The animated short film Sensual explores a novel workflow for hand-painted watercolor animation, blending traditional artistic methods with AI-based frame interpolation techniques. This paper highlights the advantages and disadvantages of different methods for interpolating 2D animation and proposes a new workflow developed during the production of the film. By combining traditional compositing tools with image interpolation using the Real-Time Intermediate Flow Estimation (RIFE) network, the approach significantly reduced production time while maintaining the unique hand-painted aesthetic. The presented work does not conflict with moral or ethical issues of AI technology and serves as a blueprint for enabling artists to fulfill their vision more effectively.
