How to set it on your phone
iPhone · moving
Live wallpaper
Save the MP4 to your phone.
Open it in a free app like intoLive and export as a Live Photo.
Settings → Wallpaper → Add New → Live Photo → pick it.
On the lock screen, press and hold to keep the motion on.
Android · moving
Video wallpaper
Save the MP4 to your phone.
Install a Video Live Wallpaper app (Play Store).
Open it, choose the MP4, fit to screen.
Set as wallpaper — lock, home, or both.
Any phone · still
Static wallpaper
Download the PNG.
Open it in Photos and tap Share / the … menu.
Choose Use as Wallpaper.
Position and set. Done.
Tip: on iPhone, saving a raw video as your wallpaper needs the one-time Live Photo step above — iOS doesn’t accept a plain video file directly. Android sets the MP4 straight through a live-wallpaper app.
