+   - Disable MatAnyone
+   - Use gradient backgrounds
+   - Keep videos under 30 seconds
+2. **For best quality**:
+   - Use "Quality" mode
+   - Enable MatAnyone
+   - Use green screen workflow
+   - Process at full resolution
+3. **For best balance**:
+   - Use "Fast" mode
+   - Enable MatAnyone for important videos
+   - Gradient or simple backgrounds
+## 🐛 Troubleshooting
+| Issue | Solution |
+|-------|----------|
+| **Slow processing** | Switch to "Fast" or "Ultra Fast" mode |
+| **GPU not detected** | Ensure T4 GPU is enabled in Space settings |
+| **Out of memory** | Use "Ultra Fast" mode or shorter videos |
+| **Poor edges** | Enable MatAnyone refinement |
+| **Video won't play** | Check video codec compatibility |
