How to Use This Calculator
- Enter Real-Time Duration — how many hours or minutes the event actually lasts.
- Set Playback Duration in seconds — how long you want the final clip to run.
- Input Playback FPS (typically 24 or 30) to define total frame count needed.
- Shoot Interval (sec) is how often your camera should fire a frame during the event.
- Total Frames confirms you will have enough images for a smooth playback.
- Est. Storage (GB) helps you choose a memory card with sufficient capacity.
How the result changes with Output Length
| Output Length | Shoot Interval |
|---|---|
| 61 | 4.92 sec |
| 211 | 1.42 sec |
| 390 | 0.77 sec |
| 540 | 0.56 sec |
What each input means
- Event Duration
- Real-world duration of the event to capture.
- Output Length
- Desired length of the final time-lapse video.
- Output Frame Rate
- Playback frame rate of the final video.
