Time Lapse Calculator

Plan how long to shoot and how many frames a time-lapse needs.

How the Math Works

The Time Lapse Calculator uses two simple but powerful formulas to determine your project's requirements. First, frames = clip * fps calculates the total number of individual photographs needed by multiplying the desired clip length (in seconds) by the frames per second rate. Then, time = frames * interval determines the total shooting duration by multiplying the frame count by the interval (the time between each shot). For example, a 10-second clip at 30fps requires 300 frames, and shooting at 5-second intervals means you'll need 1500 seconds (25 minutes) of active shooting time.

Practical Applications

To use this calculator practically, start by deciding your final clip length and target frame rate - common video standards are 24, 25, or 30fps. Next, determine your interval based on the motion speed you want to capture: 1-3 seconds for dramatic cloud movement, 5-10 seconds for plant growth, or 30+ seconds for slow geological changes. Input these values to instantly see how many photos you need and how long your shooting session will take, allowing you to plan battery life, memory card capacity, and optimal shooting times.

Day-to-Day Use

This calculator transforms abstract time-lapse planning into concrete, manageable steps that prevent wasted effort and missed opportunities. Whether you're documenting a sunset, tracking seed germination, or capturing city traffic patterns, you can confidently answer 'How long do I need to be there?' before setting up your camera. It also helps you understand creative trade-offs: faster intervals create smoother playback but require more storage, while longer intervals compress hours into seconds but may miss important moments. This knowledge turns guesswork into deliberate artistic choice.

Worked example

A 20 s clip at 24 fps with a 5 s interval needs 480 frames over 40 minutes.
