Generate 9:16 Images from Content & Brand Guidelines

This n8n workflow streamlines the production of high-quality 9:16 aspect ratio images optimized for short-form video content and thumbnails. It begins with a manual trigger, fetches brand guidelines, style, tone, and SEO keywords from Airtable, then retrieves relevant blog posts. Using GPT-4O-MINI, it generates a 4-scene script complete with tailored image prompts.

Next, it leverages Leonardo.ai's API to create professional thumbnail images and scene-specific visuals adhering to brand standards. All generated assets, including image URLs and file sizes, are automatically stored back in Airtable for easy management and distribution.

Benefits include massive time savings in content creation, consistent branding across visuals, and scalable production for marketing teams. Ideal use cases: social media campaigns, YouTube Shorts/Reels thumbnails, TikTok video assets, and automated blog-to-video pipelines, enhancing engagement without manual design work.
