A secure, automated video transcoding service is built by uploading raw files to Amazon S3 via a React.js frontend. S3 triggers a Node.js Lambda function or ECS Fargate task (using ECR for container images) to run FFmpeg, converting videos into optimized HLS/DASH formats. Infrastructure is managed via Terraform, and secure, expiring links are generated using S3 signed URLs for playback.
