Timelapse Calc provides a quick and accurate way to calculate a recommended frame interval, in seconds per frame, to use to compress a realtime duration into a timelapse duration when played back at a particular frame rate.

To calculate the recommended timelapse frame interval enter the days, hours and minutes of the period you want to record, how long the timelapse video should run for and the frame rate you plan to playback the timelapse video at. The recommended frame interval is then displayed.
