duration: 0to preserve the source, then cap the length only when needed. - Audio: Use
originwhen the original audio must be retained (e.g., dialogue); useautowhen the edit changes the scene significantly. - Negative prompts: Include: “watermark, text, distortion, blurry, extra limbs”
- Production integration: Use webhooks for scalable applications instead of polling.
- Error handling: Implement retry with exponential backoff for 503 errors during high-demand periods.
