What the OZC4 capture card does

The ESTONE OZC4 is a USB 3.0 video capture device that accepts HDMI input up to 4K at 60 fps and streams 1080p at 60 fps over USB. It includes an HDMI loop-out up to 4K at 30 fps plus 3.5 mm microphone and headphone ports for live commentary. Plug-and-play operation works with OBS and similar software on Windows 7 or later, macOS 10.9 or later and Linux.

Limits of the USB 3.0 and HDMI interface

The HDMI input handles 4K at 60 fps but the loop-out is capped at 4K at 30 fps. The USB link streams at 1080p 60 fps and is compatible with both USB 2.0 and 3.0 ports, though throughput will follow the slower standard. No internal encoding or scaling hardware is described, so the host CPU carries the recording load.

Who should look elsewhere

Creators who need captured footage at 4K 60 fps over USB will not get that resolution from this device. Users requiring multi-channel audio mixing, hardware encoding or pass-through at 4K 60 fps should consider a capture card with those specifications.

Questions about this item

Should I pick the 4K version or a lower-resolution model?

This model is the 4K option; it accepts 4K at 60 fps input and passes through 4K at 30 fps while streaming 1080p at 60 fps over USB.

What does the 4K@60fps input rating mean when I plug it into my PC?

The device can receive a 4K 60 fps HDMI signal, but the USB link delivers 1080p at 60 fps to your recording or streaming software.

How does the USB 3.0 interface limit what I can capture?

The capture path runs at USB 2.0 speeds, so the maximum recorded stream is 1080p at 60 fps even though the HDMI input handles 4K at 60 fps.
