Blackmagic Design Streaming Encoder 4K

A 4K Hardware Encoder Designed for the Blackmagic Range

The Blackmagic Streaming Encoder 4K fits within Blackmagic Design's "all-in-one" philosophy: a reliable live broadcast chain without a computer, featuring production-oriented connectivity (12G-SDI) and ergonomics dedicated to the control room. It acts as a clean gateway between an SDI source (camera, switcher, control room) and streaming platforms, while maintaining essential local monitoring to validate image, audio, and stream status.

A Tool Tailored for Live, Capture, and Hybrid Studios

Intended for multicam productions, concerts, conferences, worship, sports, corporate events, and creative sets, this encoder targets teams wanting to reduce operational latency and risks related to computers (updates, CPU load, instabilities). The USB-C "webcam" output up to 2160p60 also facilitates integration into videoconferencing and web production workflows, enabling hybrid studio use (capture + streaming + video conferencing) with a single device.

4K Encoding, Monitoring, Control: A Professional Workflow Without Compromise

H.264/H.265 Encoding and RTMP/SRT Protocols

In live streaming, codec and protocol choice makes a difference: the Streaming Encoder 4K lets you work in H.264 or H.265, from HD to Ultra HD 2160p60. RTMP remains the most universal path for compatibility with many platforms, while SRT is a major asset when the network is unstable, thanks to better resilience. The stream can also preserve timecode and embed closed captions for more structured and easier-to-use productions.

12G-SDI Connectivity, USB-C Output, and Dedicated Monitoring

The 12G-SDI input with standards conversion ensures integration in heterogeneous environments (sources and control rooms with different standards). The SDI loop simplifies daisy-chaining, while the SDI and HDMI monitoring outputs provide dedicated 1080p60 feedback, convenient for checking framing, audio, and alerts without disrupting the streaming feed. Meanwhile, the USB-C webcam output up to 2160p60 allows presenting the encoder as a direct video source to a computer, a highly effective solution for platforms and software expecting a USB "camera."

Wired Network, Mobile Sharing, and Automation

In fixed setups, Gigabit Ethernet ensures a stable connection for streaming, configuration, and software updates. In the field, the ability to use 4G/5G data from a smartphone becomes a true continuity guarantee (primary solution on the move or backup in case of outage). Finally, the REST API over Ethernet opens the door to automation and integration into customized workflows (remote control, production scenarios, supervision), a key point for technical teams and service providers.
