Use subtitles and captioning in the Apple TV app
If you prefer specific accessible captions, such as subtitles for the deaf and hard of hearing (SDH), you can set the Apple TV app to show them instead of standard subtitles and captions. You can also customize the look of subtitles and captions.
Note: Not all videos include closed captions. This feature may be disabled on devices that already include built-in closed captioning. See your device’s user guide for more information.
Turn on closed captions and SDH
In Settings in the Apple TV app , go to Accessibility > Subtitles and Captioning.
Turn on Closed Captions and SDH.
Turn closed captions on or off during video playback
Follow the instructions in Turn on subtitles and closed captioning (if available).
Customize your subtitles and captions
In Settings in the Apple TV app , go to Accessibility > Subtitles and Captioning > Style.
Choose an existing caption style, or create a new style based on your choice of:
Font, size, and color
Background color and opacity
Text opacity, edge style, and highlight
