AI-Driven YouTube Automation Workflow

I want a single, end-to-end workflow in n8n that creates YouTube videos with AI and then uploads them to my channel without manual intervention. The process should start from a simple input (for example, a keyword, prompt, or Google Sheet row), generate the script and voice-over with tools like OpenAI and ElevenLabs (or comparable services you recommend), assemble the footage with an AI video composer, add a thumbnail and metadata, and finally push everything live through the YouTube Data API.

Key deliverables
• An n8n workflow file (.json) I can import directly
• Setup notes that list every external API used, required credentials, and any paid tiers that may apply
• Clear instructions for changing input sources (e.g., swapping a Google Sheet for an Airtable base)
• A brief Loom or screen-recorded demo showing the workflow running from trigger to published video

Acceptance criteria
The workflow must (1) run unattended once triggers and credentials are set, (2) produce a complete video with title, description, tags, and thumbnail, and (3) handle basic error logging so failed runs can be retried easily.

If any extra services are needed (cloud storage, FFmpeg, puppeteer, etc.) just spell them out in the setup notes so I can budget accordingly.
