What is Subtitle Translate?
Subtitle Translate is an advanced Openclaw Skills integration designed to streamline the localization of video content. By leveraging cloud GPU nodes, this skill allows developers and creators to translate subtitles into multiple languages and burn them directly into video files without local software installation. It handles complex tasks like timeline management, text overlays, and platform-specific compression (H.264) in the background.
The skill provides a seamless bridge between raw video uploads and production-ready 1080p MP4 exports. It is particularly effective for translating video subtitles into multiple languages for social media, educational content, and global marketing materials, significantly reducing the manual effort usually required in video editing suites.
Subtitle Translate Use Cases
- Translating a 3-minute YouTube video with English subtitles into localized Spanish content.
- Burning translated subtitles directly into MP4 files for permanent hard-coding.
- Batch processing multiple video files within a single session for rapid localization.
- Creating localized video assets for social media platforms like TikTok, YouTube, and Instagram.
- Automated subtitling for educators and content creators looking to reach global audiences.
How Subtitle Translate Works
- Establish a secure connection to the backend API using a NEMO_TOKEN or an anonymous session identifier.
- Create a unique session ID to track the project, language settings, and timeline state.
- Upload the source video file (up to 500MB) or provide a URL to the cloud render pipeline.
- Process user natural language instructions (e.g., "translate to Spanish") via the SSE (Server-Sent Events) stream.
- The cloud GPU composites video layers and applies the translated subtitle tracks.
- Execute the export workflow to generate a high-quality 1080p MP4 download link within 30-90 seconds.
Subtitle Translate Setup
To integrate Subtitle Translate with Openclaw Skills, ensure your environment is configured with the necessary API tokens.
# Set your Nemo Video API token
export NEMO_TOKEN="your_token_here"
# The skill will automatically attempt to connect
# If no token is found, it will initialize an anonymous session
Ensure that your requests include the required attribution headers: X-Skill-Source: subtitle-translate, X-Skill-Version: 1.0.0, and X-Skill-Platform.
