Slow motion seems to elongate time. In a normal video, we are just watching more frames in the same amount of time. When the frame rates are changed, time seems to slow down. "The One Moment" music video took about 4 seconds to film, but the slow-motion video is 4 minutes long.

For example, if we have a 1 second video at 120 fps and slow it down to 30 fps, the resulting video would take 4 seconds.

Example:

X seconds = 120 frames

Then

x= 4 seconds

OR

1 second = 30 fps

Your turn: Try the following two problems below:

1. If all of the ball crashes occur in 15 seconds in the slow-motion rate of 30 fps, how long would the video of ball crashes be at the recording rate of 550 fps?

1. What if we filmed another phone video of you jumping for 6 seconds? If we filmed at a recording rate of 240 fps and slowed down the film by changing it to a slow-motion rate of 24 fps, how many seconds would you be jumping in slow motion?
