Video capture

What is video capture and what does it do? Thx
Hi:

General meaning: Video Capture is like taking a video of what is on your screen. Free programs like Microsoft Expressions can video capture allowing users to upload videos of their games.

ZunTzu meaning: While playing an online game with ZunTzu, a video/voice link is established between the two computers - a cool feature I have not tried :-{

I hope this helps,

Regards, Rich
