Abstract: Editor’s notes: This article introduces a dedicated hardware solution that integrates optical-flow-based prediction refinement into the VVC affine motion estimation process. The architecture can deliver real-time performance for 4K UHD video.—Ney Calazans, Federal University of Santa Catarina (UFSC), Brazil—Bruno Zatt, Federal University of Pelotas (UFPel), Brazil
