Time Lapse Photography Calculations
Below are 3 "calculators" to help those answer common mathematical questions for time lapse work. Determine the question you need answered, plug in your "input" values, press the button for the answer
Time Compression:
Playback Duration:
Constrained Playback:
What interval should I use to compress my event time down to a specific playback time?
I shot an event at a set interval. How long will my video playback be?
I want a video of a certain length, shot at a given interval. How long of an event will I have to shoot?
Terms Glossary:
Event
The duration you are shooting, expressed in minutes in these calculators. A long event could be many hours (6 hours = 240 minutes)
Playback
The length of the final video plays back. Expressed here in terms of seconds.
Interval
The time between shutter releases, expressed in seconds in these calculators. Since most intervalometers (aka timers) don't
do sub-second intervals, intervals here are rounded to nearest second.
Frame rate
The rate at which the final video plays back. Expressed in terms of frames per second (fps). The most common values used
in video are: 24 (film), 29.97 (NTSC DVD style video), and 30 (modern video). "60i" refers to 2 interlaced frames played back at 60 frames per second, but that interlacing makes it equivalent to 30pfs.
time entry
Entering times in this calculator can be done in the format hh:mm:ss, or in whole values. For example, you can enter 90 seconds as: 90 or 1:30. They mean the same thing. An hour can be entered as 1:00:00 or as 60:00.
