BFKK USB 3.0 HDMI SDI Dual Input Video Capturing Device

SKU CH-E6AS-JXH13

Capture 1080p60 video from HDMI or SDI sources via USB 3.0 with driver-free UVC support for OBS, Zoom and other streaming software

  • Dual HDMI and SDI inputs for flexible source switching
  • USB 3.0 interface with 360MB/s bandwidth for responsive capture
  • HDMI loop output lets you monitor the signal live
  • Driver-free operation on Windows 7 through 10 and Linux
  • Compact 69x90x24mm design fits tight streaming setups

Dual HDMI SDI input for streaming and broadcast

This BFKK capture device accepts simultaneous HDMI and SDI signals at up to 1080p60 per input. It connects through USB 3.0 with 360 MB/s bandwidth and falls back to USB 2.0 compatibility. The unit is aimed at live producers, broadcasters and streamers who need two professional sources in one compact box.

USB cable and manual included for immediate setup

The package supplies a USB 3.0 cable and a printed manual so the grabber works out of the box. Firmware updates are applied through the USB port, keeping DirectShow and UVC/UAC compliance current. No separate driver installation is required on supported Windows and Linux systems.

Dual input limited to 1080p30 when both active

When HDMI and SDI are captured together the USB 3.0 bus caps the combined throughput at 1080p30. Single-source captures still reach 1080p60. Buyers needing concurrent dual 1080p60 streams should look for a higher-bandwidth interface.

Questions about this item

Will the USB 3.0 cable or HDMI loop port need replacing after heavy daily streaming?

The included USB 3.0 cable and HDMI loop port are solid-state connections with no moving parts, so they do not wear out under normal streaming loads.

What is the first limitation I hit when capturing both HDMI and SDI sources continuously?

The USB 3.0 bus caps simultaneous dual-input capture at 1080p30, so that frame-rate ceiling appears before thermal or bandwidth limits.

How much heat and fan noise should I expect when the device runs all day?

The unit has no fan and operates silently; its aluminium case stays within the 0–50 °C working range during continuous use.
