{{Module|name=mosaic|type=Video subfilter|first_version=0.8.2|description=blend sub-videos on a video}}

Use this filter to blend videos on top of another video. This can be used to create TV channels mosaics, setup a weather channel like stream (with the [[Documentation:Modules/bluescreen|bluescreen]] video filter) and lots of other fun stuff.

Since VLC 0.8.6, you can also use the [[Documentation:Modules/http_intf|HTTP interface]]'s mosaic wizard to configure a mosaic easily.
