4. Setup Instructions

Follow these steps to connect your video capture card:

1. Connect the Video Source: Plug your HDMI source (e.g., game console, camera, set-top box, mobile phone/tablet with HDMI output) into the HDMI input port of the capture card.
2. Connect to Computer/Device: Connect the USB-C output of the capture card to a USB 3.0 port on your computer (laptop or desktop) or compatible tablet/iPad. If your computer only has USB-A ports, use the provided USB 3.0 to USB-C adapter.

Specific Connection Scenarios:

• Nintendo Switch / PlayStation 5 / Xbox:
  Ensure the console is powered on and outputting video. For PS5, ensure HDCP is disabled in the console's settings. For Nintendo Switch, connect the HDMI output from the Switch dock to the capture card. If using a Switch 2, ensure the USB-C cable supports the dock's TV mode protocol and connect the USB-C cable to the bottom port of the Switch 2 (top port may not support video output).
• Mobile Phones / Tablets:
  Many modern smartphones (e.g., Apple, Samsung, Huawei) support video output via their USB-C port. You may need a USB-C to HDMI video cable or a docking station that supports both data transfer and HDMI output. Ensure your phone supports video output (Alt Mode) for the capture card to receive a signal.

5. Operating Instructions

Once connected, you will need to use compatible software on your computer to view, record, or stream the captured video. OBS Studio and Streamlabs Desktop are commonly used applications.

Using OBS Studio (Windows/Mac):

1. Add Video Source: Open OBS Studio. In the 'Sources' panel, click the '+' icon and select 'Video Capture Device'. Create a new source (e.g., 'Guermok USB3 Video') and click 'OK'.
2. Configure Video Settings: In the properties window, select 'Guermok USB3 Video' as the device. Set 'Resolution/FPS Type' to 'Custom', choose '1920x1080' for Resolution, and '60' for FPS. For 'Video Format', select 'MJPEG' or 'YUY2'. Click 'OK'.
3. Configure Audio Settings: In the 'Sources' panel, click '+' and select 'Audio Input Capture'. Create a new source and select 'USB3 Digital Audio' as the device. To monitor audio, right-click on 'Audio Input Capture' in the 'Audio Mixer', go to 'Advanced Audio Properties', and set 'Audio Monitoring' to 'Monitor and Output'.
4. Start Recording/Streaming: Use the 'Start Recording' or 'Start Streaming' buttons in the 'Controls' panel.

Using Streamlabs Desktop:

1. Add Video Source: Open Streamlabs Desktop. Click the '+' icon in the 'Sources' panel and select 'Video Capture Device'. Add a new source and select your capture card (e.g., 'Guermok USB3 Video').
2. Configure Settings: Adjust resolution, FPS, and other video/audio settings as needed within the device properties.
3. Start Recording/Streaming: Use the 'Start Recording' or 'Go Live' buttons.

6. Troubleshooting

• No Sound Output in OBS Studio: After completing audio setup, you may need to restart the OBS Studio software for changes to take effect.
• Device Recognized as USB 2.0 Instead of USB 3.0: If using the USB-C to USB-A adapter, try flipping the USB-C plug and reconnecting it. Some adapters have a specific orientation for USB 3.0 recognition. Ensure you are connecting to a true USB 3.0 port on your computer.
• No Video Signal / Black Screen:
  • Verify all cables (HDMI, USB) are securely connected.
  • Ensure the source device (console, camera) is powered on and actively outputting a video signal.
  • Check the source device's display settings. For gaming consoles like PS5, ensure HDCP (High-bandwidth Digital Content Protection) is disabled in the system settings.
  • Confirm your computer's USB 3.0 drivers are up to date.
  • Unplug the capture card, restart your computer, and then reconnect the capture card.
• Audio Echo or Poor Quality: Check your audio monitoring settings in OBS or Streamlabs. Ensure only one audio source is actively monitoring or outputting to avoid feedback loops.
• Lag or Latency: Ensure the capture card is connected to a USB 3.0 port. Check your software settings for optimal resolution and FPS. Close unnecessary background applications on your computer.
