Complete guide to using Veo 3 AI Video Prompt Generator
Learn how to create professional video prompts, understand parameter controls, and integrate with the Veo 3 API for seamless video generation.
Get started with Veo 3 AI Video Prompt Generator in just a few simple steps. This guide will walk you through the basic workflow from prompt creation to video generation.
Navigate to the main generator interface at index.html. You'll see a comprehensive form with all available parameters organized into collapsible sections.
Expand each parameter section and configure your video settings:
As you configure parameters, the tool automatically generates both JSON and text formats in real-time. You can see the live preview in the output panel on the right side.
Click the "Copy JSON" or "Copy Text" buttons to copy the generated prompt to your clipboard. Paste it directly into Veo 3's interface or API calls for video generation.
Start with one of the quick templates (Cinematic, Commercial, Documentary, or Anime) and then customize the parameters to match your specific needs.
| Parameter | Type | Options | Description |
|---|---|---|---|
| visualStyle | Select | cinematic, realistic, artistic, documentary, commercial, anime, stop-motion | Overall visual aesthetic and production style |
| mood | Select | energetic, serene, mysterious, dramatic, playful, romantic, tense | Emotional atmosphere and tone |
| theme | Text | Free text | Narrative theme and story description |
| Parameter | Type | Range | Description |
|---|---|---|---|
| cfgScale | Slider | 3-16 | Controls balance between creativity and prompt adherence |
More creative and diverse outputs, less strict adherence to prompt
Optimal balance between creativity and prompt accuracy (Recommended)
Very strict adherence to prompt, less creative variation
| Parameter | Type | Options | Description |
|---|---|---|---|
| aspectRatio | Select | 16:9, 9:16, 1:1, 21:9, 4:3 | Video aspect ratio and dimensions |
| resolutionQuality | Select | 4K, 1440p, 1080p | Video resolution and quality |
| frameRate | Select | 24fps, 30fps, 60fps | Frames per second for smoothness |
For most use cases, set CFG scale between 7-9. This provides the best balance between creative interpretation and prompt adherence.
Write clear, descriptive prompts that provide specific details about the desired outcome without being overly restrictive.
Apply professional cinematography principles to enhance your video quality and visual storytelling impact.
Optimize your prompts for faster generation and better results while maintaining quality and creative control.

Integrate Veo 3 video generation into your applications using the generated JSON prompts. The API supports both synchronous and asynchronous generation modes.
const generateVideo = async (promptData) => {
try {
const response = await fetch('https://api.veo3.google.com/v1/generate', {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({
prompt: promptData,
settings: {
quality: 'high',
timeout: 300000 // 5 minutes
}
})
});
const result = await response.json();
return result.videoUrl;
} catch (error) {
console.error('Generation failed:', error);
throw error;
}
};
const submitAsyncGeneration = async (promptData, webhookUrl) => {
const response = await fetch('https://api.veo3.google.com/v1/generate/async', {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({
prompt: promptData,
webhook: webhookUrl,
jobId: `job_${Date.now()}`
})
});
return await response.json(); // Returns job ID for tracking
};
const handleGenerationErrors = (error) => {
switch (error.code) {
case 'RATE_LIMIT_EXCEEDED':
return 'Too many requests. Please wait before retrying.';
case 'INVALID_PROMPT':
return 'Prompt validation failed. Check parameter values.';
case 'GENERATION_FAILED':
return 'Video generation failed. Try adjusting parameters.';
case 'TIMEOUT':
return 'Generation timed out. Try a simpler prompt or shorter duration.';
default:
return 'An unknown error occurred. Please try again.';
}
};
Solution: Increase resolution to 4K and ensure CFG scale is 7-9
Solution: Use specific action descriptions and consider motion blur settings
Solution: Adjust color palette to "muted" or use natural color grading
Solution: Reduce resolution to 1080p, shorten duration, or simplify the scene
Solution: Use async generation mode or reduce prompt complexity
Solution: Implement exponential backoff and batch processing
Solution: Ensure all required fields are present and values are correct types
Solution: Keep dialog under 100 characters and theme descriptions concise
Solution: Check parameter compatibility matrix in documentation
