What is Weixin Video?
Weixin Video is a specialized tool designed to bridge the gap between high-quality video production and the specific technical constraints of the WeChat platform. By leveraging a cloud rendering pipeline, this skill allows developers and content creators to transform raw video files into WeChat-ready formats without manual editing. As part of the growing ecosystem of Openclaw Skills, it provides a seamless interface for handling file types like MP4, MOV, and WebM, ensuring they are compressed to 1080p MP4 while maintaining visual integrity.
The skill is particularly valuable for users who need to move fast. By simply describing the desired outcome, the AI manages the heavy lifting of transcoding, aspect ratio adjustment, and compression. It utilizes a sophisticated backend that handles everything from session management to asynchronous rendering, making it an essential utility for anyone looking to streamline their mobile social media workflows using Openclaw Skills.
Weixin Video Use Cases
- Rapidly format and compress this video for sharing on WeChat to meet platform upload limits.
- Convert smartphone-recorded 4K footage into optimized 1080p MP4 files for social distribution.
- Batch process multiple video clips within a single session for consistent formatting.
- Add background music or text overlays to short clips using simple natural language prompts.
How Weixin Video Works
- The skill checks for a NEMO_TOKEN in the environment or generates an anonymous token via the cloud API.
- A project session is established with a unique session ID to track all editing and rendering operations.
- The user uploads a video file (up to 200MB) which is stored temporarily in the cloud rendering environment.
- Processing instructions are sent via a Server-Sent Events (SSE) stream, allowing for real-time updates on the video state.
- Upon request, the backend queues an export job on a GPU node to composite layers and apply H.264 compression.
- The skill polls the export status and provides a direct download URL once the 1080p MP4 is ready.
Weixin Video Setup
To get started with this addition to your Openclaw Skills, ensure you have your environment configured. If you have a professional account, set your token as an environment variable:
export NEMO_TOKEN="your_nemo_api_token"
If no token is found, the skill will automatically generate an anonymous token with 100 free credits that expires after 7 days. The skill also requires configuration paths located at ~/.config/nemovideo/ for session persistence.
Weixin Video Data Schema & Taxonomy
The skill utilizes a compact JSON schema to manage the video timeline and track metadata. This ensures low-latency communication during the SSE editing process.
