The video shows a close-up of a tray with several round cavities filled with a brown mixture. A person wearing a purple glove is holding a piping bag filled with a similar brown mixture and is piping it into the cavities. The brown mixture appears to be a chocolate-based filling, and the tray seems to be a chocolate mold. The person is filling each cavity carefully, ensuring that the filling is evenly distributed. The video is shot in a way that the viewer can see the filling process clearly.
