While reflecting on the second video, I found the sound in the video to be very interesting. So in the third experiment, I tried to extract the sound from the video.

At first, I wanted to find some prominent points in the sound and then enlarge it as much as possible.

At the same time, I also tried to speed up and slow down the two processing methods, however, as I was not familiar with the sound control software, the end result was bad.

Based on this, I watched the video again and tried to discover some details that I hadn’t noticed before.

 

I realized I might not be destroying the original picture with a punch.

 

So I reversed the video and added sound to it, and the whole process turned into a picture I was using a punch to repair.
