Best Practices

Poll responsibly: Check video status every 5-10 seconds, not continuously
Handle errors: Implement retry logic with exponential backoff
Cache results: Store generated videos to avoid regenerating
Use webhooks: More efficient than polling for completion
Validate inputs: Check prompt length and image formats before API calls
