The ABC recently launched a new video transcoding system to process all the content for ABC iview, our catch-up TV service.

Metro is a cost-efficient, scalable, cloud-based system that was built using Golang, Node, FFmpeg, and heavily utilises a variety of AWS technology including queues, varied capacity autoscaling, hosted database servers, and notifications. The system has been live since December 2015, and has successfully processed thousands of pieces of content.
