mpeg encoder is missing from kipi-plugins package, see
That page is out-dated it seems, mpegencoder is no longer included.
According to the kipi-plugins README:
Not yet ported to Qt4/KDE4:
CDArchiving : A tool to archive your image collections to a CD or DVD.
MpegEncoder : A tool to create an MPEG slideshow with a set of images.

Shame: Both imagination and smile are buggy - there is not a good tool for creating a MPEG slide-show at the moment.
