well, i am not quite sure but i think you can try
ACA capture PRo....
ACASystems - Screen Capture & Recording, free download
it is pretty good to me.and i think it can help you out as well....
ACA capture PRO is a multi-function software...Not only capturing the video,
it can capture almost all kinds of files such as swf, all static images, flash on the website, window's menu item...Moreover, ACA capture PRo support selected-area capture function, it is mean that you have a more
flexible screen capture resolution.....
