cD =
Number of days (with or without a decimal) that will be captured by the time lapse period.
cH =
Number of hours (with or without a decimal) that will be captured by the time lapse period.
cM =
Number of minutes (with or without a decimal) that will be captured by the time lapse period.
cS =
Number of seconds (with or without a decimal) that will be captured by the time lapse period.
tH =
Number of hours (with or without a decimal) for the output duration of the time-lapse video (play length).
tM =
Number of minutes (with or without a decimal) for the output duration of the time-lapse video (play length).
tS =
Number of seconds (with or without a decimal) for the output duration of the time-lapse video.
P =
Number of frames per second (with or without a decimal) in the final output video.
S =
Number of seconds between frames to set on your camera to capture the input amount of time and compress it to the output amount of time given the output frame rate.
Choose the number of decimals to show in your answer. This is also known as significant figures. Select an appropriate amount of significant figures based on the precision of the input numbers.
Given the desired amount of time to be captured, the desired target of the final video clip, and the frame rate of the video clip, how frequently should the camera capture a frame?
TOTAL CAPTURE LENGTH / (TOTAL TARGET DURATION * FRAME RATE)
When capture length and target duration are given in seconds this formula will given the number of seconds that should elapse between capturing each frame.
The inputs required for this calculation are only three: desired length of time to capture, target length of final video, and frame rate of final video. To simplify the calculation time may be input in days, hours, minutes and seconds but all are converted to seconds for the calculation. Frame rate must be known in advance and is a consideration of how the final video will be published, some common frame rates are given below for reference.
