How it works

Content Discovery & Script Generation 1. Schedule Trigger: Runs daily at 6 AM or any time you choose. 2. Perplexity Search: Finds trending news articles that would make good viral content 3. Write Video Script: Uses GPT-4.1 to create a 30-second video script with hook, main content, and CTA 4. Extract URL: Parses the article URL and script data for further processing

Video Creation Pipeline 5. Get Screenshot: Uses ScreenshotOne API to create an animated scrolling video of the news article 6. Upload to Cloudinary: Temporarily stores the background video 7. Write Video Caption: Generates an engaging social media caption (150-200 characters) 8. Prepare Avatar Data: Combines all data needed for HeyGen video generation 9. Create Avatar Video: Sends request to HeyGen API to generate AI avatar video with: - Talking photo avatar - Text-to-speech voice - Background video from the news article - 720x1280 dimensions (vertical format)
