For instance, using time lapse to reduce a sunrise (or sunset) to a few seconds versus minutes can add a compelling effect to your videos. It works exceptionally well for extremely long clips to make time go by quickly. As opposed to adding frames, with time lapse a video editing software will remove frames per second to create the effect of faster action in a clip.
This is traditionally done by capturing frames at a much slower rate and playing them back at a faster rate. In contrast, a time lapse aims to drastically reduce the time during a video clip. This will make a clip’s playback time longer. This is achieved in a video editing program that generates extra frames in the video to create the effect of slowing down the action in the clip. This can also be achieved by slowing down a video clip to play back at a reduced speed. When replaying back at normal speed, time appears to be moving more slowly. This is traditionally achieved by capturing frames at a rate much faster than it will be played back.
If you aren’t familiar with slow motion, it’s simply the effect in which time appears to be slowed down in a video. Slow Motion & Time Lapse Video What is Slow Motion?
