QQ2009 Preview 3 (Audio and Video Optimization Edition) is currently in hot trial use.

After a whole year of research and development, the QQ audio-video team has now updated the latest core to Super Voice and Super Video. The new version features a new video codec, optimized bandwidth and error correction algorithms, adjusted anti-packet-loss strategy, and re-supports one-to-many video chat. There are obvious improvements in connection speed, voice continuity, call quality and other aspects. This version embodies the technical achievements of our audio-video team over the past year, and is our Mid-Autumn Festival gift to you. So what are you waiting for? Try it now!
