Build Your Own HeyGen on AWS | AI Avatar Videos with Bedrock, Lambda & Serverless AI

Ever wondered how platforms like HeyGen generate realistic AI avatar videos?
In this video, I’ll show you how to build your own HeyGen-style AI video generator on AWS using a fully serverless, production-ready architecture.
We’ll combine Generative AI, text-to-speech, avatar rendering, and video composition—all running on AWS services you can scale, secure, and customise.

🔧 What You’ll Learn
✅ End-to-end architecture for an AI avatar video platform
✅ Using Amazon Bedrock for LLM-powered script generation
✅ Text-to-Speech with Amazon Polly or neural voices
✅ AI avatar rendering options (D-ID-style pipelines & open models)
✅ Video assembly using Lambda, Step Functions, S3 & ffmpeg
✅ Secure APIs with API Gateway
