Abstract The paper explores the interaction of 2D and 3D animation in modern motion design, analyzes their functional and visual features, identifies the advantages and limitations of each approach, and justifies the feasibility of combining them. It is established that the synergy of two-dimensional and three-dimensional animation provides a balance between production speed and visual expressiveness, increasing the effectiveness of visual communication. Practical aspects of the application of combined solutions in various areas of digital design are considered.
