About this calculator

The Time-lapse Calculator helps you plan fast-motion videos. You enter the total recording duration (in hours or minutes) and the interval between each photo (in seconds). The tool calculates how many photos will be taken and, based on the desired frames per second (fps), determines the final video length. For example, a 2-hour recording with a 5-second interval at 30 fps yields 1440 frames and a 48-second video.

The calculation is straightforward: divide the total recording time (in seconds) by the interval to get the number of frames. Then divide that number by the chosen fps to find the video duration. This calculator is useful for photographers, filmmakers, and hobbyists creating time-lapses of sunsets, construction, crowds, or natural phenomena. It prevents planning errors and ensures you have enough battery and storage space.

Important considerations: the interval must match the scene's motion (shorter intervals for fast action, longer for slow clouds). Standard fps of 24 or 30 is common, but lower values (like 15) can save space. Remember that the camera needs to be stable and have extra battery. The calculator assumes no pauses; if there are breaks, the result is approximate. Always check your memory card capacity before starting.

Frequently asked questions

What is the ideal interval for a cloud time-lapse?

For slow clouds, use 10 to 30 seconds. For fast clouds or storms, 2 to 5 seconds.

How many fps should I use for smooth video?

30 fps is standard for smoothness. 24 fps gives a cinematic look, and 15 fps saves storage.

How do I calculate memory card space?

Multiply the number of frames by the average photo size (e.g., 5 MB per RAW photo). Use the calculator to know how many photos will be taken.

Can I use the calculator for phone time-lapses?

Yes, as long as your app allows setting interval and fps. The calculation is the same.

What if the battery runs out before the end?

Reduce the total duration or increase the interval. Use an external battery or power bank.
