A time-lapse video is a sequence of photographs taken from the same point at regular intervals which, played back one after another, condense a process lasting hours, months or years into seconds. It is the technique that lets you watch a building rise, a stage go up or a whole day in a city go by in under a minute.
At Droneit the standard frequency is one photo every 5 minutes. A full 24-hour day comes to 288 photos, or about 11.5 seconds of video at 25 frames per second.
If you need one, take a look at our time-lapse service or, for a construction site, our construction time-lapse with 24/7 monitoring.
You have almost certainly seen a video that, from a single viewpoint and in just a few seconds, sums up what happened over a few hours, a day, a month or even years. What you saw is called a time-lapse.
It is simply a photographic technique for capturing, through still images, events that normally unfold very slowly. This lets us show a situation in far less time than it really took. In practice, a time-lapse video lasting 1 to 3 minutes can capture how a process evolved over several weeks, months or even years.
WHY PHOTOS RATHER THAN VIDEO?
There are two reasons:
1. Quality: video quality is always much lower than photo quality, and speeding up a video loses even more.
2. Size: however many images there are, they take up less space than a video covering the same period of time.
WHAT IS A TIME-LAPSE VIDEO USED FOR?
You can make a time-lapse video of anything you can think of. Broadly speaking, there are 3 main types of situation:
1. Landscapes: sunsets and sunrises, clouds, traffic in a street, and so on.
2. Nature: a flower blooming, the time it takes a bird to hatch from its egg, and so on.
3. Others: the construction of a building, movement in a city, or construction progress monitoring on projects such as a football stadium, an industrial building, a factory or a housing development.
The time-lapse technique is used by many media outlets, agencies and photographers. Its purpose is to show long-running events in a short video. The work can be artistic or technical. In truth, though, you can use the technique anywhere the passage of time can be seen.
As a company specialising in construction progress monitoring, Droneit offers services that adapt to every client's needs. If you need to promote a new property, carry out geometric control of works or track a construction project through to completion, get in touch with us.
