Camera Memory Card Footage Capacity Calculator

How to use this calculator

1. Start by confirming the unit and value of card capacity (gb, decimal).
2. Enter recording bitrate (mbps) using compatible units. Do not enter formatted numbers with commas.
3. Review the calculated minutes figure, then compare the assumption and limitations against your scenario.

Formula used for camera memory card footage capacity calculator

Recording minutes = card GB × 8,000 ÷ bitrate Mbps ÷ 60.

• The calculator uses only the entered quantities and applies this defined relationship to report minutes. It does not collect personal information or fetch remote measurements.
• To reproduce a result, use the same input values, precision and units. The default example demonstrates the arithmetic, not a recommended target. File-system reserves, audio and variable-rate encoding decrease practical capacity.

Worked examples

Understanding the result

With the example inputs, the formula gives approximately 170.6667 minutes. This is a modeled quantity rather than a verified real-world outcome.

File-system reserves, audio and variable-rate encoding decrease practical capacity.

Important notes

File-system reserves, audio and variable-rate encoding decrease practical capacity.

This output is only as reliable as the measurements and assumptions you entered. Verify card capacity (gb, decimal) and all units against the relevant product datasheet, project plan, instrument reading or official requirements.
