ClarityHow to use this tool
- Enter total capture time in minutes.
- Enter the interval between frames in seconds and the final playback rate in fps.
- Calculate the number of complete capture intervals and resulting playback duration.
Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Capture duration | Numeric value. Unit: minutes. Must be greater than zero. | 60 |
| Interval between frames | Numeric value. Unit: seconds. Must be greater than zero. | 5 |
| Playback frame rate | Numeric value. Unit: fps. Must be greater than zero. | 30 |
Result for these sample inputs
24 seconds
- Frames
- 720
- Capture duration (s)
- 3600
- Unused capture remainder (s)
- 0
- Playback duration (minutes)
- 0.4
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Frames = floor(capture seconds/interval). Playback seconds = frames/fps.
One hour captured every 5 seconds gives 720 completed intervals. At 30 fps those 720 frames play for 24 seconds.
What to keep in mind
Counts completed capture intervals; no extra frame at time zero. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.
Common questions
Does this count a frame at time zero?
No. It counts completed intervals. If your camera includes an initial frame, its count can be one frame higher.
Why can a short capture give zero frames?
If total capture time is shorter than one interval, there are no complete intervals under this convention.
