A quick and simple time-lapse calculator with three modes. The default mode allows you to determine the shutter interval (time between shots) that is required to achieve a desired video clip length for a given recording duration.
Most time-lapse utilities only allow you to enter the recording duration and shutter interval. Then they calculate the duration of the video clip that would result. That is occasionally useful, but most of the time it’s backwards.
If you know how long you would like the final clip to be, your video frame rate, and how long you plan to continue capturing exposures to cover the event, then it is the interval variable that you need to calculate.
The Time-lapse Calculator can also be set to calculate the target duration (video clip length) or event duration (recording time) based on the other variables.
In addition to the intervalometer functions, the Time-lapse Calculator estimates the memory card storage capacity that will be required for RAW or high-quality JPG image files, based on the megapixel count of your camera.

Time-lapse video: New York City Marathon (2014)
4K (Ultra HD) time-lapse video of runners racing through Brooklyn during the New York City Marathon on Sunday, November 2, 2014. Two cameras capture the entire day into night (as viewed from my balcony).
I used my Time-lapse Calculator app to determine the optimal shutter interval and memory card requirements for 12 hours of shooting.
