WHAT IS THE DURATION OF A TIME LAPSE?
When speaking about time lapse, one frame equals one photograph.
Therefore, for a video of only 10 seconds, 250 photographs will be needed. A one minute time lapse video requires 1,500 shots. For an event that lasts 1 hour (for example a sunrise) or 3600 seconds, to capture it in a 30-second video at 24fps (720 photographs), the interval must be 5 seconds. This is regardless of how the movement in the frame will actually evolve. For an event that does not have a well-defined duration, it is instead necessary to adjust the shutter frequency based on the speed of the subjects: the shutter frequency of people in movement will therefore be different from that which will capture vehicles moving on a road (which should be faster).
