From the Edit Queue, you click the edit

icon,
the one on the left. The video’s edit window pops up. Look over and, if
necessary, improve all the editable information: category, title, description,
owner, producer, license, and age/education level. Also, supply your own
rating, that’s important too. See below for a bunch of suggestions about
how
to edit. It’s mainly a list of common problems that are fixed when we do
editing.
