Data Calculator

Pick a camera, sensor mode, codec and frame rate to see how long a card records and how many you need.

Format

Capped to what this sensor mode can shoot.
Only converts screen time to record time — the data rate always bills at the sensor rate.

Media & shoot

Filtered to media this camera records to.
Optional — shows the total runtime the set you already own buys.
Blank uses the per-interface default: 96% Codex, 85% CFexpress Type A, 94% Type B, 97% otherwise.

= 8 h

Splits the total into a per-day figure — the hours above stay the whole shoot.
Destinations the footage is written to — working drive, shuttle, LTO.

Audio

Added as a flat bitrate, not a percentage — negligible on RAW, but around a tenth of a ProRes Proxy stream.
