Hi to All,
To capture screen from computer you have 4 major softwares to do this kind of work plus at least 1 NLE video software.
Consider to use one of these softwares: ( the best is the one you like to use after evaluation and money you are ready to invest)
1) Camtasia Studio version 7 or just the Snagit or Jing ( money you are ready to invest from free to $299)
2) Adobe Captivate 5 cost much more $599 but good
3) Qarbon
4) Demo Builder
5) This web site show all: http://www.swftools.com
With time you can use one or 2 different capture solution depend nature of your work to do.
The NLE solution is Magix Movie Edit Pro 17 Plus may be more but the only one I tested.
Regards,
