使用PathTransition的javafx动画并不流畅

Question

我正在学习javafx.animation。我创建了一个椭圆和一个矩形，并沿着椭圆的边界进行矩形移动。我让这个动画无限重复。问题是动画圈之间的过渡并不顺畅。这意味着在第一轮动画结束后，下一轮动画开始需要相当长的时间。这看起来很难看。反正有没有让它更顺利？

提前谢谢。

        Ellipse ellipse = new Ellipse(300, 300, 100, 200);
        ellipse.setFill(Color.BLACK);
        Rectangle rect = new Rectangle(50, 80);
        rect.setFill(Color.CRIMSON);
        pane.getChildren().addAll(ellipse, rect);

        //create animation
        PathTransition path = new PathTransition(Duration.millis(2400), ellipse, rect);

        //set up stage
        Scene scene = new Scene(pane, 600, 600);
        stage.setScene(scene);
        stage.show();
    }
