In the video, a person is seen brushing a cake with a red brush. The cake is placed on a white plate, and the person is wearing a white glove on their right hand. The brush is being used to apply a liquid, possibly oil or syrup, onto the top of the cake. The person is moving the brush in circular motions, ensuring that the liquid is evenly distributed across the surface of the cake. The cake itself appears to be a light brown color, suggesting it may be a sponge or pound cake. The background is a plain white surface, which puts the focus on the cake and the brushing process.
