There used to be an export tool in Digikam in order to create a slideshow presentation as a movie file but that is not present any more. It would be great to have this back. I use ffDiaporama as a workaround. The current slideshow functionality in Digikam is great; it would be even better if we could save the resulting slideshow as a movie file.
