24 FPS = 1440 frames per minute
One minute of final video at 24 FPS needs 1,440 photos. A 10-second clip needs 240.
Total elapsed time the camera will observe.
One photo per frame for a smooth sequence.
Tip: Match shutter to roughly half the interval (180 degree rule) for natural blur, especially with ND filters outdoors.
One minute of final video at 24 FPS needs 1,440 photos. A 10-second clip needs 240.
Clouds at sunset can change 10 to 50 times faster visually than midday scenes—tighten intervals as light shifts.
Long gaps still add up: a 4-hour shoot at a 10-second interval fires 1,440 shots—pack spare batteries or external power.
A perfectly spaced interval beats higher resolution when motion is fast. Miss the cadence and the clip feels jerky.
Moving the camera between shots turns it into a hyperlapse—interval math still drives smoothness.
This calculator removes guesswork before you set up. Enter the scene duration, final clip length, and playback FPS to see the required interval, total frames, and slack time from rounding. The math is simple: total frames = length x FPS, interval = scene duration / total frames.
It runs entirely in your browser so you can use it offline on location. The warning callout flags sub-second intervals that may outrun camera buffers or SD cards. Use the output to pick ND strength and shutter times that keep a natural blur while staying within your camera’s limits.
Test your plan by firing a short burst at the chosen interval and reviewing buffer clearance. If shooting sunrise or sunset, start with this interval and adjust gradually as light changes to prevent flicker.
