What This Skill Does

The HeyGen AI skill for OpenClaw provides a powerful interface for high-fidelity avatar video generation, automated presentation creation, and advanced text-to-speech synthesis. By integrating directly with the HeyGen API, this skill allows users to transform text prompts into professional talking-head videos, leverage specialized AI models for video dubbing and translation, and access programmatic video compositing tools. It acts as an abstraction layer between OpenClaw and HeyGen, handling the complexities of video status polling, asset management, and prompt engineering.

Installation

To integrate the HeyGen skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/michaelwang11394/video-agent Ensure your HeyGen API credentials are configured in your environment variables or the OpenClaw configuration file, as the skill requires valid authentication to interact with the API endpoints.

Use Cases

• Corporate Communications: Generate consistent talking-head videos for internal company updates or employee training modules.
• Marketing & Explainers: Use the Video Agent workflow to turn a simple script into a fully produced explainer video complete with visual assets and motion graphics.
• Content Localization: Utilize the video translation and dubbing features to reach global audiences by automatically translating existing video content into different languages while maintaining voice characteristics.
• Programmatic Generation: Integrate with Remotion to build data-driven, personalized video content at scale for CRM or social media marketing campaigns.
• Standalone Audio: Generate high-quality voiceover tracks using the Starfish TTS model without requiring a video container.

Example Prompts

1. "HeyGen, create a 60-second explainer video using the professional avatar ID 'avatar_01' that explains our new product launch based on this summary document."
2. "Use the Video Agent to generate a presentation video about Q3 financial results; ensure the tone is authoritative and use a blue professional background."
3. "Translate this existing video file into Spanish and generate a new version with a natural-sounding Spanish voiceover using the dubbing tool."

Tips & Limitations

• Workflow Prioritization: Always default to the Video Agent API for complex requests. It is optimized to handle structural elements like timing and visual style, which significantly reduces manual configuration effort.
• Prompt Engineering: Use the built-in prompt-optimizer.md guidelines. Well-structured prompts that explicitly define scene transitions and timing result in significantly higher quality outputs.
• Quota Management: Keep an eye on your credit usage. Video generation, particularly with high-resolution settings or long durations, consumes credits rapidly. Refer to references/quota.md to monitor limits.
• Transparent Video: If you need to composite characters onto your own backgrounds, specify WebM output formats to retain alpha transparency.
