Q: 6. I cannot get a feed with SDI at 59.97fps. Transmitter and receiver say 60pfs and my decklink says its receiving 30fps. Any help?

A: The Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System will only output an even frame rates of 24, 25, 30, 50, 60. It cannot output 29.97 or 59.94. If your system requires 29.97 or 59.94, the signal from the receiver will not be compatible, unless a frame rate converter is used. A scaler such as the Blackmagic Design Mini Converter UpDownCross HD, could help to convert the frame rate appropriately. https://bhpho.to/3Qd2icc
