4K Input 1080p60 USB 3.0 Capture Card

This Grwibeou video capturing device accepts an HDMI signal up to 3840×2160 at 30 Hz and records or streams at 1920×1080 at 30 Hz over USB 3.0. It targets creators and gamers who need a simple way to bring a camera or console feed into OBS, PotPlayer, VLC or similar software on Windows, macOS, Android or Linux.

Bus Powered Low Latency Operation

The card draws power directly from the USB 3.0 port so no external supply is required. Manufacturer highlights describe ultra-low latency technology for immediate launch on streaming platforms, while the loop-out function passes the incoming signal through to a display without adding noticeable delay.

Loop Out And Broad Software Support

One USB output and two HDMI-compatible inputs provide a signal loop-out that lets you play on a monitor while capturing. The device works with Twitch, YouTube, OBS, Amcap, PotPlayer and VLC without proprietary drivers, and supports 8, 10 or 12 bit deep colour plus L-PCM audio.

Questions about this item

How do I hook up the USB 3.0 capture card and the HDMI loop-out, and what is the step most people miss?

Connect the source to the HDMI input, the display to the HDMI loop-out, and the card to a USB 3.0 port; the step often missed is selecting the 1920×1080@30Hz output in your streaming software so the loop-out stays active.

What part will need replacement first after months of daily streaming?

The USB 3.0 cable and the HDMI connectors endure the most plug cycles; keep spare cables rated for AWG26 and reseat connections if signal drops appear.

At what resolution and frame-rate ceiling does the capture card stop scaling up during long sessions?

The hardware caps capture at 3840×2160@30Hz input and 1920×1080@30Hz output; sustained use will not exceed those limits regardless of source settings.
