# Encoder Overview

The Phenix Contribution Encoder ("Encoder") is optimized for ultra-low-latency ingest of media into the Phenix system. The Encoder accepts a wide variety of inputs, adapts them into a low-latency, high-reliability format, and exclusively outputs that content to the Phenix cloud using Phenix Interactive Transport Protocol (ITP).

The Encoder is best for latency-sensitive content, or for formats that cannot be sent over the internet or are lossy over the internet (e.g., RTSP).
