Smart H.265+ Smart H.265+ is the optimized implementation of H.265 codec that uses scene-adaptive coding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ greatly reduces bit rate and storage requirements compared to standard H.265 compression. |
