## Usage Examples

### Basic Text-to-Video Generation

```python
# Through MCP client
result = await mcp_client.call_tool("generate_video", {
    "prompt": "A majestic waterfall in a lush forest with sunlight filtering through the trees",
    "model": "veo-3.0-generate-preview"
})
```

### Image-to-Video with Local File

```python
result = await mcp_client.call_tool("generate_video_from_image", {
    "prompt": "The ocean waves gently crash against the shore",
    "image_path": "./beach_scene.jpg",
    "model": "veo-3.0-generate-preview"
})
```

### Image-to-Video with Online URL

```python
result = await mcp_client.call_tool("generate_video_from_image", {
    "prompt": "The flowers in the garden sway gently in the breeze",
    "image_path": "https://example.com/images/garden_flowers.jpg",
    "model": "veo-3.0-generate-preview"
})
```

### Creative Animation

```python
result = await mcp_client.call_tool("generate_video", {
    "prompt": "A stylized animation of a paper airplane flying through a colorful abstract landscape",
    "model": "veo-3.0-fast-generate-preview",
    "aspect_ratio": "16:9"
})
```

### Azure Blob Storage Management

```python
# List videos in Azure Blob Storage
blob_videos = await mcp_client.call_tool("list_azure_blob_videos", {})

# Upload a specific video to Azure
upload_result = await mcp_client.call_tool("upload_video_to_azure", {
    "video_path": "my_video.mp4",
    "blob_name": "custom_name.mp4"
})

# Delete a video from Azure Blob Storage
delete_result = await mcp_client.call_tool("delete_azure_blob_video", {
    "blob_name": "old_video.mp4"
})
```

## Prompt Writing Tips

### Effective Prompts
- **Be specific**: Include details about lighting, mood, camera angles
- **Describe motion**: Specify the type of movement you want
- **Set the scene**: Include environment and atmospheric details
- **Mention style**: Cinematic, realistic, animated, etc.

### Example Prompts

**Cinematic Realism:**
```
A tracking drone view of a red convertible driving through Palm Springs in the 1970s, warm golden hour sunlight, long shadows, cinematic camera movement
```

**Creative Animation:**
```
A stylized animation of a large oak tree with leaves blowing vigorously in strong wind, peaceful countryside setting, warm lighting
```

**Dialogue Scene:**
```
Close-up of two people having an intense conversation in a dimly lit room, dramatic lighting, one person gesturing emphatically while speaking
```

### Negative Prompts
Describe what you **don't** want to see:
- ❌ Don't use "no" or "don't": `"no cars"` 
- ✅ Do describe unwanted elements: `"cars, vehicles, traffic"`

## Limitations

- **Generation Time**: 11 seconds to 6 minutes depending on complexity
- **Video Length**: 8 seconds maximum
- **Resolution**: 720p output
- **Storage**: Videos are stored on Google's servers for 2 days only
- **Regional Restrictions**: Person generation defaults to "dont_allow" in EU/UK/CH/MENA
- **Watermarking**: All videos include SynthID watermarks

## 🚨 Troubleshooting

**"API key not found"**
```bash
# Set your Gemini API key
export GEMINI_API_KEY='your_api_key_here'
# Or add to .env file
echo "GEMINI_API_KEY=your_api_key_here" >> .env
```

**"Output directory not accessible"**
```bash
# Ensure the output directory exists and is writable
mkdir -p ~/Videos/Generated
chmod 755 ~/Videos/Generated
```

**"Video generation timeout"**
```bash
# Try using the fast model for testing
uvx mcp-veo3 --output-dir ~/Videos
# Then use: model="veo-3.0-fast-generate-preview"
```

**"Import errors"**
```bash
# Install/update dependencies
uv sync
# Or with pip
pip install -r requirements.txt
```

**"Azure upload failed"**
```bash
# Check your Azure connection string
echo $AZURE_STORAGE_CONNECTION_STRING

# Test Azure connection
python test_azure_blob.py

# Verify container permissions in Azure Portal
```

**"Azure Storage SDK not available"**
```bash
# Install Azure Storage SDK
pip install azure-storage-blob>=12.19.0
```

## Error Handling

The server handles common errors gracefully:

- **Invalid API Key**: Clear error message with setup instructions
- **File Not Found**: Validation for image paths in image-to-video
- **Generation Timeout**: Configurable timeout with progress updates
- **Model Errors**: Fallback error handling with detailed messages
- **Azure Connection Errors**: Graceful fallback when Azure is not configured
- **Azure Upload Failures**: Detailed error messages with troubleshooting hints
- **Container Creation**: Automatic container creation if it doesn't exist

## Development

### Running Tests

```bash
# Install test dependencies
pip install pytest pytest-asyncio

# Run tests
pytest tests/

# Test Azure Blob Storage functionality
python test_azure_blob.py
```

### Code Formatting

```bash
# Format code
black mcp_veo3.py
