Wikia supports embedding videos from a variety of sources, which are listed below. Please note that videos embedded from YouTube may not have been uploaded with proper licensing and permission, and could potentially be removed from YouTube at any time. By embedding videos from the Wikia Video Library you can be confident that the clip is properly licensed for use on your wiki, through one of our partners.
Videos can be embedded in your article page, added to an infobox or added into a gallery or slider. Wikia also offers features that help to visitors find interesting videos on your wiki.
The Videos Module is another feature that helps to surface video on your wiki for readers and contributors, by suggesting videos in the right rail. Videos can also be added to a wiki using the button in this module.
Special Videos page
All of the videos currently available on a wiki can be seen on the page Special:Videos, which is linked from the "On the Wiki" navigation tab. New videos can be added to the wiki using the button at the top of that page, or by using the Video Embed Tool when creating or editing a page.
Special Unused Videos page
Videos that have been added to the wiki but are not used on any pages are listed on Special:UnusedVideos.
We track all video views and display them on the video thumbnail. This number is based off of how many times someone has clicked the thumbnail to watch the video and when the video has been played on a file page. This number is tracked internally by Wikia and may differ from how other providers track their video views.
Here are some pages on various wikis where video has been incorporated in interesting ways:
