Soundslides is a great multimedia tool for journalists to tell stories. We have posted about it before on this site. While it is a great program, there are times when people want to take their slideshow and turn it into a single video file rather than the multi-layered structure it natively exports to.
The converter can be found here: http://video.soundslides.net/converter/
While this is a nice tool, it does not work with the demo versions of the program and you will lose some of the slideshow features such as the ability of users to turn off and on captions.
