Memory Card Capacity
See how many photos and videos fit on a card after the video is shot.
About Memory Card Capacity
Video footage eats a slice of the card computed from minutes and bitrate, and whatever remains is expressed as photos that could still be shot. Hybrid shoots mix formats on one card, so splitting capacity between video time and remaining photo count stops the card mid-day.
Formula
Memory Card Capacity
Video GB = minutes x Mbps x 60 / 8000; remainder goes to photos
- Mbps
- Megabits per second average of the recorded video
Worked example
With the default values below, Memory Card Capacity returns Video Uses of 4.50. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Memory Card Capacity calculated?

Why does Memory Card Capacity matter?
Hybrid shoots mix formats on one card, so splitting capacity between video time and remaining photo count stops the card mid-day.
What values do I need to enter?
This calculator takes 4 inputs: Card capacity, Photo size, Video to shoot, Video bitrate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
