tvOS provides a really nice set of customization options for subtitles that lets you set background style, color, font, etc. systemwide. So you set it once (in Settings > General > Accessibility > Subtitles and Captioning > Style) and then that’s how you’ll see subtitles everywhere - YouTube, NetFlix, Amazon Prime, iTunes, all use those settings. But not, apparently, Infuse.
Infuse has its own subtitle display options, that do some of the same things but not all. For example there doesn’t seem to be a “transparent background” setting.
Is there a way to set Infuse to use the systemwide subtitle settings like every other app?
This is something we’re considering for a future update, but in the meantime you can show your support for this by voting for the thread found in the suggestions section.
