USB Capture HDMI Plus

The Magewell USB Capture HDMI Plus is the professional all-rounder in the USB Capture family — adding an HDMI loop-through output and full analogue audio in and out to the core HDMI capture capability, making it the right choice whenever a local monitor must remain connected to the source while capture is taking place. With a 297MHz HDMI receiver accepting signals up to 4K60 on both the input and loop-through, a 160 Mpixels/s FPGA processing pipeline delivering capture at up to 2048×2160 and 120fps, 3.5mm audio in and out alongside full 8-channel HDMI embedded audio, and compatibility with every major operating system and capture application with no drivers required, the USB Capture HDMI Plus covers the broadest range of real-world HDMI capture installations in the range. For AV integration, live production, video conferencing, lecture capture and any environment where the source display must stay live while capture runs — this is the model. Supplied by iView Data, authorised UK Magewell distributor, with full UK warranty and same-day dispatch from UK stock.

Core Functions & Capabilities

• HDMI Loop-Through — Capture and Display Simultaneously: The dedicated HDMI loop-through output passes the full input signal to a local monitor, projector or downstream device at up to 4K60 4:2:0 — with no added latency and no impact on capture quality. A single HDMI source feeds both the capture device and the room display from one cable run, with no splitter or distribution amplifier required.
• 297MHz HDMI Receiver — 4K Input & Loop-Through: The 297MHz receiver accepts HDMI signals up to 4096×2160 at 30fps 4:4:4/4:2:2 or 4096×2160 at 60fps 4:2:0 on both the input and loop-through — supporting 4K sources including game consoles, broadcast equipment and presentation computers, and passing that full signal simultaneously to the downstream display.
• 3.5mm Analogue Audio In & Out: Captures stereo analogue audio via the 3.5mm microphone input alongside HDMI embedded audio, and outputs the captured HDMI audio or host computer playback to a 3.5mm headphone or line output — functioning as a full USB audio card without additional hardware. Essential for production environments where analogue microphones, mixers or monitoring speakers must be integrated alongside HDMI video capture.
• Capture at up to 2048×2160 and 120fps: The 160 Mpixels/s onboard FPGA pipeline captures at resolutions up to 2048×2160 at up to 120fps — delivering 1920×1080p at up to 60fps and 1280×720p at up to 120fps via USB 3.0, with all scaling, cropping, de-interlacing and format conversion handled entirely on the device with zero host CPU usage.
• Custom EDID Support: Configurable EDID enables the device to negotiate the exact resolution and colour format required from any HDMI source — critical for professional installations where source output format must be precisely controlled and cannot be left to auto-negotiation.
• 8-Channel HDMI Embedded Audio Capture: Captures up to 8 channels of 24-bit HDMI embedded audio at up to 192kHz — delivering full multi-channel audio from the source for production and archiving workflows requiring more than stereo.

Key Features

• Universal OS & Driver-Free Operation: Works plug-and-play on Windows 10/11/Server, macOS 10.9+, Linux (x86, x64 & ARM, kernel 2.6.35+) and Chrome OS — no driver installation required for basic use on any supported platform.
• Broad Software Compatibility: Compatible with Zoom Rooms, Microsoft Teams, Skype for Business, Google Meet, GoToMeeting, OBS Studio, XSplit, VLC, QuickTime, GStreamer and all DirectShow, V4L2 and AVCaptureSession applications — including vMix and Wirecast.
• USB Bus-Powered — No External Power Required: Draws max 4.5W entirely from the USB 3.0 port — no power adapter, no mains connection, no additional cabling. Portable and field-deployable on any laptop or workstation with a USB 3.0 port.
• MWCapture SDK: Full SDK for Windows, macOS and Linux — enabling custom integrations, OEM development, signal status extraction, capture configuration and direct API access for enterprise deployments.
• USB Capture Utility: Free software for capture parameter configuration, EDID management, audio on/off toggle, device name customisation, firmware upgrade and diagnostics.
• Compact Form Factor — 98.1 × 56.8 × 17mm: Fits flat on a desk, mounts behind a monitor or ships in a field kit — substantial enough to anchor the dual-port body without moving, yet compact enough to be genuinely portable.

Ideal For

• AV Integration — Capture Without Losing the Room Display: Insert directly into any HDMI signal path in a lecture theatre, boardroom, conference room or event space — the loop-through continues to feed the room projector or display while capture runs simultaneously, with no interruption to the presentation and no additional distribution hardware required.
• Live Production — Camera Monitor & Capture: Connect a camera or hardware switcher HDMI output to the Plus and feed both a confidence monitor and a capture laptop simultaneously — a single device replacing a splitter and a separate capture card in mobile production and OB workflows.
• Video Conferencing — Professional Camera with Local Preview: Use any HDMI camera as the video conferencing input on Zoom, Teams or Google Meet while simultaneously feeding a local preview monitor via the loop-through — giving the presenter a confidence view without a second camera or display adapter.
• Gaming — Stream and Play on the Same Display: Capture 4K game console output for streaming or recording via USB while the loop-through passes the same signal to the gaming monitor with zero added latency — no compromise on gameplay display quality while the stream runs.
• Lecture Capture & Hybrid Classrooms: Capture the HDMI output from a presenter’s laptop or room PC while the loop-through continues to drive the room projector or interactive display — delivering capture for recording and remote delivery without disrupting the in-room presentation experience.
• Medical & Clinical Documentation: Capture from HDMI-equipped diagnostic and imaging equipment while the loop-through maintains the clinical display output — capturing procedure footage or diagnostic images for documentation without interrupting the clinical workflow or disconnecting the display.
