VEO3 VSL Generator & Facebook Auto-Publisher

What this workflow does

This n8n workflow automates the full process of creating a short-form Video Sales Letter (VSL) using Google VEO3, adding captions via Creatomate, and publishing the final video directly to a Facebook Page.

It's designed for creators, ecommerce brands, and marketers who want to generate and publish high-converting videos without video editing, manual uploads, or third-party tools.

Technologies used

• Google Vertex AI (VEO3) – for AI-generated video generation
• Creatomate – for dynamic captioning
• Google Cloud Storage – for video hosting (public access)
• Upload Post – for direct video publishing
• OpenAI (optional) – for script generation
• n8n – as the automation engine

Required inputs

The workflow starts from a form and expects:

• Product Name – the product or offer to promote
• Product Image – a visual representation of the product

Optional:

• Prompt override – custom prompt text if you want to bypass the AI script generation

Output

• One AI-generated vertical video (9:16), rendered via VEO3
• Captions applied automatically via Creatomate
• Final video posted to your connected Facebook Page
• File stored in Google Cloud Storage with public access
