If you have multiple logbooks in your account, you can also move videos from one logbook to another.
In order to do this, you need to select the video you want to move.
When you click on your video, you'll load it into the viewing pane.
Towards the right of the video window, there are a vertical set of icons which are menu options. The COG icon is the options and clicking here will present the options to move the video to another logbook.
Simply select another logbook from the drop down list and your video will be moved.
