Hi there and welcome to the User Forums!
What you are looking for is a full-motion video recording.
Captivate 2 has full-motion available, but the product is designed
to use it for only brief periods - for capturing such things as
grabbing a scroll elevator, or a drag-n-drop of a file object. It
is definitely not designed for on-going, continuous video capture.
If you upgrade to Captivate 3 you will find expanded full-motion
capabilities.
Other alternatives include the use of software designed
specifically for creating AVI videos. One popular software package
for this is Camtasia, but there are hundreds available out there -
just "Google" for a string like "
create video".
Having said that, if you use Captivate as intended, the
action you describe can be captured easily, and with amazing
clarity and real-time appearance of your actual activity. This is
not really the place to conduct a complete seminar on the product,
but there are more than a half-dozen tutorials (created in
Captivate) accessible on the main user interface (UI) - look in the
right-hand column on that UI. The titles tell you what each
contain. There is also a sample movie or two that was included with
the install. You might find it helpful to open that and after
looking at the timeline and other features, use the Preview feature
to see what a Captivate movie looks like.
After looking at some of those resources, come on back here,
as you will probably have more specific questions we can help with.
Best of luck to you.
