✳ FREE CALCULATOR
Storage calculator
Work out how many minutes of footage fit on a card or drive at a given bitrate.
- Recording time
- 3h 3m 15s
- In minutes
- 183 min
- Per hour of footage
- 21.0 GB
- Clips of 60s that fit
- 183
Calculated as: seconds = capacity bytes × 8 ÷ (Mbps × 1,000,000)
What this assumes
- Card capacity is usually advertised in decimal GB but reported by the OS in binary GiB, so usable space is a few percent lower.
- Assumes a constant recording bitrate.
Koldflux works these numbers out for you when it exports - the calculators exist because our own pipeline needed them first.
