For XCAM4K series, USB3.0 video output function is implemented by UVC protocol based on ISO transfer. But USB3.0 UVC output is not supported by Windows 7 or below. It could work on windows 8 and windows 10. To use the USB video output function on Windows 7 or below, users could use a USB2.0 cable or connect the USB3.0 cable to a USB2.0 port on computer. The video output is in MJPEG format and the frame rate of the video output for USB3.0 and USB2.0 will be the same.
