The 20 second mark is the standard WP Toolbar.
If you have just one bar click on the “show hide / kitchen sink” icon – 2nd from the right side, (has 3 lines of real little boxes that are different colors) That should show / hide the 2nd bar.
Um I do not have that icon for my wordpress edit. On the visual tab I only have the upload/insert button and on the html it is the previous toolbar layout named in my last post. I do not see the 3 lines of real little boxes that are different colors
