+The Qt driver provides one of the easiest ways to make a movie.
+Of course, you first need to add the Qt libraries and link with Qt,
+but once you have that, Qt provides a ready-made function to store all updates of the OpenGL
+frame into the movie format.
+You then use loops (as defined in OGLX section above) or even move/rotate/zoom you scene
+by mouse actions to form your movie.
+</para>
+<para>
+The Qt driver automatically handles all of the movie-making steps described in the OGLX section of this document - storing the files, converting them and assembling the finished movie.
+You just have to take care of installing an mpeg_encoder.
+</para>

+To make a movie :
