Watch this short prototype video and provide feedback

The video is well recored, and from it I can understand how it works. However, if you are going to share it, I would add some voice over. Perhaps set some expectations at the start , saying something : "In this videos I am going to upload 3 different files, and show how to capture and clean up the data" , and then , in the process describe what are you doing.
