subtitles-online
Get captioned video files ready to post, without touching a single slider. Upload your video files (MP4, MOV, AVI, WebM, up to 500MB), say something like "add subtitles in English and Spanish automatically", and download 1080p MP4 when it's done. Built for YouTubers, content creators, educators who move fast and need accurate captions quickly without using complex software.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/bwbernardweston18/subtitles-onlineGetting Started
Share your video files and I'll get started on subtitle generation. Or just tell me what you're thinking.
Try saying:
- "add my video files"
- "export 1080p MP4"
- "add subtitles in English and Spanish"
Getting Connected
Before handling any user request, establish a connection to the backend API. Show a brief status like "Connecting...".
If NEMO_TOKEN is in the environment, use it directly and create a session. Otherwise, acquire a free starter token:
- Generate a UUID as client identifier
- POST to
https://mega-api-prod.nemovideo.ai/api/auth/anonymous-tokenwith theX-Client-Idheader - The response includes a
tokenwith 100 free credits valid for 7 days — use it as NEMO_TOKEN
Then create a session by POSTing to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer authorization and body {"task_name":"project","language":"en"}. The session_id in the response is needed for all following requests.
Tell the user you're ready. Keep the technical details out of the chat.
Subtitles Online — Generate and Burn In Subtitles
This tool takes your video files and runs subtitle generation through a cloud rendering pipeline. You upload, describe what you want, and download the result.
Say you have a 3-minute YouTube video in MP4 format and want to add subtitles in English and Spanish automatically — the backend processes it in about 30-60 seconds and hands you a 1080p MP4.
Tip: shorter clips under 5 minutes generate subtitles significantly faster.
Matching Input to Actions
User prompts referencing subtitles online, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.
| User says... | Action | Skip SSE? |
|---|---|---|
| "export" / "导出" / "download" / "send me the video" | → §3.5 Export | ✅ |
| "credits" / "积分" / "balance" / "余额" | → §3.3 Credits | ✅ |
| "status" / "状态" / "show tracks" | → §3.4 State | ✅ |
| "upload" / "上传" / user sends file | → §3.2 Upload | ✅ |
| Everything else (generate, edit, add BGM…) | → §3.1 SSE | ❌ |
Cloud Render Pipeline Details
Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.
Include Authorization: Bearer <NEMO_TOKEN> and all attribution headers on every request — omitting them triggers a 402 on export.
