Just in case one Windows Phone 8.1 leak isn't enough to carry you into the weekend, I've got one more for you enjoy. Best of all is that this time around, we've got some more video of the impending update in action.

A video of Windows Phone 8.1 running on a Nokia Lumia 630 has made its way online thanks to Coolxap and WPCentral. The clip shows a matte black Lumia 630 with on-screen navigation buttons and no dedicated camera button. During the video's 3-minute run time, we can see several new features that've been rumored to be coming with WP8.1, including the Action Center with quick settings toggles and an updated version of the Windows Phone Store.

While this newly-leaked video doesn't really offer much in the way of new information about Windows Phone 8.1, it's still nice to get another early peek at the update ahead of its official debut next week. Nothing about WP8.1 is official until Microsoft says it is, but so long as the rumors of Action Center, Cortana and more hold true, the update ought to be a pretty major one for the Windows Phone platform. The good news is that existing Windows Phone 8 hardware will be upgradeable to 8.1, so you folks that are currently rockin' a WP8 device can watch the video below to get a preview of the new features that (carrier-permitting) will eventually arrive on your phone.

UPDATE: A second video has been posted by Coolxap and WPCentral that shows Live Tile background support in action. The clip shows that users can choose an image from a default pack or from their Facebook, OneDrive or photo albums. Interestingly, we also get to see that the feature also supports parallax scrolling when moving up and down through the Live Tiles. Check it out in the second video below.
