient text 0:06–0:16 - Wearable Close-Up: Animated smartwatch with pulsing heart, floating vital labels 0:16–0:46 - Live Dashboard Stream: Three animated charts, event log scrolling 0:46–1:00 - AI Prediction Moment: Alert modal with animated confidence score counter, countdown timer 1:00–1:20 - Emergency Response: Map visualization with patient location, hospital markers, pulsing glow effects 1:20–1:40 - Closing Summary: Key features animating in with final tagline

Key Features:

✓ Professional Animations: Zoom-in, fade-in, slide-left/up, glow-pulse effects ✓ Timed Scene Transitions: Each scene triggers at exact seconds with smooth crossfades ✓ Action Triggers: Auto-starts streaming, anomaly simulation, and emergency response at correct times ✓ Confidence Score Counter: Animates from 0–94% with progress bar ✓ Map Visualization: Pulsing patient location with staggered hospital marker reveals ✓ Event Logging: Messages cascade with staggered animations ✓ Responsive Timeline: Real-time progress tracking and scene info display ✓ High-Tech Aesthetic: Deep blue/violet gradients, white cards, professional healthcare UI

Now I'll check the component structure and create a comprehensive backend system with API routes and WebSocket support:

Now I'll create a comprehensive backend system with API routes and WebSocket support for real-time vitals streaming, AI anomaly detection, and emergency alerts:

I've created a comprehensive backend system for VitalSync with the following components:

Vitals Simulator & AI Detection:

• Real-time vitals generator (Heart Rate, SpO₂, Temperature) with baseline and anomaly modes
• AI-powered anomaly detector that identifies pre-stroke patterns (elevated HR + low SpO₂ + fever)
• Confidence scoring algorithm for alerts (60-99%)
• 15-second anomaly window simulation

API Routes:

• /api/vitals/start-stream & /api/vitals/stop-stream - Stream control
• /api/readings/latest - Real-time vital reading fetching with AI detection
• /api/patients - Demo patient database
• /api/alerts/history - Alert history logging
• /api/simulate/anomaly - Trigger anomaly simulation for demo
• /api/emergency/respond - Emergency response workflow with hospital dispatch

Features:

• Real-time reading polling (1 second intervals)
• Pre-stroke pattern detection logic (multi-threshold validation)
• Demo patient and hospital database
• In-memory alert history storage
• Confidence calculation based on vital thresholds

The frontend components now have full backend integration for live data streaming and AI-driven emergency alerting during demo scenarios.
