The video shows a close-up of a cake decorator's hand as they use a piping bag to apply icing onto a cake. The cake is round and covered in white icing. The decorator is creating a tree trunk on the side of the cake using brown icing. They are also adding green leaves and red berries to the tree, using a different color of icing for each. The leaves are shaped like real leaves and the berries are small and round. The decorator's movements are precise and careful, ensuring that the tree trunk and decorations are evenly spaced and symmetrical.
