Soft to convert Power Point files into video

Guys, I tried to use Jing, but after saving the file it always has this youtube like "play" light-box over the presentation.

Are there any free / cracked software to do it?

I downloaded few on cnet to try, both don't pass VirusTotal - more than 3 warnings on each.

Any advise?

Camtasia 7 is available for fr** if you know where to look and fairly straightforward for producing videos from powerpoint.

PowerPoint 2010 automatically make WMF video.
