🚀 AI-Powered Space Video Generator

This Node.js project automates the creation, narration, captioning, and publishing of daily space-themed videos using AI and powerful APIs. It generates visually stunning, voice-narrated videos based on NASA’s Astronomy Picture of the Day (APOD), enhanced by AI-generated content, and uploads them automatically to YouTube.

📽️ Key Features

• 🎥 Video Generation: Built with Remotion for dynamic video rendering.
• 🧠 Script Writing: Uses Google Gemini AI to generate engaging narratives based on NASA’s daily content.
• 🖼️ Image Generation: Integrates Pollination AI to enhance or generate complementary space visuals.
• 🔊 Voice Narration: Uses AWS Polly to convert AI-generated text into lifelike narration.
• 🎙️ Captions Generation: Transcribes narration using AssemblyAI for automatic subtitles.
• 🌌 Daily Space Content: Fetches content from NASA APOD API to ensure authenticity.
• ☁️ Cloud Rendering: Scalable video rendering via Remotion Lambda.
• 📤 YouTube Upload: Publishes videos to YouTube automatically using YouTube Data API.
• 🧾 Metadata Storage: Saves video metadata (title, description, timestamps, etc.) to AWS S3.
• 🤖 Daily Automation: Orchestrated using Make (Integromat) for daily execution.
• 🌐 Deployment: Deployed on Render for fast and reliable hosting.
