Wedding Video Storage Calculator
Before a wedding, work out how much card and hard disk space you need: all cameras, all days, photos and backup copies. The tool also suggests a hard disk size.

Bitrates are typical values; check your camera's menu for the exact one.
How it works
Video size = bitrate × cameras × hours × days ÷ 8. Photos = number of photos × size per photo. The total is multiplied by the number of copies. The disk suggestion is the smallest common disk size with 20% free space left over.
Questions
How many GB does 1 hour of 4K video take?
At 100 Mbps, one hour of video is 45 GB. At 150 Mbps it is about 67.5 GB, and at 50 Mbps (typical 1080p) it is 22.5 GB.
Why keep two copies?
A hard disk can fail without warning. Keeping the original plus at least one backup on a different disk protects the client's footage until delivery.
Why does the suggested disk have extra space?
The suggestion adds 20% free space for project files, renders and exports, and so the disk is not filled to the top.
Where do I find my camera bitrate?
It is shown in the recording format or quality menu, for example "XAVC S 4K 100M" means about 100 Mbps.
