Can the built-in HDMI capture card and USB capture card be used at the same time?
Whether the built-in HDMI capture card and USB capture card can be used at the same time depends mainly on several key factors, including computer hardware support, operating system compatibility, and the specific specifications of the capture card.
1. Computer hardware support
Slots and interfaces:
Built-in HDMI capture cards usually need to be installed on the PCI-E slot of the computer motherboard. If there is an idle PCI-E slot on the computer motherboard, then there is no problem installing the built-in HDMI capture card.
USB capture cards are connected to the computer through the USB interface, so as long as there is an available USB interface on the computer (usually USB 2.0 or higher), you can connect the USB capture card.
Power supply:
Built-in HDMI capture cards may need additional power support from the computer power supply, especially those high-performance capture cards.
USB capture cards are usually powered by the USB interface and do not require additional power supply, but this also depends on the power consumption of the capture card and the power supply capacity of the USB interface.
2. Operating system compatibility
Whether it is a built-in HDMI capture card or a USB capture card, it needs to be compatible with the computer's operating system. Most capture cards support mainstream operating systems such as Windows and MacOS, but the specific compatibility still needs to refer to the official instructions of the capture card.
3. Capture card specifications and performance
Different capture cards have different performance specifications, including supported resolution, frame rate, input interface type, etc. When using two capture cards at the same time, you need to ensure that they do not interfere with each other and can meet your application requirements.
4. Simultaneous use
If the computer hardware supports and the operating system is compatible, the built-in HDMI capture card and the USB capture card can be used at the same time. This allows you to capture video signals from two different video sources at the same time, such as one camera from the HDMI interface and the other from a device from the USB interface.
5. Precautions
When using two capture cards at the same time, you may need to install different drivers and software to control them separately. This may increase the complexity of operation.
Some advanced functions may not be available at the same time because different capture cards may have different features and limitations.
Whether the built-in HDMI capture card and the USB capture card can be used at the same time mainly depends on the support of the computer hardware, the compatibility of the operating system, and the specific specifications of the capture card. In most cases, as long as these conditions are met, the two capture cards can be used at the same time. But please note that other factors may need to be considered in actual applications, such as performance bottlenecks, operational complexity, etc.
