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.
