Description

📝 Overview

This workflow leverages Google Gemini 2.0 Flash multimodal AI to automatically generate detailed descriptions of video content from any public URL. It streamlines video understanding, making it ideal for content cataloging, accessibility, and content moderation.

💡 Use Cases

• ♿ Accessibility: Automatically generate detailed video descriptions for visually impaired users.
• 🛡️ Content Moderation: Detect inappropriate or off-brand material without manual watching.
• 🗂️ Media Cataloging: Enrich your media library with automatically extracted metadata.
• 📈 Marketing & Branding: Gain fast insights into key elements, tone, and branding in video content.

⚙️ Setup Instructions

1. 🔑 Get a Gemini API Key

   • Register at ai.google.dev and create an API key.
   • Before running the workflow, set your Gemini API key as an environment variable named GeminiKey for secure access within the workflow.
   • In the Set Input node, reference this environment variable instead of hardcoding the key.

2. 🌐 Configure Video URL

   • Replace the sample URL in the Set Input node with your desired public video URL.
   • Ensure the video is directly accessible (no login or special permissions required).

3. 📝 Optional: Customize the Analysis

   • Edit the prompt in the Analyze video Gemini node to focus on the most relevant video details for your use case (e.g., branding, key actions, visual elements).

4. 🔒 Security Tip

   • Use n8n’s credentials manager or environment variables (like GeminiKey) to store your API key securely.
   • Avoid hardcoding API keys directly in workflow nodes, especially in production environments.
