This is a 4K HDMI to USB 3.0 Video Capture Box, specifically model HU30A.
It functions similarly to the stick-style adapter you asked about earlier, but offers a few key upgrades. Instead of a direct stick plug, it uses a standalone metal box shell and the included blue USB 3.0 male-to-male data cable to plug into your computer.
The box states support for video inputs up to 4096 × 2160 at 60Hz, allowing you to feed in higher-quality signals from modern consoles or cameras.
The blue cable indicates true USB 3.0 connectivity. This provides faster data transfer speeds, which drastically reduces lag and video latency compared to standard USB 2.0 stick versions.
The aluminum metal body acts as a heatsink, keeping the hardware cooler and more stable during long hours of continuous live streaming or recording.
