Singular Software, best known for its PluralEyes video-synchronizing software, has leveraged that technology into a new product now available for Final Cut Pro called Presto. The program takes separately-shot videos of a slideshow presenter, along with the screen showing their slides and a copy of the original slideshow and marries them all together so that the presenter's image remains at the bottom-left of the screen, beside crisp, clear images of the slides, all in sync.
