Star Guardian 2017 Dynamic Wallpaper

I'm sure that I'm not the only one who sees the login screens and thought that they would look awesome as an animated background. Though I do have to say that the New Horizon theme was good enough to encourage me to do something about it; however, since the Alpha client released I've been unable to find the .flv files used for the login screens, and I've haven't been able to get the right quality by converting the youtube video.

I was wondering if someone knew how to find the login screen file or if a Rioter would be so kind as to let me use that file so i can share the awesomeness with everyone? Preferably in 1920x1080 if that is available. Thanks for any help! [slayer-pantheon-thumbs]
