+- Timeline creation (fine/medium/coarse)
+- Segment comparison
+- Tutorial step extraction
+
+### ✅ 3. Structured JSON Output/Schema
+**Status**: Already Implemented, Enhanced ✓  
+**Location**: `src/youtube_extension/services/ai/gemini_service.py`

+
+## Integration Steps
+
+To activate the new features:
+
+### 1. Register Routes (Required)
+
+Add to your FastAPI application (e.g., `src/youtube_extension/backend/main.py`):
+
+```python
+from src.youtube_extension.backend.api.advanced_video_routes import router as advanced_video_router
+
+app.include_router(advanced_video_router)
+```
+
+### 2. Configure Environment (Optional)
+
+```bash
+# CloudEvents Backend
+CLOUDEVENTS_BACKEND=pubsub  # or http, openwhisk, file
+
+# Pub/Sub
+GOOGLE_CLOUD_PROJECT=your-project-id
+PUBSUB_TOPIC=video-events
+
+# OpenWhisk
+OPENWHISK_API_HOST=https://openwhisk.ng.bluemix.net
+OPENWHISK_AUTH=username:password
+OPENWHISK_NAMESPACE=your-namespace
+```
+
+### 3. Run Tests
+
+```bash
+pytest tests/unit/test_cloudevents_publisher.py -v
+pytest tests/unit/test_temporal_video_analysis.py -v
+```
+
+---
+
+## Quick Start
+
+### Python SDK
+
+```python
+from src.integration.temporal_video_analysis import TemporalVideoAnalyzer
+from src.integration.cloudevents_publisher import create_publisher
+
+# Extract events
+analyzer = TemporalVideoAnalyzer()
+events = await analyzer.extract_temporal_events(
+    "https://youtube.com/watch?v=example",
+    event_types=["code_change", "api_call"]
+)
+
+# Publish to EventMesh
+publisher = create_publisher(backend="openwhisk")
+for event in events:
+    await publisher.publish(
+        source="/video-analyzer",
+        type=f"com.eventrelay.video.event.{event.event_type}",
+        data={"timestamp": event.timestamp}
+    )
+
+await analyzer.close()
+await publisher.close()
+```
+
+### REST API
+
+```bash
+# Extract events with auto-publish
+curl -X POST http://localhost:8000/api/v1/video/temporal/events \
+  -H "Content-Type: application/json" \
+  -d '{
+    "video_url": "https://youtube.com/watch?v=example",
+    "event_types": ["code_change"],
+    "publish_events": true
+  }'
+```

+
+---
+
+## Next Steps
+
+1. ✅ Review implementation
+2. ⬜ Register routes in FastAPI app
+3. ⬜ Configure environment for desired backend
+4. ⬜ Test with sample videos
+5. ⬜ Set up OpenWhisk triggers (if using)
+6. ⬜ Monitor events in EventMesh
+
