AI Talking Head Video Generator with n8n

This tutorial walks you through building an AI-powered talking head video generator that runs automatically in n8n. Instead of recording yourself, you can submit a short script or even a website URL. The system uses OpenAI to rewrite your text into a natural, concise talk track. Next, Replicate generates an audio file in your trained voice or with an AI voice. The OmniHuman model takes that audio and matches it to a still image of your choice to produce a realistic talking head video. n8n coordinates the entire process, including error handling and retries, before emailing you the final video. This makes it possible to generate a polished clip in around five minutes for under $1 per run. The build is designed to be modular, so you can adapt it to different voices, scripts, or video use cases. By the end, you’ll understand how to chain multiple AI services into a single working pipeline that produces real outputs. This is a practical way to scale video creation for marketing, product explainers, onboarding, or social media content. Once you learn the workflow, you can replicate the method for almost any video generation project.
