4K Storage
How Much Storage Do I Need for 1 Hour of 4K?
At 100 Mbps, one hour of 4K video uses about 45–50 GB; higher bitrates and frame rates increase storage needs proportionally.
Estimate by bitrate, not just resolution
To size cards, take your camera's bitrate in Mbps, divide by 8 to get MB/s, then multiply by 3,600 for one hour. Add 10–20% headroom for metadata and filesystem overhead. Higher frame rates or All‑I codecs raise the bitrate, so always check the recording mode details.
