No, it's correct: the prototype of setMovie is
  void QLabel::setMovie ( const QMovie & movie ) [virtual slot]

I did specify inter-frame delays but they don't solve the problem. However, I 
found out that setting the background color of the QMovie to black with
  titleMovie->setBackgroundColor(QColor(0, 0, 0));
solves the problem!
