Subtitle settings are no longer inside the Viki app
Our subtitles are now using the device iOS settings, which you need to set once before opening the app. You can change size, style, background, color, etc.
Set the subtitle preferences
To turn on subtitles, do the following:
- Go to Settings > General > Accessibility.
- Scroll to the Media section and tap Subtitles & Captioning.
- Turn on Closed Captions + SDH.
You can customize the style of the subtitles like this:
Go to Settings > General > Accessibility > Subtitles & Captioning > Style.
You can select one of the predefined styles: Default, Large Text, or Classic. Or to create your own style, select Create New Style. You can change the font, size, and color of the text along with the color and opacity of the background. To view your new style in full screen, tap the full screen icon 
.
If you want to make sure that your custom style is used for all videos that you watch on your iPhone, iPad, or iPod touch, turn off Video Override at the bottom of each custom options screen. If you don't turn off Video Override, your custom style might be overridden by a video's default settings.
When you're happy with the new style, tap Save at the top of the screen. This style will be the default style for subtitles and captions.
