Your inputs
Calculation results
Formula & assumptions
Frames = round(clip seconds × FPS); interval = capture seconds/(frames−1).
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Time-Lapse Interval Planner
Find a capture interval for a desired finished clip duration.
- Enter capture duration, finished clip duration, playback rate using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Capture duration: 180 minutes Finished clip duration: 20 seconds Playback rate: 30 frames per second Target frames: 600 Capture interval · seconds: 18.03005 Actual clip · seconds: 20
Questions & answers
What does Time-Lapse Interval Planner calculate?
Find a capture interval for a desired finished clip duration.
Which units should I enter?
Capture duration uses minutes. Finished clip duration uses seconds. Playback rate uses frames per second. Convert values to these units before calculating.
Which formula does it use?
Frames = round(clip seconds × FPS); interval = capture seconds/(frames−1).
What does the included example show?
Capture duration: 180 minutes; Finished clip duration: 20 seconds; Playback rate: 30 frames per second. Result: Target frames = 600; Capture interval · seconds = 18.03005; Actual clip · seconds = 20.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
