5. To change the appearance of the captions and subtitles, choose from the available styles:
   • Default
   • Classic
   • Large Text
   • Outline Text

   

6. A preview of the selected style will appear in the image at the top of the window.
7. If you would prefer to create your own styles for subtitles and captions, click on the + (plus) button.
   
8. Create your new style from the options available. When you are happy with your custom settings click OK.
9. If you prefer captions intended for the deaf and hard of hearing tock the checkbox for Prefer closed captions and SDH. By checking this option, the system will display captions by default whenever they are available.

Note: If this does not work it could be because someone else manages your computer settings (an IT department or administrator). If this is the case, you will need to contact them to access these settings or for further help.
