Work out time lapse clip length instantly with clear inputs, formula shown and shareable results.
Clip length is frames divided by playback frame rate, shooting time is frames times the interval, and the ratio of the two is the speed-up factor. A ten second clip at 24 fps needs 240 frames, which at a five second interval takes twenty minutes to capture, so interval choice dominates the shoot plan.
Clip length
seconds = frames / playback fps
Speed-up
factor = frames x interval / clip length
seconds = frames / playback fps. Clip length is frames divided by playback frame rate, shooting time is frames times the interval, and the ratio of the two is the speed-up factor.
A ten second clip at 24 fps needs 240 frames, which at a five second interval takes twenty minutes to capture, so interval choice dominates the shoot plan.
Enter number of frames, playback frame rate, interval between shots. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
