Using which camera, and recording codec? Uncompressed straight video output data rate is too big for a SD card. Recording to ProRes or similar codec is going to take something like a SanDisk Extreme Pro UHS2 card, if recording a UHD 4K 10-bit Video. See the BM SD card list for the Video Assist 4K for recommended cards that can record this. If you are using the Ursa Mini Pro, then check its SD recommend card list.
