We had a similar need, because you do an analysis for a customer or even within the company, and you want to be able to send the results around, put them in presentations, etc. I looked at a number of different packages to do the screen capture, and settled on Camtasia. It met our needs on a number of points: (1) Easy to edit. You usually want to just get a "cycle" of the deformation results, and it's pretty simple to get that. (2) It outputs to lots of formats, AVI, WMV, Flash, or MOV. This makes it easy to put stuff into presentations. (3) You can put watermarks on the files, like your company logo, or you could annotate the film to point out the interesting analysis results. The program is commercial, so you have to buy a license, but we've found it useful.
