Why does reducing the exposure frequency induce motion blurring, despite both videos playing at the same frame rate?

Here the 1/60 is how long the exposure time is for each frame, or the period of real time that the frame samples. If the frame samples for a very short time period like 1/4000 second, then it is basically capturing the exact position of every water droplet in the scene at that point in time, resulting in time aliasing that we see in the previous slide. If the exposure time is longer, then fast objects like the droplets will have time to move slightly during this exposure time, resulting in the motion blur on this slide.
