What Does a Time Lapse Calculator Do?

A time lapse calculator estimates how much real-world time your finished clip represents. Give it a shooting interval, clip length, and playback frame rate, and it tells you how long the camera was capturing the scene.

How Real Time Is Calculated

Multiply the number of frames in your clip by the seconds between each photo. Frame count equals clip duration times playback fps.

For example, a 30 second clip at 30 fps with a 5 second interval covers 75 minutes of real time.

Frequently Asked Questions

What is a shooting interval?

It is the wait time between captured frames. A 5 second interval means the camera takes one photo every five seconds.

How many frames are in my clip?

Multiply clip duration in seconds by playback fps. A 30 second clip at 30 fps contains 900 frames.

What is compression ratio?

It compares real time covered to final clip length. A 75 minute event compressed into 30 seconds is a 150:1 ratio.

Does shooting duration include the last frame?

Shooting duration here counts intervals between frames. With N frames there are N minus 1 gaps between exposures.

Which playback fps should I use?

Match your export setting, commonly 24, 25, or 30 fps. The frame rate changes how many stills fit into the same clip length.
