🎥 End-to-End YouTube Video Automation Workflow with n8n, HeyGen & AI

Automate the entire YouTube content creation pipeline — from video idea to AI-generated avatar video, upload, metadata generation, and publishing — with zero manual intervention!

Publishing consistent, high-quality video content is essential for audience growth and monetization. But manually creating each video — researching, writing, recording, uploading, and optimizing — is slow, repetitive, and unsustainable at scale.

This workflow solves that by automating:

• ✅ Content sourcing from Google Sheets

• ✅ Avatar video creation via HeyGen
• ✅ YouTube upload and metadata
• ✅ Final publishing and status update

All done without touching a single button. Schedule it weekly and watch videos go live while you sleep.
