Videoagent Video Studio

Use when: User asks to generate a video, create a video from text, animate an image, make a short clip, or produce AI video.

Generate short AI videos with 7 backends. This skill picks the right mode (text-to-video or image-to-video), enhances the prompt for best results, and returns the video URL.

How to Generate a Video

Step 1 — Choose mode and enhance the prompt

1. 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").
2. 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](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.
