How to set it up

  1. Self-host n8n; install ffmpeg and yt-dlp on the host.
  2. Create /data/clips with write permission.
  3. Import the workflow JSON and create the editing subworkflow.
  4. Add Gemini and Gmail credentials, then test on a 5-10 minute video.

This is a plain-English summary of the project's own instructions. Commands and versions change, so always follow the current README at the source link.

Safety notes

  • Needs shell access on the n8n host (FFmpeg, yt-dlp).
  • Google Gemini API key and Gmail OAuth credentials.

General rule: open a duplicate of your project before letting any agent make changes, and read what a script does before approving it.
