📽️ What this workflow does

This workflow turns a user-submitted form with country or animal names into a cinematic video with animated scenes and immersive ambient audio. Using GPT-4 for prompt generation, Dumpling AI for visual creation,& Replicate for motion animation, ElevenLabs for sound generation, and Creatomate for video stitching, it fully automates video production — from raw idea to rendered file.


🎯 What problem is this solving?

Creating engaging multimedia content can take hours. This workflow automates the entire process of ideation, design, and rendering of high-quality cinematic clips, eliminating the need for manual video editing or audio production.


👥 Who is this for?

  • Content creators and educators
  • Digital artists and storytellers
  • Marketers or YouTubers creating short-form visual content
  • No-code/AI automation enthusiasts

⚙️ Setup Instructions

✅ Step 1: Google Sheet

Create a Google Sheet with two columns:

  • Title
  • Generated videos
    Update the Sheet ID and tab name in the final node.

✅ Step 2: Google Drive

Create two folders:

  • One for ambient audio tracks
  • One for final generated videos
    Update the folder IDs in both Google Drive nodes.

✅ Step 3: Credentials Setup

Make sure all your API tokens are saved as credentials in n8n.
This workflow uses the following integrations:

  • OpenAI (GPT-4)
  • Dumpling AI (via HTTP header)
  • Replicate.com
  • ElevenLabs
  • Google Drive
  • Google Sheets
  • Creatomate

✅ Step 4: Form Fields

Ensure your trigger form includes these fields:

  • Title
  • Country 1, Country 2, Country 3, Country 4
  • Style (e.g., cinematic, epic, fantasy, noir, etc.)

🧩 How it works

  1. User Form Submission
    Kicks off the workflow with the required inputs.

  2. Format Inputs
    Combines all 4 countries/animals into a single array.

  3. GPT-4: Generate Visual Prompts
    Uses GPT-4 to create rich cinematic descriptions per animal/country.

  4. Dumpling AI: Create Images
    Each description becomes a high-quality visual.

  5. GPT-4: Create Motion Prompts
    Each image prompt is rewritten into motion-based video prompts.

  6. Replicate: Animate
    Prompts and images are sent to Replicate’s model for animation.

  7. GPT-4: Generate Sound Prompt
    Based on the style, GPT-4 creates an ambient sound idea.

  8. ElevenLabs: Create Ambient Audio
    Audio is generated and uploaded to Google Drive.

  9. Creatomate: Stitch All Media
    All 4 motion videos and the audio track are stitched into one cinematic output.

  10. Upload to Google Drive + Log to Sheet
    Final video is saved in Drive and logged in Sheets with its title and link.


🛠️ How to Customize

  • 🎨 Modify GPT prompts for different themes (e.g., horror, fantasy, sci-fi).
  • 🧠 Swap animals for characters, objects, or locations.
  • 🎧 Replace ambient sound with ElevenLabs voiceovers or music.
  • 📂 Add metadata logging (generation time, duration, tags).
  • 🧪 Try using alternative video tools like Pika Labs or Runway ML.

✅ Requirements

  • n8n self-hosted or cloud instance
  • Active accounts for: OpenAI, Dumpling AI, Replicate, ElevenLabs, Creatomate
  • Google credentials set up for Drive + Sheets

This is a perfect end-to-end automation that showcases the power of AI + automation for video storytelling.
