/**
 * @class   vtkGenericMovieWriter
 * @brief   an abstract movie writer class.
 *
 * vtkGenericMovieWriter is the abstract base class for several movie
 * writers. The input type is a vtkImageData. The Start() method will
 * open and create the file, the Write() method will output a frame to
 * the file (i.e. the contents of the vtkImageData), End() will finalize
 * and close the file.
 * @sa
 * vtkAVIWriter
