volcengine-video-generate

What This Skill Does

The volcengine-video-generate skill is a powerful tool designed for the OpenClaw AI agent to interface with the Volcengine Ark API. It enables users to synthesize video content directly from textual prompts. Beyond simple text-to-video generation, the skill supports image-to-video capabilities, allowing users to provide an initial reference frame via URL or local file path to guide the output's composition. The skill manages the complexities of API authentication, internal Base64 image conversion, and the automatic downloading of the final rendered video file, providing a seamless workflow for creators.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/warm-wm/volcengine-video-generate Ensure that you have your environment variables properly configured before execution. The skill prioritizes MODEL_VIDEO_API_KEY or ARK_API_KEY. If those are absent, it will attempt to authenticate using VOLCENGINE_ACCESS_KEY and VOLCENGINE_SECRET_KEY.

Use Cases

• Prototyping Content: Rapidly iterate through visual concepts by generating short video clips for storyboards.
• Marketing Automation: Automatically create product showcase videos by providing a high-quality static product photo as a first-frame input.
• Creative Experimentation: Use descriptive prompts to visualize abstract scenes or cinematic shots for content creation.
• Content Asset Pipeline: Programmatically generate background clips or transitions for video editors by leveraging the skill's ability to save outputs directly to specified filenames.

Example Prompts

1. "Generate a 10-second video of a futuristic cyberpunk city at night with neon lights reflecting on wet pavement. Save it as city_loop.mp4."
2. "Create a video of a flower blooming based on this image at /home/user/images/flower_start.jpg. Name the output blooming_flower.mp4."
3. "Can you make a video of a golden retriever playing fetch in the park using the image at https://example.com/dog.png? Store it as dog_fetch.mp4."

Tips & Limitations

• Performance: Generation time depends on server load and prompt complexity. Ensure your local network allows connections to the Volcengine API.
• File Paths: When using local files, ensure the OpenClaw agent has the necessary read permissions for the specified directory.
• Prompt Specificity: The quality of the video is highly dependent on the level of detail provided in the prompt. Use descriptive adjectives and stylistic cues to achieve better results.
• Authentication: Always prefer the ARK_API_KEY method for better security and stability in production environments.
