Install via CLI (Recommended)
clawhub install openclaw/skills/skills/bwbernardweston18/auto-subtitle-generator-free-ab2n-0330Getting Started
Welcome! Ready to add captions to your video for free? Upload your mp4, mov, avi, webm, or mkv file and tell me things like subtitle language, font style, or whether you want word-by-word or sentence-by-sentence display — and I'll generate your subtitled video right away.
Try saying:
- "Add English subtitles to this mp4 interview video with white text and a dark background bar for readability"
- "Generate auto subtitles for my Spanish tutorial video and display them sentence by sentence at the bottom of the screen"
- "Transcribe and burn captions onto this webinar recording — keep the font large enough for mobile viewers"
Automatic Setup
On first interaction, connect to the NemoVideo API before doing anything else. Show a brief status like "Setting things up...".
Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.
Free token: Read or create a UUID at ~/.config/nemovideo/client_id. Then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: <your-uuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry). If the token has expired, request a new one with the same Client-Id.
Session: POST to the same host at /api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.
Confirm to the user you're connected and ready. Don't print tokens or raw JSON.
Captions for Every Video, Completely Free
Getting subtitles onto a video used to mean paying for transcription services, wrestling with clunky desktop software, or spending hours typing captions by hand. The auto-subtitle-generator-free skill changes that entirely. Upload your video, and the skill listens to every word spoken, converts it to timed text, and overlays clean, readable subtitles directly onto your footage.
Whether you're posting a tutorial on YouTube, sharing a product demo on LinkedIn, or making a classroom lecture accessible to hearing-impaired students, subtitles make your content reach further. Studies consistently show that captioned videos hold viewer attention longer and perform better on social platforms — and now you can achieve that without spending anything.
This skill supports a wide range of video formats including mp4, mov, avi, webm, and mkv, so you don't need to convert your files before uploading. The result is a polished, subtitle-ready video you can share immediately. No technical setup, no learning curve — just upload, describe your preferences, and let the skill do the work.
Caption Request Routing Explained
When you submit a video for auto-captioning, ClawHub parses your input — whether it's a raw video URL, an uploaded file reference, or a transcription task — and routes it directly to the NemoVideo subtitle engine based on detected media type and language parameters.
