Hi Tormented,  Wikia does not host any videos, but rather allows you to embed and display them on your wiki. We do have a premium video library, video.wikia.com, that includes videos from our video partners from which we have the explicit rights to display their content (the videos are still hosted by a third party).This content will not get pulled down for copyright violation as often happens on youtube. As for the management tools, these aren't currently connected to the visual editor, but new special pages (such as Special:Unusedvideos) which are aimed at helping admin manage the content on their wikis. We will have more updates on this soon!
