 Backgrounds can be videos as well as stills. Drop an `mp4`, `m4v`, `mov`, `webm`, `mkv`, or `avi` file in the same folder and it appears alongside the images. Videos are played by the OWE wallpaper engine. It decodes the video once for all monitors and plays its sound through the default audio output, and it stops playback whenever nothing can see it. The lock screen draws the same decode, muted, through OWE. A video wallpaper still costs far more power than a still one.
 
 You can find a huge collection of cool curated backgrounds on https://github.com/dharmx/walls.
+
+Video backgrounds keep a cached still on the lock screen while playback is paused or unavailable. Animated GIFs play on the desktop and show a still frame on the lock screen.
