![]() ![]() This method is great when you have an idea of how long you are going to shoot. You are going to calculate the interval required to capture a certain time range for you desired length of video. Total time based calculation is the opposite of interval based. First, you need to figure out how many frames you will need: 24 frames per second x 15 seconds = 360 total frames From this you can calculate the total time you’ll need to capture 360 frames: 360 frames x 3 seconds = 1080 seconds, or 18 minutes You will need 18 minutes of shooting, using a 3-second interval, to create a 15 seconds video. Let’s say you want to create a 15-second time-lapse video, using 24 frames per second, with a 3-second interval. Once you determine your interval, you can then calculate the total time you need to shoot to create a video of your desired length. For a slow moving scene, like moon rise, use a longer interval around 20 seconds. With a fast moving scene, like a moving cloud, you need a short interval about 3 seconds. If you have a rough idea of how fast your scene is moving, you can estimate the length of your interval. From that, you can calculate how many frames you need and the total time you’ll need to shoot. With an interval based calculation, you decide the interval of frames and the length of the video first. There are two main calculation methods to determine your interval between shots and time required: interval based calculation and total time based calculation. For example, I will use a 2-5 second interval when shooting a fast moving subject like daytime cloud changes, a 10-15 second interval when shooting a longer period change like sunrise or sunset, and a 30-40 second interval when shooting slow moving subjects like stars or the Milky Way. Intervals can vary widely, depending on your subject. When shooting a time-lapse sequence, you have to decide the interval between each frame. ![]() You may want to use up to 30 frames per second, but of course you’ll need to shoot a lot more frames. It seems like a lot, but your camera can do most of the work for you. Your first task in creating a time-lapse photography video is to calculate how many frames you need for the video. Normal video is shot at 24 frames per second you need 24 photos to create 1 second of video. ![]() A time-lapse video is a compilation of a sequence of photos taken over a long period of time. You may find it overwhelming at first, but it is definitely worth learning.Įssentially, time-lapse photography is a video, or a compilation of thousands of still shots. Just like the picture flip books from your childhood, when you play a series of images within a very short time, it becomes a video. Here’s a time-lapse example from my trip to New Zealand in December 2015:Ĭompared to shooting images, time-lapse photography requires more knowledge and patience. ![]()
