CamStudio is the best free screen recorder, but it lacks one feature that many people wish was included, zoom. I've seen several videos trying to find the solution to this problem. Some people are getting a small magnifying glass program, others are using Ctrl-Z on their computer keyboard. There is even a video showing how to get zoom & pan by running two separate CamStudios at the same time. All this is unnecessary. I've found a great piece of freeware that will zoom and pan your screen for recording with CamStudio. This free software also has extra features like draw, and it even has a timer to set for taking breaks. You can set it's alarm to let you know when your break is over & it's time to get back to work.
This nifty freeware is is called Zoom It. It was written by Microsoft for people who do presentations. In this video I will demonstrate it and show you how you can get it.
