Frequently Asked Questions

Veo 3.1 Lite is the cost-efficient variant of Veo 3.1. It supports 720p and 1080p resolutions (Veo 3.1 also offers 4K) and is optimized for lower-cost, high-volume generation. Use Veo 3.1 Lite for prototyping and iteration, and Veo 3.1 Standard when you need maximum fidelity or 4K output.
Veo 3.1 Lite supports 720p (HD) and 1080p (Full HD). For 4K output, use the standard Veo 3.1 model.
When generate_audio is set to true (the default), Veo 3.1 Lite synthesizes synchronized audio that matches the visual content. This includes ambient sounds, music, and effects appropriate to the scene described in your prompt.
Generation time varies based on resolution, duration, and server load. Use webhooks for production workflows to avoid polling.
Effective prompts describe the scene, subjects, motion, camera movement, lighting, and atmosphere. Be specific about visual details. Example: “A serene mountain landscape at sunset with clouds moving slowly across an orange sky, camera slowly panning right”
Yes, set aspect_ratio to "9:16" to generate vertical videos optimized for TikTok, Instagram Reels, and YouTube Shorts.

​
Best practices

  • Prompt detail: Provide specific descriptions of scenes, subjects, motion, and atmosphere for best results
  • Negative prompts: Use negative_prompt to exclude unwanted elements like “blurry, low quality, distorted”
  • Resolution selection: Choose 720p for fast iteration and 1080p for social media and final delivery
  • Audio control: Disable generate_audio if you plan to add custom audio in post-production
  • Webhook integration: Use webhooks instead of polling for scalable production applications
  • Seed for consistency: Use the same seed with identical parameters to reproduce similar results
