After searching a bit on the Internet, here is what I came up with: http://camstudio.org/
It can create videos from your screen and generate swf to easily enter them on websites.
He is able to add beautiful, smooth text on the screen to the video and even supports video in picture (text on the screen + video about you through a webcam)
You can record the entire screen or just part of it. I'm not sure if it supports zooming in subzones when rewriting in real time, but even if it isnβt, itβs easy to emulate it using Windows 7 scaling (or if you are not using Win7 with tools like ZoomIt from Sysinternals
It also has its own free codec.
All 100% free, open source and licensed under the GPL, woo !!: D
PS I am in no way connected with them. I just found it myself :)
