Time-Lapse Calculator

About this calculator

This calculator turns your shooting plan into a finished clip length: total frames captured = shooting duration ÷ interval between shots, and finished clip length = total frames ÷ playback frame rate — so shooting for 2 hours at a 10-second interval and playing back at 30 fps yields 720 frames, a 24-second clip.

Photographers and filmmakers use it before pressing record to choose an interval that gives smooth motion at the intended playback speed and a clip length that fits the project, whether that's a slow cloudscape shot over many hours, a construction project tracked over months, or a fast-motion plant-growth sequence shot over days — getting the interval wrong means either a jerky result or thousands of unnecessary frames to sort through.
