What it does
🧾 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 avatarid and voiceid 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.
