How to Generate a Video
Step 1 — Choose mode and enhance the prompt
- Text-to-video: Expand with subject, action, camera movement, lighting, and style. Be specific about motion (e.g. "camera slowly zooms in", "character walks left to right").
- Image-to-video: Describe the motion to apply to the image (e.g. "gentle breeze in the hair", "camera pans across the scene"). See references/prompt_guide.md for patterns.
Step 2 — Run the script
Text-to-video:
bashnode {baseDir}/tools/generate.js \ --mode text-to-video \ --prompt "<enhanced prompt>" \ --duration <seconds> \ --aspect-ratio <ratio>
Image-to-video:
bashnode {baseDir}/tools/generate.js \ --mode image-to-video \ --prompt "<motion description>" \ --image-url "<public image URL>" \ --duration <seconds> \ --aspect-ratio <ratio>
Parameters:
| Parameter | Default | Description |
|---|---|---|
--mode | text-to-video | text-to-video or image-to-video |
--prompt | (required) | Scene or motion description |
--image-url | — | Required for image-to-video; public image URL |
--duration | 5 | Length in seconds (typically 4–10) |
--aspect-ratio | 16:9 | 16:9, 9:16, 1:1, 4:3, 3:4 |
--model | auto | Model ID (e.g. kling, veo, grok, seedance); auto = proxy picks |
Other commands:
| Command | Description |
|---|---|
node tools/generate.js --list-models | List available models from the proxy |
node tools/generate.js --status --job-id <id> | Check async job status |
Step 3 — Return the result
The script returns JSON:
json{ "success": true, "mode": "text-to-video", "videoUrl": "https://...", "duration": 5, "aspectRatio": "16:9" }
Send videoUrl to the user.
Example Conversations
User: "Generate a short video of a cat walking in the rain, cinematic."
bashnode {baseDir}/tools/generate.js \ --mode text-to-video \ --prompt "A cat walking through rain, wet streets, neon reflections, cinematic lighting, slow motion, 4K" \ --duration 5 \ --aspect-ratio 16:9
User: "Animate this photo" (user uploads a landscape)
bashnode {baseDir}/tools/generate.js \ --mode image-to-video \ --prompt "Gentle clouds moving across the sky, subtle grass movement, cinematic atmosphere" \ --image-url "https://..." \ --duration 5 \ --aspect-ratio 16:9
User: "Make a 10-second vertical video of a coffee pour, slow motion."
bashnode {baseDir}/tools/generate.js \ --mode text-to-video \ --prompt "Close-up of coffee pouring into a white cup, slow motion, steam rising, soft lighting, product shot" \ --duration 10 \ --aspect-ratio 9:16
User: "Use Google Veo for a cinematic shot."
bashnode {baseDir}/tools/generate.js \ --mode text-to-video \ --model veo \ --prompt "A dragon flying through cloudy skies, cinematic lighting, 8s" \ --duration 8 \ --aspect-ratio 16:9
User: "Animate this portrait."
bashnode {baseDir}/tools/generate.js \ --mode image-to-video \ --model grok \ --prompt "Gentle smile, subtle head turn" \ --image-url "https://..." \ --duration 5
