Capture Card with 4K Loop-Out

The ESTONE OZC4 captures HDMI video at up to 4K@60fps and passes a 4K@30fps loop-through to a display. It records or streams at 1080p@60fps over USB 3.0 and works with Windows 7, 8, 10, Mac OS X 10.9+, and Linux. The device targets streamers, gamers, and conference users who need a simple plug-and-play capture solution.

Aluminium Shell and 3.5mm Audio Ports

A compact aluminium alloy housing keeps the unit light and durable for desk or mobile use. One HDMI input and one HDMI output handle the video path, while a 3.5mm microphone input and a 3.5mm headphone output let you add live commentary and monitor audio without extra adapters. USB 3.0 and USB 2.0 compatibility means it connects to most modern and older ports.

Upgrades Basic USB 2.0 Grabbers

This card replaces simple capture dongles that top out at 1080p@30fps and lack loop-through or audio mixing. The jump is worth it when you need 4K pass-through for a monitor, 1080p@60fps recording for smooth gameplay footage, and built-in microphone monitoring for live streams. It does not suit users who require 4K@60fps recording or internal PCIe capture.

Questions about this item

What does the USB 3.0 interface actually cap the capture resolution and frame rate at?

The USB 3.0 connection streams 1080p at 60fps, even though the HDMI input accepts 4K at 60fps and the loop-out can pass 4K at 30fps.

What physical space and ports does the aluminium-alloy capture card need to fit and connect?

It needs a free USB-A port for the 3.0 cable, one HDMI cable from the source and one HDMI cable to the display, plus a 3.5mm jack if you want microphone or headphone audio.

How is the OZC4 installed, and which step do people often miss?

Plug the USB cable into the computer, connect HDMI input and output, then select the device as a video source in OBS or similar software; the missed step is choosing the capture device in the streaming application instead of assuming it appears automatically.
