Loss in video quality

Question

Hello all,
I wrote a program which display several screens one after an other in a loop.
One of these screen displays a video using JMF. The first time this video is displayed the quality is perfect but the second time and the next times the loss in quality is awful : the video is very "pixeled" and very bad-looking.
Here is the main part of the code I used :
public Screen3() {
          try {
               File file = new File(Main.gui.screenPath5.getText());
               Player p = Manager.createRealizedPlayer(file.toURI().toURL());
                     Component c = p.getVisualComponent();
          catch (Exception e){               
          GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
          GraphicsDevice gd = ge.getDefaultScreenDevice();
public void play() {
          p.start();
          JFrame jFrame = new JFrame();
               jFrame.add (c);
          jFrame.setIgnoreRepaint(true);
          jFrame.setUndecorated(true);
          gd.setFullScreenWindow(jFrame);
     }Each time I want to display the video, I create a new instance of Screen3 and I launch the method play().
The first time it is perfect, then it is bad... Weird isn't it ?
If someone can help me, I would be very grateful.
Thank you in advance.
Best Regards.
Gregory Pierre.

You'll want to create a new comp that's the size and frame rate you want for your web video. Then Drag your full sized comp into the new one and scale it to fit. Make sure that the X and Y scale values are equal. You may also want to do some cropping here. If you then need a little sharpening you can do it here by using an unsharp mask. Now render your new comp.
I almost forgot to mention that if your video footage is interlaced you have to make sure that you've separated fields. You can't move or scale interlaced video without significantly softening the image.
