Automated YouTube Thumbnail Generation with n8n

This n8n workflow automates the process of creating custom YouTube thumbnails from video URLs. It captures a video URL via a form, retrieves metadata and transcripts using Apify actors, analyzes the transcript with OpenAI’s GPT-4 to generate a detailed prompt for visual content, and then creates a minimalist thumbnail image styled in an illustration format using DALL·E. The generated image is resized to YouTube’s preferred 1280×720 resolution, providing a seamless, automated content creation pipeline ideal for creators looking to streamline their thumbnail production process.
