Product Description

The Magewell USB Capture AIO is a multi-interface HD video capture device that delivers signals to a host computer through a single USB 3.0 port, with no driver installation required on Windows, Linux, macOS or Chrome OS. The device integrates HDMI 1.4a, BNC 3G-SDI, DVI-I, VGA, component video, S-Video (YC) and composite video inputs, along with analog audio input, making it suitable for broadcast, education, medical imaging, remote video conferencing and professional live streaming. The video processing pipeline reaches 160 Mpixels/s and provides hardware cropping, scaling, de-interlacing, aspect-ratio conversion, color-space conversion and frame-rate conversion, with compatibility for OBS Studio, XSplit, Zoom Rooms, Microsoft Teams and most mainstream streaming and video software.

Q&A

What video input interfaces does the USB Capture AIO support?

The device integrates seven video inputs: HDMI 1.4a, BNC 3G-SDI, DVI-I, VGA, component video, S-Video (YC) and composite video. It also supports HDMI embedded, SDI embedded and analog (3.5mm / DB9) audio inputs. HDMI and VGA require the included breakout cable or adapter.

What are the maximum supported resolutions and frame rates for HDMI and SDI?

HDMI supports up to 2048x1080 at 60fps 4:4:4; SDI supports up to 2048x1080 at 60fps 4:2:2 10-bit. Actual capture frame rate may be limited by USB bandwidth and the device's internal working frequency.

Can it be used on a Mac or Linux system?

Yes. Connected via USB 3.0, the device supports Windows 10 and above, Linux (kernel 2.6.35 and above, including x86/x64/ARM), Mac OS X 10.9 and above, macOS 10.12 and above, and Chrome OS — all without driver installation.

Is it compatible with Zoom or OBS Studio?

Yes. The device is compatible with Zoom Rooms, Microsoft Teams, Skype for Business, Google Hangouts, OBS Studio, XSplit, QuickTime Player, and all software supporting DirectShow (Windows), V4L2 (Linux) or AVCaptureSession (macOS).

How does the USB Capture AIO differ from a typical single-interface USB capture device?

A typical single-interface USB capture device usually supports only one input such as HDMI or SDI. The USB Capture AIO integrates seven video interfaces — including broadcast-grade 3G-SDI and analog composite sources — and includes a full set of breakout cables, making it ideal for professional broadcast, education, medical and exhibition applications that need to handle multiple source types simultaneously.
