Conversion of spj files to mp4 file format

The only way to access or export .spj files (slideshow project) to actual video file (for example .mp4) would be to use the Photostage Slideshow Maker, the very same program that was used to produce the .spj file in the first place. You will most likely also need the original multimedia data, as projects typically do not contain multimedia data, just references to it.
