If you are hoping to turn this into some kind of business or money-generating thing, it's not. You are creating very little long-term value, as the others have noted, it seems mainly an SEO play.

I do like the basic idea though, If you really wanted to make it good, you'd have to create much better navigation/browsing/finding options (that's the only value you're adding), and you'd have to seed it with 10000s of videos, and you'd have to add something, like forums or reviews something, that increases the value for users.
