You could have downloaded VideoUpLink 1.6.3 for Mac from our software library for free. The application lies within Audio & Video Tools, more precisely Players. This Mac app is an intellectual property of Mark Morris.
From the developer:
VideoUpLink provides a drag-and-drop interface for uploading one or more videos to any Facebook page. Video files can be dragged from an iPhoto library, the Media Browser, or from the Finder anywhere on your drive. A title and description for each video can be added using the table view. Login to Facebook with the Login button, and then click Upload. An accurate progress bar will appear for each video as it is processed.
