Generate AI short-form health videos with Gemini, Veo 3 and Google Sheets

Description

Overview

Automatically generate viral short-form health videos using AI and publish them to social platforms with n8n and Veo 3.
This workflow collects viral ideas, analyzes engagement patterns, generates AI video scripts, renders videos with Veo 3, and handles publishing and tracking fully automated, with no manual editing.

Who is this for?

This template is ideal for:

Content creators building faceless health channels (Shorts, Reels, TikTok)
Affiliate marketers promoting health products with video content
AI marketers running high-volume short-form content funnels
Automation builders combining LLMs, video AI, and n8n
Teams that want a scalable, repeatable system for viral AI video production

If you want to create health niche videos at scale without manually scripting, rendering, and uploading each video, this workflow is for you.

What problem is this workflow solving?

Creating viral short-form health videos usually involves many manual steps and disconnected tools, such as:

Manually collecting and validating viral content ideas
Writing hooks and scripts for each video
Switching between AI tools for analysis and video generation
Waiting for videos to render and checking status manually
Uploading videos and tracking what has been published

This workflow connects all these steps into a single automated pipeline and removes repetitive manual work.

What this workflow does

This automated AI health video workflow:

Runs on a defined schedule
Collects viral health content ideas from external sources
Normalizes and stores ideas in Google Sheets
Loads pending viral ideas for processing
Analyzes each idea and generates AI-optimized video scripts
Creates AI videos automatically using the Veo 3 API
Waits for video rendering and checks completion status
Retrieves the final rendered videos
Optionally aggregates or merges video assets
Publishes videos to social platforms
Updates Google Sheets with processing and publishing results

The entire process runs end-to-end with minimal human intervention.

Setup

1. Prepare Google Sheets

Create a Google Sheet to manage your content pipeline with columns such as:

idea / topic – Viral idea or source content
analysis – AI analysis or hook summary
script – Generated video script
status – pending / processing / completed / failed
video_url – Final rendered video link
publish_result – Publishing status or notes

Only rows marked as pending will be processed by the workflow.

2. Connect Google Sheets

Authenticate your Google Sheets account in n8n
Select the spreadsheet in the load and update nodes
Ensure the workflow can write status updates back to the same sheet

3. Configure AI & Veo 3

Add credentials for your AI model (e.g. Gemini or similar)
Configure prompt logic for health niche content
Add your Veo 3 API credentials
Test video creation with a small number of ideas before scaling

4. Configure Publishing & Schedule

Set up publishing credentials for your target social platforms
Open the Schedule triggers and define how often the workflow runs
The schedule controls how frequently new AI health videos are created and published

How to customize this workflow to your needs

You can adapt this workflow without changing the core structure:

Replace viral idea sources with your own research or internal data
Adjust AI prompts for different health sub-niches
Add manual approval steps before video creation
Disable publishing and use the workflow only for video generation
Add retry logic for failed renders or API errors
Extend the workflow with analytics or performance tracking

Best practices

Start with a small batch of test ideas
Keep status values consistent in Google Sheets
Focus on strong hooks for health-related content
Monitor rendering and publishing nodes during early runs
Adjust schedule frequency based on API limits
