The document summarizes improvements made to the Video Conferencing (VIC) tool to support high definition video for access grids. Key points: 1) The updated VIC tool leverages existing open source resources like FFmpeg to incorporate modern video codecs like MPEG-4 and H.264, allowing for higher quality video streaming in HD resolutions. 2) It adds features for error resilience, efficient color conversion, scaling viewing windows, and full-screen snapshots not previously supported by VIC. 3) Performance tests show the MPEG-4 codec can support 720p video at 25 frames/sec using around 1Mbps bandwidth while maintaining good quality.
