How It Works

  1. Story Generation – Your idea is transformed into a narrative split into scenes using DeepSeek LLM.
  2. Visuals – Each scene is illustrated with AI images via Replicate, then animated into cinematic video clips with RunwayML.
  3. Voice & Music – Narration is created using ElevenLabs (text-to-speech), while Replicate audio models generate background music.
  4. Final Assembly – All assets are merged into a professional video using Creatomate.
  5. Delivery – Everything is orchestrated by n8n, triggered from Slack with /render, and the final video link is delivered back instantly.

Workflow in Action

1. Trigger from Slack

Type your idea with /render in Slack - the workflow starts automatically.

3. Creatomate Template

⚠️ Important: You must create your own template in Creatomate.

This is a one-time setup - the template defines where the voiceover, music, and video clips will be placed.
The more detailed and refined your template is, the better the final cinematic result.
