Automate AI Video Creation & Multi-Platform Publishing with Gemini & Creatomate

This n8n template from Intuz provides a complete end-to-end content factory to automate the entire lifecycle of creating and publishing AI-driven videos.

It transforms a single text prompt into a fully scripted, visually rich video with AI-generated images and voiceovers, then distributes it across multiple social media platforms.

Who's this workflow for?

• Content Creators & YouTubers
• Social Media Managers & Agencies
• Digital Marketers & Entrepreneurs
• Brands looking to scale video content production

Objective

• Generate viral video scripts with Gemini AI (via LangChain).
• Break scripts into structured scenes(hooks, retention, CTA).
• Create image prompts and high-quality background visuals automatically.
• Store all scenes, prompts, images, and metadata into Airtable.
• Handle file formatting, uploads, and naming automatically.
• Add error handling and retry logic for smooth execution.
• Uploading into Social Media platforms.

How it works

1. AI Script Generation: The workflow starts with a single command. A powerful Google Gemini AI model, acting as a "Content Brain," generates a complete, viral video script with a title, description, and multiple scenes.

2. Content Management in Airtable: The entire script is broken down and saved systematically into an Airtable base, which acts as the central Content Management System (CMS) for the video production pipeline.

3. AI Image Generation: The workflow loops through each scene in Airtable. It uses an AI agent to enhance the image prompts and sends them to an image generation API (like Pollinations.ai) to create a unique, high-quality image for each scene. These images are then automatically uploaded back into Airtable.

4. Automated Video Rendering: Once all images are ready, the workflow gathers the script text and the corresponding image URLs from Airtable and sends them to Creatomate. Creatomate uses a pre-defined template to assemble the final video, complete with AI-generated voiceovers for each scene.

5. Multi-Platform Publishing: After a brief wait for the video to render, the workflow retrieves the final video file and automatically publishes it across your connected social media channels, including YouTube and Instagram.
