As said in the video, several hundred city driving miles is best before letting it hang for the first time. If your clutch starts off smooth on your first drive, chances are better than not it will only start to vibrate / chatter if you don't follow the correct procedure. Be sure to pull away normal (easy for those that normally drive aggressive all the time) making sure to not slip the clutch anymore than absolutely necessary. Heat is a new clutches worst enemy.
Hope this helps.
