Best Practices and Tips
To maximize the potential of Veo 3 Fast, developers and content creators should consider the following best practices:
1. Crafting Effective Prompts
- Be Specific: Clearly describe the scene, actions, and desired atmosphere. The more detailed the prompt, the better the model can interpret and generate the intended video.
- Use Natural English: The model is optimized for English-language prompts. Avoid ambiguous or overly complex phrasing.
- Leverage Prompt Rewriting: Utilize the preview feature to refine prompts and preview how changes affect output quality.
Example Prompt:
``
A serene mountain landscape at sunrise, with gentle mist rolling over the hills and birds chirping softly in the background.
2. Managing API Usage
- Batch Requests: Since each API call can return up to 4 videos, batch similar prompts to maximize throughput within the rate limit.
- Monitor Latency: Plan for a minimum latency of 11 seconds per request, and anticipate longer wait times during peak periods.
- Optimize Video Length: Shorter videos (under 8 seconds) reduce costs and speed up generation.
3. Audio Integration
- Choose Audio Wisely: Decide whether your use case requires background music or sound effects. Omitting audio reduces costs by over 35%.
- Sync Considerations: With an audio-video sync error below 15 ms, you can confidently use generated videos for applications where precise timing is essential.
4. Compliance and Safety
- Respect Regional Restrictions: If your application serves users in the EU, UK, Switzerland, or MENA, ensure that person generation features are disabled.
- Plan for Data Retention: Download and store generated videos within 2 days, as files are automatically deleted from the server after this period.
- Acknowledge AI Origin: All videos are watermarked with SynthID, making it transparent that the content is AI-generated.
5. Utilizing Developer Resources
- Documentation: Reference the official Veo 3 Fast documentation for detailed API usage and integration guidance.
- Colab Notebooks: Use the provided quick-start Colab notebooks to experiment and prototype rapidly.
- Prompt Design Guides: Study the prompt design best practices to consistently achieve high-quality outputs.
