What this tool does
Calculate time-lapse interval from technical measurements. Evenly spaced shots across duration; exposure time must fit within interval.
How to use the Time-Lapse Interval Calculator
- Enter or select event duration (minutes).
- Enter or select target clip length (seconds).
- Enter or select playback frame rate.
- Read the calculated result; change any measurement to compare alternatives.
Formula
frames=ceil(clip seconds×FPS); interval=event seconds/frames
- duration
- Event duration (minutes)
- clip
- Target clip length (seconds)
- fps
- Playback frame rate
Evenly spaced shots across duration; exposure time must fit within interval.
Worked example
For time-lapse interval calculator, the following measurements illustrate the exact method: Event duration (minutes): 60; Target clip length (seconds): 20; Playback frame rate: 30.
Inputs
- Event duration (minutes)60
- Target clip length (seconds)20
- Playback frame rate30
Result
- Interval between shots (seconds)6
- Total shots600
Results explained
- Interval between shots (seconds)
- Interval between shots (seconds) from the formula above. Evenly spaced shots across duration; exposure time must fit within interval.
- Total shots
- Total shots from the formula above. Evenly spaced shots across duration; exposure time must fit within interval.
