3. Setup
Follow these steps to set up your ROFAVEZCO EZ-SP12HVC video capture device:
- Connect HDMI Input: Connect your HDMI source (e.g., game console, camera, PC) to the HDMI IN port on the capture device using an HDMI cable.
- Connect HDMI Output (Loopout): Connect an HDMI display (e.g., TV, monitor) to the HDMI OUT port on the capture device using an HDMI cable. This provides a pass-through signal for real-time viewing.
- Connect to Computer: Connect the capture device to your computer's USB 3.0 port using the provided USB 3.0 cable. The device will be recognized as a UVC (USB Video Class) device, requiring no additional drivers.
- Power Connection: The device is typically powered via the USB 3.0 connection. If additional power is needed, connect a Micro USB cable to the POWER port and a 5V DC power source.
4. Operation
Once connected, the EZ-SP12HVC operates as a standard UVC device. You can use various third-party software for video capture and streaming.
4.1 Using with Capture Software
Popular software like OBS Studio, AMCap, or other UVC-compatible applications can be used. Follow the software's instructions to select the EZ-SP12HVC as your video and audio input device.
- Video Input: Select the EZ-SP12HVC as your video capture device.
- Audio Input: Select the EZ-SP12HVC's audio input for embedded HDMI audio. Ensure your software is configured to record at 48kHz for optimal audio quality.
- Resolution and Frame Rate: Configure your software to capture at 1080p 60fps for best results. The device supports downscaling from 4K input to 1080p capture.
4.2 DIP Switch Settings
The device features a DIP switch for advanced configuration. The switches control HDCP, downscaling, and EDID settings. Refer to the diagram below and the markings on the device for specific configurations.
The DIP switches are typically numbered 1 to 4 or 1 to 5 (depending on the specific model, though the diagram shows 4). Each switch can be set to 'ON' or 'OFF'. The three control areas (HDCP, Downscaling, EDID combination) are independent.
- HDCP Control: Allows for stripping HDCP. If you encounter HDCP issues, set the relevant switch to 'TEST' mode as indicated on the device or in the manual.
- Downscaling: Enable this switch to downscale 4K input to 1080p for capture.
- EDID Settings: Configure EDID (Extended Display Identification Data) to ensure compatibility with your source and display. Options include learning EDID from the HDMI OUT, or specific presets like 4K@60Hz 4:2:0, 4K@60Hz 4:4:4, and 1080P@60Hz 2CH_3D_HDR.
Always consult the markings on the bottom of your device for the precise function of each DIP switch.
5. System Requirements
To ensure optimal performance, your computer should meet or exceed the following specifications:
- Operating System: Microsoft Windows 7/8.1/10, OS X (10.13 and above), Linux (2.6.38 and above)
- CPU: i3 Dual Core 2.8GHz or higher (Recommended PC: Intel Core i5-4440 3.10GHz + NVIDIA GeForce GTX 660 or higher; Laptop: Intel Core i7-4810MQ + NVIDIA GeForce GTX 870M or higher)
- RAM: 2GB or higher
- USB Port: USB 3.0 port (for full functionality and speed)
6. Troubleshooting
If you encounter issues with your EZ-SP12HVC, refer to the following common problems and solutions:
- No Video Output/Capture:
- Ensure all HDMI and USB cables are securely connected.
- Verify the HDMI source is active and outputting a signal.
- Check DIP switch settings, especially for HDCP. If experiencing HDCP issues, try setting the EDID to 'TEST' mode.
- Confirm your capture software is correctly configured to select the EZ-SP12HVC as the video input.
- No Audio or Poor Audio Quality:
- Ensure the EZ-SP12HVC's audio input is selected in your capture software.
- Verify the audio settings in your software are set to 48kHz.
- Check the audio output settings on your HDMI source.
- If using a front USB port on your PC, try a rear USB 3.0 port, as some front ports may have insufficient power or bandwidth, potentially causing audio stutter.
- Choppy Video or Lag:
- Ensure your computer meets the recommended system requirements, especially CPU and GPU.
- Confirm the device is connected to a USB 3.0 port. USB 2.0 ports will not provide sufficient bandwidth.
- Close unnecessary applications running in the background to free up system resources.
- If using a USB hub, try connecting the device directly to the computer's USB 3.0 port.
- Device Runs Warm:
- It is normal for the device to become warm during operation. Ensure it has adequate ventilation and is not covered.
- Compatibility Issues with Specific Software (e.g., Microsoft Teams):
- Some applications may have specific requirements or limitations. Check the application's settings for video input and resolution options.
