View full screen

Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.

 

When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.

Improving the quality of a video

To improve the quality of a video, first click on the Settings icon:

Click on Quality as shown to bring up the submenu.

 

The higher the number you choose, the better will be your video quality (but the slower the connection speed):

Connection speed

Don't choose the HD option unless you have a fast enough connection speed to support it!

 

Is your Wise Owl speaking too slowly (or too quickly)?  You can also use the Settings menu above to change your playback speed.
