How to add motion blur in timelapse videos? I remember watching a video about timelapse photography. There was a moment when the narrator explained that there is a specific trick to make the videos "smoother":


In the timelapse videos which don't use this trick, if people are moving, they suddenly appear at a precise frame, then disappear,
In the videos which use the trick, we have a feeling that they are smoothly moving, like if there was a motion blur.


What is this technique? What is it called? Is it done when taking photos or during post-processing?
One solution to the jerkiness of stop-motion animation was developed for some Star Wars sequences, termed "Go Motion".

Basically the idea is that you leave the shutter open a little longer than necessary, and move the objects a bit, to create some motion blur.
