ImagEmovie is the name of project that allows to create a movie from simple pictures.
The program is available in sourceforge: https://sourceforge.net/projects/imagemovie/
It's possible to add transition between two pictures, insert animated text and perhaps the most interesting, it the possibility to zoom and pan along the picture with the Ken Burns effect.
