Video Storage Calculator — From a Known Bitrate

It depends on bitrate and recording time. At 100 Mbps, one hour of recording uses about 44 GB. A typical 8-hour wedding with 3 hours of recording needs about 132 GB. Always bring at least 50% more storage than calculated.

Event/wedding: 25-50% recording time. Documentary: 50-80%. Interview: 60-90%. Music video: 20-40%. Corporate: 30-50%. The recording percentage helps plan storage without overestimating.

Multiple cards reduce risk — a failed card loses only part of the shoot. For events, switch cards at natural breaks (ceremony, speeches, reception). For interviews and continuous recording, larger cards avoid interruptions.

4K at the same quality requires roughly 4x the bitrate of 1080p. A typical 1080p shoot at 28 Mbps uses ~12.3 GB/hour. The same content at 4K might use 100 Mbps = ~44 GB/hour. H.265 codec reduces this by about 30-50%.
