Epiphan AV.io 4K HDMI to USB 4K capture card

Product Overview

The Epiphan AV.io 4K is a plug-and-play HDMI to USB 4K capture card that brings HDMI video and audio into a computer over USB 3.0 with no driver installation. Built for AV professionals and integrators who need a portable 4K USB video grabber for streaming, recording, and conferencing, it is auto-detected as a UVC device on Windows, macOS, and Linux. It captures resolutions up to 4096 x 2160 with near-zero latency for live HDMI capture into OBS, Wirecast, Teams, Zoom, and other capture software.

Product Description

The AV.io 4K connects an HDMI source to your computer through a single USB 3.0 connection. Because it is a UVC class device, all three major operating systems auto-detect it on connection, so there is nothing to install. It captures HDMI video at up to 4096 x 2160 (DCI 4K), streaming 4K UHD at 30 fps and 1080p at 60 fps, and it can pass video through at its native resolution or scale it up or down on output to match the resolution your software expects.

The card adds only one to two frames of latency, making it suitable for live production where on-screen lag would be noticeable. It captures PCM audio embedded over HDMI at up to 24-bit 96 kHz and outputs two-channel stereo with automatic resampling at 48 kHz, encoded in 16-bit. A metal enclosure, LED status indicators, and included HDMI and USB cables make it ready for repeated field and rack use.

For SDI sources, compare the AV.io SDI+; for 1080p HDMI capture at a lower price point, see the AV.io HD+. For internal PCIe capture, the DVI2PCIe Duo is available in the Epiphan collection.
