Depends on the resolution of your screen. My main screen resolution is 1920 x 1200 but, my secondary is 1920 x 1080 so I end up making 2 themes based off those sizes.
Well a simple video of that nature could be quite small, but I’m sure there is a line of code someone could figure out that would allow it to fade in and out of a few different screens, that would actually be sweet. Even a code to adjust the length the splash screen would be up would be nice as well.
