HD and Ultra HD Streaming

The Blackmagic Streaming Encoder 4K enables direct live streaming of broadcast-grade video in HD and Ultra HD formats up to 2160p60. Thanks to onboard H.264 and H.265 encoding, it delivers high efficiency and quality across SRT or RTMP protocols without relying on external computers or software. The 12G-SDI input supports all major video standards and includes Teranex standards conversion, allowing you to match incoming formats to the ideal streaming resolution automatically. You can loop through the SDI input to other devices or record simultaneously while streaming, making this ideal for studios, events, and mobile productions.

Network and Mobile Connectivity

This encoder is designed with flexible connectivity to suit any location. It includes a built-in Ethernet port for primary internet access and dual USB-C ports for phone tethering, allowing you to stream over 5G or 4G networks. The unit can prioritise Ethernet or mobile data and will automatically switch to the backup connection if the primary one fails, ensuring continuous streaming. This is especially valuable for live coverage from remote venues, outdoor events, or in field production where internet reliability varies.

Monitoring and Diagnostics

A dedicated HDMI and SDI monitoring output provides real-time diagnostic overlays that help visualise the stream’s technical performance. You can track data rate trends, cache fill, audio meters, and a six-second visual history of incoming video and audio. It also includes status readouts for SDI colour space, ancillary data, bit depth, timecode, and audio channel presence. This output can be used on professional SDI monitors or even HDMI televisions, giving both broadcast engineers and non-technical users confidence in the stream’s integrity.
