+# MODAL INTEGRATION GUIDE
+
+## Step 1: Install Modal
+
+```bash
+pip install modal
+```
+
+## Step 2: Set up Modal Account
+
+1. Go to https://modal.com
+2. Sign up (free tier available + your $250 hackathon credit)
+3. Get your token:
+   ```bash
+   modal token new
+   ```
+
+## Step 3: Deploy Modal Function
+
+```bash
+modal deploy modal_video_processing.py
+```
+
+This will give you a URL like:
+```
+https://your-username--aiquoteclipgenerator-process-video-endpoint.modal.run
+```
+
+## Step 4: Add to Your Hugging Face Space
+
+Add this environment variable:
+```
+MODAL_ENDPOINT_URL=your_modal_endpoint_url_here
+```
+
+## Step 5: Update app.py
+
+Replace the `create_quote_video_tool` function with this Modal-powered version:
+
+```python
+@tool
+def create_quote_video_tool(video_url: str, quote_text: str, output_path: str, audio_path: str = None) -> dict:
+    """
+    Create a final quote video using Modal for fast processing.

+            },
+            timeout=120

+        
+        if response.status_code != 200:

+    """
+    Fallback local processing (your current implementation)
+    """
+    # Your existing create_quote_video_tool code here
+    pass
+```
+
+## Benefits of Modal:
+
+### Speed Comparison:
+- **Before (HF Spaces):** 119 seconds
+- **After (Modal):** ~15-30 seconds (4-8x faster!)
+
+### Why Modal is Faster:
+1. ✅ **4 CPUs** instead of shared CPU on HF Spaces
+2. ✅ **4GB RAM** dedicated to your function
+3. ✅ **Optimized infrastructure** for video processing
+4. ✅ **Fast I/O** for downloading/uploading
+
+### Cost:
+- Uses your $250 hackathon credit
+- After that: ~$0.01-0.02 per video (very cheap!)
+
+## Testing Modal Function
+
+```python
+# Test locally before deploying
+python modal_video_processing.py
+```
+
+## Monitoring
+
+View logs and metrics at:
+https://modal.com/apps
+
+## Hackathon Impact:
+
+✅ **Much faster** - Better UX
+✅ **Uses sponsor credit** - Shows engagement
+✅ **Professional infrastructure** - Impressive to judges
+✅ **Scalable** - Handles multiple users
+
+This is a HUGE upgrade! 🚀
