free-subtitle-maker from skills.volces.com

Getting Started

Welcome! Ready to add subtitles to your video for free? Upload your mp4, mov, or other video file and tell me your caption preferences — font, color, placement, or just leave it to the defaults — and I'll burn accurate subtitles directly into your footage.

Try saying:

"Add white subtitles with a black outline at the bottom of this mp4 tutorial video"
"Generate subtitles for my interview clip and use a large bold font so it's easy to read on mobile"
"Burn captions into this webm product demo — keep the style clean and minimal, centered at the bottom"

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.
