Create AI news avatar videos with Dumpling AI, GPT-4o and HeyGen

🧾 What this workflow does

This workflow automatically generates avatar-style videos from the latest AI-related news using Dumpling AI and HeyGen. It runs every hour, scrapes trending articles, turns them into 30–60 second spoken scripts with GPT-4o, and produces short avatar videos with HeyGen. Finally, it logs the final video URL in a Google Sheet.

👤 Who is this for

• Newsletters and creators who want to automate AI trend updates
• Content marketers generating short-form video content
• Product teams experimenting with AI-generated summaries
• Automation enthusiasts combining LLMs + video + trending data

⚙️ How to set up

🔐 Requirements

• Dumpling AI API Key stored securely as HTTP Header credential
• HeyGen API Key added as an HTTP Header credential
• OpenAI API Key for GPT-4o (can use GPT-4o-mini if preferred)
• Google Sheets account with one column: Video link

🛠 Step-by-step setup

1. Google Sheet Setup

   • Create a Google Sheet with a single column named: Video link

2. Update Credentials

   • Use n8n’s credential manager to add tokens for:
     • Dumpling AI
     • HeyGen
     • OpenAI
     • Google Sheets

3. Optional Customizations

   • In the "Dumpling AI: Search AI News" node, you can change "query": "AI Agent"
     to other trending keywords (e.g., "Generative AI", "Autonomous Agents", etc.)
   • Update the avatar_id and voice_id in the HeyGen request to match your preferred look/sound

🧠 How it works

1. The Schedule Trigger runs hourly.
2. Dumpling AI searches for fresh news related to "AI Agent."
3. The top 4 news links are scraped for full content.
4. Articles are merged and fed into GPT-4o via a LangChain Agent to produce a casual, conversational video script.
5. HeyGen creates a video using the script, avatar, and voice.
6. The workflow waits until the video rendering is complete.
7. Once done, the final video link is logged into Google Sheets.

🧪 Customization Ideas

• Change the interval (e.g., every 6 hours, daily)
• Swap avatar/voice in HeyGen to fit your brand
• Expand to post the video directly to social media
• Add image background or B-roll overlays using Creatomate

This is a fast, automated pipeline to create explainer-style AI news updates using real-time data and generative video tools.
