H 263 Video Sample [upd] Download Better Review

Designed as an improvement over its predecessor H.261, H.263 introduced several key innovations: half-pixel motion compensation, unrestricted motion vectors, and advanced prediction modes. These enhancements allowed it to achieve roughly half the bitrate of H.261 for the same visual quality. At typical target bitrates of 20–50 kbps for QCIF (176×144) resolution, H.263 made real-time video feasible over 28.8 kbps modems and early ISDN lines.
