Create Video

Generate complete videos from a text prompt. Describe what you want and the AI handles script writing, avatar selection, visuals, voiceover, pacing, and captions automatically.

Authentication

All requests require the
X-Api-Key
header. Set the
HEYGEN_API_KEY
environment variable.
bash
curl -X POST "https://api.heygen.com/v1/video_agent/generate" \
  -H "X-Api-Key: $HEYGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Create a 60-second product demo video."}'

Tool Selection

If HeyGen MCP tools are available (
mcp__heygen__*
), prefer them over direct HTTP API calls — they handle authentication and request formatting automatically.
TaskMCP ToolFallback (Direct API)
Generate video from prompt
mcp__heygen__generate_video_agent
POST /v1/video_agent/generate
Check video status / get URL
mcp__heygen__get_video
GET /v2/videos/{video_id}
List account videos
mcp__heygen__list_videos
GET /v2/videos
Delete a video
mcp__heygen__delete_video
DELETE /v2/videos/{video_id}
If no HeyGen MCP tools are available, use direct HTTP API calls as documented in the reference files.

Default Workflow

Always use prompt-optimizer.md guidelines to structure prompts with scenes, timing, and visual styles.
With MCP tools:
  1. Write an optimized prompt using prompt-optimizer.mdvisual-styles.md
  2. Call
    mcp__heygen__generate_video_agent
    with prompt and config (duration_sec, orientation, avatar_id)
  3. Call
    mcp__heygen__get_video
    with the returned video_id to poll status and get the download URL
Without MCP tools (direct API):
  1. Write an optimized prompt using prompt-optimizer.mdvisual-styles.md
  2. POST /v1/video_agent/generate
    — see video-agent.md
  3. GET /v2/videos/<id>
    — see video-status.md

When to Use This Skill vs Avatar Video

This skill is for prompt-based video creation — describe what you want, and the AI handles the rest.
If the user needs precise control over specific avatars, exact scripts, per-scene voice/background configuration, or multi-scene composition, use the avatar-video skill instead.
User SaysThis SkillAvatar Video Skill
"Make me a video about X"
"Create a product demo"
"I want avatar Y to say exactly Z"
"Multi-scene video with different backgrounds"
"Transparent WebM for compositing"

Best Practices

  1. Optimize your prompt — The difference between mediocre and professional results depends entirely on prompt quality. Always use the prompt optimizer
  2. Specify duration — Use
    config.duration_sec
    for predictable length
  3. Lock avatar if needed — Use
    config.avatar_id
    for consistency across videos
  4. Upload reference files — Help the agent understand your brand/product
  5. Iterate on prompts — Refine based on results; Video Agent is great for quick iterations
