Mind Blown! I watched the "video" and was like of this is great and the option to upload to a website not youtube made me go Meh. Then I read the following line.

You can copy and paste from the "video!" So when I give someone a tutorial on a command line tool they can copy and paste the codes themselves!
EDIT:
People can use the recording to show what they are doing to give them the error and display the output!
