What is Video Prompt Generator?
The Video Prompt Generator is a high-performance skill designed to bridge the gap between a basic concept and a cinematic video prompt. By leveraging the NanoPhoto.AI Prompt Generator API, this skill allows users to create highly detailed, structured prompts specifically optimized for Sora 2 and other high-end video generation models.
Whether you are working with text-to-video or image-to-video workflows, this Openclaw Skills entry provides a standardized way to inject professional cinematography techniques, specific durations, and localized language support into your creative process. It is an essential utility for developers and creators building automated video production pipelines.
Video Prompt Generator Use Cases
- Converting a brief topic or scene description into a detailed, cinematic video prompt.
- Automating prompt engineering for text-to-video workflows to ensure consistent quality.
- Generating motion-specific prompts from static images for image-to-video tasks.
- Creating localized prompts across 11 supported languages for global content production.
- Planning shots with specific technical styles like slow-motion, aerial views, or long takes.
How Video Prompt Generator Works
- The user provides a core topic or scene idea (up to 500 characters) and specifies the generation mode.
- The skill selects technical parameters such as visual technique (e.g., montage, long-take) and video duration.
- For image-to-video requests, the user provides up to three public image URLs to serve as visual references.
- The skill sends a request to the NanoPhoto.AI API using the configured NANOPHOTO_API_KEY.
- The API returns a polished, professional-grade prompt which is then outputted for use in Sora 2 or other video models.
Video Prompt Generator Setup
To use this skill within the Openclaw Skills ecosystem, you must first obtain an API key from NanoPhoto.AI.
- Get your API key at nanophoto.ai/settings/apikeys.
- Configure your environment variable:
export NANOPHOTO_API_KEY="your_api_key_here"
- Alternatively, add the key to your OpenClaw configuration file located at
~/.openclaw/openclaw.jsonunder the video-prompt-generator entry.
