How to use

Connect the HDMI source (camera, console or media player) to the adapter’s HDMI input, then plug the adapter into a computer USB 3.0 port using the supplied USB cable. Open your preferred recording or streaming application and select the device as the video input. No additional drivers are typically required on supported operating systems; verify the host application settings for resolution, frame rate and audio routing as needed. For stable operation, use a USB 3.0 port directly on the host device or a high-quality powered USB hub if an onboard port is unavailable.

Recommendations

For reliable 4K capture, use a direct USB 3.0 connection to the host machine and ensure the HDMI source is set to the desired resolution and frame rate before connecting. Test the capture settings in your production software prior to live events and keep firmware and application updates current to maintain compatibility.
