Important Notes About SD Card Speed
Please ensure your chosen SD card is UHS-1 only (for Video Assist) or UHS-II (for Video Assist 4K). The above list are the SD cards we have currently tested, however there are many other available SD cards which will be compatible. It’s worth testing your card’s speed using Blackmagic Disk Speed Test to accurately measure whether your SD card will be able to record at the rate you require. Blackmagic Disk Speed Test uses data to simulate the storage of video so you can get results similar to what you’ll see when capturing video to an SD card.
