Work out how much storage a recording needs per minute and per hour from its bitrate, and how many memory cards you need, free online.
About this calculator
Storage = bitrate × time ÷ 8. A 100 Mbps 4K clip uses 45 GB per hour; 24 Mbps 1080p uses about 10.8 GB per hour. Enter the codec bitrate from your camera menu and the total shooting time to plan card and drive capacity.
