BackDrop_

BackDrop_ plays any local video as a transparent ghost overlay on your desktop — always visible, never in the way. Built for developers, students, and anyone who wants a floating video companion while they work. Unlike Picture-in-Picture, it works with your own local files (MP4, MKV, AVI, WebM and more) and never steals window focus. Live effects, custom hotkeys, and a 10-language interface.
