Another big advantage of the "embedding tool" is that it works kind of like a template. If you ever want to change the video, then you change only the single "video page", and every page that use the video are automatically updated to display the new video. This makes management and change tracking much more easy. This is perfect if you ever want to "update" a video. This is what Hero did to update his videos without touching the pages directly (although he did also use this functionality to replace other users videos with his own).

This also means you can protect individual videos, without necessarily protecting the pages they are on.

Furthermore, it also allows users to make wiki-comments/discussions directly on the video page, and not youtube. This allows wikia users to directly react to the video's usage relative to the current wiki. As a matter of fact, you can even create a video page before any video is actually attached, and discuss which video you think would be best before hosting it.

Regardless of actual hosting or not, your current Terraria Wiki:Image policy can also be applied to videos no? Mainspace videos should be "hosted", the others, simply linked.

I hope I actually said things you didn't know, and that it helped.
