Introduction

The Aurora1 RTC encoder is designed to deliver optimized performance for real-time communication (RTC) scenarios, providing efficient compression for AV1 streaming applications.

The Aurora1 RTC encoder offers several speed presets and rate control modes, allowing users to balance quality and bitrate requirements dynamically.

It is well-suited for applications requiring low-latency video transmission, including video conferencing, online gaming, and live broadcasts.
