How is time-lapse photography made and how is it made into a video?

Screenshot, just take a box you want and it will become a picture.

Time-lapse photography, also known as time-lapse photography and time-lapse video recording, is a shooting technique that compresses time. Generally, a group of photos are taken, and then the process of several minutes, hours or even days is compressed into a short time by concatenating the photos into a video, which is played as a video.

In time-lapse photography video, the slow change process of an object or scene is compressed into a very short time, showing a strange and wonderful scene that is usually imperceptible to the naked eye.

Time-lapse photography can be regarded as the opposite of high-speed photography. Time-lapse photography is usually used to shoot urban scenery, natural scenery, astronomical phenomena, urban life, architectural manufacturing, biological evolution and other topics.

Shooting method:

The process of shooting time-lapse photography by machine is similar to making a freeze frame. A number of pictures with the same shooting interval are connected in series to form a dynamic video, and the low-speed changing process of the scene is shown with obvious changing images. For example, it takes about 3 days and 3 nights for a bud to bloom, which is 72 hours.

Take a picture of it every half hour, record the subtle changes of flowering action in sequence, and take 144 photos, and then connect these photos in series to form a video, which will be played at normal frequency (24 frames per second) to show the flowering process for 3 days and 3 nights in 6 seconds.
