Also, the more frequent photos you take, the smoother your timelapse will be. So depending on what you are filming, if you want a smooth video of the sun rising and setting, you would want to adjust your photos so that they match this setting (24 frames / 1 second = 1/24th of a second per frame, or a length of. Generally speaking, most videos are shot at at least 24 frames per second.
It would be pretty boring to watch this happen all in one go (maybe not that boring, but it would definitely take a while!), so making a timelapse is a cool way to showcase a longer event in a shorter period of time. You have probably seen tons of timelapses of the sun and clouds moving across the sky. Great question! A timelapse is a filming technique that takes an action (in my case, a 3D printer) that can take a long time, records it, and plays it back in high speed.
