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:
node {baseDir}/tools/generate.js \
--mode text-to-video \
--prompt "<enhanced prompt>" \
--duration <seconds> \
--aspect-ratio <ratio>
Image-to-video:
node {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:
{
"success": true,
"mode": "text-to-video",
"videoUrl": "https://...",
"duration": 5,
"aspectRatio": "16:9"
}
Send videoUrl to the user.
