Timelapse Interval Calculator

Create stunning timelapse videos with the perfect frame rate and interval. Our timelapse interval calculator helps you determine the optimal settings for your photography or videography projects.

How to Use This Calculator

To calculate the optimal timelapse interval for your project:

Enter the total duration of your timelapse in hours, minutes, and seconds
Select the desired output duration for your final video
Click "Calculate" to see the recommended interval between shots
Review the results and adjust your camera settings accordingly

For best results, use this calculator with a camera that supports interval shooting mode. Most DSLR and mirrorless cameras have this feature.

Formula Explained

The timelapse interval is calculated using the following formula:

Interval (seconds) = (Total Duration × 3600) ÷ Number of Frames

Where:

Total Duration is the length of your timelapse in hours
Number of Frames is the desired number of frames in your final video

For example, if you want a 1-hour timelapse to play in 10 seconds, you would need 360 frames (10 seconds × 36 frames per second).

Worked Examples

Example 1: Sunrise Timelapse

You want to capture a 3-hour sunrise and create a 15-second timelapse video.

Calculation:

Total duration: 3 hours = 10,800 seconds
Desired video length: 15 seconds
Number of frames needed: 15 × 30 = 450 frames
Interval: 10,800 ÷ 450 = 24 seconds

Set your camera to take a photo every 24 seconds.

Example 2: Construction Progress

You're documenting 8 hours of construction work and want a 30-second timelapse.

Calculation:

Total duration: 8 hours = 28,800 seconds
Desired video length: 30 seconds
Number of frames needed: 30 × 30 = 900 frames
Interval: 28,800 ÷ 900 = 32 seconds

Set your camera to take a photo every 32 seconds.

Frequently Asked Questions

What is the best frame rate for timelapse videos?: Most timelapse videos use 24-30 frames per second for smooth playback. Higher frame rates (60 FPS) are better for fast-moving subjects.
How do I calculate the number of photos needed?: Multiply your desired video length (in seconds) by your frame rate. For example, a 10-second video at 30 FPS needs 300 photos.
What camera settings should I use for timelapse?: Use manual focus, fixed aperture, and disable auto-exposure. Set your camera to take photos at regular intervals using the interval timer or remote control.
How can I improve the quality of my timelapse?: Use a tripod, keep the camera steady, and avoid moving the subject. For night timelapses, use a remote shutter release to prevent camera shake.
What software do I need to create a timelapse video?: Most cameras have built-in timelapse software. Popular third-party options include Adobe Premiere Pro, Final Cut Pro, and iMovie.
