  The quality of a high-definition video capture card has a lot to do with its stability.

  In order to create gimmicks, some sellers often claim that they can support 1080P/60 frames, but the high-definition video capture card actually supports 1080P/30 frames. So this is very important. You must buy a high-definition video capture card based on the resolution that supports capture. There are various types of capture cards on the Internet, but some live streaming cannot output 1080P/60 frames.

  The most important thing about high-definition video capture cards is to remember not to hot-swap them. Be sure to unplug and plug the signal cable when the device is powered off or the computer is powered off. In daily customer problems, the capture card interface is often burned due to hot swapping.

  If you want to add a USB extension cable when choosing a USB high-definition video capture card, it is best to use one with USB independent power supply to avoid insufficient power supply of the USB interface and unable to be used normally.
