I will teach you how to set a video as a wallpaper!
1.Get VLC media player. You should have this already, if not, get it.
2. Go to Video > Set as wallpaper

And boom, you should have the video as a wallpaper.

The wallpaper looks like shit? Get a higher res video if necessary.
There’s a gap between the video and your taskbar/edge of the screen?

Closing down VLC and re-loading the video will make the video bigger again, but keep in mind, that you will need to redo everything. Getting a video that is the same resolution as your screen won’t make this happen.
That’s all, hope you enjoy your counter-productive wallpaper!
