Blackmagic Design Streaming Encoder 4K — Professional H.264/H.265 Live Streaming Hardware
The Blackmagic Design Streaming Encoder 4K is a self-contained hardware encoder that delivers broadcast-quality H.264 and H.265 live streaming in HD and Ultra HD up to 2160p60 via SRT or RTMP protocols — without requiring a computer or complex streaming software. A 12G-SDI input, built-in Teranex standards conversion, and support for Ethernet, 5G, and 4G mobile data make it a complete, go-anywhere streaming solution.
For professionals seeking the best hardware encoder for live streaming 4K to YouTube, Facebook, X, or Blackmagic Cloud, the Streaming Encoder 4K eliminates the unreliability of software-based workflows. Its built-in presets for popular platforms mean you simply enter a streaming key and press "on air" — making it an ideal choice for broadcast engineers, live event producers, and remote camera operators who need a dependable SDI encoder for YouTube and Facebook streaming without dropped frames.
Designed around the proven Teranex Mini form factor, the Streaming Encoder 4K integrates cleanly into professional broadcast racks — three units fit in a single rack unit — and pairs directly with ATEM switchers for a full live production and streaming solution. The unit supports camera control, talkback, and tally signaling via SDI when used alongside the Blackmagic Streaming Decoder 4K, enabling centralized control of remote cameras across distributed production environments. A USB-C webcam output also makes this a broadcast-grade source for Zoom, Microsoft Teams, and Webex at up to 2160p Ultra HD resolution.
Key Features of the Blackmagic Streaming Encoder 4K
- H.264 and H.265 Hardware Encoding: Delivers professional broadcast-quality live streaming in HD and Ultra HD up to 2160p60 via SRT or RTMP, eliminating dropped frames and the overhead of software encoders.
- 12G-SDI Input with Teranex Standards Conversion: Accepts any HD or Ultra HD SDI signal and automatically converts it to the target streaming resolution — enabling production at higher quality than the streaming output requires.
- Ethernet and 5G/4G Phone Tethering: Connects to the internet via built-in Ethernet or a tethered smartphone (front and rear USB-C connections), with automatic failover to mobile data if the primary connection drops.
- USB-C Webcam Output: Presents the SDI source as a broadcast-quality webcam to any connected computer, enabling full-resolution 720p, 1080p, or 2160p video in Teams, Zoom, Webex, and any webcam-compatible software.
- Comprehensive Technical Monitoring Output: Outputs a graphics-based monitoring view via SDI and HDMI, including audio meters, codec data rate trend graphs, cache fill indicators, and a streaming settings summary.
- 12G-SDI Loop Output: Enables daisy-chaining to multiple Streaming Encoders so one SDI source can simultaneously stream to multiple independent services.
- Redundant AC and DC Power Inputs: Built-in AC power supply is backed by a 4-pin 12V DC input, supporting battery operation for fully redundant power in field or broadcast deployments.
- Blackmagic Streaming Utility Software: Free Mac and Windows software manages multiple encoders and decoders via USB or Ethernet, with user-configurable XML-based presets for custom platform support.
