Google news for all of you who use Gmail video chat. Cool New lab feature will help you to preview video features before it is on for everyone. Visit Gmal Labs tab under setting and turn on the "Video chat enhancements". You will see a higher resolution and bigger video chat Window.
"The higher resolution video uses a new playback mechanism which enables widescreen VGA and frees up valuable resources on your computer. For it to work, both you and the person you're chatting with will need to have the lab turned on. Remember that you can always revert to standard video chat by disabling the lab." Says in Gmail Blog.
